Subject: [vtkusers] Migration problem vtk 5.8 - vtk 6.1
Message-ID: <6E9F1E5019D94267897964726438712A.MAI@softeco.it>

Hi,
my application has an executable and some dlls. Among them, there is one dll that used vtk 5.8 and now I'm doing the migration to the vtk 6.1.
 I'm using Visual Studio 2010 and my appliation is MFC-based.

In the properties of the dll using vtk, I obviously included the "Additional Include Directories" and "Additional Library" for the vtk header files and .lib files.
Moreover I added in the "Preprocessor definition" field of the C/C++ Property of the same dll, this value: vtkRenderingCore_INCLUDE="InitVtkObjFactory.h" and I added the file InitVtkObjFactory.h with this code: 

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingFreeType);
VTK_MODULE_INIT(vtkRenderingFreeTypeOpenGL);

When I close the application it crashes and in the call stack there is the last call on vtkCommonCore-6.1.dll.

Then, I removed the line inside the file InitVtkObjFactory.h related to the InteractionStyle as follows:

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkRenderingFreeType);
VTK_MODULE_INIT(vtkRenderingFreeTypeOpenGL);

and in this case, when the application starts, it shows a "warning" window from vtk in which is written:

Warning: In ..\..\..\..\..\src\Vtk\Rendering\Core\vtkInteractorStyleSwitchBase.cxx, line 43
vtkInteractorStyleSwitchBase (07EC7FB8): Warning: Link to vtkInteractionStyle for default style selection.

but when I close the application, this time it has no error or crashes. I'm using a vtkInteractorStyleTrackballCamera for my RenderWindow.

Any ideas? Is there anything wrong in the migration related to the new modules initialization?

Tks,
Lorenzo

The opacity function in the previous email is the only one I am creating.
Is there an error in that code then?

Thanks.

Also, I forgot to mention this, but if my code is modified to remove the
component on the opacity function so that it is:

  vtkSmartPointer<vtkPiecewiseFunction> compositeOpacity =
    vtkSmartPointer<vtkPiecewiseFunction>::New();
  compositeOpacity->AddPoint(0.0,0.0);
  compositeOpacity->AddPoint(1.0,1.0);
  compositeOpacity->AddPoint(255.0,1.0);
  volumeProperty->SetScalarOpacity(compositeOpacity);

Then the entire volume becomes not visible.

I see you are using vtk dlls. Were they built from the same compiler
as you use and the same configuration. You can't safely mix compilers
or use Releaase dlls in a debug application or debug dlls in a release
application.

Subject: [vtkusers] Extract pixel values inside a contour
Message-ID: <CAOZgs8fovyqnaUSwDJqa4rOmQk=6P-85o-C=+sHJvh9i8MABoQ@mail.gmail.com>

Hello all,

I have been working with border widget and I was able using the
borderrepresentation to extract the lower left and upper right points
and this was able to loop in the points covering the rectangle and
extract their pixel value using vtkImageData.
Now I have a contour widget where the user will pick an area ( can be
a circle or not) in a 2D slice, and I need to extract the pixel values
of pixels inside the contour. Any idea how to do it ? so far I was
able to extract the contour points but I don't know how to loop on
these points to get pixel values inside the contour points.

Thanks,
Dina.

Hi John, tks for your answer.
Yes I used the same compiler (VS2010) and I compiled vtk libraries as dlls.
Of course I included debug compiled vtk dlls in my application (debug mode) 
and release compiled vtk dlls in my release application.
It seems like it has problem to cleaning up the 
vtkInteractionStyleObjectFactory during the method 
"UnregisterAllFactories()" of the class "vtkCleanupObjectFactory".
Why it has this problem with the vtkInteractionStyle module?
Any ideas?
Tks,
Lorenzo

I would either:

1) turn off the optional InfovisParallel module.
 - it has seen little use in the last couple of years and hasn't been kept
up to date. This it is marked for deprecation now and will be removed after
the next release.

2) go back to boost 1_48
- I had that working on a vtk dashboard a year or so back

I have never tested the code in a scenario like this, although nothing
jumps out as an issue. Do you have header guards around this init
header to ensure it is just called once? It should be safe to call
many times, but it is possible something odd is happening there.

This is there to warn that no default interaction style will be used,
many old applications relied upon this being present and we wanted a
warning. It is just a warning, but it could be quite frustrating to
track down. It is unlikely to cause other side effects if you chose to
ignore it, but there is no way of silencing the warning.

If you set a style then all will work as expected. This looks like a
bug in the factory destruction, but I have not seen this in my testing
(I have also not built any VTK-based applications without using
CMake).

It is odd that it would break on such a simple module, with only a
single override. If you select a style you do not need that override,
but it would be nice to figure out what is going wrong here. I am not
aware of similar issues, do you have any more information on how/why
it is crashing? Is the object factory NULL for example?

Thanks,

Message-ID: <DUB130-W932E4675CC469DEF04067DE4070@phx.gbl>

Hi All,

I have been using VTK (version 5) for some time. I downloaded and built the source as detailed on the website, and then I was able to link to the libraries and include the header files manually as I usually do for third party libraries. Everything worked fine.

I'm now on a new system so I downloaded, configured and built VTK 6.1.0. It built fine and I installed it to the specified directory. However, I then found it impossible to manually link my VS project to the libraries. To get around this I tried using CMake to generate a Visual Studio project but nothing I try seems to work. A number of permutations each seem to give different errors, either include errors or linking errors. Some won't even configure with CMake!

Could someone please explain, in clear steps how one goes about building and linking to VTK?

Thanks very much,
Dan

(I'm not a novice but after three days trying to sort this out I'm out of ideas!)

Have you checked out the wiki page for configuring and building [1] ?  It
was written for VTK 6.1.0.

Could you post which step you're trying to accomplish, and the errors you
receive?  I think this will help us diagnose what's happening.

I suspect this is causing the problem.  Could you take it out of the
CMakeLists.txt file and just provide it at configure time via cmake-gui?

Hi Christopher,

Yes I have seen and read that page. The problem I am having is not building VTK itself, rather, building my own application which uses VTK. I have cobbled together a CMake file from scouring the VTK documentation / Google. It reads

cmake_minimum_required(VERSION 2.8.7)
project(Test)
set(VTK_DIR "C:/VTK-6.1.0/install")
find_package(VTK 6.1 REQUIRED NO_MODULE)
if(VTK_FOUND)
    message("found VTK. Version:" ${VTK_VERSION}. VTK_DIR: ${VTK_DIR})
endif()
include(${VTK_USE_FILE})
add_executable(Test test.cpp)
target_link_libraries(Test ${VTK_LIBRARIES})

It configures fine and generates a Visual Studio solution I can open, but when I try and build this it throws a linker error saying

"cannot open input file 'vtkalglib.lib'"

Interesting to note is that in my install folder (specified while building VTK) there is a .lib called 'vtkalglib-6.1.lib' but no 'vtkalglib.lib'. Also, even though I specified my VTK_DIR in the CMake it keeps showing the wrong directory in the CMake GUI and even if I change it, it swaps back when I click on configure.

Regards,
Dan

Hmm, just tried removing it. It doesn't make a difference. If I type the correct install directory into the GUI it just resets when I press 'configure'. If I type it an they just click 'generate' it still gives the error about 'vtkalglib.lib'.

Interesting.  Are you able to build any of the VTK examples [1] against
your current install?  Also, have you tried with a clean build tree of your
application?  It sounds like something is getting cached when it shouldn't
be.

It might help if I could have a look at your CMakeCache.txt, or if you
could take a screenshot of your cmake-gui before the "configure" step.

I tried building the example ReadImageData (http://www.vtk.org/Wiki/VTK/Examples/Cxx/IO/ReadImageData) since I want to use vtkImageData in my own app. Using the CMakeLists.txt from the page gives me an include error

Error    1    error C1083: Cannot open include file: 'vtkImageViewer2.h': No such file or directory    C:\Users\Dan\Documents\Visual Studio 2013\Projects\VTK_test\ReadImageData.cpp    5    1    ReadImageData

I have attached the CMakeCache.txt below. I notice it still says "/build" and not "/install" even though I changed it in the GUI / CMakeLists.txt.

Dan

Interesting.  Are you able to build any of the VTK examples [1] against your current install?  Also, have you tried with a clean build tree of your application?  It sounds like something is getting cached when it shouldn't be.

It might help if I could have a look at your CMakeCache.txt, or if you could take a screenshot of your cmake-gui before the "configure" step.

Hmm, just tried removing it. It doesn't make a difference. If I type the correct install directory into the GUI it just resets when I press 'configure'. If I type it an they just click 'generate' it still gives the error about 'vtkalglib.lib'.

Also, even though I specified my VTK_DIR in the CMake it keeps showing the wrong directory in the CMake GUI and even if I change it, it swaps back when I click on configure.


I suspect this is causing the problem.  Could you take it out of the CMakeLists.txt file and just provide it at configure time via cmake-gui?

