There are a couple of issues with your example.

The Exodus reader creates a multi-block dataset, whose first block is itself a multi-block dataset (You can see that in ParaView's Information tab).

thus, your input should be:

contours.SetInputData(reader.GetOutput().GetBlock(0).GetBlock(0))

second, you need to tell contours which variable to use:

contours.SetInputArrayToProcess(0, 0, 0, 0, "u")

Thank you, this fixed by problem. I have another related question.

I am working on a data set that has multiple subdomains, so
"reader.GetOutput().GetBlock(0).GetBlock(1)" also exists. Do I need to
create two vtkContourFilters to show both subdomains, or is it possible to
setup two input ports on the vtkContourFilter. The latter doesn't seem to
work (I can send a script if this should work).

Thanks again,
Andrew

Subject: [vtkusers] Updating data in a vtkChartXY
Message-ID: <CAMikMhDVn3xyZpgzgdF-KiKuXQroEwt4h3oB4xe4qcuVfjneoQ@mail.gmail.com>

Hi all,

I'm using vtkChartXY to plot some data.

I now need to update the data that is displayed but I'm having trouble
doing so.


Some people were able to call ClearPlots() to recreate the plot. This is a
bit problematic since I have multiple lines on my figure. I was able to
refactor my code to store the line properties (color, width, etc.) and
re-apply them after they are added back to the figure. See for example
those:

http://public.kitware.com/pipermail/vtkusers/2012-March/073136.html
http://vtk.1045678.n5.nabble.com/Cannot-update-vtkChartXY-td5734681.html
http://vtk.1045678.n5.nabble.com/How-to-update-a-2d-plot-vtkChartXY-with-new-data-online-using-C-td5725677.html

Since I have multiple lines, I found it easier for now to store a
std::vector<vtkSmartPointer<vtkTable> > and a vector of my line class. So
to update line index "tableToUpdate", I do something like:

const int prevNbRows = table[tableToUpdate]->GetNumberOfRows();

// FIXME: Don't insert one row at the time!

size_t j = prevNbRows;

for (int i = 0 ; i < x.size() ; i++) {

    table[tableToUpdate]->InsertNextBlankRow();

    table[tableToUpdate]->SetValue(j, 0, x[i]);

    table[tableToUpdate]->SetValue(j, 1, y[i]);

    j++;

}

chart->ClearPlots();

for (int k = 0 ; k < lines.size() ; k++)

{

    lines[k].linePtr = chart->AddPlot(vtkChart::LINE);

    lines[k].RestoreLineProperties();

    lines[k].linePtr->SetInputData(table[k], 0, 1);

}


I have three questions.

1) Does the ClearPlots() frees all memory used? What happens to the
previous linePtr? Are they free? If I update the figure thousands of time
for a "large" number of lines, is there a risk of a memory leak somewhere?
How to properly free the resources?

2) Is there a better way to update a single line out of many? Without
memory leaks?

3) Most importantly, this breaks setting the axis range. For example, doing
this after a line update:

chart->GetAxis(vtkAxis::BOTTOM)->SetRange(minval, maxval);

will change the axis values, but the lines look exactly the same as before
this "zooming".

Maybe it has something to do with how I put everything together:

vtkSmartPointer<vtkRenderer> vRenderer =
> vtkSmartPointer<vtkRenderer>::New();
> vtkGenericOpenGLRenderWindow *renderWindow = GetRenderWindow();
> renderWindow->AddRenderer(renderer);
> vtkSmartPointer<vtkContextScene> chartScene =
> vtkSmartPointer<vtkContextScene>::New();
> vtkSmartPointer<vtkContextActor> chartActor =
> vtkSmartPointer<vtkContextActor>::New();
> vtkSmartPointer<vtkChartXY> chart = vtkSmartPointer<vtkChartXY>::New();
> chartScene->AddItem(chart);
> chartActor->SetScene(chartScene);
> renderer->AddActor(chartActor);



Any ideas or suggestions?

Thanks!

Nicolas

Subject: [vtkusers] Recent Change to Handling Coincident Geometry
Message-ID: <CANXz0SY0bmWcoUxqEMtY-yn3qKKhpBpO8PWzK28sG5X6eQgJ5A@mail.gmail.com>

I wanted to take a second to write up a recent change I made to how VTK (on
the OpenGL2 backend) can handle coincident geometry.  Previously VTK
supported global values for specifying a polygonal offset to push surfaces
forward or back in the zbuffer. This was often used to draw a surface back
a bit in the zbuffer, and then draw the same surface in wireframe mode at
the normal z location. The result was a wireframe overlaid on top of the
surface. This approach faced a couple limitations. Every surface was offset
the same amount and there was no way to offset points from lines.  To
address this I have added a few methods to vtkMapper to specify global line
and point offsets as well as ivars to hold local offsets per mapper. The
global methods look like:

  static void SetResolveCoincidentTopologyLineOffsetParameters(
    double factor, double units);

while the instance methods look like:

  void SetRelativeCoincidentTopologyLineOffsetParameters(
    double factor, double units);

Both signatures use two parameters which are worth mentioning. The first
factor is how much to shift the zbuffer based on how quickly the z values
of the surface or line changes. This may seem complicated but it addresses
a simple issue.  Due to rasterization issues, surfaces and lines with sharp
zvalue slopes are more prone to noise in the zvalues they produce. To
combat that, we offset them by an amount that is based on their z slope. If
the surface is perpendicular to the view direction the factor is
irrelevant, but the more the surface is at a sharp angle to the view
direction, the more the factor comes into play. A value of 1.0 to 2.0 is
fairly typical for the factor. The second parameter is the units, a
constant offset to the zbuffer. It is currently specified conservatively in
terms of a 16bit zbuffer for the OpenGL backend so a value of 1.0 to 2.0 is
a good place to start. For rendering points we do not have a slope so those
methods only take the units argument.

I have changed the global defaults so that surfaces are offset at 2.0,2.0,
lines are offset at 1.0,1.0, and points are at 0.0. There is a new test in
OpenGL2/Testing/CXX/TestCoincident.cxx that renders points on top of lines
on top of a surface while rendering the points first and the surface last
(the opposite order of their visibility).

Thanks
Ken

+1 Ken. The global has caused some surprises in the past. I guess if we
have the global and instance specific setting, then the instance setting
overrides the global setting is what I am assuming you have. Does it reset
to global for the next mapper?

Yes, there were a few examples that set different values on different
mappers not realizing they were both setting the same global and so the
first call was having no effect.

The instance value gets added to the global value. The idea is that there
are some 3D widgets etc that want to float on top of whatever they are tied
to. If the program has set a global offset then those widgets want to be
offset relative to that global offset (and potentially the instance offset
of what they are tied to).

>> I am working on a data set that has multiple subdomains, ...

this is a classic textbook problem.

I would use a vtkExtractBlock(), and a vtkCompositeDataGeometryFilter() to pull all the pieces together.

blocks = vtk.vtkExtractBlock()
blocks.SetInputConnection(reader.GetOutputPort())
blocks.AddIndex(2) # first block is index 2 (starting at 0 for the multiblock dataset container)
blocks.AddIndex(3) # second block

contours.SetInputConnection(blocks.GetOutputPort())

compGF = vtk.vtkCompositeDataGeometryFilter()
compGF.SetInputConnection(contours.GetOutputPort())

contMapper.SetInputConnection(compGF.GetOutputPort())

Hi Aashish,

Do you have any rough estimation on when this could be adressed or not?
For example is it excluded for VTK 8 ?

Thanks,

Hi VTK users,

VTK6.3 seems to build fine using CMake 3.0.2 while using latest CMake
version (3.4.0), cmake gives some errors and won't build using same setup.

Hi,


I am using VTK 6.3 with CMake 3.4-rc3 version, and I have no issues with the compilation. Can you share the error messages you get? Which operating system you are working ?


Best Regard

Hmmm. This is not supported by the piece support in the vtu format. That is
designed so that multiple partitions can be written to the same file. At
read time, the reader actually appends them to a single unstructured grid.

There are three ways of achieving what you'd like:
* Use the vtm format
* Use the Exodus format
* Use Xdmf format

The vtm format is the simplest. A simple XML format that points to a vtu
file per block. It has the disadvantage that these blocks cannot share
point coordinates - each file is stand-alone. If you need that, I highly
recommend using the Exodus II format. It is well documented and has a nice
API. As long as it supports all the cell types that you need of course. The
documentation is here:

http://sourceforge.net/projects/exodusii/files/Documentation/Documentation/

Best,

Subject: [vtkusers] Migration to VTK6
Message-ID: <CAPEs=C9-aWPUZGM0CVcW9gwYui7sXYuxHawFNteY5phhQoyDEw@mail.gmail.com>

I am trying to update my code to migrate to VTK6 according to:

http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Removal_of_Update

According to the examples on that site, I understand that:

    vtkDataObject* dobj = someAlgorithm->GetOutput(1);
    dobj->Update();

should become:

    someAlgorithm->Update(1);


However, I don?t know how to deal with the following pattern:

void PointAreaComputer::WriteIntoFile(char *fileName)
{
    vtkPolyDataWriter* writer=vtkPolyDataWriter::New();
    writer->SetFileName(fileName);
    m_mesh->GetPointData()->SetScalars(m_pointsArea);
    writer->SetInputData(m_mesh);
    writer->Update();
    writer->Write();
    writer->Delete();
}

What should I do to make this compatible with VTK6?

Jean,

Thank you so much for this information, I hadn't run across vtkExtractBlock
until now; it opens up so many possibilities for the work I am doing. I was
able to do want I needed with contours and much more!

Peace,
Andrew

I have several Python VTK scripts for working with Exodus files and volume
rendering, is there some documentation somewhere explaining how to submit
new examples? I would like to contribute back to the community.

Making copies of the tree is a very bad idea as the locator stores a lot of extra info for accelerating ray-traces. 

If you could send a stack trace of where you are getting errors I might be able to suggest something. I had a quick look over the intersection code (which I wrote originally back in 1997 or thereabouts - so I'm a bit rusty with it) but I do not see any obvious misuses of vars. The initial build tree is not thread safe, so you should ensure that two threads are not calling the first ray intersection simultaneously if buildtree has not already been called.

Subject: [vtkusers] Deep copy of vtk Object vtkModifiedBSPTree

Hi

I wish to use vtkModifiedBSPTree with OpenMP by making copies of vtkModifiedBSPTree instances local to each thread but there does not seem to be any methods to copy this object. I naively thought that all vtk objects would have ShallowCopy() or DeepCopy(). I have to do this because using IntersectWithLine() in different threads for the same object instance causes crashes. Is there a solution to this?

Hi Berk



Thank you for your very helpful answer. Of the little I can find on the vtm 
file it would seem to be indeed the natural solution. Would there happen to 
be some documentation of the vtm format?



In parallel computation we are using the .pvtu format which wraps the 
individual .vtu files to a single entity. Would this .pvtu file be in some 
way compatible with the .vtm file? Or should we make the vtm format also 
include the parallel pieces?



BR, Peter

Subject: Re: [vtkusers] Naming of different pieces in VTU format



Hmmm. This is not supported by the piece support in the vtu format. That is 
designed so that multiple partitions can be written to the same file. At 
read time, the reader actually appends them to a single unstructured grid.



There are three ways of achieving what you'd like:

* Use the vtm format

* Use the Exodus format

* Use Xdmf format



The vtm format is the simplest. A simple XML format that points to a vtu 
file per block. It has the disadvantage that these blocks cannot share point 
coordinates - each file is stand-alone. If you need that, I highly recommend 
using the Exodus II format. It is well documented and has a nice API. As 
long as it supports all the cell types that you need of course. The 
documentation is here:

Hi,

I'm writing a VTU (unstructured XML format) writer for a finite element
software (Elmer) in Fortran. This works otherwise great but I would like
to write different parts of the mesh as different pieces, and hopefully
also name the pieces. The idea is that the piece could be selected in
visualization (with Paraview, ViSit etc.).

I attach at the end a working example of the current output. The data is
appended in binary format (if not saved in ascii).

Now ideally the Piece field could take a name, e.g.

<?xml version="1.0"?>
<VTKFile type="UnstructuredGrid" version="0.1" byte_order="LittleEndian">
  <UnstructuredGrid>
    <Piece NumberOfPoints="524" NumberOfCells="150" Name="PartA">
     ...
    </Piece>
    <Piece NumberOfPoints="233" NumberOfCells="117" Name="PartB">
     ...
    </Piece>
  </UnstructuredGrid>
<AppendedData encoding="raw">

Am I hoping too much? The documentation didn't mention the Piece having
the possibility to name it.

Our current approach is to use CellData "GeometryIds" which gives a number
for each different body and boundary condition. Then one can use the
"Threshhold" filter in Paraview to pick data just related to certain
entity. However, this is rather cumbersome particularly if the interesting
entities do not have indexes following each other.

Another motivation for saving data piece by piece is that it will be
easier to introduce discontinuities in the mesh. Then within each piece
the data can be saved as continuous while jumps only appear where the
material changes. If one assumes discontinuity over all elements the
amount of data quickly explodes as the nodes can be shared by tens of
elements.

Could the pieces strategy work, or is there a better way? Any suggestions
are welcome!

-Peter

Hi Cory
Hi Johannes

Is there anything new regarding the crash? I can reproduce the problem with
Jo's sample program for vtk-6.2.0 and vtk-6.3.0. However, the problem does
not occur in 5.10.1. (Tested on Mac OS 10.7, everything compiled with clang
6.0, I've built vtk from source.)

Switching back to vtk-5 is connected to quite some effort on my side, so I
was wondering how to fix or work around the problem with vtk-6.

Let me know if I can support you in a way.

Thanks,
Norman

Okay, I get the clue. I quickly checked it out on my code and it seems to
work. The array data is preserved if both inputs are sharing it.

Arno,

That pattern should be valid in VTK6. Are you getting compile errors?

I believe the Update() and Write() calls to the writer are redundant - you
should need only one.

I agree with Cory on Update() being redundant before the Write().

>    vtkDataObject* dobj = someAlgorithm->GetOutput(1);
>    dobj->Update();

should become:

  someAlgorithm->Update(1); //to make sure there is something valid
  vtkDataObject* dobj = someAlgorithm->GetOutput(1); //keep the output for
later use

Because since vtk6, dobj no longer has any connection to the algorithm, so
updating it (which used to update the algorithm for you) no longer has any
meaning.

All,

Has anyone written (and shared a step/iges) writer for VTK? I found a
couple questions about this forum with no answers.

P. S. stl files do not work for me. I need them in step/iges format.

Hey guys

i'd like to ask you if there's a equivalent method for vtkRenderWindow

vtkAxesActor be helpful?

I hope you can help

Hi John

Thank you for your reply. Please let me make sure I understand your 
statement by asking a question: Are you saying that only the first call to
bspTree->IntersectWithLine(P1, P2, tolerance, points, cellIds); should 
be protected because some allocations or other housekeeping occurs and 
that subsequently many threads can call IntersectWithLine() at the same 
time?

Regards

N.

The initial build tree is not thread safe, so you should ensure that two threads are not calling the first ray intersection simultaneously if buildtree has not already been called.

I was trying to say that on the first call to intersect, if the tree has
not been built, it will be built - and the build routine is not thread
safe for sure. So call ForceBuild first, or make sure that the first call
to intersect only happens on one thread.
I?m not saying the intersect routine is thread safe, but at least
eliminate the obvious cases first.

Subject: [vtkusers] Expanding/Dilating a threshold
Message-ID: <CAK9qV-aKkjBFNgf_s=sAOj77vE1haEZqW5Wm8a_YDCFgcT6xog@mail.gmail.com>

VTK List,

Hi-I'm trying to perform a function that I can't seem to figure out in
VTK.  I'm using Python and I'm trying to perform a threshold function on
vtk Image Data with an expansion caveat.  Currently I can threshold a 3D
block of cells with no problems.  What I want to do is expand that
threshold with a kernel value that I decide (even 1 would be fine for
now).  So the idea would be something like this (2d example to make it
easier to see):

Given a small set of values in a 2D vtkImageData:
001520
015553
015500

If we did a threshold of > 3, we get an unstructured grid as follows:
 5
555
55

This works great in VTK.  What I want to do is include neighboring cells,
which would result in a threshold like this for a value of 1:

  152
 15553
 1550

Is this possible in VTK?  I've looked at the vtkImageDilateErode3D
function.  The example doesn't quite work for me because it sets the Erode
and Dilate values to a specific value (0 and 255), whereas my values aren't
consistent and I need to include them based on their spatial relation, not
their value.  The example I'm referring to is at
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/ImageDilateErode3D

Any help would be appreciated!

Stephen

I was just checking into this, because you shouldn't need to call
ClearPlots at all... I wrote code to determine when to update the
cached data, pack it, perform any necessary conversions. We try to be
conservative as it can be quite expensive, and on re-examining I
wonder if we missed an importan criteria.

That said, I changed a Python test, an dwas able to modify the data in
place in the vtkFloatArray objects, then call Modified() on the
vtkTable, and upon calling Render() on the view I saw the updated
data.

Does that not work for you? We check if the table and some other
things changed since our last build of the cache, the relevant code is
in vtkPlotPoints.cxx for both line and point plots.

It should, vtkObject derived classes are implicitly reference counted.
There is always a risk of a memory leak due to an undiscovered bug,
but this should not leak. We use a flag to highlight leaks when
testing, and so you should be pretty safe.

I think calling Modified() on the table will likely cause all of your
plots to update their internal cache. I think this porbably needs to
be improved to look at the mtime of the component arrays rather than
the top-level table, but you should be able to modify the array in
place, call Modified on the containing table, and Render on the view.

You can change the axis to vtkAxis::FIXED to cause that axis to never
rescale, it is SetBehavior or similar method on vtkAxis.

I would use vtkNew to reduce the repetition of class names in
initialization, but hopefully what I described above will be helpful.

Subject: [vtkusers] ActiViz .NET alternatives
Message-ID: <CAKwjq2xJpNw7HqFVvE9RUgR7fd_EtQj6KbKjwtW3GF+rep=EFw@mail.gmail.com>

Hi. I have an assignment that's really driving me crazy. I'm supposed to
make a program that has a GUI from .NET and graphics from VTK. If I look
on-line, everything says to use ActiViz NET to integrate these. And I would
gladly do this, except the assignment specifically says not to use
ActiViz.NET. I don't know of any practical reason for this, so I assume
it's supposed to make it more challenging.

The graphics part is pretty simple--just rendering some basic 3D shapes.
I'd need to set the background and shape colors, plus render shapes with a
particular position, size, and rotation. Is there any sort of ActiViz.NET
alternative that would do that, maybe even a limited implementation someone
did for practice, school, etc.? I should be able to use that as long as the
license allows it.

On the other hand, is there a simpler way to use these together that I'm
just not thinking of?

Thanks for any suggestions!

I just realized that what I wrote a few minutes ago was wrong.

If you are calling intersect on one thread at the start, then the build cells has completed and it is inside GetCell that the crash is occurring. Inside the BSP tree we are using the same GenericCell object, and that is why you have errors. This is not thread safe.

What you need to do is create a vtkGenericCell for each thread, and modify the Intersect call to accept the generic cell as an input param so that it can use your copy on each thread and not the internal one shared between threads.
It should be fairly trivial, but there might be other internal vars that are also being shared, in which case you might need to substitute other vars.

If I have time, I'll create a patch, if you start on one, send it to me.

NB. The same intersection code is present in other locators (vtkCellTreeLocator for example), so I'll ponder a general solution which can be made part of a bigger fix for the whole locator family. I have a number of patches sitting in my local vtk clone for other things with the locators which need tweaks so I'll look into it.

Subject: [vtkusers] Problem using vtkTerrainContourLineInterpolator
Message-ID: <1449228381808-5735312.post@n5.nabble.com>

Hi folks!