Hi Christopher,

Yes I have seen and read that page. The problem I am having is not building VTK itself, rather, building my own application which uses VTK. I have cobbled together a CMake file from scouring the VTK documentation / Google. It reads



cmake_minimum_required(VERSION 2.8.7)
project(Test)
set(VTK_DIR "C:/VTK-6.1.0/install")
find_package(VTK 6.1 REQUIRED NO_MODULE)
if(VTK_FOUND)
    message("found VTK. Version:" ${VTK_VERSION}. VTK_DIR: ${VTK_DIR})


endif()
include(${VTK_USE_FILE})
add_executable(Test test.cpp)
target_link_libraries(Test ${VTK_LIBRARIES})

It configures fine and generates a Visual Studio solution I can open, but when I try and build this it throws a linker error saying



"cannot open input file 'vtkalglib.lib'"

Interesting to note is that in my install folder (specified while building VTK) there is a .lib called 'vtkalglib-6.1.lib' but no 'vtkalglib.lib'. Also, even though I specified my VTK_DIR in the CMake it keeps showing the wrong directory in the CMake GUI and even if I change it, it swaps back when I click on configure.

Dan

Have you checked out the wiki page for configuring and building [1] ?  It was written for VTK 6.1.0.  


Could you post which step you're trying to accomplish, and the errors you receive?  I think this will help us diagnose what's happening.

Hi All,

I have been using VTK (version 5) for some time. I downloaded and built the source as detailed on the website, and then I was able to link to the libraries and include the header files manually as I usually do for third party libraries. Everything worked fine.




I'm now on a new system so I downloaded, configured and built VTK 6.1.0. It built fine and I installed it to the specified directory. However, I then found it impossible to manually link my VS project to the libraries. To get around this I tried using CMake to generate a Visual Studio project but nothing I try seems to work. A number of permutations each seem to give different errors, either include errors or linking errors. Some won't even configure with CMake!




Could someone please explain, in clear steps how one goes about building and linking to VTK?

Thanks very much,
Dan

(I'm not a novice but after three days trying to sort this out I'm out of ideas!)

This should be set to the example source directory, which I would expect to
be named ReadImageData.  When building the example, there should be no need
to edit any CMakeLists.txt files.

Once you set up an empty, clean build directory, you should open up
cmake-gui.  "Where is the source code:" should point to the ReadImageData
example source code that you downloaded.  "Where to build the binaries:"
should point to the clean, empty directory you have made.  Then set VTK_DIR
to point to your VTK-6.1-install/lib/cmake/vtk-6.1 or build directory
(whichever contains VTKConfig.cmake), where you have built VTK.

VTK-6.1-install/lib/cmake/vtk-6.1 was the key! I set VTK_DIR to this subdirectory of my install folder (rather than the top level install folder) and it worked fine!

The help is much appreciated.

This should be set to the example source directory, which I would expect to be named ReadImageData.  When building the example, there should be no need to edit any CMakeLists.txt files.


Once you set up an empty, clean build directory, you should open up cmake-gui.  "Where is the source code:" should point to the ReadImageData example source code that you downloaded.  "Where to build the binaries:" should point to the clean, empty directory you have made.  Then set VTK_DIR to point to your VTK-6.1-install/lib/cmake/vtk-6.1 or build directory (whichever contains VTKConfig.cmake), where you have built VTK.

I have attached the CMakeCache.txt below. I notice it still says "/build" and not "/install" even though I changed it in the GUI / CMakeLists.txt.

Regards,
Dan

Interesting.  Are you able to build any of the VTK examples [1] against your current install?  Also, have you tried with a clean build tree of your application?  It sounds like something is getting cached when it shouldn't be.


It might help if I could have a look at your CMakeCache.txt, or if you could take a screenshot of your cmake-gui before the "configure" step.

Hmm, just tried removing it. It doesn't make a difference. If I type the correct install directory into the GUI it just resets when I press 'configure'. If I type it an they just click 'generate' it still gives the error about 'vtkalglib.lib'.

Also, even though I specified my VTK_DIR in the CMake it keeps showing the wrong directory in the CMake GUI and even if I change it, it swaps back when I click on configure.



I suspect this is causing the problem.  Could you take it out of the CMakeLists.txt file and just provide it at configure time via cmake-gui?

Hi Christopher,

Yes I have seen and read that page. The problem I am having is not building VTK itself, rather, building my own application which uses VTK. I have cobbled together a CMake file from scouring the VTK documentation / Google. It reads




cmake_minimum_required(VERSION 2.8.7)
project(Test)
set(VTK_DIR "C:/VTK-6.1.0/install")
find_package(VTK 6.1 REQUIRED NO_MODULE)
if(VTK_FOUND)
    message("found VTK. Version:" ${VTK_VERSION}. VTK_DIR: ${VTK_DIR})



endif()
include(${VTK_USE_FILE})
add_executable(Test test.cpp)
target_link_libraries(Test ${VTK_LIBRARIES})

It configures fine and generates a Visual Studio solution I can open, but when I try and build this it throws a linker error saying




"cannot open input file 'vtkalglib.lib'"

Interesting to note is that in my install folder (specified while building VTK) there is a .lib called 'vtkalglib-6.1.lib' but no 'vtkalglib.lib'. Also, even though I specified my VTK_DIR in the CMake it keeps showing the wrong directory in the CMake GUI and even if I change it, it swaps back when I click on configure.

Have you checked out the wiki page for configuring and building [1] ?  It was written for VTK 6.1.0.  



Could you post which step you're trying to accomplish, and the errors you receive?  I think this will help us diagnose what's happening.

Hi All,

I have been using VTK (version 5) for some time. I downloaded and built the source as detailed on the website, and then I was able to link to the libraries and include the header files manually as I usually do for third party libraries. Everything worked fine.





I'm now on a new system so I downloaded, configured and built VTK 6.1.0. It built fine and I installed it to the specified directory. However, I then found it impossible to manually link my VS project to the libraries. To get around this I tried using CMake to generate a Visual Studio project but nothing I try seems to work. A number of permutations each seem to give different errors, either include errors or linking errors. Some won't even configure with CMake!





Could someone please explain, in clear steps how one goes about building and linking to VTK?

Thanks very much,
Dan

(I'm not a novice but after three days trying to sort this out I'm out of ideas!)

Subject: [vtkusers] how  to write several scalars or vectors in ImageData
Message-ID: <23F07C37-B9EA-4984-8955-EDA3178170D6@gmail.com>

Hi all
I noticed that  in vtk one need to active a scalar/vector for the following filers. but I don?t know it works for output. I am using python for output my fields with several scalars as following:
image=vtkImageData()
image.SetDimensions(N1,N2,N3)
image.SetNumberOfScalarComponets(3)

image.GetPointData().AddArray(scalar1)
image.GetPointData().AddArray(scalar2)
image.GetPointData().AddArray(scalar3)

write=vtk.vtkXMLImageDataWriter()
writer.SetFileName(?test?)
writer.SetInput(image)
writer.Update()

but when I check the file with paraview, there are three scalars but the last two are over wrote by the first one. can any one tell me how to write several datas?




cheers

Subject: [vtkusers]  Border line color of vtkTextWidget
Message-ID: <CAOpQZmONfedUEbvyG+V3BFAprRH_+KPtd=KcaF0Y0fNWu9U3ow@mail.gmail.com>

I followed this example to add a vtkTextWidget:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/TextWidget

Everything worked fine. However, the rectangular border lines are white by
default. However, my render window has a white background color. So the
white textWidget border is not visible. I tried to change the border line
color into black with this statement:
textWidget->GetBorderRepresentation()->GetBorderProperty()->SetColor(0.,
0., 0.);

But I kept getting this error message:
error C2039: 'GetBorderRepresentation' : is not a member of 'vtkTextWidget'

FYI, I am using vtk 5.8 and included the proper headers such as:
#include <vtkTextWidget.h>
#include <vtkTextRepresentation.h>
#include <vtkCoordinate.h>
#include <vtkBorderRepresentation.h>
#include <vtkBorderWidget.h>

I'd like to have your assistance to change the color of vtkTextWidget
border lines.

Thank you for your help,
John

Hi Daniel,

On quick inspection this looks like a bug in vtkImageMapToColors not
handling the output info. You could file a bug here: http://vtk.org/Bug

Hi Goodwin,

thank you for your feedback. I?ll try again with a more recent snapshot, and if the problem persists, I?ll file a bug.

Hi Daniel,

On quick inspection this looks like a bug in vtkImageMapToColors not handling the output info. You could file a bug here: http://vtk.org/Bug

Hi everybody,

After porting a working application from vtk 5.x to vtk 6.1, I ran into some problems that I can?t solve by myself. Based on the error messages, I think though, it originates in the modified pipeline behavior of vtk 6.1 (admittedly I use an already aged snapshot from November 2013).

I tried to assemble a more or less minimal example to illustrate the problem. Basically I use the pipeline
vtkImageCanvasSource2D -> vtkImageMapToColors -> vtkImageViewer2.
If I visualize the canvas, without passing through the vtkImageMapToColors filter, everything works fine. If I pass through the vtkImageMapToColors filter, I get a blank render window and the error message :
?vtkTrivialProducer (00F15A08) : This data object does not contain the requested extent.?

I printed out the vtkInformation objects of the canvas? output port and the the vtkImageMapToColors? input port, and both outputs showed the correct extents for WHOLE_EXTENT and UPDATE_EXTENT, but wrong values for COMBINED_UPDATE_EXTENT. Moreover, canvas->GetOutput()->Print() gives also the right extents, whereas the output of the the vtkImageMapToColors shows that basically no meta information has been transmitted.

The complete code is below. Does anybody have a clue, what I am missing here ?