I have a serious problem regarding vtkContourWidget using
vtkTerrainContourLineInterpolator. 
I have to modify an area identified by a few vertexes, when I select one of
these vertex, and try to move it upon a 3D Actor, I found an infinite loop
inside vtkTerrainContourLineInterpolator::InterpolateLine method in bold
sentences. In particular, I really don't know what is that tolerance (I
think it's the maximum distance between two points in order to insert an
intermediate point to draw the line), because the boolean value
traversalDone (when infinite loop occurs) is never set to true, and RAM
memory increase significately till application crash.

  const double tolerance = *1.0;*
  bool traversalDone = false;
  while (!traversalDone)
    {
    for (interpolatedCells->InitTraversal();
         interpolatedCells->GetNextCell(npts, ptIdx); )
      {

      double p[3];
      interpolatedPts->GetPoint(ptIdx[0], p);

      if (*(p[0]-p1[0])*(p[0]-p1[0]) + (p[1]-p1[1])*(p[1]-p1[1]) <
tolerance*)
        {
        interpolatedPts->GetPoint(ptIdx[npts-1], p1);
        if (*(p2[0]-p1[0])*(p2[0]-p1[0])
            + (p2[1]-p1[1])*(p2[1]-p1[1]) < tolerance*)
          {
          --npts;
          traversalDone = true;
          }

        for (int i = 1; i < npts; i++)
          {
          rep->AddIntermediatePointWorldPosition(
              idx1, interpolatedPts->GetPoint(ptIdx[i]) );
          }
        continue;
        }
      }
    }

  return 1;

I have this pipeline (I create these objects
   vtkContourWidget*                      m_pContour;
   vtkOrientedGlyphContourRepresentation* m_pRepresentation;
   vtkTerrainContourLineInterpolator*     m_pInterpolator;
   vtkTerrainDataPointPlacer*             m_pPointPlacer;

and I use vtkProjectedTerrainPath as the Projector contained inside
vtkTerrainContourLineInterpolator, I do not create a separated object for
it).

// Configure the vtkTerrainContourLineInterpolator
m_pInterpolator->SetImageData(l_pStructuredPoints);
vtkIdType l_iNumberOfLines = DEFAULT_MAX_INTERPOLATOR_LINES; (could be
100000 or 100, the problem is still present)
m_pInterpolator->GetProjector()->SetMaximumNumberOfLines(l_iNumberOfLines);
m_pInterpolator->GetProjector()->SetProjectionModeToHug();
m_pInterpolator->GetProjector()->SetHeightOffset(3);
m_pInterpolator->GetProjector()->SetHeightTolerance(0.1);

// Configure the Point Placer
m_pPointPlacer->RemoveAllProps();
m_pPointPlacer->AddProp(m_pDtmActor);

// Configure vtkContourRepresentation
m_pRepresentation->GetLinesProperty()->SetLineWidth(2.0);
m_pRepresentation->GetLinesProperty()->SetColor(1, 0, 0);
m_pRepresentation->SetLineInterpolator(m_pInterpolator);
m_pRepresentation->SetPointPlacer(m_pPointPlacer);
m_pRepresentation->SetRenderer(m_pRenderer);

vtkSphereSource* sphere = vtkSphereSource::New();
sphere->SetRadius(l_dDtmResolution / 2);
sphere->Update();
m_pRepresentation->SetCursorShape(sphere->GetOutput());
m_pRepresentation->SetActiveCursorShape(sphere->GetOutput());
sphere->Delete();

//Configure  vtkContourWidget
m_pContour->SetRepresentation(m_pRepresentation);
m_pContour->SetInteractor(m_pRenderWindowInteractor);

I hope you can understand my problem. 
I'm using VTK 6.1.0 version. 

I'm looking for your kind reply

regards, 

jimmigoo

With modern Visual Studio, you can link unmanaged/native C++ libraries into
.NET assemblies and executables. Have you thought about possibly using a
managed C++ UI built in .NET and just linking in the plain old VTK
libraries? (Not sure if there are any roadblocks here specifically with
VTK, I've not tried it personally, but I have built a managed C++ app which
links in unmanaged libraries...)

Message-ID: <TY1PR04MB06723DA9F13E71E944B86A12D40C0@TY1PR04MB0672.apcprd04.prod.outlook.com>

Dear All,



I tried to build a VTK tube from a skeletonized vessel tree, but unfortunately I got very messy results as shown in the following image. I guess the problem was caused by a false generation of a vtkPolyData from the skeletonized vessel tree since the points in the generated vtkPolyData from different vessel branches were connected with each other.



May I ask what is the way to generate a proper vtkPolyData from a skeletonized vessel tree please?

Thank you very much.



Best regards,

Xiaopeng

I have data like this:
http://i.imgur.com/CR2O8Ik.png
and I would like to "stretch" the Z-axis to get more like a cube 
visualization.

I used vtkTransform to transform the axes, but I would change the data 
if I do this. I hope you understand what I want to do, e.g. is there a 
possibility to change / stretch the ticks of a specific axis.

The vtkTransform plot stretches to much:
http://i.imgur.com/DDUW91T.png
The data is deformed

I use the vtkTransform like this:
vtkSmartPointer<vtkTransform> axis = vtkSmartPointer<vtkTransform>::New();
axis->Scale(1,1,10);

dataActor->SetUserTransform(axis);
outlineActor->SetUserTransform(axis);

I tried using the camera with the vtkTransform, but the only thing I got 
from there, was an empty image or I had to zoom out greatly.

For matlab reference, something like this:
http://de.mathworks.com/help/matlab/ref/axis.html?refresh=true

Would be nice if you could help me

Hi Xiaopeng,

Could you describe how you got this result? Does you input consist of
points only or does it have connectivity information?

Thanks,
Cory

Imre,

Your best bet is probably to transform the data itself rather than the user
transform of the actors.

vtkSmartPointer<vtkTransformFilter> transformFilter =
vtkSmartPointer<vtkTransformFilter>::New();
transformFilter->SetTransform(axis);
transformFilter->SetInputData(<your input data>);

HTH,
Cory

Subject: [vtkusers] Contour of 3D Exodus Data
In-Reply-To: <CAGWYgTk_nhEhptrmZTjdD8s2x3qJWwAiaOoE6gQTjGSjGKK+1w@mail.gmail.com>

By the way, if you want to contour all of the blocks, the following is the
simple way to go:

# Read Exodus Data
reader = vtk.vtkExodusIIReader()
reader.SetFileName('cube_out.e')
reader.UpdateInformation()
reader.SetTimeStep(0)
reader.SetAllArrayStatus(vtk.vtkExodusIIReader.NODAL, 1)

# Contours (these do not show up in my rendered image)
contours = vtk.vtkContourFilter()
contours.SetInputConnection(reader.GetOutputPort())
contours.SetInputArrayToProcess(0, 0, 0, 0, "u")
contours.SetNumberOfContours(1)
contours.SetValue(0, 0.5)

contMapper = vtk.vtkCompositePolyDataMapper2()
contMapper.SetInputConnection(contours.GetOutputPort())
contMapper.SetScalarVisibility(False) # colored contours
contMapper.SetScalarRange(scalar_range)

# actor, renderer etc. here

Note the use of the vtkCompositePolyDataMapper2 instead of the regular
vtkPolyDataMapper.

Best,

The workshop on
High Performance Data Analysis and Visualization (HPDAV) 2016
http://vis.lbl.gov/Events/HPDAV-IPDPS-2016/
May 23, 2016

To be held in conjunction with
30th IEEE International Parallel and Distributed Processing Symposium
http://www.ipdps.org/
May 23-26, 2016
Chicago Hyatt Regency, Chicago, Illinois, USA




Important Dates (AoE)
____________________________________________________________________________________

Paper Submission: Jan. 10, 2016
Paper Notification: Feb. 7, 2016
Camera-Ready: Feb. 21, 2016



Workshop Scope and Goals
____________________________________________________________________________________

While the purpose of visualization and analysis is insight, realizing that
objective requires solving complex problems related to crafting or adapting
algorithms and applications to take advantage of evolving architectures,
and to solve increasingly complex data understanding problems for ever
larger and more complex data. These architectures, and the systems from
which they are built, have increasingly deep memory hierarchies, increasing
concurrency, decreasing relative per-core/per-node I/O capacity, lessening
memory per core, are increasingly prone to failures, and face power
limitations.

The purpose of this workshop is to bring together researchers, engineers,
and architects of data-intensive computing technologies, which span
visualization, analysis, and data management, to present and discuss
research topics germane to high performance data analysis and
visualization. Specifically, this workshop focuses on research topics
related to adapting/creating algorithms, technologies, and applications for
use on emerging computational architectures and platforms.

The workshop format includes traditional research papers (8-10 pages) for
in-depth topics, short papers (4 pages) for works in progress, and a panel
discussion.

Proceedings of the workshops are distributed at the conference and are
submitted for inclusion in the IEEE Xplore Digital Library after the
conference.

We invite papers on original, unpublished research in the following topic
areas under the general umbrella of high performance visualization and
analysis:

- Increasing concurrency at the node level, and at the systemwide level.
- Optimizations for improving performance, e.g., decreasing runtime,
leveraging a deepening memory hierarchy, reducing data movement, reducing
power consumption.
- Applications of visualization and analysis, where there is a strong
thematic element related to being able to solve a larger or more complex
problem because of algorithmic or design advances that take advantage of
increasing concurrency, architectural features, etc.
- Data analysis and/or visualization systems/designs/architectures having
an emphasis upon scalability, resilience, high-throughput/high-capacity,
and that are able to take advantage of emerging architectures.

Stephen,

It sounds like you would need to first create a dilated binary mask, then
mask out your original data.

vtkImageThreshold should let you get the initial binary mask. Then you can
use vtkImageDilateErode3D to dilate the mask. Finally, use vtkImageMask to
pull out the original image masked by the dilated threshold.

HTH,
Cory

Thanks for the suggestion, I have a question regarding
vtk.vtkExtractBlock(). What index does the AddIndex method refer to?

I can't seem to understand the relationship of reader MultiBlock data set
and these indices. (i.e., I can use AddIndex(0) and/or AndIndex(1) and see
the contours on the complete geometry).

I am trying to write a code that, by default, contours all blocks, but the
user can also select to limit the contours to certain blocks. Thus, I am
trying to related the "block" names shown in the reader and the indices
used by vtkExtractBlock.

Thanks again,
Andrew

Norman,

There might be a fix for this in gitlab.

https://gitlab.kitware.com/vtk/vtk/merge_requests/455/diffs

You can try out this branch and see if it fixes the crash for you. You can
get it with:

git fetch https://gitlab.kitware.com/jpouderoux/vtk.git FixDelaunay2DBug
git checkout -b jpouderoux/vtk-FixDelaunay2DBug FETCH_HEAD

Best regards,
Cory

Subject: [vtkusers] Saving custom array class instance to *.vti file
 with time information
In-Reply-To: <1447352677.2990.28.camel@tachikoma-mint>

HI Gael,

Saving each time step to a VTI file is very reasonable in the way that you
are doing it. I would recommend doing that.

To assign times to each VTI file, I recommend also writing a .pvd file,
which is an XML file that describes a list of files that can be loaded by
ParaView. You can describe your VTI files in the .pvd file and assign a
time to each VTI file. Please see

http://www.paraview.org/Wiki/ParaView/Data_formats#PVD_File_Format

for more details on the PVD file.

Hope that helps,
Cory

Excellent!!! The fix works as far as I can tell. Johannes' sample does not
crash anymore, neither does my application (I will do some more extensive
testing next week).

Thanks for the hint. Hope to see the fix in the next release.

I have another question, along the same lines. Is there a similar tool as
vtkExtractBlock for extracting SideSets and NodeSets? Thus. allowing a
single ExodusReader to display blocks, nodesets, and sidesets in multiple
renderers.

Thanks,
Andrew

Is there any way to rip these dependencies out? The application 
I'm supporting is headless and the hardware has no 3d graphics

vtk and ITK except the x11 and GL dependencies are giving me

There is a current merge request that sounds related. Cory would please
check if it does and let us know.

Hi,

I'm not sure how this is related to VTK? VTK has some support for reading
DICOM images, but no support for writing them, so you wouldn't be able to
use VTK to compress DICOM files, for instance.

You might consider looking at DCMTK for working with DICOM files
http://dicom.offis.de/dcmtk.php.en

Subject: [vtkusers] Enlarge dicom's display on iOS
Message-ID: <tencent_25D1F7AE5A686A41045BBE91@qq.com>

Hi developers,


    Now I have a project on iOS with vtk. I try to read a dicom file to display in iPad. It works, but the size of the dicom image is limited. I try to resize the actor and vtkIOSRenderWindow, but no reaction, the following is my codes, Please help me which method can enlarge the dicom display!
 
     vtkObjectFactory::RegisterFactory(vtkRenderingOpenGL2ObjectFactory::New());
 
    
 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
 
    NSString *basePath = paths.firstObject;
 
    std::string fname([basePath UTF8String]);
 
    fname += "/dicom/output_1.dcm";
 
    vtkNew<vtkDICOMImageReader> reader;
 
    reader->SetFileName(fname.data());  
 


 
    vtkNew<vtkImageMapper> imageMapper;
 
    imageMapper->SetInputConnection(reader->GetOutputPort());
 
    
 
    vtkNew<vtkActor2D> imageActor;
 
    imageActor->SetMapper(imageMapper.Get());
 
    imageActor->SetDisplayPosition(500, 1000);
 


 
    imageActor->SetHeight(500);
 
    imageActor->SetWidth(500);
 
    
 
    vtkNew<vtkRenderer> renderer;
 
    renderer->SetBackground(1,1,1);
 
    renderer->GradientBackgroundOn();
 
    renderer->AddActor(imageActor.Get());
 
    
 


 
   vtkIOSRenderWindow *renWin = vtkIOSRenderWindow::New();
 
    renWin->AddRenderer(renderer.Get());
 
    [self setVTKRenderWindow:renWin];




Thank you very much!

Cory,

is it possible to change the tick of the axes? Right know using the 
transform filter is equivalent to the second image. Unfortunately that 
is not what I would like to have. I think the best way to do this is to 
change to tick of the Z-Dimension.

The image has the dimensions 520x520x47. So the tick for x and y is 1, 
for z it should be 47/520. I don't want to change the data.

Dave,

I think you are talking about this MR:
https://gitlab.kitware.com/vtk/vtk/merge_requests/455

Norman tested it and says it solves his issue.

I'll work with Joachim to get this merged in before VTK 7.

Thanks,
Cory

Subject: [vtkusers] Sharing vtkRenderer?
Message-ID: <CAOG35cnp+qapwFOerz=RKcuHgC60D38cJhX8q9XHeEDj7XGXDQ@mail.gmail.com>

Hello users,

Is it possible to share a common vtkRenderer object among multiple
vtkRenderWindows? Or is it that each window should have its own renderer?
What I need to do is show same actor in different windows but with
different projections and viewports. Will sharing a common renderer work in
this case?

Thanks in advance

Subject: [vtkusers] MarchingCubes missunderstandig GenerateValues and
	Contours
Message-ID: <566329DB.7010305@gmail.com>

Hey guys,

I have a question about the "GenerateValues" method of MarchingCubes. My 
image has several points that have intensity values that lie between 928 
and 1600.

My understand of

int idxContour = 1;
double from = 920;
double to = 930;

ImageToVTKImageFilter con = ...

marchingCube->setInputData(con->GetOutput());
marchingCube->GenerateValues(idxContour, from, to);
marchingCube->Update();

is that the algorithm will take all points that have an intensity value 
that lies between 920 and 930. These points are combined to one contour. 
Via MATLAB and ITK's histogram I can validate the amout of points that 
have a specific intensity value.

If I plot the points that were generated by marching cubes, I do not get 
all of them (I cannot see all of them), e.g.
the histogram says that there are about 200000 points that have an 
intensity value 928. If I use 928 as the lower bound for the 
GenerateValues method, there are just some of them plotted - approximately.

Is my understanding of GenerateValues correct?

Next question: (more than 1 contour)

If I want to generate more than 1 contour. How do I initialize the 
marchingCube and, more interesting, how do I get the output of a 
specific contour. I'm thinking about the following:


marchingCube->SetNumberOfContours(2);
marchingCube->GenerateValues(1, from_1, to_1);
marchingCube->GenerateValues(2, from_2, to_2);

vtkSmartPointer<vtkOutlineFilter> outline = 
vtkSmartPointer<vtkOutlineFilter>::New();
outline->SetInputConnection(marchingCube->GetOutput(1));

vtkSmartPointer<vtkPolyDataMapper> outlineMapper = 
vtkSmartPointer<vtkPolyDataMapper>::New();
outlineMapper->SetInputConnection(outline->GetOutputPort());

vtkSmartPointer<vtkPolyDataMapper> data1 = 
vtkSmartPointer<vtkPolyDataMapper>::New();
data1->SetInputConnection(marchingCube->GetOutput(1));

vtkSmartPointer<vtkPolyDataMapper> data2 = 
vtkSmartPointer<vtkPolyDataMapper>::New();
data2->SetInputConnection(marchingCube->GetOutput(2));

I know that the above lines are not working like this, but I actually do 
not know how to do that. Right now I have 2 marchingCube instances that 
do the work for data1/data2 but that should not do the trick.

I hope you can help me

Greetings
Imre

Hi ,

I see vtkCubeAxesActor- but is there a way to draw grid lines just in world space surrounding the actors in the scene?

I guess like matlab's plot3d etc.

Hey guys,

here is a 2D example of what I wanted to do. I think data transformation

So after setting Connectivity and Locations I'm still having empty these members, and when I use
vtkXMLUnstructuredGridWriter, only Points, and CellTypes are contained in .vtu file. (connectivity is empty, and
locations contains rubish numbers). This function works when I use InsertNextCell but this is not parallelizable.
Is it solvable? Thank you for any hint.

Each vtkRenderWindow should have its own vtkRenderer. Also, you cannot
reliably share actors across different vtkRenderers, so each vtkRenderer
should have its own set of actors.

Not exactly. vtkMarchingCubes will extract individual isocontours -
surfaces that represent the locations in a dataset with a particular value.
vtkMarchingCubes and other isocontour filters in VTK can generate surfaces
from more than one isovalue. GenerateValues() is a convenience function to
specify a range of isovalues.

A vtkThreshold filter will extract all points in the dataset in a value
range and may be what you want.

You can't set up two different isocontour surfaces and get two different
outputs this way. Using two separate vtkMarchingCubes instances is the
right way to go.

Hi Rick,

Are you looking for a convenience function somewhere that just
automatically adds axes to the scene? There isn't one that I know of.

If you are looking for a convenience function to get the bounds of all
visible actors in a scene, see the member function
vtkRenderer::ComputeVisiblePropBounds(double bounds[6]) [1].

HTH,
Cory

Thank you Cory,

I implemented the vtkThreshold today, now it is working fine.

Imre,

Have you looked at the charting API, e.g., vtkChartXYZ? I don't know if
that does exactly what you want, but it may be more in line with what you
are after.

Subject: [vtkusers] Problem With Linux+Nvidia Cuda
Message-ID: <CAOnPkwdepks4dN2TjUB4mzTPFBQhirCvYDDMPeh0iL4j8ESUCw@mail.gmail.com>

Hi guys!
Some friends are trying to compile my project, which has VTK code, but in
notebooks with graphics cards using Nvidia CUDA, the project does not run.
Is there any native problem of VTK with Nvidia cards?
Because even uninstalling CUDA, keeps giving error. I dont have a
printscreen of this error, i'm waiting for my friends send to me, but for
now i would like to discuss about...
Thanks!

By "not run", do you mean the project doesn't compile? I have had problems
compiling CUDA code in projects that use VTK when the VTK include directory
(-I) options are handed to nvcc because of nvcc's command-line length
limit. This definitely happens on Windows, and may happen on other
platforms as well.

Hi,

Thanks for your reply. It's just a question. Can't I share actors created
by smart pointer across multiple renderers. ?

Actors store some OpenGL state in the mappers they use. While it appears to
be possible to share some kinds of OpenGL state among the different OpenGL
contexts in the render windows, VTK is not designed with this in mind.
Hence, it is safest to have different actors for different renderers.

HTH,
Cory

So you mean to say that, in an application if I have 4 windows, each window
will have its own vtkRenderWindow, and each vtkRenderWindow will have its
own renderer. Each renderer will have its own set of actors. This means
there would exist duplicate dataset right. ? Maybe this is next issue, how
to handle single dataset among multiple windows. Does this query need a new
thread.?

Thanks

You'll also need different mappers for the different windows.

You can share the data set among the different windows - no need to
duplicate. This is because the data model classes do not have any OpenGL
context-dependent state.

Yes, so I have a common vtkpolydata shared among the four windows. Also
this data will reside in all the mappers/actors right. .? Won't it be a
duplicate. ?

Thanks

No, you will be passing a pointer to the same data to all of the mappers.
The data itself isn't duplicated when you pass a pointer to it to the
mapper.

Hi all,

The fix in question has been merged into VTK master. It will be available
in VTK 7.

On VTK master you can select the "None" backend for rendering. I'm not sure
if that gets rid of all the X11/OpenGL references though.  That would be my
first suggestion to try if you have not already.

Thanks

Hi Pedro,

The vtkPNGWriter supports either 8-bit or 16-bit integral components with
1, 2, 3, or 4 channels (gray, gray+alpha, rgb, and rgb+alpha). If your
vtkImageData uses unsigned short as it's scalar type then the full range
should get saved, so it won't be 10-bit but it will be 16-bit and you'll
still get all your pixels data correct.  That being said, both the PNG spec
and libpng only allow for bitdepths of 1, 2, 4, 8, and 16, so a 16-bit PNG
is the best you'll probably get.  I wouldn't worry about the "wasted space"
from the extra bits as compression should drop that to effectively
nothing.  The consuming application would just need to be aware of the
reduced sample range, i.e. [0:1023] instead of [0:65535].

Hi Mark,

This is common configuration we use to deploy on HPC clusters.  Typically
we will configure VTK with -DVTK_USE_X=OFF and -DVTK_USE_OSMESA=ON.  You
can build your own static libOSMesa.a to link against so you can still get
rendering (albeit slower CPU based rendering) without any X11 dependencies
or shared libraries.

Hi all,

Looking at this post, I think now is a good time to mention that I have been
working on an alternate boolean operation. I realize this was more an issue
with Delaunay 2D, and I actually noticed some of the Delaunay 2D problems
while working on this new boolean, and I worked with Joachim to get those
issues fixed. 

I have just recently finished it up, and I figured maybe it could be added
as a second boolean operation in vtk? It created a very similar
vtkIntersectionPolyDataFilter with a couple small differences. The boolean
however is more similar to the GTS implementation to identify boolean
regions instead of a signed distance algorithm. This improves the speed and
quality, and also allows open surface booleans.

I have created a fork, and I have started to clean up the code for vtk
format. If this sounds helpful and something that might be possible, let me
know!

Thanks!

Adam Updegrove

I'm happy to look into alternate, more robust implementations.

Subject: [vtkusers] volume rendering and animation
Message-ID: <10285631702C4D4CB5C4921DC14337954EE9EA3C@neocoilexch01>

Hello,

I have 3D cardiac MRI data (4D including time domain). I can display volume rendering of the data using vtkSmartVolumeMapper.
When I tried to do animation (CINE) by  changing actors every time TimerEvent occurs, it is slow (using CPU or GPU).
Even when there is no user interaction, vtk seems to perform volume rendering every time actors change.
Are there any way for vtk to not perform volume rendering every time actors change by caching or something?
I was wondering if vtkMultiBlockDataSet or vtkTemporal*** can be utilized, but was unable to find a solution.

Thank you,

Great! I will work at getting it into my fork in the next couple of days, and
then we can work at trying to get it contributed if possible.

If I understand your problem, no there is no direct way. If you have
multiple vtkVolume, and you are not going over the video memory limit,
atleast, data transfer shouldn't happen every time. Are you creating
vtkVolume for each timestamp or do you have only one that you are trying to
re-use?

Subject: [vtkusers] vtkVolumeProperty IndependentComponents On and Off
Message-ID: <10285631702C4D4CB5C4921DC14337954EE9EAD4@neocoilexch01>

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.
My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

"For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function."

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Hello,

I have vtkPolyData containing set of vtkPolygons.
I need to display theese polygons filled with some colour.
And here comes difficulties: if there is one polygon in another polygon, it
means that this polygon represents hole. And this is recursive.

Here is example:
Input: http://postimg.org/image/du9qw1b45/
Output: http://postimg.org/image/pdf8vt3tn/

I have no idea how to do this. Is there any filter for this? I didnt found
any... Please any suggestions?

Thank you,

I don't remember vtkSmartVolumeMapper has this logic, I will have a look.
In the old GPU raycast mapper, there was some issue with independent
components so may be that is the reason that smart volume mapper switched
to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can
directly use GPUVolume RayCastMapper

Hi Aashish,

Thank you.
I tried with vtkGPUVolumeRayCastMapper.
An error occurs without setting IndependentComponentsOff.
It seems  the error occurs in vtkOpenGLGPUVolumeRayCastMapper::BuildShader (See the attached file).

Thanks Kenji for trying out. Its not clear in the log why the build shader
code crashed.
Also, I realized that you using Java bindings. Would it be possible to
re-create this issue
with a small sample code and you send it to me? We do have two component
and 4 component
test (dependent and independent). Please have a look here:
https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTwoComponentsIndependent.cxx

and

Aashish,

Thank you very much.
I will try to run the test example and see what happens.
If the test is ok, I will try to reproduce the problem with simpler code.

Hi Aashish,

Thank you.
I tried with vtkGPUVolumeRayCastMapper.
An error occurs without setting IndependentComponentsOff.
It seems  the error occurs in vtkOpenGLGPUVolumeRayCastMapper::BuildShader (See the attached file).

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.

I don't remember vtkSmartVolumeMapper has this logic, I will have a look. In the old GPU raycast mapper, there was some issue with independent components so may be that is the reason that smart volume mapper switched to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can directly use GPUVolume RayCastMapper

My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

?For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function.?

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Subject: [vtkusers] vtkTriangleStrip
Message-ID: <42b824c7-713d-433e-9088-5bdfd473b886@me.com>


Hi,

I'm building a curved tube from a given set of sampled points using the vtkTriangleStrip class.

It works fine except it seems the last triangle wants to connect to the first, so I have a tube with a surface that loops back to the start.

Is there a way to "disconnect" these? Or perhaps a better way to implement? My code is initially based on the triangle strip example (but with a lot more points of course).

And actually the original code used OpenGL directly?

GL_TRIANGLE_STRIP in a loop.

Thanks

Rick

Hi, Ondrej
If you mean color the individual polygon, you may try:
1. Identify each polygon with vtkPolyDataConnectivityFilter 
2. Determine overlapping order through Boost::Geometry::Polygon, for example

3. I presume your polygons are in 2D space since they are embedded each
other, 
through OVERLAPPING tests you can assign each polygon with a virtual Z
coordinate
denoting depth order, and then let vtkDepthSortPolydata doing the rest
rendering works.

Hi,
you could use ITK and the ImageToVTKImageFilter or the TIFFImageReader

Hi,
    Already I have seen the example of
vtkXMLPolydataWriter(http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/WriteVTP).
It require the input as points. So, I need to get the points or Image data
to write from the TIFF Image or MHA File. If I have Image data, I can write
.vti files.

Subject: [vtkusers] System HDF with bundled NetCDF
Message-ID: <5666C6F7.2050803@univ-nantes.fr>

Hello,

When compiling VTK with system HDF5 and NetCDF from the thirdparty
(because newer NetCDF seems to be incompatible), NetCDF seems to be
disabled as CMake does not find HDF5 in the file
'ThirdParty/netcdf/vtknetcdf/CMakeLists.txt' at line 239.

Is it the normal behaviour ?

Thanks by advance.

What version? We have a dashboard which compiles against a system
4.3.3.1 (with netcdf-cxx 4.2) just fine. You do need the C++ bindings as
well; the VTK netcdf is patched such that both are included (something I
plan on fixing when I get around to updating our netcdf).

It seems that you are missing HDF5's high-level library; it may ship
separately from the base HDF5 libraries (but I don't see separate
packages in either Debian or Fedora).

Message-ID: <1449591363984-5735395.post@n5.nabble.com>

I'm using VTK to manipulate DICOM images series en 3D. I used this mouse
listener to zoom the image : 

    ML_Zoom = new MouseListener() { 
                @Override 
                public void mouseClicked(MouseEvent e) { 
                } 
    
                @Override 
                public void mousePressed(MouseEvent e) { 
    
                    button = (int) e.getButton(); 
                    if (button == 1) { 
                        for (int i = 0; i < 3; i++) { 
                            style[i].EndSpin(); 
                            style[i].EndPan(); 
                            style[i].EndDolly();                       
                            style[i] = new vtkInteractorStyleImage(); 
                            iren[i].SetInteractorStyle(style[i]); 
                            style[i].StartDolly();                     
                        }               
                    }               
                } 
    
                @Override 
                public void mouseReleased(MouseEvent e) { 
                      
                    for (int i = 0; i < 3; i++) { 
                        style[i].EndDolly();

                public void mouseExited(MouseEvent e) { 
                } 
            }; 

How can I compute zoom level ?

Hi Aashish,

Adding gradient opacity to the test sample causes the same error I have seen in my application.
Please refer to the attached file.
So my application works with IndependentComponents On after removing gradient opacity.

Thanks Kenji for trying out. Its not clear in the log why the build shader code crashed.
Also, I realized that you using Java bindings. Would it be possible to re-create this issue
with a small sample code and you send it to me? We do have two component and 4 component
test (dependent and independent). Please have a look here: https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTwoComponentsIndependent.cxx

I tried with vtkGPUVolumeRayCastMapper.

It seems  the error occurs in vtkOpenGLGPUVolumeRayCastMapper::BuildShader (See the attached file).

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.

I don't remember vtkSmartVolumeMapper has this logic, I will have a look. In the old GPU raycast mapper, there was some issue with independent components so may be that is the reason that smart volume mapper switched to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can directly use GPUVolume RayCastMapper

My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

?For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function.?

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Aha... I think I know how to fix the bug.  Gradient opacity was the key. I
will push a fix today.

The version are the following;  VTK 6.3.0, netcdf 4.3.3.1, netcdf-cxx
4.2 and hdf5 1.18.15 on ArchLinux.

When compiling with system NetCDF the following error appears:

Found HDF5:

And when using system HDF and NetCDF from the thirdparty, NetCDF is

Hi Folks,

The mangled PROJ4 in VTK is ancient and no longer supported by anyone else.
Also, it is buggy, since then PROJ4 has moved on fixing bugs and changed
the API a bit as well (includes the named EPSG codes).

Are there any objections to switching to last release of PROJ4? We need
this sometime soon so if you have any feedback please send me/mailing list
an email.

Thanks,
Aashish

If after 7.0 branch you've got my +1.

When we do please do so via Ben's nifty new scripts that standardize and
use best practices for TPL integration into VTK.

No objections. Please port to the new third-party setup in the process
(see zlib, png, and jsoncpp for examples).

Great.. yes.. certainly we can wait that long (it may take atleast 1-2 days
anyways).

Subject: [vtkusers] Broken surfaces for vtkBooleanOperationPolyDataFilter()
	- Bug?
Message-ID: <1449603243012-5735413.post@n5.nabble.com>

Hi, 

For two polydata objects I create boolean operations, and /often/ this does
not cause any problems. However, /sometimes/ I get results as seen in the
image below. The second image shows that there are indeed non-manifold edges
resulting from the operations.

I verified that the input objects are manifold.

I came across  this
<http://vtk.1045678.n5.nabble.com/Non-manifold-triangles-after-running-vtkBooleanOperationPolydataFilter-td5713964.html>  
post where Cory Quammen states it might be related to a bug in the
algorithm.

(I've cross-posted the problem also on  Stackoverflow
<http://stackoverflow.com/questions/34100211>  , but I found that I reach
the vtk cracks much more efficiently through this mailing list.)

I'm calling the following code:

def doApplyCutAdvanced(source, cutCylinder, domeCutCenter):
    '''
    Cut a cylinder B from source A according to the following recipe:
    A = A \ B
    A = connectivityFilter(A, domeCenter)
    A = A v (A ^ B)
    '''
    
    # Extract triangles.
    sourceTriangles = vtk.vtkTriangleFilter()
    sourceTriangles.SetInputConnection(source.GetOutputPort())
    sourceTriangles.Update()
    
    cylinderTriangles = vtk.vtkTriangleFilter()
    cylinderTriangles.SetInputConnection(cutCylinder.GetOutputPort())
    cylinderTriangles.Update()
    
    # First operation: A \ B
    operation1 = vtk.vtkBooleanOperationPolyDataFilter()
    operation1.SetOperationToDifference()
    operation1.SetInputConnection(0, sourceTriangles.GetOutputPort())
    operation1.SetInputConnection(1, cylinderTriangles.GetOutputPort())
    operation1.Update()
    
    # Second operation: A ^ B
    operation2 = vtk.vtkBooleanOperationPolyDataFilter()
    operation2.SetOperationToIntersection()
    operation2.SetInputConnection(0, source.GetOutputPort())
    operation2.SetInputConnection(1, cylinderTriangles.GetOutputPort())
    operation2.Update()
    
    #?Apply the cut.
    cutSurfaceConnected = vtk.vtkPolyDataConnectivityFilter()
    cutSurfaceConnected.SetInputConnection(operation1.GetOutputPort())
    cutSurfaceConnected.SetExtractionModeToClosestPointRegion()
    cutSurfaceConnected.SetClosestPoint(domeCutCenter)
    cutSurfaceConnected.Update()
    
    #?Fix up the source object (if it was cut partially by the cylinder)
    appendFilter = vtk.vtkAppendPolyData()
    if vtk.vtkVersion.GetVTKMajorVersion() == 5:
        appendFilter.AddInput(cutSurfaceConnected.GetOutput())
        appendFilter.AddInput(operation2.GetOutput())
    else:
        appendFilter.AddInputData(cutSurfaceConnected.GetOutput())
        appendFilter.AddInputData(operation2.GetOutput())
    appendFilter.Update()
        
    cutSurfaceRepaired = vtk.vtkCleanPolyData()
    cutSurfaceRepaired.SetInputConnection(appendFilter.GetOutputPort())
    cutSurfaceRepaired.Update()
    
    cutSurfaceRepairedTriangles = vtk.vtkTriangleFilter()
   
cutSurfaceRepairedTriangles.SetInputConnection(cutSurfaceRepaired.GetOutputPort())
    cutSurfaceRepairedTriangles.Update()
    
    return cutSurfaceRepairedTriangles

I've tested the code in python on different datasets (~100 boolean
operations) and my code never crashed. 

Looking forward to the release,
Norman

I assume this is failing even with the crash fix recently merged to master?

Do you have data sets you can share to reproduce the problem?

Thanks,
Cory

Hmm, weren't we moving examples into VTK itself? Or were we moving them
out?

We are keeping the wiki examples out of VTK. When I get a chance, I'll
make them an External Module.

I'ld like to move the ${VTKSRC}/Examples onto the wiki (or External module
if you like). Having 2 example sets is a point of confusion so we should
consolidate to the one with better web searchable infrastructure.

I'ld also like to change the VTK Wiki examples submitters to have them push
results to the  "WikiExamples" build group on VTK's cdash. Then developers
will realize when they break examples.

Sadly, I can't seem to find the time to do either just now.

Dave, over the winter I'll work on submitting the wiki examples to the vtk
dashboard.

Hey Cory,

I have some troubles combining vtkImageData with the vtkTable. I tried 
the following:

vtkSmartPointer<vtkImageThreshold> threshold1 =
         vtkSmartPointer<vtkImageThreshold>::New();
threshold1->SetInputData(con->GetOutput());
threshold1->ThresholdBetween(lower, upper);
threshold1->ReplaceInOn();
threshold1->SetInValue(CLASS_1_VALUE);
threshold1->Update();

unsigned int numPoints = threshold1->GetOutput()->GetNumberOfPoints();
     for (unsigned int dimension = 0; dimension < 3; dimension++)
     {
         std::stringstream colName;
         colName << "dimension" << dimension;
         VTK_PTR_CREATE(vtkIntArray, values);
         values->SetNumberOfComponents(1);
         values->SetName(colName.str().c_str());
         values->SetNumberOfTuples(numPoints);

         for(unsigned int pt = 0; pt < numPoints; pt++)
         {
             double point[3];
             double originalPoint[3];
             threshold1->GetOutput()->GetPoint(pt, point);
             data->GetPoint(pt, originalPoint);
             values->SetValue(pt, originalPoint[dimension]);
             bool lg2 = originalPoint[dimension] > lower && 
originalPoint[dimension] < upper;
             if (lg2)
             {
                 cout << "original between, so " << (unsigned 
int)point[dimension] << endl;
             }
             else
             {
                 cout << "mh " << originalPoint[dimension] << [...] << endl;
             }
         }
         table->AddColumn(values);
     }

Unfortunately, the outputs I get are pretty useless in my scenario:

mh 279 lower 970 upper 990

mh 280 lower 970 upper 990

mh 281 lower 970 upper 990

mh 282 lower 970 upper 990

mh 283 lower 970 upper 990

mh 284 lower 970 upper 990

mh 285 lower 970 upper 990

mh 286 lower 970 upper 990

mh 287 lower 970 upper 990

mh 288 lower 970 upper 990

mh 289 lower 970 upper 990

mh 290 lower 970 upper 990

mh 291 lower 970 upper 990

mh 292 lower 970 upper 990

mh 293 lower 970 upper 990

mh 294 lower 970 upper 990

mh 295 lower 970 upper 990

mh 296 lower 970 upper 990

mh 297 lower 970 upper 990

mh 298 lower 970 upper 990

mh 299 lower 970 upper 990

mh 300 lower 970 upper 990

mh 301 lower 970 upper 990

mh 302 lower 970 upper 990


These are just my dimensions, so it repeats the numbers 0 to 519.

VTK_PTR_CREATE(type,name) is defined as vtkSmartPointer<type> name = 
vtkSmartPointer<type>::New();

So obviously, this approach is wrong. The examples, given in the wiki, 
correspond to given data points, not image data. Can you help me? I 
think this class would be great as far as I can tell by using vtkChartXY 
for plotting a histogram.

Greetings
Imre

Hi Cory,

Yes, I forgot to mention this. The problem also occurred for all the version
I've tested: 5.10.1, 6.2.0, 6.3.0 and the one with the recent fix.

Because the data I'm testing with is not supposed to be public I'll send it
to you as PM.

Your support on this is much appreciated.

Norman

Message-ID: <4760d515-44d5-4d74-85e4-55165e436e72@me.com>


Here's some code that shows the issue I'm trying to resolve...


I have some sampled 3D points that are essentially a tube.?(I cut out a lot of data, show the example doesn't look like a tube, but this shows the issue)?

I can build the surface of the tube but, the two ends of the tube want to join together. In the program below, you can see the wide strips that go straight back from one end to the other.

How do I disconnect the strips at the ends from each other?

Thanks,

Rick

Subject: [vtkusers] How to extract nodesets and sidesets for Exodus data
Message-ID: <CAGWYgTnYkes5zHWSPhPHKv=X0WLG-rBUT0K38BJBuwiPULDBzQ@mail.gmail.com>

I am creating a visualization tool for Exodus data capable of displaying
any combination of nodeset, sideset, and subdomain information from an
ExodusII file. I would like to be able to have a single reader object and
multiple renderers for showing the nodesets, sidesets, and/or subdomains.

However, I am unable to figure out how to enable all of the above in
vtkExodusIIReader but limit what is shown in the renderer.

I have attached a script (OSX with VTK6.3) that I would like to have
display the nodesets on the left-side of the screen and the subdomains on
the right, but I am unable to get the desired result.

I would appreciate any help that could be provided.

Thanks,
Andrew

Subject: [vtkusers] How to set the vtkMatrix4x4 in function SetResliceAxes()
	of vtkImageReslice
Message-ID: <tencent_5E9B4F21350A27096460972C@qq.com>

Hi,


In Class vtkImageReslice , virtual void vtkImageReslice::SetResliceAxes (vtkMatrix4x4 *)
Why Matrix:
1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
0, 0, 0, 1 

can get a slice that parallel to the XY plane?


What the Matrix means in mathematics?


Where can I get the detailed description?