Thank you,
Daniel

Hi Marcus,
tks for your answer. Yes, I used the #pragma once directive inside my 
InitVtkObjFactory.h, so the file has the following code:

#pragma once

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingFreeType);
VTK_MODULE_INIT(vtkRenderingFreeTypeOpenGL);
VTK_MODULE_INIT(vtkRenderingOpenGL);

Debugging the code, during the factories creation I can see that the 
RegisteredFactories object defined in the file vtkObjectFactory.cxx, 
contains all the 4 factories. Looking inside the items value of that object 
I can see in the debug tooltip that each one is the related "factory" 
object. So for the InteractionStyleObjectFactory I can see the class name 
and the "mother" class vtkObjectBase.
Instead, during the exit of my appliation, when the UnRegisterAllFactories() 
method is called, I can't see anymore this value on the item related to the 
vtkInteractionStyleObjectFactory (I see only the vtkObjectBase), while for 
the remaining object factories I continue to see the class name.
At last, I fixed this behaviour for the debug 64bit version of my 
application calling the static method 
vtkObjectFactory::UnRegisterAllFactories(); just before calling the 
FreeLibrary of my dll. In this way, when this method is called by the 
vtkClenaupObjectFactory, the RegisteredFactories is already NULL.
It doesn't crash anymore in Debug 32/64 bit and Release 32 bit. It continues 
crashing in Release 64bit in the vtkCommonCore-6.1.dll.
I don't think that this could be a solution, could be a bug in the 
vtkObjectFactory?

Tks,
Lorenzo

The matlab interface was not updated during modularization for some reason
I do now know.

Filters/Matlab needs, for starters, a module.cmake to tell the VTK's
cmakescript about it. With that you will turn it on by turning on the
Module_vtkFiltersMatlab advanced cmake.

Hello,

Is there a class in vtk to extract a shell (external boundary) from some
unorganized points? The attached image explains the problem.

Thanks,

I don't believe there is anything like this built into VTK, but I wrote
some code for this as part of a project one time. You can read about the
technique here:

https://github.com/daviddoria/BoundingPolygon/blob/master/VTKJournal/BoundingPolygon.pdf
(click "view raw" to download)

And the code is here:
https://github.com/daviddoria/BoundingPolygon/blob/master/FindBoundaryPoints.cxx

(the root of the repository is https://github.com/daviddoria/BoundingPolygon
)

Good luck,

David

We kept the code but at the time had no way to build/verify and so a
new module was not created. This was contributed, it would be great to
bring it back. As Dave said we would need a module.cmake, and someone
with Matlab to build/test. This is one of the harder ones as it
requires a license for something we don't have generally available. It
may just work if you add a module.cmake with the appropriate
dependencies.

It certainly sounds odd, Visual Studio 2010 is pretty well tested. I
am not sure, but it sounds like an issue with the object factory or a
compiler issue. It is odd that you have a architecture/build specific
issue (32/64 bit on the same system) when calling it directly.

Sorry I can't be more help, I will see if I can reproduce this. I also
recently cleaned up a lot of the object factory code for
implementation modules a few weeks ago to ensure it is more consistent
across modules. Did you try a clean build (sounds like you probably
did with this level of experimentation).

Message-ID: <01c401cf962a$6120b500$23621f00$@radialogica.com>

Hi everyone,

I noticed that vtkImageStencilRaster has code like the following in
InsertLine and FillStencilData, for both the x and y directions:

if (x1 >= xmin)
     {
     r1 = vtkMath::Floor(x1) + 1;
     }
if (x2 < xmax)
     {
     r2 = vtkMath::Floor(x2);
     }

Correct me if I'm wrong, but it looks like the lower side is exclusive,
while the upper end is inclusive.  The upshot of this is that the only way
to stencil the first pixel is to have a line intersect the row on the
negative side of the first pixel (in the extents).  On the other hand, to
stencil the last pixel a line only need intersect anywhere past the
second-to-last pixel (in the extents).

Assuming that's true, it seems a bit asymmetric.  Is there any way to have
exclusive behavior on both ends?

Thanks,
Bryan

I have a working copy of matlab, and an interest in using this myself. So,
I'll take a crack at it...
Is anyone aware of the last commit that this feature worked? 
Any other tips, or some examples are very welcome as well.

Hi Bryan,

Do you mean inclusive on both ends?  Exclusive on both ends would
just make it worse...

The behavior of the rasterization is 100% intentional.  In order for
rasterization to work when there are adjacent areas that are being
rasterized, it must be exclusive on one end and inclusive on the
other end.  Otherwise, adjacent areas could end up with either a
gap between them or with an overlap.

The exclusitivity can be compensated for by subtracting a small
tolerance at the lower end or by using other tricks.

What is your use case?

Thanks for the quick reply, David.  You're right: I'm in need of inclusivity
on both ends.  I'm voxelizing contours using vtkPolyDataToImageStencil and I
want to ensure that the resulting stencil fully encapsulates the contours.
Are there any tricks to compensate that wouldn't require me to modify my
points directly?  I guess I could just dilate my result, but it would be
nice to have it as tight around the contours as possible.

 

Thanks,

Bryan

Have you tried adjusting the Tolerance on vtkPolyDataToImageStencil?
You can try setting it to a large value like 0.5, which gives half a pixel
in tolerance.  That should guarantee that the contour is fully inside of
the result.

All,
Ok, I got the adapter and engine compiling for matlab, and the vtk matlab
mex working. I've successfully used it on kubuntu 14.04, Matlab 8.3. I have
not tested it on windows. There were a few changes to the cxx code for the
vtk 6.0 pipeline, but the rest was CMake. 
I'd like to contribute it.

Thanks Marcus and David.

Jameson can you please help me with the cxx and cmake file you used ? I am
using matlab 8.3 on macbook pro. 
I tried reading :
http://www.vtk.org/Wiki/VTK/Module_Development
to help me create the module.cmake file Marcus and David wrote about, but I
am not exactly sure how to go about with it.

Thanks. .I got the solution already. i used the Spline filter output again to
another spline filter then my points are equally distributed. .

I rechecked the behavior with a more recent git snapshot as of yesterday; the behavior remains the same. So I filed a bug report with ID 0014838<http://vtk.org/Bug/view.php?id=14838>.

Hi Daniel,

On quick inspection this looks like a bug in vtkImageMapToColors not handling the output info. You could file a bug here: http://vtk.org/Bug

Hi everybody,

After porting a working application from vtk 5.x to vtk 6.1, I ran into some problems that I can?t solve by myself. Based on the error messages, I think though, it originates in the modified pipeline behavior of vtk 6.1 (admittedly I use an already aged snapshot from November 2013).

I tried to assemble a more or less minimal example to illustrate the problem. Basically I use the pipeline
vtkImageCanvasSource2D -> vtkImageMapToColors -> vtkImageViewer2.
If I visualize the canvas, without passing through the vtkImageMapToColors filter, everything works fine. If I pass through the vtkImageMapToColors filter, I get a blank render window and the error message :
?vtkTrivialProducer (00F15A08) : This data object does not contain the requested extent.?

I printed out the vtkInformation objects of the canvas? output port and the the vtkImageMapToColors? input port, and both outputs showed the correct extents for WHOLE_EXTENT and UPDATE_EXTENT, but wrong values for COMBINED_UPDATE_EXTENT. Moreover, canvas->GetOutput()->Print() gives also the right extents, whereas the output of the the vtkImageMapToColors shows that basically no meta information has been transmitted.

The complete code is below. Does anybody have a clue, what I am missing here ?

Thank you,
Daniel

 Hi Marcus,

yes of course I tried a clean build.

Anyway, I think that the problem is that I could fix it (although not in all the configurations/architecture) calling the vtkObjectFactory::UnRegisterAllFactories(); that it should be done by ?vtk itself?.

My application is a single-document MFC executable, that uses for the visualization in its main CWnd another dll including vtk libraries. 

As I think it isn?t correct to call that method, could be a bug in vtk? or in any properties of my visual studio projects?

Tks,

Lorenzo

It certainly sounds odd, Visual Studio 2010 is pretty well tested. I am not sure, but it sounds like an issue with the object factory or a compiler issue. It is odd that you have a architecture/build specific issue (32/64 bit on the same system) when calling it directly.



Sorry I can't be more help, I will see if I can reproduce this. I also recently cleaned up a lot of the object factory code for implementation modules a few weeks ago to ensure it is more consistent across modules. Did you try a clean build (sounds like you probably did with this level of experimentation).

Subject: [vtkusers] How to offscreen-render a specific field in VTK?
Message-ID: <CAOtam72MqOseVpj7sECPEw2kDBf+grPUrSU8mWTjtYd7rFfzyQ@mail.gmail.com>

Dear List,


I have a .VTK file, having UnstructuredGrid data, containing velocity field
and a scalar pressure field. Now I want to do the offscreen rendering.

Following the reader->mapper->actor->renderer pattern, I am able to render
the grid and export it to an image (using SetRepresentationToWireframe). (I
am using C++.)

Now I want to render, say the pressure field (p), google shows me that I
should use vtkLookupTable, and then SetLookupTable in the mapper. (Please
correct me if I am wrong.) But I have no success, the result image is white
blank. My questions are:

   1. Which reader should I use? Should I continue to use the
   vtkUnstructuredGridReader?
   2. How to get the specific scalar/vector variable in lookuptable?

Here is the part of the code related to my question.