Thanks,
Yihui Cao

Hey,

I tried this:

int *numPoints = threshold1->GetOutput()->GetDimensions();
     VTK_PTR_CREATE(vtkIntArray, axisX);
     axisX->SetName("Axis X");
     VTK_PTR_CREATE(vtkIntArray, axisY);
     axisX->SetName("Axis Y");
     VTK_PTR_CREATE(vtkIntArray, values);
     axisX->SetName("Values");
     table->AddColumn(axisX);
     table->AddColumn(axisY);
     table->AddColumn(values);
     table->SetNumberOfRows(data->GetNumberOfPoints()); //520*520*47
     int row = 0;
     cout << "numoints " << data->GetNumberOfPoints() << endl;
     // numoints 12708800

     for (unsigned int x = 0; x < numPoints[0]; x++)
     {
         table->SetValue(row,0,x);
         for(unsigned int y = 0; y < numPoints[1]; y++)
         {
             table->SetValue(row,1,y);
             for(unsigned int z = 0; z < numPoints[2]; z++)
             {
                 unsigned int val = *static_cast<unsigned 
int*>(threshold1->GetOutput()->GetScalarPointer(x,y,z));
                 table->SetValue(row++,2,val);
             }
         }
     }
     VTK_PTR_CREATE(vtkChartXYZ, chart);
     VTK_PTR_CREATE(vtkPlotSurface, plot);
     VTK_PTR_CREATE(vtkContextView, view);

     view->GetRenderer()->SetBackground(1, 1, 1);
     view->GetScene()->AddItem(chart);
     plot->SetInputData(table);

imgDisplay->GetRenderWindow()->AddRenderer(view->GetRenderer());
     view->GetRenderWindow()->SetMultiSamples(0);
     view->SetInteractor(imgDisplay->GetInteractor());
     imgDisplay->SetRenderWindow(view->GetRenderWindow());
     // Visualize the histogram

     // Initialize the event loop and then start it
     imgDisplay->show();
     view->GetInteractor()->Initialize();
     view->GetInteractor()->Start();

but Qt throws exceptions. I think I stick with the other solution, 
except you guys have some solutions for me, which would be great 
(imgDisplay is a QVTKWidget, this works fine with vtkChartXY). The error 
message:

Qt has caught an exception thrown from an event handler. Throwing

exceptions from an event handler is not supported in Qt. You must

reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'std::bad_alloc'

what(): std::bad_alloc

The class documentation describes the matrix as representing transformations in homogenous (x, y, z, w) coordinates:

An example usage:

Hi,

In Class vtkImageReslice , virtual void vtkImageReslice::SetResliceAxes (vtkMatrix4x4 *)
Why Matrix:
1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
0, 0, 0, 1
can get a slice that parallel to the XY plane?

What the Matrix means in mathematics?

Where can I get the detailed description?

Thanks,
Yihui Cao

Serge.

You are correct.

We removed that to clean house in preparation for the parallel extent
handling improvements. The priority streaming feature it was part of was
largely unused in VTK and ParaView and we knew of no other users.

If the use-case you are seeing was in an Algorithm that emitted it you are
fine with simply removing it. If you had something that consumed it, then
there would be more work as we don't have a direct replacement for this in
the works.

Hi Aashish,

I applied the patch to the latest VTK (from GIT) and rebuilt it.
An error occurred when I run the test program you gave me without gradient opacity.
Please find the attached file.
I am not sure why?

Thank you,

Kenji

Hi Aashish,

Adding gradient opacity to the test sample causes the same error I have seen in my application.
Please refer to the attached file.
So my application works with IndependentComponents On after removing gradient opacity.

Thanks Kenji for trying out. Its not clear in the log why the build shader code crashed.
Also, I realized that you using Java bindings. Would it be possible to re-create this issue
with a small sample code and you send it to me? We do have two component and 4 component
test (dependent and independent). Please have a look here: https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTwoComponentsIndependent.cxx

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.

I don't remember vtkSmartVolumeMapper has this logic, I will have a look. In the old GPU raycast mapper, there was some issue with independent components so may be that is the reason that smart volume mapper switched to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can directly use GPUVolume RayCastMapper

My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

?For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function.?

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Hi Aashish,

I tried, but both my application and the test program doesn?t work with gradient opacity.
The display window were black.
There is no apparent error?

Thank you,

Kenji

Hi Aashish,

Adding gradient opacity to the test sample causes the same error I have seen in my application.
Please refer to the attached file.
So my application works with IndependentComponents On after removing gradient opacity.

Thank you very much.
I will try to run the test example and see what happens.
If the test is ok, I will try to reproduce the problem with simpler code.

Thanks Kenji for trying out. Its not clear in the log why the build shader code crashed.
Also, I realized that you using Java bindings. Would it be possible to re-create this issue
with a small sample code and you send it to me? We do have two component and 4 component
test (dependent and independent). Please have a look here: https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTwoComponentsIndependent.cxx

and

I tried with vtkGPUVolumeRayCastMapper.
An error occurs without setting IndependentComponentsOff.
It seems  the error occurs in vtkOpenGLGPUVolumeRayCastMapper::BuildShader (See the attached file).

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.

I don't remember vtkSmartVolumeMapper has this logic, I will have a look. In the old GPU raycast mapper, there was some issue with independent components so may be that is the reason that smart volume mapper switched to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can directly use GPUVolume RayCastMapper

My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

?For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function.?

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Make sure that your gradient opacity function is set correctly (or as
expected). I believe you are going from 0.0 - 0.5. Can you change it to 0.2
- 0.5 and see if something shows up?

Thanks,

Thank for the advice.
Now I can see volume rendering in both my application and test program with gradient option.
When I run, the console output program source code in the attached file.
Is this because I am using latest VTK?

Thank you,

Kenji

Make sure that your gradient opacity function is set correctly (or as expected). I believe you are going from 0.0 - 0.5. Can you change it to 0.2 - 0.5 and see if something shows up?

Thanks,

Hi Aashish,

Adding gradient opacity to the test sample causes the same error I have seen in my application.
Please refer to the attached file.
So my application works with IndependentComponents On after removing gradient opacity.

Thanks Kenji for trying out. Its not clear in the log why the build shader code crashed.
Also, I realized that you using Java bindings. Would it be possible to re-create this issue
with a small sample code and you send it to me? We do have two component and 4 component
test (dependent and independent). Please have a look here: https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTwoComponentsIndependent.cxx

and

I tried with vtkGPUVolumeRayCastMapper.
An error occurs without setting IndependentComponentsOff.
It seems  the error occurs in vtkOpenGLGPUVolumeRayCastMapper::BuildShader (See the attached file).

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.

I don't remember vtkSmartVolumeMapper has this logic, I will have a look. In the old GPU raycast mapper, there was some issue with independent components so may be that is the reason that smart volume mapper switched to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can directly use GPUVolume RayCastMapper

My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

?For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function.?

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Hi Kenji,

That's just my patch in case you had to send me what shader we were
generating. You can
ignore this as in my branch to VTK, I will remove it. Make sure that your
gradients are matching
with gradient opacity values or else you would not see anything or will see
unexpected color
and opacity.

Are you using installed VTK libraries? Also, make sure you link with
vtkRenderingVolumeOpenGL.

I was wondering about that. When using SmartVolumeMapper, did you include
its header in the mm file? If you are linking with vtkRenderingCore and
vtkRenderingVolumeOpenGL and vtkRenderingVolume then it seems strange that
you are running into this issue.

Subject: [vtkusers] Turn off Observers "MouseMoveEvent" in
	vtkInteractorStyleImage
Message-ID: <tencent_233F9ECB07CDDF8B5F0BC614@qq.com>

Hi,

When I show an image used vtkInteractorStyleImage, left button down and move, the ColorLevel of image will changing. I want to turn off the observer of "MouseMoveEvent" and write the follow code. But it do not work. So anyone can tell me how to turn off the observer or turn off this function.


cpp code:
	vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
		vtkSmartPointer<vtkRenderWindowInteractor>::New();
	vtkSmartPointer<vtkInteractorStyleImage> imagestyle =
		vtkSmartPointer<vtkInteractorStyleImage>::New();


	imagestyle->RemoveObservers(vtkCommand::MouseMoveEvent);
	//imagestyle->RemoveAllObservers();


	renderWindowInteractor->SetInteractorStyle(imagestyle);
	renderWindowInteractor->SetRenderWindow(renderWindow);
	renderWindowInteractor->Initialize();
	renderWindowInteractor->Start();


Thanks,
Yihui Cao

Maybe try adding


vtkObjectFactory::RegisterFactory(vtkRenderingVolumeOpenGL2ObjectFactory::New());

early on and make sure you are building vtk with the OpenGL ES version 3.0
versus 2.0

Sorry I was assuming you were on iOS based on prior emails. If on x86 etc
then ignore what I said.

No sir you are right, 

just added this line and it works fine,

    vtkObjectFactory::RegisterFactory(vtkRenderingOpenGL2ObjectFactory::New());
    
    vtkObjectFactory::RegisterFactory(vtkRenderingVolumeOpenGL2ObjectFactory::New());

Thanks a lot.

That won't work. There aren't any observers registered with the interactor
style. The style does register observers with the interactor which you
theoretically selectively remove, but I wouldn't recommend that.

Instead, you can subclass vtkInteractorStyleImage and override the
OnMouseMove() member function to avoid the change in color level.

Thanks,
Cory

Thanks Ken. I see that in the example code you have added a call to
RegisterFactory on OpenGL2. I am wondering why it is needed to make a
explicit call to it?

I do not know why it is required for me on iOS but it seemed that at least
some times I do need it. Maybe an objective C setting on my Xcode projects
or something with the cross compiled framework initialization. Not sure.

Thanks

Hello,

when register with ?vtkRenderingVolumeOpenGL2ObjectFactory? only, an error appears, 

Error: no override found for 'vtkRenderer?.

and when register ?vtkRenderingOpenGL2ObjectFactory? only this error appears, 

Error: no override found for 'vtkRayCastImageDisplayHelper?.

when using any of volume mapper techniques i need to register the two of them so it works fine.

except ?vtkOpenGLGPUVolumeRayCastMapper? works fine with ?vtkRenderingOpenGL2ObjectFactory? only

yes it all makes sense. * vtkRenderer *is defined in vtkRenderingOpenGL and
Volume classes are contained in the other module. So yes, you would need
both.

VTK seems to use the 'Legacy NetCDF-3 C++' while Arch provides 'NetCDF-4
C++', using the name from
http://www.unidata.ucar.edu/downloads/netcdf/index.jsp, I think that's
why the build with system NetCDF is failing.

Using the attached patch makes permits to build with system HDF5 and
bundled NetCDF, but I do not see why it's working.

Hrm, OK. Well, NetCDF and HDF5 are next on my list of "update VTK's
third party packages" anyways. Not sure when I'll get the time though.

I guess it makes sure that the right HDF5 is found? It looks strange,
but I didn't look at it in-depth either.

If your goal is simply not to have any mouse activity do anything in
the window, you could just use an instance of vtkInteractorStyle
itself instead of vtkInteractorStyleImage.

The base class vtkInteractorStyle does not have any mouse handling
code in it, but it does implement the standard VTK keyboard shortcuts.


HTH,

Subject: [vtkusers] Set light Intensity
Message-ID: <CAOnPkweECWmhLk57d+ZM+GhXsWPtQMoEP2q5z4xDwjYO6oxt6A@mail.gmail.com>

Hi,
I would like to know, how to set lighting Intensity on a scene.
I already look at those examples:
http://www.vtk.org/Wiki/VTK/Examples/Cxx#Lighting

The first example: I dont need a new shadow.
The second example: I dont think that i need a new light to contrabalance
the first light.
The third example: I tried but the error: Is not a spotlight happens.

And, i'm working with Vtk + Qt, and i dont find any solutions on the web.

I tried this:

 auto  col = vtkSmartPointer<vtkLightCollection>::New();

    col = renderer->GetLights();

    light = col->GetNextItem();

    light->SetIntensity(10);


But the program crashed.
What do i do?
Please, help me.

The header unistd.h is posix standard and comes with every Xcode SDK.  Try
compiling the following trivial program.  If it doesn't compile, then there
must be something awry with your Xcode installation:

#include <unistd.h>
int main()
{
  return 0;
}

'gcc tmp.cpp' created an 'a.out' file, and I have been able to compile
other things, so I guess my Xcode installation is fine.  What do you
recommend I try next?

Cheers,

You can try setting the SDK info in the CMakeCache.txt:

CMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.11
CMAKE_OSX_ARCHITECTURES:STRING=x86_64
CMAKE_OSX_SYSROOT:STRING=macosx10.11

I recommend deleting your entire build directory, creating a new
CMakeCache.txt that has only these three lines, and then re-running cmake.

Actually I might have misunderstood your issue.  Did you build VTK 6
yourself, or did you download a binary package?  In either case, the three
cmake variables that I mentioned above should be set the same in your own
project as they are in the VTK that you are building against.

I built VTK 6 through the Anaconda Python distribution ("conda install vtk"
installed 6.3).

I placed the three lines you recommended in the top-level CMakeLists.txt
file in my library:
SET(CMAKE_OSX_DEPLOYMENT_TARGET "10.11")
SET(CMAKE_OSX_ARCHITECTURES "x86_64")
SET(CMAKE_OSX_SYSROOT "macosx10.11")

This enabled the make command to compile farther than I have been able to
get so far.  However, it requires someone to explicitly specify which
version of MacOSX, which I was hoping to avoid.  Previously, I was using:

#https://forums.developer.apple.com/thread/17334
SET(CMAKE_OSX_DEPLOYMENT_TARGET "")
SET(CMAKE_OSX_SYSROOT /)

or:

# https://cmake.org/Bug/view.php?id=14695
SET(MACOSX_DEPLOYMENT_TARGET
${DARWIN_MAJOR_SDK_VERSION}.${DARWIN_MINOR_SDK_VERSION})
SET(CMAKE_CXX_FLAGS "--sysroot ${CMAKE_OSX_SYSROOT} ${CMAKE_CXX_FLAGS}")



Cheers,
@rno

I forgot to mention that the other reason for not explicitly setting the
version of OSX in the CMakeLists.txt file is because when I do set it
appropriately (as you suggested), compilation inexplicably raises the
following error, suggesting that outdated SDKs are required:

make[2]: *** No rule to make target
`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/AGL.framework',
needed by `travel_depth/TravelDepthMain'.  Stop.

Cheers,
@rno

Ah, so you're building a binary package to share with others. I strongly
advise against using these:

SET(CMAKE_OSX_DEPLOYMENT_TARGET "")
SET(CMAKE_OSX_SYSROOT /)

The resulting binary will only work with your own version of OS X or
later.  Your best bet is to name a reasonably old deployment target (e.g.
10.7) and SDK (e.g. 10.9).

CMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.7
CMAKE_OSX_SYSROOT:STRING=macosx10.9

These will provide a binary package that will work on 10.7 or later.

What is the minimum supported OS X that the anaconda VTK supports?
Ideally, you should use that version as your deployment target.

As for AGL, it might be missing from some SDKs because it is obsolete
(modern programs should not be using it).  However, it is in my 10.9 SDK,
so it will probably also be in yours.

Thank you for clarifying this for me!!

When I set the SDK to 10.9:
SET(CMAKE_OSX_SYSROOT "macosx10.9")

I get the error:
clang: warning: no such sysroot directory: 'macosx10.9'

I don't get this error when I set the SDK to 'macosx10.11', but would this
setting place an unreasonable demand on the target architecture?

Cheers,
@rno

You could try this :

  vtkSmartPointer<vtkLightCollection>  col =
vtkSmartPointer<vtkLightCollection>::New();

    col = ren->GetLights();
        int i=col->GetNumberOfItems();  // to be sure there is at list one
light
    light = (vtkLight*)col->GetItemAsObject(0);
    light->SetIntensity(10);

Subject: [vtkusers] Problem after having updating vtk (5.10 to 6.2)
Message-ID: <1449831658144-5735483.post@n5.nabble.com>

Hi ! And sorry for my English :)
I am working on visual studio 2008 and WIndows 7 in C++
I just changed of Vtk version 5.10 to 6.2, and my program runs as it is
supposed to do but one thing, I have this kind of error messages in a
vtkOutputWindow :

ERROR: In .\vtkOpenGLRenderer.cxx, line 126
vtkOpenGLRenderer (03A4D058): failed ater ClearLights 16 OpenGL errors

vtkOpenGLRenderer (03A4D058): failed after DeviceRender 16 OpenGL errors
detected
  0 : (1282) Invalid operation
....

I really dont know where it comes from, I added these lines to the beginning
of my project (as I saw on the internet) to fix the change of version but
there is still those messages :
#include <vtkVersion.h>
 #include <vtkAutoInit.h>
 VTK_MODULE_INIT(vtkRenderingOpenGL);
 #define vtkRenderingCore_AUTOINIT
4(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingFreeTypeOpenGL,vtkRenderingOpenGL)
#define vtkRenderingVolume_AUTOINIT 1(vtkRenderingVolumeOpenGL)

Does someone have an idea?
Thanks for reading,

Am?lie

Hello,


I need to display dynamic grids as it appears with vtkChartXY. But I need to display grids into vtkRenderer object and not context2d. Is this possible?


Thanks

If you are using the OpenGL2 backend with 6.2 then those are expected.  I
believe they have been cleaned up (mostly?) in more recent VTK builds.

Thanks

Hi Arno,

Using the macosx10.11 SDK is fine as long as it allows you to set this
desired deployment target.  So if you are able to compile with the
following settings, then the result should run on OS X 10.7:

CMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.7
CMAKE_OSX_SYSROOT:STRING=macosx10.11

I'm not sure how far back you can set the deployment target with this SDK,
but if the 10.7 target doesn't compile, you can try 10.8 or 10.9.

If if gives errors for the AGL.framework, then make sure that your code has
no calls to Carbon APIs.

 - David

This should be the full path to the sysroot:

    /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk

Bill, the LightCollection dont have this method. The equivalence is
NewInstance?
I'm trying this:

 GetRenderWindow()->AddRenderer(renderer);

    renderer->SetBackground(0.576,0.749,0.874);

    renderer->CreateLight();

    lightCol->NewInstance();

    lightCol = renderer->GetLights();

    int i = lightCol->GetNumberOfItems();

    if(i>0){

        light = (vtkLight*)lightCol->GetItemAsObject(0);

        light->SetIntensity(10);

    }


But the view dont change.
What do I want, is to improve the vizualiation of the 3d models that I load.
>From this:
http://pt-br.tinypic.com/r/2aj6zh2/9

To something like this:
http://centrumdruku3d.pl/wp-content/uploads/2014/12/RepetierServer2.png

And i think that correcting the lights, will be the first step...

See ya

Why?  CMake, only recently perhaps, accepts strings like "macosx10.11" as David wrote.  Which is really nice, because hardcoding paths is fragile of course.

Subject: [vtkusers] Could not find any working toolchain in the NDK. Android
 NDK is broken
Message-ID: <1449848568821-5735493.post@n5.nabble.com>

So I just recently switched to El Capitan on my mac and I'm trying to get VTK
for android to work again (I did a clean install). I downloaded android SDK
and NDK, added them to the PATH, used Cmake to configure and generate with
no error but now when I Make the project I get this error:

CMake Error at CMake/android.toolchain.cmake:631 (message):
  Could not find any working toolchain in the NDK.  Probably your Android
NDK
  is broken.
Call Stack (most recent call first):
 
/usr/local/Cellar/cmake/3.4.1/share/cmake/Modules/CMakeDetermineSystem.cmake:98
(include)
  CMakeLists.txt:29 (project)

So I get that the android-toolchain could not be found but I kind of fail to
understand why. Especially since my configuration on my previous OS was
really similar to what I have now. I am using the last version of vtk
available on git. Could that be an error related to El Capitan only or did I
miss something obvious?

Thanks in advance for the help.

As usual, when I post here, I have created a SO post with more details  Here

Hmm, that is new behavior to me. The paraview superbuild needs to
smarten up then (it uses the value in --sysroot= flags it passes to
subprojects).

Probably have to update your VTK (although last night was a wreck so maybe
not the current master) . My macbook is on el capitan and it is working ala

It translates points outward from the normals defined by a point normal
array. If that's not the direction you wan, you can scale by a negative
number.

See [1] for more details.

Got it working.
Reset my whole PATH and not it works so I guess it was just a PATH issue in
the end.
Thanks anyway.

I tried again, and am still getting the AGL.framework error even when I set
to 10.9 and the SDK to 10.11 (see:
https://github.com/nipy/mindboggle/blob/master/surface_cpp_tools/CMakeLists.txt
):

Could you please tell me how to ensure that there are no calls to Carbon
APIs?

By the way, I am tracking this as an issue on Github:
https://github.com/nipy/mindboggle/issues/69

Hi all,

FWIW, I just upgraded my Xcode to 7.2 and projects which had previously been configured by CMake suddenly started failing with this error (unistd.h file not found) because the MacOSX10.9 SDK directory was removed: only the 10.11 SDK is provided with Xcode 7.2. You can still set the deployment target to 10.9 but I have not tried anything earlier.

	David

Hi Arno,

I think that I've found out where the AGL link is coming from.  It isn't
via Carbon, it looks like it was linked directly into the VTK that you're
using.  And it looks like a bug within CMake itself.

CMake has a module called FindOpenGL.cmake that VTK uses to find OpenGL.
It looks for both the OpenGL.framework and for the obsolete AGL.framework
(which is only for Carbon, and is deprecated by Apple).  If it finds both
(e.g. with an older SDK and XCode 6 or earlier), then it uses both, even
though AGL.framework is really not needed for any modern software.

This means that a VTK that is built with (for example) Xcode 6 and its SDKs
becomes linked to AGL, because AGL.framework is present in those older
SDKs.  It's a private link, though, so I'm surprised that it would cause
the error.  But you are building with Xcode 7 and you are seeing an
error... that much is indisputable.

I suggest that you enable verbose error reporting so that you can see
exactly what is being linked when the error occurs:

export VERBOSE=1
make
...

Use "unset VERBOSE" to turn off the verbosity.

 - David

Hi Kenji,

I created a merge request and added a test for two component (independent)
with gradient opacity here (
https://gitlab.kitware.com/vtk/vtk/merge_requests/1007/diffs). After
sending you the patch I looked at your opacity values closely and was
trying to find this tricky bug as I was not happy with the image the code
was generating. I fixed all of the remaining issues and with you original
code, I believe I am getting the correct rendering.  Thank you so much for
reporting this bug as not only I fixed the bug but hopefully increase the
code coverage as well.

Thanks,
Aashish

Message-ID: <CAK6Z60eVzSzK5dPxGgZ_nyn_+wHfQZbpuZH2EYFa-OCd0dtSmQ@mail.gmail.com>

Hi everyone,

I've been using the `vtkUnstructuredGridReader` and the
`vtkXMLUnstructuredGridReader` for a while now to read VTK/VTU meshes, e.g.,
```
        reader = vtk.vtkUnstructuredGridReader()
        reader.SetFileName(filename)
        reader.Update()
        vtk_mesh = reader.GetOutput()
```
and then
```
    points = vtk.util.numpy_support.vtk_to_numpy(
            vtk_mesh.GetPoints().GetData()
            )
```
etc. From the documentation, it seemed easy enough to phase in the
`vtkXdmfReader`. However,
```
AttributeError: 'vtkIOXdmf2Python.vtkXdmfReader' object has no attribute
'GetOutput'
```
Any hints on how to use the `vtkXdmfReader`?

Cheers,
Nico

The reader will produce different types of data dependent on the file it
reads, so you need to use GetOutputDataObject instead and cast
appropriately.

Thanks for the reply!
`GetOutputDataObject` takes a `port` as input argument, and putting `0`
seems to work, but I don't actually know what I'm doing. Any more hints
here?

Some vtkAlgorithms produce more than one thing and you use the port to
specify which thing you want. An example being vtkGaussianCube reader
(molecule = port0, field = port 1).

This reader does not so 0 is what you want.

Hi Aashish,

We will try the latest whenever your fix is available.
Thank you so much for your advice.

Hi Kenji,

I created a merge request and added a test for two component (independent) with gradient opacity here (https://gitlab.kitware.com/vtk/vtk/merge_requests/1007/diffs). After sending you the patch I looked at your opacity values closely and was trying to find this tricky bug as I was not happy with the image the code was generating. I fixed all of the remaining issues and with you original code, I believe I am getting the correct rendering.  Thank you so much for reporting this bug as not only I fixed the bug but hopefully increase the code coverage as well.

Thanks,
Aashish

Hi Kenji,

That's just my patch in case you had to send me what shader we were generating. You can
ignore this as in my branch to VTK, I will remove it. Make sure that your gradients are matching
with gradient opacity values or else you would not see anything or will see unexpected color
and opacity.

Now I can see volume rendering in both my application and test program with gradient option.
When I run, the console output program source code in the attached file.
Is this because I am using latest VTK?

Make sure that your gradient opacity function is set correctly (or as expected). I believe you are going from 0.0 - 0.5. Can you change it to 0.2 - 0.5 and see if something shows up?

Thanks,

Hi Aashish,

Adding gradient opacity to the test sample causes the same error I have seen in my application.
Please refer to the attached file.
So my application works with IndependentComponents On after removing gradient opacity.

Aashish,

Thank you very much.
I will try to run the test example and see what happens.
If the test is ok, I will try to reproduce the problem with simpler code.

Thanks Kenji for trying out. Its not clear in the log why the build shader code crashed.
Also, I realized that you using Java bindings. Would it be possible to re-create this issue
with a small sample code and you send it to me? We do have two component and 4 component
test (dependent and independent). Please have a look here: https://github.com/Kitware/VTK/blob/master/Rendering/Volume/Testing/Cxx/TestGPURayCastTwoComponentsIndependent.cxx

and

Thanks,

Hi Aashish,

Thank you.
I tried with vtkGPUVolumeRayCastMapper.
An error occurs without setting IndependentComponentsOff.
It seems  the error occurs in vtkOpenGLGPUVolumeRayCastMapper::BuildShader (See the attached file).

Hello,

I have 3D cardiac MRI data (magnitude data and velocity data), and would like to display the volume rendering of the two data.
I create vtkVolume with two components  (first one is velocity data and second one is magnitude data) and use vtkSmartVolumeMapper.
When I set IndependentComponentsOn to the volume property, I can see what I want (refer to the first figure).
But this setting disables GPU rendering and it is slow.

I don't remember vtkSmartVolumeMapper has this logic, I will have a look. In the old GPU raycast mapper, there was some issue with independent components so may be that is the reason that smart volume mapper switched to fixed point ray cast.

Is there a particular reason you are using vtkSmartVolumeMapper?  You can directly use GPUVolume RayCastMapper

My understanding is that I have to use IndependentComponentsOff to make the mapper use GPU rendering.
When I set IndependentComponentsOff, only one color transfer function, and only one scalar opacity function to the volume property,
the magnitude data (the second component) is also color-coded (refer to the second figure).
I thought this contradicts the method comments of IndependentComponentsOn/ IndependentComponentsOff.

?For 2 component data, the first is passed through the first color transfer function and the second component is passed through the first opacity transfer function.?

Am I missing something?
Can I make the volume rendering look the same as using two components?

Thank you,

BTY, I use v6.3.0, OpenGL2.

Subject: [vtkusers] Using ExternalVTKWidget with an external OpenGL context
	(OpenSG)
Message-ID: <CAGenMyJanK3E+kXKpkVN4bwJQNjc-fCAaAokeVt_0bJGJHgbAQ@mail.gmail.com>

Dear All,
I am trying to draw some VTK stuff inside a pre-existing OpenGL context;
this context has been created with a library called OpenSG (not to be
confused with OpenSceneGraph).

After some trial-and-error development, I managed to adapt a OpenSG example
and integrate some VTK rendering. In the initialization phase I:
- create an OpenSG GLUT window and put a torus inside the OpenSG scene,
- create a VTK ExternalVTKWidget and related window/renderer, and put a
cube inside the VTK scene.
In the GLUT main loop, I:
- activate the OpenSG window,
- draw the OpenSG torus,
- setup some GL stuff for camera and lights (why?!?),
- draw the VTK cube,
- swap buffers and deactivate the OpenSG window.

Now, my questions are essentially two:
1) Why do I need to write the OpenGL/glu code for the camera and the
lights? It seems to me that OpenSG correctly calls the OpenGL state machine
and sets up the camera and lights, but, when it comes to VTK, the internal
camera and lights settings are not used (for example, if I set the camera
near and far plane in the vtkRenderer it is ignored, to get everything work
I have to call the gluPerspective() on each frame). The same for the
Modelview tranform.
2) When I quit the application, a VTK window opens and prompts me for some
OpenGL errors: "
Generic Warning: In
..\..\..\VTK-6.3.0\Rendering\OpenGL\vtkOpenGLDisplayListPainter.cxx, line 52
failed after ReleaseAllLists 16 OpenGL errors detected
  0 : (1282) Invalid operation

Currently , I am developing with Visual Studio 2010.
Any suggestion or hint will be highly appreciated!

Christian

Could anyone help me?

Thanks.

Subject: [vtkusers] Error in installing vtk5.10
Message-ID: <1864639965.192473.1450108458273.JavaMail.zimbra@psu.edu>

Hi,

I am trying to install the vtk5.10.1 on Mac Yosemite. I have followed the instructions on the website, installed Cmake and Qt, and copied all the source and data files in the same path. I have configured the cake files as it was mentioned in the instructions (http://www.vtk.org/Wiki/VTK/Building/MacOSX) and ran the "make" command. I received the an error regarding duplicated symbol during the make process, and I have included the details of the error in the attachment. I would be very thankful if you could help me on this. Please do not hesitate to contact me if you need any further information./

With best regards,
Kasra

Subject: [vtkusers] VTK 6.3 with Qt Creator on OSX
Message-ID: <1450175895075-5735524.post@n5.nabble.com>

Hi all,

Having updated to 6.3, I modified my Qt Creator .pro file accordingly:

------------------------------------ BEFORE
------------------------------------

INCLUDEPATH += /Applications/VTK/6.2/Install/include/vtk-6.2

LIBS += -L/Applications/VTK/6.2/Install/lib/ \
    -lvtkChartsCore-6.2 \
    -lvtkCommonColor-6.2 \
    -lvtkCommonComputationalGeometry-6.2 \
    -lvtkCommonCore-6.2 \
      and so on...

------------------------------------- NOW
--------------------------------------

INCLUDEPATH += /Applications/VTK/6.3/Install/include/vtk-6.3
#inclusion of second includepath is just for vtkDICOM
INCLUDEPATH += /Applications/VTK/6.3/Install/include/    

LIBS += -L/Applications/VTK/6.3/Install/lib/ \
     -lvtkChartsCore-6.3 \
     -lvtkCommonColor-6.3 \
     -lvtkCommonComputationalGeometry-6.3 \
     -lvtkCommonCore-6.3 \
      and so on...

However, I always get the error: 
  dyld: Library not loaded: libvtkChartsCore-6.3.1.dylib
  Referenced from: /Users/CRCT_Richard/Desktop/d/build/d
  Reason: image not found

It strikes me as weird, because, since qmake has managed to determine that
lvtkChartsCore-6.3 corresponds to libvtkChartsCore-6.3.1.dylib, it must have
found the file. So I don't understand how it can say the image was not
found. 

I have little (no) understanding of dynamic libraries, so maybe the error is
saying something else. Can anyone shed any light on to what's going wrong?

I'm using OSX El Capitan if that changes anything.

Cheers,
Richard

Hi Kevin!
Please, always send your messages to vtkusers list, that increases your
chances of getting help.
Go to
http://www.vtk.org/Wiki/VTK/Examples

and use one of the writer examples.
On vtk site you should be able to find information how to use vtk library/

You will meed CMake, also from Kitware.

Can you print in your Cmake the value of /VTK_DIR/? Then check if
/VTKConfig.cmake/ is included in this directory?

>From  this post
<http://stackoverflow.com/questions/28467230/cmake-could-not-find-the-vtkconfig-cmake>  
it would appear that this can happen if it cannot find the config file for
VTK.

Hi Lonni,

VTK_DIR value is "VTK_DIR-NOTFOUND". After knowing it, I changed my
CMakeLists.txt file setting that variable to:

/set(VTK_DIR C:/dev/debug/lib/cmake/vtk-6.3)/

But I got the same error message. And yes /VTKConfig.cmake/ is included in
this directory.

Well usually it should not be round it VTK is built correctly. You did not
get any error message while building ?

I'm still learning to use CMake and VTK and I have never stumbled upon this
kind of error on any system (Ubuntu, Windows or Mac). I'm guessing that the
building went wrong somewhere and that's the only thing I c an think
of, but others (with a better knowledge) may think of something else.

No. There weren't errors on library compilation.

Maybe check VTK_FOUND ? I think that's the name of the macro. I'm on my
phone so can't check it out

Try changing your find VTK line to something like:
find_package(VTK 6.3 REQUIRED)

I'm guessing based on the error message where it is comparing 6.3 to the
version it thinks it should have (empty string).  The build system
migration guide [1] has the version specified in all of its examples...

HTH,
Shawn

Hi Shawn,

I changed find_package call to:

/find_package(VTK 6.3.0 REQUIRED NO_MODULE)/

I don't think so.  I guess that isn't the problem.  Are you configuring
your application as 32 bit against a 64 bit build of VTK? On Windows, which
generator you select in CMake determines whether your application is built
as 32 bit or 64 bit (for the Visual Studio generators anyway).  That could
be the problem.

Shawn

Guys,

I found the problem. I was building my application using only "cmake ..", so
not providing a Visual Studio generator. Thank you for your help!

Subject: [vtkusers] Trying to use vtkChartXY with Tcl
Message-ID: <567077AB.3090804@telefonica.net>

Dear list members,

I am interested to learn how to use the vtkChartXY class from Tcl scripts.

Since I couldn't find any Tcl examples, I am trying to translate 
existing python examples into Tcl.

My first efforts started with

http://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Charts/Core/Testing/Python/TestLinePlot.py

But I am having problems translating the following lines into Tcl:

line = chart.AddPlot(0)
line.SetInputData(table,0,2)

where chart was created with

vtkChartXY chart

Perhaps someone could help me to write the correct translation of this 
piece of code. I usually write programs in Lisp, and my knowledge of 
Python and Tcl is very limited.

I am working with version 6.3.

Thanks.

Hi Mario,

Tcl syntax a mixture of lisp and shell script.  The code will look like
this:

  set line [chart AddPlot 0]
  $line SetInputData table 0 2

Are you really sure that you want to use Tcl?  Many of the VTK classes
and methods that you can use with Python cannot be used from Tcl, so
it might not even be possible to convert that example into working Tcl
code.  You're welcome to try, though.

Now I see where I was wrong. I forgot the dollar symbol.

After writing:

[view GetRenderWindow] SetMultiSamples 0
[view GetRenderWindow] Render

where view was created by

vtkContextView view

I successfully get the expected plot.

The problem now is how to close the window with a mouse click. Any hints?

Yes, it is mandatory. We have the system Lisp -> Tcl -> Vtk for drawing 
3D scenes from Computer Algebra System Maxima:

http://riotorto.users.sourceforge.net/vtk/

Tcl is a dependency to be satisfied by Maxima, which is also used for 
other purposes.

I am trying to know how far we can go with Vtk for plotting 2D scenes, 
in order to extend the Maxima-Vtk interface.

Hi Mario,

The fact that you are using Tcl actually validates our continuing
support for Tcl, so in a way it is a good thing.

The best way to get a fully-functional VTK window with Tcl is to
use Tk.  Take a look at these two examples:

  Examples/GUI/Tcl/vtkTkRenderWidgetDemo.tcl
  Examples/GUI/Tcl/MaceTk.tcl

The MaceTk example provides a window close operation, using
this call to the window manager:

  wm protocol . WM_DELETE_WINDOW <callback function>

For more information, see the tk documentation, e.g.:
https://www.tcl.tk/man/tcl8.4/TkCmd/wm.htm

I know how to make a lookup table, but I dot know the right values that maps the scalar to RGB colors.

Subject: [vtkusers] trigger the execution of a vtkThreadedImageAlgorithm
 derived filter by calling Update()
Message-ID: <56714C41.3080500@kcl.ac.uk>

Hi all,

I am trying to write a multithreaded filter (vtkMeanSSD), derived from 
vtkThreadedImageAlgorithm, which will calculate the mean value of the 
difference between the intensities of two images (mean SSD).

What I want to achieve is that when I call Update() on my filter, the 
calculations occur and then I can retrieve the value by calling another 
method GetValue(). This is the snippet from my main file:


vtkSmartPointer<vtkMeanSSD> myfilter = vtkSmartPointer<vtkMeanSSD>::New();
myfilter->SetInput1Data(im1);
myfilter->SetInput2Data(im2);
myfilter->Update();
double val = myfilter->GetValue(); // value is 0, which is the default 
by construction

The problem I have is that when I call myfilter->Update() the filter is 
not executed. For some reason, it does execute if I plug it to a writer, 
for example


vtkSmartPointer<vtkMeanSSD> myfilter = vtkSmartPointer<vtkMeanSSD>::New();
myfilter->SetInput1Data(im1);
myfilter->SetInput2Data(im2);

  vtkSmartPointer<vtkNIFTIImageWriter> writer 
=vtkSmartPointer<vtkNIFTIImageWriter>::New();
writer->SetFileName("image_SSD.nii");
writer->SetInputConnection(myfilter->GetOutputPort());
writer->Write(); // This triggers the execution
double val = myfilter->GetValue(); // good value

Any advice how I can trigger the ThreadedRequestData method by calling 
update? Is there any other better way to achieve the functionality I want?

Thanks for your help. The full filter code is below.

Alberto

Hi vishal, 

Do you want to grab the 2d image and move it in constrained environment? If you have both in the renderer they will move together. Have you tried any example?

Between vtk 5 and vtk 6 the vtkRendering module was split into several
modules.  My first attempt at fixing this would be to replace it with
vtkRenderingCore and see if everything is still found.  Unless you are
doing something that extends the internals of the rendering code, you
shouldn't need to worry about using vtkRenderingOpenGL (this is where the
implementations live for vtkRenderingCore's abstract classes using the old
OpenGL1 backend, but requiring vtkRenderingCore should pull this in as
well).

It sounds like that example is broken when building against modern VTK.
Someone should fix it (I may get time later, if you want to, then go ahead).

HTH,
Shawn

Subject: [vtkusers] 64Bit memory problems
Message-ID: <E981F4B2-7B9E-480F-902B-2070091F0CD7@yahoo.de>

Hello,

I developed a tool to perform different types of Volume Rendering for Windows plattform. The code is written in C++. I use Visual Studio 2013 and VTK 6.1. So far everything is developed in 32bit and works very well. 
Now i want to switch to 64 bit. I rebuilt VTK with CMake for 64Bit and set VTK_USE_64BIT_IDS. I checked some of the VTK examples and it works. But not in my project. As soon as i create a VTK object it seems that the objects memory is corrupted. The program crashes afterwards with memory access errors. The non VTK parts runs stabil. It is strange. For testing i create a vtkRenderWindow right after entering the main entrypoint. When i check the member the Interactor for example points to 0x000000000000001. That looks like corrupted memory because the interactor member is set to zero in the constructor.
I don't know how to fix it, so maybe somebody had similar problems and knows what I have to do. Is there maybe a Project configuration which i should keep an eye of? I guess CMake is not the problem because the VTK examples with the same VTK dlls work perfect.

Please help me and thanks in advance
Andi

Subject: [vtkusers] vtkUnstructuredGridWriter only stores 6 digits?
Message-ID: <CAK6Z60f6KrmXVVPe-v9OCc81dFeGbaVX8YKxnDeT3ChOYyVZaA@mail.gmail.com>

Hi everyone,

with
```
import numpy
import vtk
from vtk.util import numpy_support

mesh = vtk.vtkUnstructuredGrid()

# add points to mesh
points = numpy.array([
    [0.123456789, 3.14159265, 0.0]
    ])
vtk_points = vtk.vtkPoints()
vtk_array = numpy_support.numpy_to_vtk(points)
vtk_points.SetData(vtk_array)
mesh.SetPoints(vtk_points)

# write to VTK
writer = vtk.vtkUnstructuredGridWriter()
writer.SetFileTypeToASCII()
writer.SetFileName('test.vtk')
writer.SetInputData(mesh)
writer.Write()
```
I noticed that, although the `point` is given with some precision, the
output `test.vtk` file only contains 6 digits of accuracy,
```
0.123457 3.14159 0
```
The numpy data type hosts 8 digits.

Is this a bug or expected? How to mitigate?

Cheers,
Nico

Hi,


When I test a sample of vtkVolumeTextureMapper2D, the project is OK. But when it replaced by its subclass vtkMesaVolumeTextureMapper2D. It makes a build error: unresolved external symbols "vtkMesaVolumeTextureMapper2D". 


Where is the problem? Dose it in cmake file or the VTK library setting?


My VTK version is 5.10.1.

hi aashish,
Im working on an 2d/3d overlay project...im running an algorithm in ITK that
gives a transform matrix as output... i want to apply this output to the 3d
volume... my main goal is to place the 3D image (with some intial transform)
over the 2D xray image and  rotate 3D volume (keeping the 2D image steady)
such that the 2D image and 3D volume appear to be aligned.... yes i have
tried the examples and as u have said both the volume as well as the 2D
image move together..a the moment im trying another example called "Layered
renderers" from wiki.. but the same issue persists... should i set some
parameter like the interactor "off"? please advice...
regards
Vishal

This smells very much like the vtk_array data being interpreted as single
precision even though
```
  Data type: double
```
Cheers,

Subject: [vtkusers] trigger the execution of a vtkThreadedImageAlgorithm
 derived filter by calling Update()
In-Reply-To: <56714C41.3080500@kcl.ac.uk>

Hi all,

I just fixed it. The problem was that I needed to run Update() on the 
image source filters. So my previous code does execute.

There was a bug though: I was trying to calculate a number (the SSD 
value) by combining the value obtained from each thread. To achieve 
this, My previous code has to be changed to the code below. The main 
issue was when to define the return value, how to add return values from 
multiple threads and dealing with mutual exclusion.