// ------------// Create a reader: Read the file// ------------
vtkSmartPointer<vtkUnstructuredGridReader> reader =
    vtkSmartPointer<vtkUnstructuredGridReader>::New();//
vtkSmartPointer<vtkPolyDataReader> reader =//
vtkSmartPointer<vtkPolyDataReader>::New();//
vtkSmartPointer<vtkDataSetReader> reader =//
vtkSmartPointer<vtkDataSetReader>::New();
reader->SetFileName(inputFilename.c_str());
reader->Update();

vtkSmartPointer<vtkLookupTable> lut =
    vtkSmartPointer<vtkLookupTable>::New();
lut->SetNumberOfTableValues(1);
lut->Build();
// ------------// Create a mapper// ------------//
vtkSmartPointer<vtkPolyDataMapper> mapper = //
vtkSmartPointer<vtkPolyDataMapper>::New();
vtkSmartPointer<vtkDataSetMapper> mapper =
    vtkSmartPointer<vtkDataSetMapper>::New();
mapper->SetInputConnection(reader->GetOutputPort());//
mapper->SetScalarRange(scalarRange[0], scalarRange[1]);
mapper->SetScalarModeToUseCellData();
mapper->SetLookupTable(lut);
// ------------// Create a actor// ------------
vtkSmartPointer<vtkActor> actor =
    vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
actor->GetProperty()->SetColor(0,0,0);
actor->GetProperty()->SetRepresentationToWireframe();//
actor->GetProperty()->SetRepresentationToSurface();

PS: Any insight from python or TCL is also welcome.


Thanks

To be totally clear I agree, I still need a minimal example I can
reproduce in order to fix it.

Yes, and figuring out which one is the challenge. If you try removing
the init from the Visual Studio properties, and simply include it in
your application code does this help? I have not seen this method of
injecting code, it should work but I am not aware of others using it.
I never work with Visual Studio projects without using CMake to
generate them, but the object factory code is pretty robust.

To be clear this is not expected behavior, but it is unclear to me if
it is an issue with your Visual Studio build files or in VTK's C++
code.

Hi Daniel,

I am happy to report that this is not a bug in VTK. It is a bug in the
example instead. I am happy because I don't have to fix a bug in my code :-)

Take a look at this document:
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Replacement_of_SetInput

It explains that SetInputData() does not set a pipeline connection. When
you use it, you need to make sure that the pipeline that produce the data
is manually updated. So adding a
color->Update();
before rendering happens will fix the issue.

If your intention is to setup a pipeline connection such that any change in
filter parameters are automatically reflected in the viewer, use this
instead:
imageViewer->SetInputConnection(color->GetOutputPort());

Best,
-berk

Message-ID: <1404408073823.4791@uwyo.edu>

Dear:


I have wrote a simulator using BGL.

Now, I wish to write it to VTK-PGBL mode.


Using VTK 6.2, I have difficulty to turn on "VTK_USE_BOOST".

How should I proceed this?

Thank you for advices.

Does anyone have the files Thomas used in his examples in [1]?  In those
examples, he shows two renders from VTK, but the code he has posted doesn't
include any render windows.  I made my own renderwindows, etc to display the
data that's passed to the vtkmatlabadapter, the data is displayed correctly,
but when I close the window it also exits matlab (cleanly).  I was hopping
he had some code he used to prevent this...

Betreff: Re: [vtkusers] Extent / Pipeline Problem with vtk 6.1

Hi Daniel,

I am happy to report that this is not a bug in VTK. It is a bug in the example instead. I am happy because I don't have to fix a bug in my code :-)

Take a look at this document:
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Replacement_of_SetInput

It explains that SetInputData() does not set a pipeline connection. When you use it, you need to make sure that the pipeline that produce the data is manually updated. So adding a
color->Update();
before rendering happens will fix the issue.

If your intention is to setup a pipeline connection such that any change in filter parameters are automatically reflected in the viewer, use this instead:
imageViewer->SetInputConnection(color->GetOutputPort());

Best,
-berk

On quick inspection this looks like a bug in vtkImageMapToColors not handling the output info. You could file a bug here: http://vtk.org/Bug

Hi everybody,

After porting a working application from vtk 5.x to vtk 6.1, I ran into some problems that I can?t solve by myself. Based on the error messages, I think though, it originates in the modified pipeline behavior of vtk 6.1 (admittedly I use an already aged snapshot from November 2013).

I tried to assemble a more or less minimal example to illustrate the problem. Basically I use the pipeline
vtkImageCanvasSource2D -> vtkImageMapToColors -> vtkImageViewer2.
If I visualize the canvas, without passing through the vtkImageMapToColors filter, everything works fine. If I pass through the vtkImageMapToColors filter, I get a blank render window and the error message :
?vtkTrivialProducer (00F15A08) : This data object does not contain the requested extent.?

I printed out the vtkInformation objects of the canvas? output port and the the vtkImageMapToColors? input port, and both outputs showed the correct extents for WHOLE_EXTENT and UPDATE_EXTENT, but wrong values for COMBINED_UPDATE_EXTENT. Moreover, canvas->GetOutput()->Print() gives also the right extents, whereas the output of the the vtkImageMapToColors shows that basically no meta information has been transmitted.

The complete code is below. Does anybody have a clue, what I am missing here ?

Thank you,
Daniel

Thanks Jameson. I will take a look. I have manage to compile it somehow

Were you able to run the  example below from  
http://www.kitware.com/media/html/MATLABAndGNURIntegrationWithVTK.html ?
I am getting this output with nothing shown in the rendering window:
 ALGORITHM_AFTER_FORWARD: 1
  FORWARD_DIRECTION: 0
  FROM_OUTPUT_PORT: 0

I believe the "Normals" in   ef->PutArray("Normals", "N") might be passing 0
to the function.


#include ?vtkMatlabEngineFilter.h?
#include ?vtkSphereSource.h?
#include ?vtkWarpVector.h?

int main()
{

vtkSmartPointer<vtkSphereSource> ss =
vtkSmartPointer<vtkSphereSource>::New();
    vtkSmartPointer<vtkMatlabEngineFilter> ef
=vtkSmartPointer<vtkMatlabEngineFilter>::New();
    vtkSmartPointer<vtkWarpVector> wv =
vtkSmartPointer<vtkWarpVector>::New();
    
    ss->SetThetaResolution(100);
    ss->SetPhiResolution(100);
    
      ef->SetInputConnection(ss->GetOutputPort());
     vtkSmartPointer<vtkPolyData> polydata =
vtkSmartPointer<vtkPolyData>::New();
    
     ef->PutArray("Normals", "N");
     
     ef->SetMatlabScript(
     "rv = randi([-1,1],size(N,1),1);\
     N(:,1) = N(:,1).*rv;\
     N(:,2) = N(:,2).*rv;\
     N(:,3) = N(:,3).*rv;");
     
     ef->GetArray("N", "N");
     
     wv->SetInputData(ef->GetOutput());
      wv->Update();
     

     vtkSmartPointer<vtkPolyDataMapper> Mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
  Mapper->SetInputData(wv->GetPolyDataOutput());
     vtkSmartPointer<vtkActor> Actor = vtkSmartPointer<vtkActor>::New();
     Actor->SetMapper(Mapper);
}

Hi,

Unfortunately there may be not the form for cylindrical coordinate
system in vtk file format. But you can load your cylindrical data as
vtkRectilinearDataSet or vtkStructuredGrid data set and then transform them
to Cartecian coordinate system using vtkCylindricalTransform.

Thanks,
Yoshimi

Hi I need a vtkCommand which can emit signal when camera or focal point 
position change
is there any vtkCommand like I need.

Thank you

Not just for those changes, but you can get the modified event. Here
is an example:

Subject: [vtkusers] Need suggestions about choosing suitable pipeline and
	data type
Message-ID: <1404661157218-5727762.post@n5.nabble.com>

Hi, 
  I am writing a application to manipulate some VOIs. VTK 6.1.0 is used 
and compiled by cmake under VS2012. The application is developed under
python. 

The procedure of this application is :
1. read DICOM files
2. extract some volume of interest
3. pick one of VOI and move in renderer to suitable position
4. mirror VOI
5. perform boolean operation on two of VOIs

The current progress is that I can read DICOM files (vtkDICOMReader) into
vtkImageData. VOI can be selected and extracted by vtkBoxWidget2 and 
vtkExtractVOI. The result vtkImageData is tranform to vtkPolyData by 
vtkMarchingCubes. The mirror VOI function is completed by
vtkReflectionFilter.

The problem is met when performing boolean operation on two VOIs by using
vtkBooleanOperationPolyDataFilter, it crushed when Update() is
called. 

After reading some posts in this maillist. I think this problem maybe caused
by
something wrong on the constructed PolyData. 

Then I am trying not to transform vtkImageData to vtkPolyData but using 
volume rendering directly. By now, it works fine in display and extract VOI. 

But when moving actor in renderer by vtkInteractorStyleTrackballActor. Once
I 
moved an VOI to another position. After I change back to
vtkInteractorStyleTrackballCamera
and change cameras position, the VOIs behavior is not the same as PolyData
actor.
It seems rotate to each rotation center. 

Any suggestion about how to processing these data?

Thanks

Subject: [vtkusers] Unable to run BFS on graph!
Message-ID: <1404685956336-5727763.post@n5.nabble.com>

Hey guys I have been stuck with this for a while now! . 