I would appreciate if someone has a link to a user guide for 
implementing these sort of filters in a more efficient way.

Regards,

Alberto

Subject: [vtkusers] vtkFastSplatter broken?
Message-ID: <1450353507849-5735566.post@n5.nabble.com>

Hi all,

I was hoping to use vtkFastSplatter so I took a look at the test. However,
it doesn't work how I expected (or how it should, I think).

The example places 5 splatters at various coordinates. But I can't control
the position of those splats. If I comment out all but the first splat and
then change the coordinates, it doesn't move!

Below is the relevant code, can someone confirm that if they change point[0]
and point[1], nothing happens? Then, try adding in a second splat (remember
to change Points->SetNumberOfPoints( 1 ) to 2), changing its coordinates and
observe that weird things start happening...

Subject: [vtkusers] python: GetNumberOfScalarsInFile identify only one
 scalar instead of four in binary Legacy vtk
Message-ID: <5672BC8F.4000601@mech.kth.se>

Hej,

I have tried to look through the archives of the mailing-list but 
couldn't find an answer to my problem.

A colleague of mine gave me a bunch of binary Legacy vtk files. They are 
structured points with 4 scalars. Here is how I try to read them in python

    import numpy as np
    import vtk

    reader = vtk.vtkStructuredPointReader()
    reader.SetFileName(filename)
    reader.ReadAllScalarsOn()
    reader.Update()
    reader.GetNumberOfScalarsInFile()


When I execute the last command, it returns that there is only one 
single scalar in my file though I actually have four of them. Would 
anyone have an idea of what is going on and how I could fix this?

Regards,
JC

Instead of GetNumberOfScalarsInFile() try
reader.GetOutput().GetPointData().GetNumberOfArrays() and
GetCellData().GetNumberOfArrays(). You can also get the number of single
component arrays.

In VTK the scalar designation (see vtkDataSetAttributes) is sort of an
anachronism. The "Active" Scalar array designation marks one array as the
default that filters will operate on if they aren't told specifically what
array to work with.

wow the link solve the problem, thanks a lot. It looks like we need to use
different cmake statements e.g.
instead of this:
find_package(VTK COMPONENTS
  vtkFiltersSources
  vtkInteractionStyle
  vtkRendering${VTK_RENDERING_BACKEND}
)
  
we should use this:

find_package(VTK 6.0 REQUIRED NO_MODULE)

Subject: [vtkusers] Texture and Clamp
Message-ID: <5672E0BF.3010709@yahoo.it>

Hi
I have some problems with textures.
Looking to this address ( https://open.gl/textures ), especially looking 
at the first 4 images,  I found that it is possible to 'cut' the texture 
exactly at the end of the (S/T) range (0-1). I am referring to the 
graphic result obtained with "GL_CLAMP_TO_BORDER", that it is probably 
exactly what I need.

The problem is that I always get a result like "GL_CLAMP_TO_EDGE"

Of course I use RepeatOff(), but then trying 
EdgeClampOff()/EdgeClampOn() I can not see any change.
Is it a problem related to my graphic card (GEFORCE 310M) or it is 
normal to have this behaviour?

Thanks
Matteo

Hi Nico,

I can confirm that I see the same behavior. I added the following lines 
to the end of your script:

'''
rdr = vtk.vtkUnstructuredGridReader()
rdr.SetFileName('test.vtk')
rdr.Update()
loc = rdr.GetOutput()
pts = numpy_support.vtk_to_numpy( loc.GetPoints().GetData() )
print pts
print pts.dtype
'''
and regardless of whether I called writer.SetFileTypeToASCII(), the 
dtype was always float64, but there was a loss in precision.

If you can get away with writing a binary file, might I suggest using 
vtkXMLUnstructuredGridWriter? With the above code, python printed with 
the correct precision and dtype (obviously changing to 
vtkXMLUnstructuredGridReader).

Cheers,
Nishad.

Subject: [vtkusers] Announce: vtk 7.0.0 release candidate 1 is ready
Message-ID: <CANjZAi82KacSXK8TDPdhgtCe2AxXVs+-XH3xBarQj1fyt80Y7Q@mail.gmail.com>

The VTK developement team is happy to announce that VTK 7.0 has entered
the release candidate stage!

You can find the source, data, and vtkpython binary packages here:

http://www.vtk.org/download/#candidate

Please try this version of VTK and report any issues to the list or the
bug tracker so that we can try to address them before VTK 7.0.0 final.

The official release notes will be available when VTK final is released
in the next few weeks. In the meantime here is a preview:

The big news is that the OpenGL"new" backend is now the default and that
VTK is for the first time compatible with Python 3.

Other new functionality includes:
- the introduction of the Flying Edges SMP optimized (very fast) isocontour
filter
- a new and improved vtkPUnstructuredGridGhostCells filter that efficiently
creates ghost cells in DMP parallel contexts.
- allow the Python Global Interpreter Lock (GIL) for multithreaded Python
routines
- offscreen rendering through EGL now supported
- remove vtkFreeTypeUtilities

Improvements to existing functionality includes:
- optimizations to the Contingency Statistics class which provides a
significant performance boost when using only integer or floating point data
- improved MPAS file handling including including arbitrary vertical
dimensions and more general attribute reading
- modernize depth sorting code. In tests the improved depth sort is 2 to 3x
faster than before.
- fixes to the ExodusWriter, especially when handling side sets and node set
data.
- updates to the PLY Writer

Some of the changes that affect building and using VTK in applications
include:
- the OpenGL2 backend requires newer rendering capabilities than its
predecessor
- QtWebKit is no longer part of the Qt build group and thus easier to do
without
- vtkStreamer and related classes are deprecated; use vtkStreamTracer
instead.
- a new option (when building with newer CMake) to build with C++11 support
- add support for Visual Studio 2015
- Java 1.6 is now the minimum version that is tested; 1.5 may not work
- remove support for OSX10.5 Leopard and the Carbon (OSX9 compatibility
layer) API
- remove support for gcc 4.1

And many bug fixes across the codebase.

We hope you enjoy this release of VTK! As always, contact Kitware and
the mailing lists for assistance.

Hey,
i checked the configuration. The target platform is x64. In the taskmanager the process is also marked as x64. Also I checked the libs and dlls. But i think it is not possible to link 32bit files.?Can you tell me which settings can influence such behaviour?I use the preprocessor define: vtkRenderingCore_INCLUDE and the header includes the following lines.?
#define vtkRenderingCore_AUTOINIT 2(vtkInteractionStyle, vtkRenderingOpenGL)#define vtkRenderingVolume_AUTOINIT 1(vtkRenderingVolumeOpenGL)? 
Can this maybe corrupt the memory?
Thanks for your help!Andi

Andi,
I assume that your VC++ x64 platform configuration is set properly?
All libs throughout your build chain should be x64 too.
Are your link settings correct i.e. MachineX64 (/MACHINE:X64)?

Subject: [vtkusers] 64Bit memory problems

Hello,

I developed a tool to perform different types of Volume Rendering for Windows plattform. The code is written in C++. I use Visual Studio 2013 and VTK 6.1. So far everything is developed in 32bit and works very well. 
Now i want to switch to 64 bit. I rebuilt VTK with CMake for 64Bit and set VTK_USE_64BIT_IDS. I checked some of the VTK examples and it works. But not in my project. As soon as i create a VTK object it seems that the objects memory is corrupted. The program crashes afterwards with memory access errors. The non VTK parts runs stabil. It is strange. For testing i create a vtkRenderWindow right after entering the main entrypoint. When i check the member the Interactor for example points to 0x000000000000001. That looks like corrupted memory because the interactor member is set to zero in the constructor.
I don't know how to fix it, so maybe somebody had similar problems and knows what I have to do. Is there maybe a Project configuration which i should keep an eye of? I guess CMake is not the problem because the VTK examples with the same VTK dlls work perfect.

Please help me and thanks in advance
Andi

Subject: [vtkusers] vtkPropPicker Pick method access violation
Message-ID: <1450433924342-5735579.post@n5.nabble.com>

Hello,

I would like to develop a medical application with VTK and C++ Builder
(dicom files)

I compiled succesfuly VTK 5.6.1 in C++ Builder XE2. I modified and installed
a Borland package with a VTK viewer.

I would like to know the position (X, Y) of the mouse in the viewer and the
corresponding gray level.
The method "Pick" of the vtkPropPicker class cause access violations and I
don't know why ...

The same code in C++ Builder without using the Borland VTK viewer (in a
MS-DOS console application) works fine.

Best regards,

Hi Gregory,

I stack trace, code, link to some code, or some other hints would be
helpful for people on the list to give you some ideas of what might be
happening. I'm not sure how many people are using Borland these days, but
maybe someone can chime in with some help.

Hi people,

I'm facing the same issue described here. Additionally, I tried to change
the cursor using Qt setCursor method, but again I had no luck. Has anyone
had this problem before?

Thanks,

Joao.

Thank you for your response,

I found the problem. In fact, I used a vtkSmartPointer into a local method
of my VCL Form. I sent to the callback funtion via the setter method : 
	void SetPicker(vtkPropPicker *picker)
	{
		this->m_Picker = picker;
	}

and in this callback function, when I used the "m_Picker" instance variable,
the program failed with access violation. I saw that the reference count was
0 for "m_Picker".

So, I used a vtkPropPicker instance in the header of my VCL Form (create on
constructor of the Form)

At the moment, my program works fine. As I am beginner in VTK, I will have
other problems certainly

Best regards,

Hi Gregory,

I stack trace, code, link to some code, or some other hints would be
helpful for people on the list to give you some ideas of what might be
happening. I'm not sure how many people are using Borland these days, but
maybe someone can chime in with some help.

Eurographics 2016 Symposium on Parallel Graphics and Visualization
(EGPGV 2016)
===============================================================================
June 6-7, 2016, Groningen, the Netherlands
Co-located with EuroVis 2016
www.egpgv.org



Call for Papers
================

The importance of parallel computing is increasing rapidly with the
ubiquitous availability of multi-core CPUs, GPUs, and cluster systems.
Computationally demanding and data-intensive applications in graphics
and visualization are strongly affected by this trend and require novel
efficient parallel solutions. The aim of this symposium is to foster the
exchange of experiences and knowledge exploiting and defining new trends
in parallel graphics and visualization.

The proceedings of the EGPGV Symposium will be published in the
Eurographics Proceedings Series and in the Eurographics Digital Library.
Best papers from the EGPGV symposium will be invited to submit an
extended journal version to IEEE Transactions on Visualization and
Computer Graphics.

Focusing on parallel computing, the symposium seeks papers on graphics
and visualization techniques, data structures, algorithms, and systems for:

- large-data
- clusters
- (multi-)GPU computing, and heterogeneous, hybrid architectures
- out-of-core
- hybrid distributed and shared memory architectures
- grid and cloud environments

In particular the symposium topics include:

- computationally and data intensive rendering
- scientific visualization (volume rendering, flow and tensor visualization)
- information visualization and visual analytics
- simulations for virtual environments (physics-based animation,
collision detection, acoustics)
- mesh processing, level-of-detail, and geometric methods
- visual computing (image- and video-based rendering, image processing
and exploitation, segmentation)
- scheduling, memory management and data coherence
- large and high resolution displays, virtual environments
- scientific, engineering, and industrial applications



Important Dates
=================

Paper Submission:    February 19, 2016
Author Notification: April 1, 2016
Camera-Ready papers: April 15, 2016

I reported a bug issue id 0015892.  It's a bug for opengl2.  Extra cells
are shown in 2nd/3rd renderer layers.  I've seen the bug in 6.3 and
7.0rc1.  I've checked with the official 64 bit python release and my own
6.3 builds.

Subject: [vtkusers] CMake, UseVTK.cmake and CUDA incompatibility
Message-ID: <5674488C.60709@gmail.com>

Dear all,
I'm experiencing a CMake problem caused by UseVTK.cmake (VTK version 6.3 
release).
I have a large CMake project with multiple targets. Some use VTK, some 
use PCL (which uses VTK). One uses neither, but does use the Nvidia CUDA 
package. Here is what happens:

1) find_package(PCL) in my CMake code automatically runs PCLConfig.cmake.
2) PCLConfig.cmake includes UseVTK.cmake after find_package(VTK) is 
successful (note: this is the intended use, I'm assuming there is 
nothing wrong with this).
3) UseVTK.cmake adds a trainload of flags to CMAKE_C_FLAGS and 
CMAKE_CXX_FLAGS CMake variables directly (!!Something wrong with this 
schema -- discussed later!!).
4) Even though a certain target does not link/use VTK or PCL, the way 
the CMake default CUDA handling works is that these flags are passed to 
the nvcc compiler, i.e. here's what gets executed:

---------begin quote-----------
/usr/local/cuda/bin/nvcc -M -D__CUDACC__ 
/home/<omitted>/quickshift_gpu.cu -o 
/home/<omitted>/reco_segmentation_generated_quickshift_gpu.cu.o.NVCC-depend 
-ccbin /usr/bin/c++ -m64 -D_DEBUG -DvtkRenderingContext2D_AUTOINIT=1 ( 
vtkRenderingContextOpenGL ) -DvtkRenderingCore_AUTOINIT=3 ( 
vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingOpenGL ) 
-DvtkRenderingVolume_AUTOINIT=1 ( vtkRenderingVolumeOpenGL ) 
-Dreco_segmentation_EXPORTS -Xcompiler 
,\"-Wall\",\"-std=c++11\",\"-fPIC\",\"-g\" -DNVCC 
-I/usr/local/cuda/include -I/usr/local/include/vtk-6.3 
-I/usr/local/cuda/include
---------end quote-------------

-- instead of simply:

---------begin quote-----------
/usr/local/cuda/bin/nvcc /home/<omitted>/quickshift_gpu.cu -c -o 
/home/<omitted>/reco_segmentation_generated_quickshift_gpu.cu.o -ccbin 
/usr/bin/c++ -m64 -D_DEBUG -Dreco_segmentation_EXPORTS -Xcompiler 
,\"-Wall\",\"-std=c++11\",\"-fPIC\",\"-g\" -DNVCC 
-I/usr/local/cuda/include -I/usr/local/cuda/include
---------end quote-------------

Whereas the latter command funs fine, the former fails with "nvcc 
fatal   : A single input file is required for a non-link phase when an 
outputfile is specified".

Now, syntax such as "set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} 
${VTK_REQUIRED_CXX_FLAGS}")" is not supposed to be used in UseXXX.CMake 
files, it is intended for CMake macros/functions(1). Clearly, it causes 
unintended problems. The modern way to do things like this is to add the 
flags to something like VTK_CXX_FLAGS, so that the user may use the 
target_compile_definitions(...) command (2) to add them to specific 
targets. Ideally, off course, the preprocessor definitions should be set 
in config header files that are configured by cmake *at the time of VTK 
CMake generation*, such as /Common/Core/vtkConfigure.h.in. This way they 
are defined when the target project includes the headers (which is done 
any way), and avoid the need for separate target_compile_definitions calls.

1) How do I get around this and get CUDA working on this target without 
losing PCL/VTK support for other targets?
2) Is there any rationale behind setting compiler flags in CMake instead 
of in header config files? Is there any rationale behind explicitly 
modifying the CMake flags variables in the UseVTK.cmake script?

Thanks,
Greg

Subject: [vtkusers] How to control frame duration in vtkFFMPEGWriter?
Message-ID: <1450473418344-5735589.post@n5.nabble.com>

Hi all,

I'm trying to control the frame duration of a vtkFFMPEGWriter generated
video, but I'm not having luck. I'm asking myself why the method
vtkFFMPEGWriter::SetRatio accepts a integer as input instead of a floating
point type. If so I could set, for example, a value of 1/5 and control the
frame duration. Any thoughts about that?

Thanks,

Jo?o.

Subject: [vtkusers] Migrate from VTK 4.2 to 7.0,
	supporting functions and libraries
Message-ID: <1450476059781-5735590.post@n5.nabble.com>

Hi Everyone,

I'm a newbie to the VTK and I'm upgrading my application which is using VTK
version 4.2 to 7.0.
 
I got some errors from compiling using Visual Studio C++ 2010
error C2039: 'SetGlobalAntiAliasingToNone' : is not a member of
'vtkTextProperty'
error C2039: 'SetInput' : is not a member of 'vtkPolyDataMapper'
error C2039: 'RenderTranslucentGeometry' : is not a member of 'vtkActor'
Which equivalents function to these above functions I can use from version
7.0

I notice the built libraries name changed, for example 
vtkRendering.lib (version 4.2)
and a list of vtkRendering-----.lib libraries.
Which libraries should I use? Can I group the list of libraries into 1 as
vtkRendering.lib, if yes, how?

Thanks in advance,
Dennis

I would stop right there. This most likely will not be an easy task
for someone that is new to VTK.

subset of the imported files. I can then use the vertices and normals of
the triangles for aperture processing, but while I have no problem with
importing stl files and rendering them, I don't have a fast way of
isolating the visible triangles for a given angle. I read the example on
the wiki, and was wondering if you could give me your advice. I don't want
to display it each time, as I need to extract the cell id list of visible
triangles for a large set of spherical coordinates.

I can then use the cell ids to pass the polygons to my function for
processing for area, orientation and other things.

Many Thanks for your time

Tim

Hi,

Is it possible to select the curves to be referenced in the legend of a 
chart plot?

Whenever I SetShowLegend to true, the legend shows all the curves, 
included those named with an empty string.

Message-ID: <CAO40JR6a2xiOqbKazhG3n3ETMX+gQeq0xgWPVQy0q2CLWHY7iw@mail.gmail.com>

Dear vtk users and developers,
I am currently trying to run the two android examples with OpenGL ES 2.0
backend available in vtk 7.0.0 rc1, on an ARM Mali 400 MP GPU.
Unfortunately, I am not able to run neither of them on the device.

NativeVTK crashes at Rendering/OpenGL2/vtkShaderProgram.cxx, line 399
with "Shader object was not initialized, cannot attach it."
See also http://pastebin.com/Wvew3gen for the full log.

JavaVTK appears to interact correctly with the user (see
http://pastebin.com/w3Sdu7CC ), but only a blue background is shown. The
trace file obtained with the android device monitor is available at
http://filebin.ca/2QdKao08I3lb/trace1.gltrace

Do you have any suggestion on what could be the issue?

Thanks

Hello,
I am successfully using QVTKWidgets with one nagging exception.  Despite my best efforts at handling the smart and non-smart pointers, I get an exception caused by something in VTK when trying to exit the application.

All smart pointers in VTK (and ITK) are handled by setting to NULL rather than deleting, and all is fine until the very end, when something during the Qt deletion ends up calling ~vtkFreeTypeToolsCleanup which causes the exception.

I do not know if this helps but I am calling theQvtkWidget->SetRenderWindow(NULL); before delting the ui (and which does not give any problems).  I am not doing anything for the interactors, as unclear whether I should even be doing this, and I do not see a corresponding call for the interactors anyway.

Thoughts?

Thank you,
Andy

Subject: [vtkusers] Highlight vtkBoxWidget face by moving the mouse
Message-ID: <CAMK600UMbypJyxwgntv9Uf4WdC=wVQ_6KPVxxvVW7nv0yvOBRA@mail.gmail.com>

Hi everyone !
I am trying to highlight a vtkBoxWidget face, when the mouse position is
over it, and without picking it.

I have this for the moment :
case WM_MOUSEMOVE:
            LPPOINT PT=(LPPOINT)malloc(sizeof(LPPOINT));
            ::GetCursorPos(PT);
            vtkSmartPointer<vtkPropPicker>
picker=vtkSmartPointer<vtkPropPicker>::New();
            picker->Pick(PT->x, PT->y, 0, this->ren);
            double* pos = picker->GetPickPosition();

and now I don't know what to do because if I get the actor of the picker,
the whole BoxWidget comes and I just want the face.
Any help?
Thank you,
Am?lie

Could you paste your widget destructor? I use QVTKWidget regularly and in the
QDialog (or other kind of parent) destructor I just delete ui.

If this is Visual Studio (and vtk is built as dlls) make sure you are
using VTK compiled with the version of Visual Studio that you use. And
if you installed vtk as Release make sure you only build your
application as Release. Same goes with debug. The reason for this is
you will have more than 1 heap if you use a different version of
visual studio or are mixing debug and release. Having more than 1 heap
will lead to random looking application crashes because you can not
safely allocate memory in 1 heap and free it in a second.

I don't know exactly how to do what you want, but you might want to take a
look at vtkBoxWidget::HighlightFace(int cellId) for some clues how to do
this.

Hope that helps,
Cory

Dear all,

I am currently using some vtkLogoWidget in my java application.
I would like to make them static in some way. Is there something like
setDraggable(false) for this kind of object?

Regards

Vincent

You might try some of the following member functions:

EnabledOff();
Off();

The full list of member functions is available here:

http://www.vtk.org/doc/nightly/html/classvtkLogoWidget-members.html

Let us know if these work.

Thank you for your fast reply.

I tried both of them actually. But they hide the widget, they don't make it
undraggable.
I also tried to disable picking management, and selection but there is no
difference.

Is it possible that it comes from the java wrapper not implementing some
functionalities which are actually present in C++?

To give you more information, here is part of the code:

As you can see I also tried to disable selection, picking and draggability

Skimming the code in vtkLogoWidget's parent class vtkBorderRepresentation,
it looks like there is no way to disable dragging at the moment.

One could change the code in
vtkBorderRepresentation::WidgetInteraction(double eventPos[2]) in the
switch statement case for vtkBorderRepresentation::Inside to also check if
dragable is set to off, e.g.

    case vtkBorderRepresentation::Inside:

      if ( this->Moving* && this->Dragable*)
        {
        par1[0] = par1[0] + delX;
        par1[1] = par1[1] + delY;
        par2[0] = par2[0] + delX;

        par2[1] = par2[1] + delY;

        }
      break;

Note the change in bold. Would you want to give this a try and see if that
works?

Thanks,
Cory

Hi John,

Thanks for the advice.
I understand that it is not an easy task; Unfortunately, I have to update
the VTK from version 4.2 to 7.0 and my application which built with visual
studio C++ v6.0 to visual studio 2010.
I have been able to build the VTK version 7.0 rc1 with visual studio C++
2010,
and been able to compile my application (with few line of code commented
out).
I'm working on linking my application and VTK libraries using visual studio
C++ 2010.

Best,
Dennis

Subject: [vtkusers] VTK and Yocto
Message-ID: <CAMikMhDBJfeXrE+hmX4XbinppdrRAM58mBuVqqY-ZY5S9frNEw@mail.gmail.com>

Hi all,

I'm working on a project that integrates Qt's QML with VTK. I inspired
myself from this code to integrate VTK into QML:
https://gist.github.com/nocnokneo/c3fb01bb7ecaf437f7d6

For testing purpose, I was able to run the application (QML + VTK) under a
Ubuntu 15.10 Server install which does *not* install the X server. It does
contain a /usr/lib/libGL.so though, which VTK seems to require, even if QML
uses the "eglfs" platform plugin (OpenGL ES 2.0, see
http://doc.qt.io/qt-5/embedded-linux.html).

This project is meant to run on a device of which the OS is built using
Yocto *without *X11, similarly to what Ubuntu Server provides. But while I
could build VTK, QML and my application on my Ubuntu workstation and copy
these files to the Ubuntu Server machine to run, I can't do this for the
real project running from a Yocto image. I need to compile VTK (in addition
to any other library) through the Yocto build system (bitbake).

The only recipes I've found for VTK on Yocto is this one from Marc Ferland:
https://github.com/mferland/meta-vtk
Unfortunately:
1) It is 2 years old and applies for an old release of VTK
2) It assumes that Yocto is including X11 (through the
DISTRO_FEATURES="x11")
3) It is targeting OpenEmbedded (instead of Yocto)

After adapting the recipe for VTK 7.0.0.rc1, I cannot build it. From the
original recipe, I removed dependencies on x11-related libraries
(virtual/libx11 virtual/libgl libxt xserver-xorg-extension-glx) and
everything Python related.

What I don't understand is that recipe uses "-DVTK_USE_X:BOOL=OFF". But I
still get errors dues to missing X11 libraries. For example, I am getting:

| CMake Error at CMake/FindPackageHandleStandardArgs.cmake:97 (MESSAGE):
|   Could NOT find OSMesa (missing: OSMESA_LIBRARY OSMESA_INCLUDE_DIR)
| Call Stack (most recent call first):
|   CMake/FindPackageHandleStandardArgs.cmake:288 (_FPHSA_FAILURE_MESSAGE)
|   CMake/FindOSMesa.cmake:45 (find_package_handle_standard_args)
|   CMake/vtkOpenGL.cmake:59 (find_package)
|   ThirdParty/glew/vtkglew/CMakeLists.txt:3 (include)



My questions are:
1) Can I compile VTK *without *having any X11 libraries?
2) What does the cmake flag VTK_USE_X do?
3) Does it make sense to build VTK without x11 if I will be using VTK from
C++ including these headers: QOpenGLFunctions, QQuickFramebufferObject,
QOpenGLFramebufferObject, vtkGenericOpenGLRenderWindow (like at
https://gist.github.com/nocnokneo/c3fb01bb7ecaf437f7d6)?
4) How come I was able to run my QML+VTK example on the Qt platform EGLFS
on a distro without X11?

Thanks for any clarification!

Regards,

Nicolas

Subject: [vtkusers] Cloud of points to nonconvex surface
Message-ID: <1450730934363-5735619.post@n5.nabble.com>

Hi guys.

I am trying to perform segmentation of 3D objects using the method described
in [1]. The method has basically two steps 1) detection of points on the
surface of the object of interest and 2) fitting the points by a closed
parametric surface. I am looking for alternatives for the step 2. Please,
check the enclosed image to see what my cloud of points look like. Do you
guys think there is anything on VTK that I could use to generate a closed
surface from these points? Is the class vtkSurfaceReconstructionFilter a
good way to go? Not sure this class is able to produce closed surfaces
though. I would appreciate any help.

Thanks a lot,
Matheus Viana

There is a lot that has changed in 11+ years of development. It will
not be a simple substitution.

You can not combine the libraries into a single library. The simplest
way to use vtk is to generate your Visual Studio project for your
application using CMake.

Hi John,

Thanks again for the advice. I have been exercised with the CMAKE 3.41 to
configure build option for Visual Studio C++ 2010. I'll continue to exercise
the configuration options.

Best,
Dennis

If you are using CMake to generate your project file you do not list
the libraries you have to link your application with. You use
${VTK_LIBRARIES} your TARGET_LINK_LIBRARIES instead of listing
individual libraries.

Here is an example:

As a follow-up to my own question, I was able to go a little bit further
VTK's build process.

The error I've pasted (Could NOT find OSMesa)was fixed by compiling mesa
with --enable-osmesa. For this I created a file named named
*mesa_%.bbappend* in my layer's *recipes-graphics/mesa/* directory. That
might not be the optimal solution (or even a working one) but at least the
build process went a little bit further.

The error I'm getting now is one that I have seen last week when trying
multiple things in the Yocto build system.

Running cmake fails and I have a hard time identifying the source of the
problem. The problem surely comes from not understanding properly the Yocto
build system. Even though I am building for an x86_64 NUC device from an
Ubuntu 14.04 x86_64, the compilation by bitbake/yocto is a
*cross-compilation*.

The more I think the more I believe my problems comes from badly setting up
that cross-compilation. Yocto should be doing it but VTK requires some
extra work. Marc Ferland's patch located in his layer (
https://github.com/mferland/meta-vtk/blob/master/recipes-vtk/vtk/files/0001-vtkCompileTools-Add-a-CompileTools-group.patch)
adds a "vtkCompileTools" group. Would that still be necessary to
cross-compile VTK v7.0? The patch does not apply to VTK 7; I tried to
re-create it but either the problem is elsewhere, VTK shouldn't be patched
or I'm doing it wrong.

This post by Tim Thirion describe a new (as of VTK 6.2.0) way to
cross-compile for Android or iOS: http://www.kitware.com/blog/home/post/860
I haven't looked yet in VTK's CMakeLists.txt what these options do but
could that be a lead?

As a reference, here is how cmake was called by bitbake:

which is not really helpful.

Any clue or suggestion as to how to cross-compile VTK?

Thanks!

Hi,

I tried what you suggested. So, I made the change in
vtkBorderRepresentation.cxx, I recompiled everything, and used the new
vtk.jar in my application.

Unfortunately, it does not solve the issue. The logos are still dragable.

Subject: [vtkusers] Problem with vtkInteractorStyleImage
Message-ID: <1450771333999-5735629.post@n5.nabble.com>

Hello,

I continue my medical application and I have some trouble with the
"vtkInteractorStyleImage" : VTK 5.6.1 with C++ Builder XE2.

I subclass the interactor style in my application as : 
http://www.cmake.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents
<http://www.cmake.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents>  

Like :
class MouseInteractorStyle1 : public vtkInteractorStyleImage	
{
public:
	static MouseInteractorStyle1* New();
	vtkTypeMacro(MouseInteractorStyle1, vtkInteractorStyleImage);

	virtual void OnLeftButtonDown()
	{
		// Forward events
		vtkInteractorStyleImage::OnLeftButtonDown();
	}

	virtual void OnRightButtonDown()
	{
	  // Forward events
	  vtkInteractorStyleImage::OnRightButtonDown();
	}
};

But the line vtkInteractorStyleImage::OnLeftButtonDown(); is not called ...
because I do not have the "window/level" event.

Thanks,

Best regards,

The QVTKWidget2 class is in this library:

    vtkGUISupportQtOpenGL

Did you add it to your link line?

Hmm. Seems that there's some issue with the way the OpenGL context is
set up? Anyone with more knowledge about this have an idea?

Why do you use "vtkLogoWidget" if you don't want it to be draggable?

Hi John,

I'm using CMAKE to generate VTK project file and using Visual Studio C++
2010 to generate VTK libraries.
After the VTK libraries have been generated, I used VS C++ 2010 to configure
my application which include the link to VTK libraries.

I'm not using CMAKE to generate my application project file.

Thanks for the link to the tutorial, I need to study the VTK.

Best,
Dennis

Message-ID: <CADhi_O6mU1SD+onHnouFyNnRncevO8Ux3pXDvGz4un72PVxGSg@mail.gmail.com>

Good day everyone.

I'm trying to build VTK for PCL library. Well VTK itself is compiled
like a charm, without any error. But inside some the PCL files are
some dependencies to those files:

#include "vtkgl.h"
#include "vtkOpenGLExtensionManager.h"
#include <vtkVisibleCellSelector.h>

And me and my compiler can't find those.

It looks like file vtkgl.h should be generated by cmake and put into
"/Rendering/vtkgl.h". But there is none. What settings should i use in
Cmake for VTK? Or that file is not being generated anymore? What am i
doing wrong?

If you're interested my settings you can see in the attachments to the
letter (not sure how attachments work in mailing list).

Anyway than you, and have a good day.

Yuri.

vtkgl.h can be replaced with vtk_glew.h

the extension manager is not in the new backend but glew should provide any
extension checking support you need although with a different interface

I am not sure about vtkVisibleCellSelector

Thanks
Ken

If you are using the generic Rendering API (vtkActor/vtkCamera/etc) then
code should mostly work unchanged. If you are directly working with the
OpenGL implementation then the conversion really depends on what you were
doing as the implementation is fairly different. In terms of the two
specific issues you mentioned vtkgl.h can probably be replaced with
vtk_glew.h, I do not recall what vtkOpenGLHardwareSupport does but there is
no match for that class in the new backend. Given that you have a class
named vtkVertexBufferObject I am guessing you are getting into very
specific implementation details so the conversion may not be trivial. On
the plus side the new back end includes classes such as
vtkOpenGLVertexBufferObject so ...  If you have further
questions/roadblocks let me know and I'll try to point you in the right
direction.

P.S. vtkOpenGLPointGaussianMapper in the new backend may be worth a look
too as it renders both points and splats etc.

Thanks
Ken

Subject: [vtkusers] Issue when setting number of ticks on a vtkAxis
Message-ID: <1450957386793-5735645.post@n5.nabble.com>

Hi VTK Users,

I'm having an issue when defining the number of ticks of vtkChartXY bottom
axis, even using SetNumberOfTicks method. The axis values are shown as time
stamp strings (by using SetCustomTickPositions). Since there are many
values, they appear overlapped (as shown in the attached image). I would
like to show only 2 ticks as implemented in the code bellow:

vtkSmartPointer<vtkDoubleArray> timeStamps =
vtkSmartPointer<vtkDoubleArray>::New();
vtkSmartPointer<vtkStringArray> timeStampStrings =
vtkSmartPointer<vtkStringArray>::New();
vtkSmartPointer<vtkDoubleArray> scalars =
vtkSmartPointer<vtkDoubleArray>::New();

vtkSmartPointer<vtkChartXY> chart = vtkSmartPointer<vtkChartXY>::New();

// Populate the three arrays and set up vtkTable and vtkChartXY

vtkSmartPointer<vtkAxis> bottomAxis = chart->GetAxis(vtkAxis::BOTTOM);
bottomAxis->SetNumberOfTicks(2);
bottomAxis->SetCustomTickPositions(timeStamps, timeStampStrings);

<http://vtk.1045678.n5.nabble.com/file/n5735645/Screen_Shot_2015-12-24_at_08.png> 

Thanks for any help.

Subject: [vtkusers] vtkChartXY + setTitle + Tcl
Message-ID: <567D13A8.9080307@telefonica.net>

Hello,

In my efforts to use vtkChartXY from Tcl scripts I write:

vtkChartXY chart

Now, if I want to set a title, or change the label of an axis, things like

chart SetTitle "Chart"
[chart GetAxis 1] SetTitle "Time"

always throw the following error:

Object named: chart, could not find requested method: SetTitle
or the method was called with incorrect arguments.

 From documentation, seems that the origin of the problem is that 
SetTitle expects as argument an object of class vtkStdString, but all my 
attempts to make use of it were successless.

Any help would be greatly appreciated.

I am using vtk 6.3.

Hi, Matheus

not sure if it is related to VTK, but I've used radial basis function for
implicit surface definitions, developed by Greg Turk from
Georgia Tech

Paper from his page: http://www.cc.gatech.edu/~turk/my_papers/vimp_tog.pdf

there are quite a few of those papers/methods

Code: https://github.com/Kri-Ol/RBF

Hello Mario, not all method are exported (wrapped) to Tcl. The Tcl wrapping
capability is not receiving attention (only python). The method SetTitle
that you are mentioning is one of those methods.

When I need to invoke a method which is not wrapped what I usually do is
implement (in C++) a helper procedure to invoke that method. Attached you
can find an example which expose the SetTitle method for an object of class
vtkAxis.

For instance if you have an object of class vtkAxis:

  set axisX [chart GetAxis 1]

instead of invoking:

  $axisX SetTitle "Seconds"

I should invoke:

  vtkAxisAddon $axisX SetTitle "Seconds"

(vtkAxisAddon is the proc implemented in C++)

If you find this approach useful, I can provide you a full code (based on
CMake) to create the tcl library to expose the method you are needing.

best regards,
Jorge

Thanks, but this is not a viable solution, at least for the moment. Our 
program must be build with any Common Lisp compiler and end users should 
only care on satisfying some additional dependencies (Tcl, Gnuplot, 
VTK). For the moment, as I see it, we have two alternatives:

a) Make 2d plots with vtkChartXY without the ability of changing axes 
labels and title, waiting for a better Tcl support in Vtk, or
b) Use vtkXYPlotActor instead. I have some vtkXYPlotActor examples 
worked out with Tcl which work fine with strings.

At this moment, I am in favor of a).

Since Maxima (maxima.sf.net) became GNU-GPL, we have used Gnuplot as our 
common graphics renderer. The problem is that Gnuplot is not good at 3D 
modeling, and that's why I started to work with Vtk. People is now 
interested in using Maxima together with Vtk, and I'd like to offer end 
users the possibility of 2D graphics with Vtk with the same Maxima 
syntax used for Gnuplot.

Kind regards, and thanks again for your clarifications.

Message-ID: <567F0860.60908@polytechnique.edu>

Dear VTK users:

I realize that the vtkCellDerivatives filter, when 
SetTensorModeToComputeStrain is activated, returns the symmetric part of 
the gradient of the input vector field, which is the linearized strain 
tensor, i.e., not a proper measure of deformation when large 
displacements are involved. Would that make sense to have two different 
modes, SetTensorModeToComputeLinearizedStrain or 
SetTensorModeToComputeSymmetricGradient, and 
SetTensorModeToComputeStrain or 
SetTensorModeToComputeGreenLagrangeStrain? Thanks!

Hi,

I guess that it is because I am still a beginner with VTK developpment and I
found the vtkLogoWidget example on the wiki which was quite close from what
I wanted to do.

However if there is something more appropriate, I would be happy to make the
switch.

I also tried to use only a vtkLogoRepresentation but did not manage to make
it work. Is this what you had in mind?

Regards

Hi Martin,

Changing the name of the SetTensorModeToComputeStrain method to something
else would break backward compatibility which is generally avoided in VTK.
Other options for this include deriving a class to compute non-linear
strain from vtkCellDerivatives if it shares enough of the algorithm with
the linearized version or maybe just creating a new filter.

Cheers,
Andy

Yusuf,

In the code you provide, the clip filter is never executed. You should add
m_Clip->Update(); - for instance just after the setinputconnection.
Not related but you could directly plug the clip filter to the writer (no
need to shallow copy the output of the clip filter):
just replace m_PolyDataWriter->SetInput(m_PolyDataSave);
by m_PolyDataWriter->SetInputConnection(m_Clip->GetOutputPort());
If you do so, calling Write() on the writer will execute the pipeline of
the writer which involves the Clip filter too - so the clip filter would be
called automatically even if you do not explicitly called Update() on it.

Best,
Joachim

It seems that SetCustomTickPositions method doesn't respect the
SetNumberOfTicks method. Any thoughts?

I did some new tests today.
The trick from Cory seems to work finaly! I guess I made a mistake
previously while reimporting the newly compiled VTK.

Now if I add in my app:
logoRepresentation.SetDragable(0);
or
logoRepresentation.DragableOff();

the logoWidget is fixed to its initial location.
If there is a nicer way to do it, I am still open to any proposal.

Regards

Subject: [vtkusers] infinite/continuous grid
Message-ID: <CAOG35ckpP3ntGqiVhEaCSq0cSR6ro8vyQMvqqP7nVv_gp=5SWQ@mail.gmail.com>

Hello,

Is it possible to have infinite/continuous two dimensional grid along a
particular plane. ? By this I mean to ask whether it is possible to
display two dimensional grid, covering the entire render window, as
and how

1. Window is resized,
2. Zoom operation is performed
3. Pan operation is performed

Is it possible to do it in a similar manner as it is available with in
vtkCharts. ?

Thanks

Widget are made for user interaction. But since you can disable that
interaction. I'm guessing that's fine.

Hi Everyone,

I take 1 step back by using VTK version 5.10.1. The output libraries
structure is similar to VTK version 4.2.
Hopefully I can integrate the VTK libraries version 5.10.1 with my upgraded
application.

Cheer!
Dennis

Subject: [vtkusers] Grid overlay on 3D view n world coordinates
Message-ID: <26F54924-EE6A-43FB-9DF8-43CC7404BDA8@me.com>

Hi,

We want to make a grid with 10 mm ( world coordinates) lines over our 3D view in parallel projection mode.

We want the grid to respond to the camera zoom ( I.e. Lines every 10 mm, so when camera moves +Z lines are farther apart ) but not to rotation. 

We've tried a few things like vtkfollower and etc but nothing seems to fit well. 

Is there a known way to do what we want? The grid around the box of the actor is nice, but our client wants the stationary grid.

Thanks

Rick

I think this will simplify your porting task.

Is anyone maintaining the VTK Java wrapper on OS X?

I was able to compile by replacing vtkJavaAwt.h with an empty file,
although now the demo programs do not work when they try to open a window.

Also, the JOGL jar files have been reorganized and VTK-7.0.0-rc1 will not
compile with the most recent version (2.3.2).  I went back to version 2.1.5.

My cmake setup:

cmake -DVTK_WRAP_JAVA:BOOL=ON -DVTK_JAVA_JOGL_COMPONENT:BOOL=ON
-DJOGL_GLUE:FILEPATH=/Users/nairah1/local/src/VTK-7.0.0.rc1/jogl-all.jar

Hi Dennis,

if you try to use VTK7, you can link against only a subset of vtkRendering*
libraries (the ones which your application actually uses),
e.g. vtkRenderingCore-7.0.lib and vtkRenderingOpenGL-7.0.lib.

As you did not specify what kind of application it is, we can only guess
how hard would it be to CMakify
<http://www.kitware.com/news/home/browse/CMake%3F2003_10_30%26Cross-Platform+Software+Development+Using+CMake>
it. If you CMakify your application, linking against VTK can be
accomplished in a simple way provided in this example
<http://www.vtk.org/Wiki/VTK/Tutorials/CMakeListsFile>.