1) I converted polydata to graph using
https://github.com/daviddoria/VTK-GraphConversions

2) I have displayed(visualised) the graph and converted it back to mesh
again and it is just fine 

3) However, I am trying to run Breadth First Search on a chosen vertex in
the resulting graph(to find a closed path along the polydata, for
segmentation purposes) but it only traverses through 10-15 vertices after
which it stops.

Heres my code for the traversal, can someone PLEASE! let me know what
mistake i have made( or any other solution) :

	vtkIdType root =0;
   	
    vtkSmartPointer<vtkBoostBreadthFirstSearchTree> bfsTree = 
    vtkSmartPointer<vtkBoostBreadthFirstSearchTree>::New();
  bfsTree->SetOriginVertex(root);
  bfsTree->SetInput(polyDataToGraphFilter->GetOutput());
  bfsTree->Update();

  vtkSmartPointer<vtkBoostBreadthFirstSearch> bfs = 
    vtkSmartPointer<vtkBoostBreadthFirstSearch>::New();
  bfs->SetOriginVertex(root);
  bfs->SetInput(polyDataToGraphFilter->GetOutput());
  bfs->Update();
 

  vtkSmartPointer<vtkTreeBFSIterator> bfsIterator = 
		vtkSmartPointer<vtkTreeBFSIterator>::New();
	bfsIterator->SetStartVertex(root);
	bfsIterator->SetTree(bfsTree->GetOutput());

	//traverse the tree in a breadth first fashion
	while(bfsIterator->HasNext())
	{
		
		vtkIdType nextVertex = bfsIterator->Next();
	
		std::cout << "Next vertex: " << nextVertex  <<std::endl;

	}



THANKS!!! ( I have attached an image of the resulting graph)

Hi Saeed,

Please keep the discussion on the mailing list because I am not a VTK
specialist.

I think cylindrical transformation will do if you confirm that your input
coordinate sequence is (r,theta,z) and write code similar to the following:

    // Get all data from the file
    vtkSmartPointer<vtkGenericDataObjectReader> reader =
        vtkSmartPointer<vtkGenericDataObjectReader>::New();
    reader->SetFileName(inputFilename.c_str());
    reader->Update();

    // convert cylindrical to Cartesian coordinate system
    vtkSmartPointer<vtkCylindricalTransform> cylTrans =
        vtkSmartPointer<vtkCylindricalTransform>::New();

    vtkSmartPointer<vtkTransformFilter> cylTransFilter =
        vtkSmartPointer<vtkTransformFilter>::New();
    cylTransFilter->SetInputData(reader->GetOutput());
    cylTransFilter->SetTransform(cylTrans);
    cylTransFilter->Update();

However there is a possibility that the transformed results will have a
lack of  the resolution in the circumferential direction. In that case, you
may need to subdivide in theta direction on input data preliminarily.

Regards,
yoshimi

i'm learning how to use VTK. So i got this example code :

http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/EmbedPointsIntoVolume

Which generates a volume from a set of points stored in a .vti file.

I'm trying to make this work with a set of points i imput manually in code,
just to see how this works... but the program ALWAYS just generates a
cube... am i missing something?

Thanks a lot in advance!

Here is my code:

	set points
Message-ID: <CAAzeLU2yND09FG5M61cgiMvu5JV=TKP0XP5rKp8V=xV9RhAETg@mail.gmail.com>

Dear all,

I am trying to implement a distance widget with a previously set
representation (I want to give the points programatically and not by
clicking on the screen). I tried the following code and the distance
computed is correct, but the widget shows a line joining two points that
are not the ones I typed in the code.

In the attached image, the blue lines joins the correct points, the green
one corresponds to the widget.

Thanks,
Hector

    vtkSmartPointer<vtkDistanceWidget> distanceWidget =
    vtkSmartPointer<vtkDistanceWidget>::New();
    distanceWidget->SetInteractor(renderWindowInteractor);
    distanceWidget->CreateDefaultRepresentation();
    vtkDistanceRepresentation * distRep =
distanceWidget->GetDistanceRepresentation();
    distRep->SetPoint1WorldPosition(PointInit);
    distRep->SetPoint2WorldPosition(PointEnd);
    distanceWidget->SetWidgetStateToManipulate();

Hi Marcus,
please find attached a simple test project I made extracting and simplifying 
as much as I could my original software application.
Inside the file Test_VtkMFC.zip there is a README.txt file explaining how to 
build and reproduce the bug.
It is a templated MFC-based application from VS2010 (single doc and Office 
2007 Ribbon style).
Let me know if it crashes in Release 64 bit and if you can see where it is 
the problem (e.g. in one of my project settings).
Tks,

Lorenzo

To be totally clear I agree, I still need a minimal example I can
reproduce in order to fix it.

Yes, and figuring out which one is the challenge. If you try removing
the init from the Visual Studio properties, and simply include it in
your application code does this help? I have not seen this method of
injecting code, it should work but I am not aware of others using it.
I never work with Visual Studio projects without using CMake to
generate them, but the object factory code is pretty robust.

To be clear this is not expected behavior, but it is unclear to me if
it is an issue with your Visual Studio build files or in VTK's C++
code.

Subject: [vtkusers] Update position of multiple render windows
Message-ID: <1404749767214-5727775.post@n5.nabble.com>

(I'm copy/pasting this from my StackOverflow post since it's pretty
well-developed so far. Forgive me if that's an offense)

I'm running into a bit of a problem when trying to run multiple render
windows in a Python VTK application I'm writing. The application is an
attempt to render a 3D model in two separate views for a stereo application
(i.e. Left render and right render), but I'm having an issue with updating
the cameras of each window simultaneously. I currently have two nearly
identical pipelines set up, each with its own vtkCamera, vtkRenderWindow,
vtkRenderer, and vtkRenderWindowInteractor, the only difference being that
the right camera is positionally shifted 30 units along the X axis.

Each of the render window interactors is being updated via the
vtkRenderWindowInteractor.AddObserver() method that calls a simple function
to reset the cameras to their original positions and orientations. The
biggest issue is that this only seems to occur on one window at a time,
specifically the window in focus at the time. It's as if the interactor's
timer just shuts off once the interactor loses focus. In addition, when I
hold down the mouse (And thus move the camera around), the rendered image
begins to 'drift', resetting to a less and less correct position even though
I have hardcoded the coordinates into the function.

Obviously I'm very new to VTK, and much of what goes on is fairly confusing
as so much is hidden in the backend, so it would be amazing to acquire some
assistance on the matter. My code is below. Thanks guys!

EDIT 1: I modified the code to accept user input for the
self.leftCam.SetPosition() call within the vtkGyroCallback.execute() method
(Thus replacing the hardcoded "10, 40, 100" parameters with three input
variables) then piped the output of a script that simply displayed three
random values into my main program. What this should have accomplished was
having a render window that would constantly change position. Instead,
nothing happens until I click on the screen, at which point the expected
functionality begins. The whole time, timer events are still firing and
inputs are still being accepted, yet the cameras refuse to update until a
mouse event occurs within the scope of their window. What is the deal?

EDIT 2 I've dug around some more and found that within the
vtkObject::InvokeEvent() method that is called within every interaction
event there is a focus loop that overrides all observers that do not pertain
to the object in focus. I'm going to investigate if there is a way to remove
focus so that it will instead bypass this focus loop and go to the unfocused
loop that handles non focused objects.

Subject: [vtkusers] GLSL Shader on a vtkActor (VTK 6.1 and Qt 5.2.1)
Message-ID: <1404749884394-5727776.post@n5.nabble.com>

Hi all, 

I have an assembly with different actors into a vtkRenderWindow. 

I load a shader with the class vtkShader2, and create the program with
vtkShaderProgram2, all ok with this. After that, i wanted to attach the
shader to the actors (i'm going to use different shaders, depending on the
actors). The problem is i didn't find examples or documentation to do this
and i'm not capable to use the classes for the shaders correctly. 

I searched into the class vtkOpenGLProperty to set the vtkShaderProgram2
with the method "SetPropProgram" and i set the property of the actors with
that one, but vtk shows me a warning window with a conflict between the
default shaders and mine (total 4 shaders, 2 vertex and 2 fragment). 

Can someone help me? Thanks in advance!!

Hi all,

thanks to Yoshimi that gave me some ideas about transferring data from
cylindrical Cartesian.
I am pretty new in paraview and specially in scripting in it.
this is the script that he gave me:
// Get all data from the file
    vtkSmartPointer<vtkGenericDataObjectReader> reader =
        vtkSmartPointer<vtkGenericDataObjectReader>::New();
    reader->SetFileName(inputFilename.c_str());

    // convert cylindrical to Cartesian coordinate system

I would appreciate  if somebody help me to understand this script better

Subject: [vtkusers] Issue with ParaView 4.1.0
Message-ID: <CAJC7CwaGGstVFHmxR7OobxXUCosBGW8LBJyZ0eMxOhQWZiU81A@mail.gmail.com>

Apologies if this is going to the wrong forum.

I'm currently trying to compare two different mesh solution output files in
ParaView 4.1.0 Linux64bit(Ubuntu 12.04 LTS). I'm getting an strange error
that doesn't make much sense and I think may have something to do with my
settings.

I have a data range for the following variables to be rendered.