HTH,
D?enan

Message-ID: <CALmcJSBU9ryj3wvCn26ygt+y93yM0A6VrNFktmw1iW-sD+ZNCg@mail.gmail.com>

Hi vtkusers,

   I would like to perform off screen rendering with VTK and output the
rendered content (e.g. interaction with a mouse) into a video (e.g. .avi).
How to achieve this?

   I know that there is a vtkWindowToImageFilter filter, but it seems that
this filter is designed to save individual images instead of a video
sequence. Is there a better way?

Thanks,
WX

Subject: [vtkusers] method to extract regions
Message-ID: <5681B9CB.9070502@gmail.com>

Hey guys,

I use the vtkPolyDataConnectivityFilter from polydata to extract several 
different and more or less unknown regions.
My problem is that I want to extract regions from this filter, but if I 
do this, the update process for all regions takes up to 10minutes:

filter->SetExtractionModeToAllRegions();
filter->Update();
...

for (int i = 0; i < filter->GetNumberOfExtractedRegions(); i++)
{
     extractFilter->InitializeSpecifiedRegionList();
     extractFilter->AddSpecifiedRegion(i);
     extractFilter->Modified();
     extractFilter->Update();
     extractRegionData->DeepCopy(extractFilter->GetOutput());
}
extractFilter->InitializeSpecifiedRegionList();

Background for this: I want to use the points of each region to check 
whether they lie within an object in my binary
mask image. So the pipeline would be like this:

1) Get all Regions
     2) get region /i/
          3) get points of region /i/
              4) check if point /j/ lies within the binary mask /B/     
(/B/_/j/ == 255)
                  4a) if true then add region to the extractFilter and 
break (-> next region /i/)
                  4b) if false then continue with next point /j/
5) Mark all regions red (done easily)
6) Mark some regions green that are above a specific size (can be 
accessed with filter->GetRegionSizes() )
7) Mark some regions yellow (the regions that are extracted during step 
1-4a)

I do not know if the PolyDataConnectivityFilter is the right class for 
this, I think it is.
If I store the extractRegionData in a vector, all regions have the same 
number of points (which is kind of strange) but different number of 
cells (region size == number of cells is correct).

I would now try to get the points from the cells and check the binary 
mask, because the

vtkPolyData->GetNumberOfPoints()

and

vtkPolyData->GetPoint(pointCounter, point);

are not working correctly in this scenario (all regions are extracted 
because every single region has every point?
i did not verify my guess but I think there would be the problem)

The binary mask is a vtkImageData, that could be transformed to vtkPolyData.
The input image (already filtered with vtkMarchingCubes) and the binary 
mask have the same dimensions (x,y,z).

I hope you can imagine what I'm trying to do and have some tips for me, 
if my approach is correct.

Regards
Imre

Thanks Andy.

What about simply adding another mode, e.g. 
SetTensorModeToComputeGreenLagrangeStrain, to the vtkCellDerivatives 
filter? Would the attached patch make sense?

Hi Imre,

I have a connectivity filter that works directly on images, it can label
connected regions according to size and it should be much faster (probably
1000x) than doing voxel checks via polydata:
https://github.com/dgobbi/AIRS/blob/master/ImageSegmentation/vtkImageConnectivityFilter.h
I'll probably be contributing this filter to VTK sometime in the near
future.

It is not clear what you mean by "maximum diameter of an irregular
object".... Can you describe what you're trying to measure more precisely
than that?

A diameter is an attribute of a circle or a sphere, not an irregular
object. And the closest thing to a "maximum diameter" of an object other
than a circle/sphere is typically the diagonal of its bounding box.

But it sounds like you probably mean something different than that, but
it's unclear exactly what...

Hi Martin,

This patch makes sense. It would need a test if you want to get your
changes into VTK. The directions for contributing to VTK are at
https://gitlab.kitware.com/vtk/vtk/blob/master/Documentation/dev/git/develop.md
.

Cheers,
Andy

Dear VTK users,


I am using VTK 6.3 version. I am using four QVTKWidgets in my application, say rightTopWidget, rightBottomWidget, leftTopWidget, and leftBottomWidget. If I add actor in one render window, say leftTopWidget, all the renderwindows display actors. Later if I perform selection in anther window then it shows me this error:


vtkWin32OpenGLRenderWindow (000000EB5FD666A0): Attempting to call MakeCurrent for a different window than the one doing the picking, this can causes crashes and/or bad pick results


Kindly let me know how do I solve this.


Thanks in advance


Warm Regards

Subject: [vtkusers] VTK mesh to Dicom (PACS)
Message-ID: <2293440.76MnMS8vvS@basti-thinkpad-t410>

Hi all,

I was wondering if anyone could point me into the right direction. 

Background: We are working with MR data of the heart and are rendering/
segmenting regions of interest to models (e.g. left atrium). Those are then 
exported to STL by a software called Philips Intellispace Portal and 
subsequently converted to VTK. Those meshes/models are then used in clinical 
routine.

Goal: What we would like to achieve somehow is to store these VTK meshes in a 
PACS for data exchange. From what I have understood so far it is not possible 
to store VTK meshes in a PACS. What would you suggest ? Is this something that 
can be implemented ?

There seems to be some related bits in the Dicom specification but I am stuck 
here.

ftp://medical.nema.org/medical/dicom/final/sup132_ft.pdf


My research also led me to two solutions by medical device vendors who seem to 
have implemented a way to store their model formats in Dicom file(s). One 
solution Ensite NavX by St. Jude Medical seems to store the XML (VTK ascii 
like) content in a private tag and the other company seems to store (VTK 
binary ?) data in private tags as well.

I do have sample Dicom files from both products as well as the file format 
specifications for both products.

I wonder what it would take to come up with a solution based on the specs and 
the sample files. If anyone could point me into the right direction that would 
be great.

Regards,
Sebastian

As long as your PACS doesn't interfer with the contents of your private
tags, you can probably store whatever you want in it. If the private tags
are limited in size, than you could create a hack that and save a binary
blob representing the mesh in the image portion of the data and somehow
encode this hack in other dicom tags. As long as only your software is
accessing the dicom "images" you should be ok. But if some other
application would try to show the images they would display garbage. In
short, as long as you have someway of storing binary data, you can use it.

Regards,
Dov

Here is the relevant excerpt from the spec





What would be the most suitable tool to craft such a Dicom file ?

The other software's spec states this

*V8 3D IO instances are stand alone DICOM entities implemented as Extension1 to the SC 
Image IOD as defined in PS 3.3 ? 2004 Page 104, Table A.8.1.3 - Secondary Capture Image 
Storage SOP Class 1.2.840.10008.5.1.4.1.1.7.*
*Table 3.1 defines the modules to be included in V8 3D IO?s.*
*The 3D Instance Module is the extension to the standard SC Image IOD. It is detailed in # 3.2 
and # 4. All other modules in Table 3.1 are standard DICOM modules.*

Can anyone comment on this ? 

Regards,
Sebastian

The open source gdcm library is easy to use, either from C++ or from
python.

For a C++ example see:
http://gdcm.sourceforge.net/html/GenFakeImage_8cxx-example.html

For python there is also the pydicom library:
https://pypi.python.org/pypi/pydicom/

All of these make it easy to generate dicom files with arbitrary tags. What
is not always clear is what is the minimum set of tags that you need to
provide. But that may be solved by reading a template image and then
modifying all the relevant tags.

vtk also supposedly comes with a dicom writer, but I have no experience
with it.

Regards,
Dov

Thanks Oleg. I still want to find a solution that depends on VTK only.

I tried to use vtkSurfaceReconstructionFilter and I got something close to
what I want but the very bottom and very top are not closed as shown in the
enclosed image.

Do you guys have any idea how I can force the surface to be closed?

Thanks a lot,

Message-ID: <CALmcJSBScpQw0bTXOFMHY-YWnXhhnmq8+kOfum0Tejz3APiNpg@mail.gmail.com>

Hi vtkusers,

   I found the four pane viewer example in the vtk source dir (
http://www.vtk.org/gitweb?p=VTK.git;a=tree;f=Examples/GUI/Qt/FourPaneViewer).
But it was very preliminary. There is a lot of features that are missing
compared to those which are the commercial medical image workstations. Is
there a better four pane viewer? Preferably open sourced.

Thanks,
Mengda

Guys, I just found that setting the parameter SetNeighborhoodSize of
vtkSurfaceReconstructionFilter to a high value (~200) solves my problem.
According to the documentation this would cause problems with very sharp
edges but I don't think I will have such edges in my dataset.

Thanks a lot,

If you want to compute the bounding sphere

Hi David,

   Thanks for your quick answer. I am looking for a light-weight
code/library that just do the four pane window.
Slicer is too big. It is very unstable from my experiences and crashes from
time to time.

Hi Joao,

You are right, the number of ticks setting is ignored when you use
SetCustomTickPositions(). All the positions and labels you provide will be
displayed. You would have to specify the two you want and pass the via
SetCustomTickPositions() to get just two.

HTH,

Eduardo,

I am not aware of a filter that provides the Feret diameter.

Do you have the plane that determines the orientation you want for the
Feret diameter in implicit form (a, b, c, d)? If so, then you should just
need to iterate over each point (x, y, z) in the polydata, compute ax * by
* cz - d, keep track of the minimum and maximum of those computed values,
subtract the minimum from the maximum, and get the desired diameter.

HTH,
Cory

Hello,

Is it possible to have infinite/continuous two dimensional grid along a
particular plane. ? By this I mean to say that the grid should be modified
and displayed as and how,

1. Window is resized.
2. Zoom in/out is performed.
3. Panning is performed.

The grid must be displayed in such a way that it should cover the entire
render window. Similar to the one available in vtkCharts.

Thanks

I recommend using an external program to do video captures. There are many.

Dear VTK users,


I am using VTK 6.3 version. I am using four QVTKWidgets in my application, say rightTopWidget, rightBottomWidget, leftTopWidget, and leftBottomWidget. If I add actor in one render window, say leftTopWidget, all the renderwindows display actors. Later if I perform selection in anther window then it shows me this error:


vtkWin32OpenGLRenderWindow (000000EB5FD666A0): Attempting to call MakeCurrent for a different window than the one doing the picking, this can causes crashes and/or bad pick results


Kindly let me know how do I solve this.


Thanks in advance


Warm Regards

Rakesh,

Not to my knowledge.

You should be able to compute the number of lines you need in each
dimension based on the frustum available from
vtkCamera::GetFrustumPlanes(...). Or you could do something fancy like
place a screen-filling plane source with a custom shader that computes grid
lines based on the interpolated coordinates in the fragment shader.

Hi Cory,

I've solved it partially by rotating the overlapped labels 45 degrees (see
the attached). The issue now is that the labels are above the X axis. I
didn't find any methods in classes vtkChartXY, vtkAxis and vtkTextProperty
to set the labels relative position, so putting them below the X axis. Do
you know how can I fix this?

Thanks,

Joao.

Subject: [vtkusers] How to compute area of counter made by vtkContourWidget?
Message-ID: <tencent_4B84F31E7E3C2D4B0CB9CBB7@qq.com>

Hi all,


I used vtkContourWidget to label a contour on an image. And it also need to compute the area of contour. I tired by an example that first converted the contour by vtkTriangleFilter, and then use the vtkMassProperties to compute the area. The detailed code in a Callback function as follows:
////////////////
	void SetObject(vtkContourWidget * contour){
		m_contour = contour;
	}



	virtual void Execute(vtkObject *caller, unsigned long eventId, void *callData){


		int Num = m_contour->GetContourRepresentation()->GetNumberOfNodes();
		std::cout<<"NumOfNodes:"<<Num<<" "<<m_contour->GetContourRepresentation()->GetClosedLoop()<<endl;


		if (m_contour->GetContourRepresentation()->GetClosedLoop())
		{
			
			vtkSmartPointer<vtkTriangleFilter> triangleFileter = 
				vtkSmartPointer<vtkTriangleFilter>::New();


			triangleFileter->SetInput(m_contour->GetContourRepresentation()->GetContourRepresentationAsPolyData());
			
			vtkSmartPointer<vtkMassProperties> massProp = 
				vtkSmartPointer<vtkMassProperties>::New();


			//massProp->SetInput(triangleFileter->GetOutput());
			massProp->SetInputConnection(triangleFileter->GetOutputPort());


			double area = massProp->GetSurfaceArea();
			//double area = 12;
			std::cout<<"Counter Area:"<<area<<" um2"<<endl;
		}
	}

//////////////////////
When run the project, it will output some warring information in a vtkOutputWindow tha t"Warning: In ..\..\VTK5.10.1\Graphics\vtkMassProperties.cxx, line 120 vtkMassProperties (03636DC8): Input data type must be VTK_TRIANGLE not 3"


When is the problem? Or is there some other way to compute the area of contour made be vtkContourWidget?


Thanks

Same here. It seems a double destruction or wrong order of destruction
because vtkMathInternal is static member of vtkMath.
http://stackoverflow.com/questions/6850009/c-deleting-static-data
<http://stackoverflow.com/questions/6850009/c-deleting-static-data>  
suggests a smart pointer for Gaussian, or remove the destructor.

vtk --version = 6.3
//vtkMath.h
static vtkInternal Internal

//vtkMath.cxx
class vtkMathInternal
{
public:
  vtkMathInternal();
  ~vtkMathInternal();
  vtkMinimalStandardRandomSequence *Uniform;
  vtkBoxMuellerRandomSequence *Gaussian;
  std::vector<vtkTypeInt64> MemoizeFactorial;
};

vtkMathInternal::vtkMathInternal()
{
  this->Gaussian=vtkBoxMuellerRandomSequence::New();

  // This line assumes the current vtkBoxMuellerRandomSequence behavior:
  // an initial vtkMinimalStandardRandomSequence is created.
  this->Uniform=static_cast<vtkMinimalStandardRandomSequence *>(
    this->Gaussian->GetUniformSequence());
  this->Uniform->SetSeedOnly(1177); // One authors home address
  this->MemoizeFactorial.resize(21, 0);
}

vtkMathInternal::~vtkMathInternal()
{
  this->Gaussian->Delete();
}

vtkMathInternal vtkMath::Internal;

I am not aware (but I am also not an expert) of a particular filter or
method
to get the corner points of a surface in general. However, for the
particular
surface that you show, it should not be that difficult, because each of the
corner points is on the bounding box of the grid. So assuming that the
you have collected the points in a vtkPoints object, you can first extract
the bounds and afterwards find the points that are on (closest to) each
of the sides of the bounding box. Not that hard, not immediately obvious
either.

Hi all

Just wanted to let you know that I was able to work around my problem by
using vtkClipPolyData instead of vtkBooleanOperationPolyDataFilter. This
also brings the advantage that the code runs much faster.

Here some code to get the basic idea (not fully equivalent to above code,
but can be made equivalent with just a few lines more):

Hi Yihui Cao

The "3" in the warning message refers to VTK_LINE. From this I infer that
the contour is represented with lines only (a polyline). You have to first
"transform" the line into a polyline, or 

In case your contour is guaranteed to be convex, you can triangulate the
contour surface with vtkDelaunay2D. So, before calling the
vtkTriangleFilter, calculate the Delaunay triangulation on your contour
edges (Python code):


If the contour is not convex, things are a bit more complicated. You can try
to transform the polyline into a polygon. Unfortunately, I haven't found a
simple trick myself. Here some ideas that might help:

Hi Cory,

Same thing here.

Thanks,

Joao.

Subject: [vtkusers] Problems with vtkClipPolyData and vtkImplicitBoolean
Message-ID: <1451525713172-5735713.post@n5.nabble.com>

Hi

I have an issue with vtkClipPolyData, using an implicit function created
with vtkImplicitBoolean. Although it is really convenient to create a
complex-shaped function, it does not behave as expected in regions where two
implicit functions coincide. 

Here is what I do: cut out a cylinder from an arbitrary surface. The code is
found at the end of this post.
1) Define a bounded implicit cylinder by combining (intersecting) one
vtkCylinder with two vtkPlanes: vtkImplicitBoolean.
2) Clip the surface using vtkClipPolyData (at function value 0).

While the clipping works good in general, the clipping is inaccurate in
regions where two implicit functions intersect. Look at the image below
(ignore the red sphere). In white the surface that has to be cut. The green
transparent surface indicates the implicit cylinder function. The cells that
are clipped away by vtkClipPolyData are marked blue. You can see easily that
close to where vtkCylinder and vtkPlane intersect the clipping looks faulty.

<http://vtk.1045678.n5.nabble.com/file/n5735713/imperfect_cut_for_small_angle_of_attack.png> 

I found two issues with vtk related to this:
1) The vtkCylinder function measures the *squared* radial distance from the
surface, while the vtkPlane evaluates the normal distance. This is
inconsistent with the linear interpolation performed when clipping the cells
(e.g. vtkTriangle::Clip()).
2) If two points of a surface triangle are "constrained" by different
implicit functions, the interpolation used when clipping a (triangular) cell
is inaccurate. (This problem occurs only for functions using
vtkImplicitBoolean.)

1) is not actually a bug or issue but the choice of function accentuates the
problem in my case. That's why I would suggest the following change of code
int vtkCylinder.cxx. 



I guess you are pretty reluctant to apply this change because of backward
compatibility. Nevertheless, the result looks considerably better with the
new choice and is more consistent with the linear interpolation when
clipping.

<http://vtk.1045678.n5.nabble.com/file/n5735713/imperfect-cut-after-fix.png> 

But the real issue is 2). When the corners of a triangle "hit" different
implicit functions, the linear interpolation (e.g. in vtkTriangle::Clip())
between the function values is not valid, or at best inaccurate. I've looked
how vtkClipPolyData::RequestData() operates and how it invokes
vtkGenericCell::Clip(...) (or vtkTriangle::Clip() in my case) and I suggest
that this is improved: either by passing a functor to Clip() that allows to
evaluate multiple candidates, or to discretize the edges of these triangles
beforehand. Obviously, this would make the code run slower. But the
precision could be specified, which is often more eligible. 

So here's a question: how can I work around these inaccuracies along the
boundaries of a boolean implicit function?

And along this lines, I'm suggesting two changes in the code:
1) Make the distance function for the cylinder linear.
2) Don't use linear interpolation in those cells that are clipped.
Let me know what you're thinking.

Hi

Two stupid questions

Did you define the macro?


And do you have this line?


I tested your sample and I do receive the events. I tested with vtk-5.10.1
and vtk-6.3.0 on Mac OS. (On Mac OS, I have some issues with vtk-5.10.1 and
the windowing system, but generally the sample was working.)


Here's the complete code I was using:

For custom behaviour of the scene, you might want to derive your own
interactor, as shown in  Mouse Events example
<https://cmake.org/Wiki/VTK/Examples/Cxx/Interaction/MouseEvents>  . You can
then forward those events to your grid object that you actually want to
handle.

VTK also supports callbacks to intercept a certain user event. You can read 
here <http://www.vtk.org/Wiki/VTK/Tutorials/Callbacks>   how this works. A
list of commands is found in the documentation of  vtkCommand
<http://www.vtk.org/doc/nightly/html/classvtkCommand.html#details>  .

How do you create grid lines? Similar to the  StructuredDataTypes example
<http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/StructuredDataTypes> 
?

I hope this was useful.

I don't get your question. Could you elaborate a bit more and maybe provide a
minimal example?

How do you map multiple spheres with one mapper? 

How about creating a separate highlight actor and map the highlighted object
with this actor?

Subject: [vtkusers] CMAKE error mt.exe failed to write the updated manifest
 to the resource file
Message-ID: <1451587177064-5735718.post@n5.nabble.com>

I am trying to update from VTK 6.2 to 6.3.  I installed the latest CMAKE
3.4.1.  I am using VS2010 64 bit compiler.  I tried disabling virus
protection. I previously build 6.2 successfully on Windows 7.  I have since
upgraded to Windows 10.

When I click the Configure button in the cmake interface, I get errors:

The C compiler identification is unknown... etc.

The CMakeOutput.log file contains the following error:

  
mt.exe : general error c101008d: Failed to write the updated manifest to the
resource of file ".\CompilerIdCXX.exe". The process cannot access the file 

because it is being used by another process.

Build FAILED.

Any suggestions?

Thanks,

hello vtkusers,
Happy new year!
I tried to google how to implement my own algorithm derived from vtkPloyDataAlgorithm, but no luck to find a very detailed example so far. Can anyone give me some relating information? Better an example from scratch with explanation as detailed as possible.