File_1:

disp_Magnitude: [0,.100]
disp_x: [-0.001,0.001]
disp_y: [-2e-5, 2e-5]
disp_z: [-0.10, 2e-6]

File_2:

disp_Magnitude: [0,.100]
disp_x: [-0.002,0.002]
disp_y: [-8e-6,0.001]
disp_z: [-0.10,0.0110]

File_2 seems to be able to be rendered fine in ParaView but File_1 is
giving me troubles. It says "Data range too small to render" in the corner
Mapping Data section. I have another program(a simple gui with my solver)
that can open these types of files(Exodus II .e format) and all is fine(no
errors, the data is there) for both File_1 and File_2. Does anyone know
what might be going on here?

A couple things I've tried

-For File_1 I tried to set a log scale for the color map transfer function
and got this error:

" Warning: Range [0,0.100038] invalid for log scaling. Changing to
[0.0100038,0.100038]."

So I know that the program sees the correct data range or does it?

-I've also looked in the information tab for my exodus object in ParaView.
It says my data ranges for all of the variables are type double [0,0] but
this is absolutely wrong since I can open the same file in my gui and view
the mesh with the correct data ranges for each of these variables. I also
think the error for log scale conflicts this statement. Why does the
information tab say [0,0] but log scale reads a range of [0,0.1]?

-If I open File_1 and then open File_2 in this order I get the same error
for File_2 that I get for File_1. Then if I change my disp_Mag variable to
disp_X the problem ceases for File_2

Also I'm sure all of my settings are set to DEFAULT since I haven't changed
them at all.

Thanks for the help

Hi !

I am trying to get a 4x4 transform Matrix in order to use it on contours
made on a vtkImageSlice.
I used two orientation vectors, calculate a third on with a cross operation,
then made a matrix with them .

v1x,v2x,vx,0
v1y,v2y,vy,0
v1z,v2z,vz,0
0,0,0,1

Did I thought well or ?

Subject: [vtkusers]  About vtkImageReslice interpolation
Message-ID: <CAC9gB0BiRMcjv+qPZX3D6LU5-bSrRJ5qF=V=zodGn7rECM=q+g@mail.gmail.com>

Hi All,

We use vtkImageResample/vtkImageReslice (from vtk 5.8.1) quite a lot here,
and I've noticed a strange behavior.

If we down sample a volume by a factor of 2 in all 3 directions, the output
image will be the exact same if we use a nearest neighborhood, linear or
cubic interpolation. There seems to be no interpolation at all if the
reduction factor is a power of two.
If the reduction factor is set to 2.00001, the interpolation is performed
correctly when asked for linear or cubic.

Is this an intended behavior ?

After some debugging :
In the file vtkImageReslice.cxx, method vtkTricubicInterpCoeffs (line 1503)
 with a power of 2 factor we always fall back to the part with the comment
// no interpolation (line 1510), but I don't understand why.

And last question : there is a new vtkImageResize that was introduced in
vtk 5.10, will the behavior be the same ?

Thanks for your help

-Simon

Hi Simon,

If you are downsampling the image by simply changing the output
spacing, without introducing a shift in the positions of the samples,
then downsampling is a decimation operation (i.e. downsampling
by a factor of three is the same as taking every 3rd voxel).   This is
true whether you use linear, cubic, or NN interpolation.  The code
optimizes such decimations by turning off the interpolation.

In VTK, the Origin is at the center of the first voxel, so a straightforward
downsampling places centers each output voxel at exactly the position
of one of the input voxels, which is why downsampling becomes
decimation.  To avoid this, you must shift the output Origin relative to
the input Origin.

The new vtkImageResize filter has BorderOn()/BorderOff() methods
to control this behavior.  If Border is Off (the default) the behavior is
like vtkImageReslice.  If Border in On, then the output origin is
automatically shifted relative to the input origin so that the shrink
factors are applied relative to the outer corner of the first voxel,
rather than relative to the center of the first voxel.

I'm not sure if that was a clear explanation, so let me know if you
still have questions.

  - David

Hi David,

Thanks for your explanation, very clear as usual !
However, this look like a bug to me, at least from the user point of view.
When the linear or cubic interpolation is activated, the user expect to get
an interpolation even for simple case where is could be assimilated to a
decimation.

Will try out your new vtkImageResize that seems promising !

Thanks
Simon

How would the user even know?  We're talking about cases where the output
would be exactly the same whether or not interpolation is performed.

Hi Mark,

I know it's much later, but is there any chance you ever figured this out? I
am also looking to apply the vtkWarpLens to a vtkCamera, specifically to
perform a barrel distortion. If there's any way you can help, that would be
great.

Thanks,
Alex

Subject: [vtkusers] Defining OpenGL shader with VTK 6.1 and Python 2.7
Message-ID: <1404838506315-5727797.post@n5.nabble.com>

I am trying to use OpenGL shaders to apply a barrel deformation to a VTK
actor. The end goal is to adapt  febret's shaders
<https://github.com/omega-hub/rift/blob/master/OVRShaders.h>   for the
Oculus Rift. 

The documentation states that this should be done using vtkShader2, since
XML and cg shaders have been depricated in VTK 6.1. However, I am finding it
difficult to do this with using Python 2.7.

Specifically, transposing the  VTK test code
<http://vtk.org/gitweb?p=VTK.git;a=blob;f=Charts/Core/Testing/Cxx/TestGLSL.cxx>  
into Python hits a snag because vtkShader2 does not appear to be available
in the vtk module.

I've spent a few days trying to brute-force my way through this, but haven't
gotten anywhere, and would really appreciate any advice.

Questions:
 - Can vtkShader2 be accessed via a Python wrapper?
 - Is is possible to use user-defined OpenGL shaders in VTK 6.1 via Python?

In advance, thank you for your help.
Alex

Subject: [vtkusers] Raw pointer returned as a string in Python
Message-ID: <CAG7FRHL=OW_OtcpNqcX5XS+hJn6-x0vJBVQMQhyL_yqzCnv6cg@mail.gmail.com>

Hi all,

I am having a little issue concerning a function in Python that returns
what seems like a pointer as a string.

>> visPts = vtk.vtkSelectVisiblePoints()
>> visPts.SetInputData(polyData)
>> visPts.SetRenderer(ren)
>> zbuff = visPts.Initialize(True)
>> print zbuff
>> print type(zbuff)

and it prints:
_000000000dc90040_void_p
<type 'str'>

?I understand that `vtkSelectVisiblePoints::vtInitialize(bool)'? returns a
raw pointer (float*) which I believe cannot directly be exposed to Python,
but is there a way to pass it to
`vtkSelectVisiblePoints::IsPointOccluded(const double[3], connst float*
zBuffer)' in Python somehow? Or is it just a limitation of the Python
interface?

Thanks a lot for your help!

?Guillaume?

Hi Guillaume,

I'm surprised that the "float *Initialize()" method is even wrapped.
Generally, such methods only return a "_xxxx_void_p" string if
they return "void *".

Anyway, in VTK 6.2, the IsPointOccluded() method is wrapped and
you will be able to call it after you turn the "zBuffer" into a python
container of some sort.  I'd recommend using a numpy array as the
container for the sake of efficiency.

So, what you will have to do is find a way of creating a numpy float
array from the hexadecimal address in the string.  I have no idea
how to do it, but I'm sure there is a way.

Note, however, that the docs for vtkSelectVisiblePoints::Initialize()
say that it returns a new pointer that must be deleted.  In other words,
you will also have to find some way of deleting the pointer from
Python or else you will end up with a memory leak.

Thanks a lot David for your directions.

I managed to accomplish what you said by doing:

>> zbuff_str = visPts.Initialize(True)
>> address = int(zbuff_str[1:17], 16)
>> w, h = renderWin.GetSize()
>> size = w*h
>> FLOATP = ctypes.c_float * size
>> zbuff_buff = FLOATP.from_address(address)
>> # will do a copy here, `np.frombuffer(zbuff_buff)' would be more adequat
>> zbuff = np.fromiter(zbuff_buff, dtype=np.float, count=size)
>> ...
>> visPts.IsPointOccluded(point, zbuff)

By using numpy.frombuffer I get a crash in `IsPointOccluded'. I didn't get
deeper into why this would happen, but this is ok for my use to copy the
whole thing.

It is a simple prototype so I don't mind the leak for now :)

Thanks again,

Guillaume

Subject: [vtkusers] How to rotate the outline of the vtkImplicitPlaneWidget2
	?
Message-ID: <CAGye1gDDnmDnKoQkWax9UmcOdsHF9OGBPEgj-8D442yULmvERA@mail.gmail.com>

Hi,
I am designing an interactive visualization program, in which users can
interactively rotate the volumetric data. The users are supposed to rotate
the data directly, instead of changing the camera position to simulate the
rotation.

In this program, I have three things so far: a box outline of the
volumetric data, a direct volume rendering of the data, and
a vtkImplicitPlaneWidget2 to clip the data. To implement the rotation, I
apply a transformation by calling the "SetUserTransform()" function of the
vtkActor and vtkVolume to transform the data outline and the volume
rendering, respectively. However, I could not find such an option of
"SetUserTransform()" for vtkImplicitPlaneWidget2 or
vtkImplicitPlaneRepresentation.

Is there a method I can use to rotate the outline of the
vtkImplicitPlaneWidget2 and make it consistent with the rotation of my data
ouline? or I should have transformed the data outline and volume rendering
in a different way?

Thanks in advance,

Xin

vtkEarthSource creates a polydata, so you should be able to set the color
like this:

actor->GetProperty()->SetColor(1.0, 0.0, 0.0); //(R,G,B)

Hi Marcus,
I tried to semplify the code I sent in my last mail.
Now the class exported by my .dll doesn't do anything. I left only the "auto 
init" of the modules inside the file initVtkObjFactory.h.
Now it gives memory leaks in all the debug architectures, but still crashes 
only in Release x64 when I close the application.
I hope this example code can be clear for you.
Tks,
Lorenzo

Hi Marcus,
please find attached a simple test project I made extracting and simplifying

Inside the file Test_VtkMFC.zip there is a README.txt file explaining how to

It is a templated MFC-based application from VS2010 (single doc and Office

Let me know if it crashes in Release 64 bit and if you can see where it is

Yes, and figuring out which one is the challenge. If you try removing
the init from the Visual Studio properties, and simply include it in
your application code does this help? I have not seen this method of
injecting code, it should work but I am not aware of others using it.
I never work with Visual Studio projects without using CMake to
generate them, but the object factory code is pretty robust.

To be clear this is not expected behavior, but it is unclear to me if
it is an issue with your Visual Studio build files or in VTK's C++

using vtkcelllocator. from that  i will get the cell id. i can able to find

of the point as the cell id normal.

The thing is that some times if i pass the points the cellid is getting

Do Anybody have the better solution for my problem to find out the normal of

In this case it doesn't crash anymore, but I can't use the object factory in

Message-ID: <c81bc5f58e7a06f77833df4e2f04a745@mufradat.com>

Hello Everyone,
I am using vtkImageReslice in connection with vtkImageViewer2 to view 2D 
slice of a 3d Dicomm image. Everything works great, Also when I try to 
change the slice thickness by doing :
m_reslice->SetOutputDimensionality(2);
m_reslice->SetBackgroundLevel(-1000);
m_reslice->SetInterpolationModeToCubic();
  	m_reslice->SetSlabModeToMean();
m_reslice->SetSlabNumberOfSlices(m_thickness);
the code can be found here:
https://github.com/CardiacImagingCharite/CardiacPerfusion/blob/directions/vtkwidgets/multiplanarreformatwidget.cpp

Everything is working as expected. The only problem I face appears when 
I compile VTK (5.10.1) in release mode.

In release mode, the program works fine, until i use a GUI slicer to 
change the value of m_thickness at this point i get a black screen in 
the viewer widget which does not happen if VTK was compiled in Debug 
mode.

Please help me as I have been fighting with this for several weeks now 
and I have ran out of ideas after played a lot with VTK cmake flags and 
even installed a graphic card (Nvidia).


Best Regards,
Ahmed

Lorenzo,

Apologies, really busy right now. Why don't you think you can use the
object factory in Display3d.dll if you move the init to the .exe? The
intended use of the macro was to be compiled into the application
executable, the object factory initialization is process wide we just
need the object factories to be initialized before any objects are
created in a given process.

I will try to find some time to look at why it is failing in the dll
init method, but I would advise you to initialize the object factories
from the executable code if you possibly can.

Hi Marcus,
great news I fixed it! :)
I moved the initVtkObjFactory.h from my .dll to my executable project as I 
already told you, but instead of calling it using the preprocessor 
properties (in this way the ::New() inside my .dll returns always NULL), I 
included that file in the "stdafx.h" of the .exe project.
In this way it doesn't crash anymore and I can use without problems the vtk 
objects in my dll.
The reason because I didn't use untile now the vtk init in my .exe project 
was that I didn't want to include vtk libraries dependencies in this 
project, but only in the project (dll) that uses them. In this way, a user 
is quite "forced" to add vtk dependencies in the .exe project even if it 
doesn't really need them.
However, tks a lot for your support.

Regards,
Lorenzo

Subject: [vtkusers] Pass value from vtkInteractorStyle to local variable?
Message-ID: <1405085909122-5727826.post@n5.nabble.com>

All--

I'd like to understand the best practice for passing a variable obtained in
an interactor to a local variable, such that it can be used after the render
window is closed (in my case: open a window, obtain pixel coordinates from
mouse click, close window, then use the pixel coordinates later on in the
program).  I can get the functionality I want by creating a InteractorStyle
class (inheriting from vtkInteractorStyleImage, pasted at the bottom of this
e-mail) that saves the pixel coordinates to a global variable pointPosition
OnLeftButtonUp, then closes the window OnRightButtonUp.  However, I'm
nervous that coding a global variable name into a class is not very
maintainable, and thought there was likely a better way to do it.  What is
the best practice in this case?

Sorry if this is more of a c++ question and less of a VTK question--I've
been learning c++/vtk/itk in tandem with one another, and am sometimes
unclear when one ends and the other begins.

Best, and thanks,

--Davis

// Create a class inheriting from vtkInteractorStyleImage
class dvInteractorStyleSelectPoint : public vtkInteractorStyleImage
{
	public:
		static dvInteractorStyleSelectPoint* New();
		vtkTypeMacro(dvInteractorStyleSelectPoint, vtkInteractorStyleImage);
		
                // OnLeftButtonUp, save the pixel coordinates to the global
variable pointPosition
		virtual void OnLeftButtonUp() {
    		std::cout << "Picking pixel: " <<
this->Interactor->GetEventPosition()[0] << " " <<
this->Interactor->GetEventPosition()[1] << std::endl;
    	
this->Interactor->GetPicker()->Pick(this->Interactor->GetEventPosition()[0], 
                         						this->Interactor->GetEventPosition()[1], 
                         						0,  // always zero.
                         					
this->Interactor->GetRenderWindow()->GetRenderers()->GetFirstRenderer());
			this->Interactor->GetPicker()->GetPickPosition(pointPosition);
      		std::cout << "Picked value: " << pointPosition[0] << " " <<
pointPosition[1] << std::endl;
			vtkInteractorStyleImage::OnLeftButtonUp();
		}
		
                // OnRightButtonUp, close the window
		virtual void OnRightButtonUp() {
			this->GetInteractor()->GetRenderWindow()->Finalize();
			std::cout << "Closing window..." << std::endl;
			vtkInteractorStyleImage::OnRightButtonUp();
		}
 
};

Subject: [vtkusers] vtkPolyData to a vtkUnstructuredGrid
Message-ID: <338CF46B-CDD6-43EE-AE51-62718D0D8FC8@sci.utah.edu>


Hello,

I have a vtkPolyData structure that contains vtkPolyLines or vertex(s). In the course of the coding the vtkPolyData needs to be converted to a vtkUnstructuredGrid. I have used the example here using the append filter:

http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PolyDataToUnstructuredGrid

However, no lines come across only points. I have also iterated through each cell and moved the point id list over with the same results, no lines

As such, I am wondering why lines might not be moved over. 

Cheers,

Allen

It would help if you post an example with some data so that we can see 
exactly what you're doing.

I got a clue from the Glyph3D example, which shows the check for VTK_MAJOR_VERSION <= 5
I then replaced these lines
//    tensorGlyph->SetInputData(polyData);
//    tensorGlyph->SetSourceConnection(cubeSource->GetOutputPort());
    tensorGlyph->SetSource(cubeSource->GetOutput());
    tensorGlyph->SetInput(polyData);
and this one
//    mapper->SetInputData(tensorGlyph->GetOutput());
    mapper->SetInputConnection(tensorGlyph->GetOutputPort());
and now it builds and runs :)

I'll fix the example on the wiki so it works for both vtk5 and vtk6.
 Normally the night builds would catch this, but the example was in
the wring location.

Subject: [vtkusers] Convert set of rectangular images to a set of square
	image set
Message-ID: <CAKKNfu+u8cnRf2_ya7DY3H1RtCa-0TyYbTBap0mEXvpichAGmw@mail.gmail.com>

Hi,

I have a set of rectangular images (example: 256X200) and I need to convert
this set to 256X256 or square images.

Is there a function for this?

Thanks,

Hi,

I need to convert Tilt images to pure Axial, in other words, my imagesn
have tilt different to 0 and I need to convert to Tilt=0.

Is there a method to do this?

Now I have an vtkDataSet object from a reader.I had tried to change the
color of the output of vtkDataSetReader(not set the color of actor), but
had no idea.

The reason is that I want to write the dataset back to hard disk with the
new color.

I could get the number of cells in this dataset, and when I tried to get
the scalars and modify the scalars(it holds the color, am I right), it
crushed.
    this->reader->Update();
    vtkDataSet* ds = reader->GetOutput();
    vtkCellData* cellData = ds->GetCellData();
    vtkDataArray* scalars = cellData->GetScalars();
    int size = scalars->GetSize();//equals to the number of cells in
dataset?
    //then we can  modify scalars...


I am not sure if it is the right way, and I googled it, but found nothing
helpful,

The vtk file was converted from vrml.and it has about 332 points, 110
lines, 102 polygons,and I found in this file there were:
POINT_DATA 332
COLOR_SCALARS VRMLColor 3

So, could any one give me some tips?
Any advice would be appreciated!

POINT_DATA means that you should call ->GetPointData() instead of
->GetCellData().

I am trying to get a better understanding of what I can do with this method of creating a scene using glyphs.  What I want to be able to do is (a) change the position/shape/orientation of a glyph, and (b) add new glyphs.  I am assuming that for performance reasons (I expect to have tens of thousands of glyphs) it will be better to modify an existing actor rather than delete it a create it afresh each time step.  If this is an incorrect assumption please tell me so.

My ideas about this have so far been unsuccessful.  For example, I thought that I could do this in the TensorGlyph example:

after the line

    renderer->AddActor(actor);

add

    tensors->SetNumberOfTuples(3);
    points->InsertNextPoint(0.0, 5.0, 0.0);
    tensors->InsertTuple9(2,1,0,0,0,1,0,0,0,1);
    tensorGlyph->Update();
    mapper->Update();

but this still displays two glyphs.
Is there a way to do what I'm trying to do, or is this misguided?

Thanks
Gib

I'll fix the example on the wiki so it works for both vtk5 and vtk6.
 Normally the night builds would catch this, but the example was in

I find that my modification works if I comment out the first
  tensorGlyph->Update();
(after defining the first two glyphs).  It seems that Update() fixes the mapper's glyph list.

Subject: [vtkusers] Remove Outer Wall from an Open Surface Mesh
Message-ID: <1405298116749-5727840.post@n5.nabble.com>

Greetings,

Im a newbie on VTK.

I'm working on an 3D Interface that lets the user manipulates the mesh after
its loaded. The problem is that many of the models (STL files) that are
going to be opened are cabins with an inner wall (or inner points, if you
prefer) and an outer wall, separeted by ~10cm.

I wish to remove the outer wall points and keep the inner ones. I've
searched through classes like vtkSelectEnclosedPoints or
vtkPolyDataSilhouette but i cannot really find any answer.

Is it possible to it do or do i have to convert it to a 2D model and work it
from there?

Thanks for any help.
Regards

I got the data of points. Then :
vtkDataArray* scalars = reader->getOutput()->getPointData()-> getScalars();
scalars->setTuple3(i, r, g, b);
data->setScalars(scalars);
reader->Update();

but the color didn't changed, is there any step I did wrong?

Then is the setup of the mapper that is wrong.
Moreover, do you know if the data array is an unsigned char one?

The mapper is vtkDataSetMapper, and I use the default setting.
It is sure that the values of params of setTuple3() is 0~255.
Should I not use the setup of the mapper by default?

I removed "reader->Update()" in case of reloading the data on disk, but 
it didn't work.

I think the answer to the question of how to have the actor reflect changes in the polyData is to include these two lines after making changes to points and tensors:

    tensorGlyph->RemoveAllInputs();
    tensorGlyph->SetInput(polyData);

I find that my modification works if I comment out the first
  tensorGlyph->Update();
(after defining the first two glyphs).  It seems that Update() fixes the mapper's glyph list.

Subject: Re: [vtkusers] TensorGlyph

I am trying to get a better understanding of what I can do with this method of creating a scene using glyphs.  What I want to be able to do is (a) change the position/shape/orientation of a glyph, and (b) add new glyphs.  I am assuming that for performance reasons (I expect to have tens of thousands of glyphs) it will be better to modify an existing actor rather than delete it a create it afresh each time step.  If this is an incorrect assumption please tell me so.

My ideas about this have so far been unsuccessful.  For example, I thought that I could do this in the TensorGlyph example:

after the line

    renderer->AddActor(actor);

add

    tensors->SetNumberOfTuples(3);
    points->InsertNextPoint(0.0, 5.0, 0.0);
    tensors->InsertTuple9(2,1,0,0,0,1,0,0,0,1);
    tensorGlyph->Update();
    mapper->Update();

but this still displays two glyphs.
Is there a way to do what I'm trying to do, or is this misguided?

Thanks
Gib

I'll fix the example on the wiki so it works for both vtk5 and vtk6.
 Normally the night builds would catch this, but the example was in

Subject: [vtkusers] How to implement selection with wxPython
Message-ID: <53C36FAF.6040807@gmail.com>

Hi all,

I am a wxpython user and pretty new to VTK.

I need to do (1) embed VTK window into my wxPython frame and
(2)implement selection(bubber band).

I managed to do (1) by using following two classes:

https://github.com/Kitware/VTK/blob/master/Wrapping/Python/vtk/wx/wxVTKRenderWindow.py
https://github.com/Kitware/VTK/blob/master/Wrapping/Python/vtk/wx/wxVTKRenderWindowInteractor.py

For (2), by my study, *classvtkInteractorStyleRubberBandPick* can be
used, but I haven't figured out how to use it with my wxVTKRenderWindow.

Could anyone share some clue?

Thanks in advance.

Kang

Make sure you call that on the mapper. Moreover, you should make sure that
the data array that contains the color if of type vtkUnsignedCharArray

Thanks for the suggestion and apologies for the delay, David.  Are you sure
that a tolerance of 0.5 should be enough?  Wouldn't a lower end contour
intersecting a pixel .75 of the way across still be missed with 0.5, since
{floor(.75 - .5) + 1} is 1?

 

I tried tolerance values of 0.5 and 1.0 but unfortunately got the infamous
streaking artifacts with both, so now I'm keeping the default tolerance and
instead piping the output stencil image data through
vtkImageContinuousDilate3D with a kernel size of (3,3,1).  That seems to
give me the coverage I'm looking for without any artifacts.

 

Thanks again,

Bryan

Have you tried adjusting the Tolerance on vtkPolyDataToImageStencil?

You can try setting it to a large value like 0.5, which gives half a pixel

in tolerance.  That should guarantee that the contour is fully inside of

the result.

Thanks for the quick reply, David.  You're right: I'm in need of inclusivity
on both ends.  I'm voxelizing contours using vtkPolyDataToImageStencil and I
want to ensure that the resulting stencil fully encapsulates the contours.
Are there any tricks to compensate that wouldn't require me to modify my
points directly?  I guess I could just dilate my result, but it would be
nice to have it as tight around the contours as possible.

Hi Bryan,

 

Do you mean inclusive on both ends?  Exclusive on both ends would

just make it worse...

 

The behavior of the rasterization is 100% intentional.  In order for

rasterization to work when there are adjacent areas that are being

rasterized, it must be exclusive on one end and inclusive on the

other end.  Otherwise, adjacent areas could end up with either a

gap between them or with an overlap.

 

The exclusitivity can be compensated for by subtracting a small

tolerance at the lower end or by using other tricks.

 

What is your use case?

 

  - David

Hi everyone,

I noticed that vtkImageStencilRaster has code like the following in
InsertLine and FillStencilData, for both the x and y directions:

if (x1 >= xmin)
     {
     r1 = vtkMath::Floor(x1) + 1;
     }
if (x2 < xmax)
     {
     r2 = vtkMath::Floor(x2);
     }

Correct me if I'm wrong, but it looks like the lower side is exclusive,
while the upper end is inclusive.  The upshot of this is that the only way
to stencil the first pixel is to have a line intersect the row on the
negative side of the first pixel (in the extents).  On the other hand, to
stencil the last pixel a line only need intersect anywhere past the
second-to-last pixel (in the extents).

Assuming that's true, it seems a bit asymmetric.  Is there any way to have
exclusive behavior on both ends?

Thanks,
Bryan

	cout << "Ingresar 1 Para reconstruir imagenes a partir de archivos, o 0
para demo" << endl;
	cin >> key;
	if (key == 1)
	{
		int x, y, z;
		x = y = z = 0;
		recon(x, y, z);
	}
	else
	{
		recondemo();
	}
	  return EXIT_SUCCESS;

}

void recon(int x=0, int y=0, int z=0){}

void recondemo(void){}

//----------------------------------------------------------------------------//

So what i tried to do is going to the project's configuration in VS and
change Type of configuration from .exe to .dll. 

after compiling i tried calling the .dll from a C# application, but when i
run it i get an error saying the format is incorrect.

This is how i call the function in c#:


//------------------------------------------------------------------------------------//
class PlatformInvokeTest
{
    [DllImport("EmbedPointsIntoVolume.dll")]
    public static extern int recodemo();
    [DllImport("EmbedPointsIntoVolume.dll")]
    internal static extern int _flushall();
//------------------------------------------------------------------------------------//
}

So, i'm pretty sure this can be done... but can someone give me an idea on
how? I've read about different ways of calling a .dll ... but i'm pretty
sure i'm not building the .dll right, to begin with.

Hope someone can help me!

Thanks in advance!

Hi Bryan,

Thanks for the follow-up.  Actually, I looked through the code and the
tolerance is only properly applied in the X direction.  But as for
whether 0.5 would be enough (assuming that it was applied uniformly in
all directions), it should be because you just have to be sure that
the _center_ of the voxel is within the contour, so if the contour is
e.g. a square contour with its corners at exact pixel locations, even
a very small tolerance should be enough to make sure that the centers
of all voxels are within the stencil.

About the streaking, in fact I know how to change the algorithm to fix
that, and I've been trying to find time to further develop my
segmentation tools, of which vtkPolyDataToImageStencil is a part.
Unfortunately, I doubt that I'll be able to get started on it until
the fall.

I first tired activiz, but i had no luck making it work in Windows 8 64 bits. 

In what S.O are you using it? If you have any link that might help me, i
would highly appreciate it.

Did you make sure that the ActiViz version is matching your compiler 
(and your compiling option): 64 vs 32bits?

Thanks a lot, i finally got it working. The only way of making it work was
installing the 32 bits version, and setting everything to 32 bits. I guess
it shouldn't be a problem,

Oh yes, I'm using the 32 bits version, you're right, now I see my dll is 32
bits. Sorry I didn't notice before

Hey Allen!

Probably a bug in the append filter, it must not be converting with
polylines type cells correctly for some reason.

As Burlen said it would help if you could post a small example data set.
That will make it trivial to replicate the problem and fix it.

Otherwise, try using a different filter to do the conversion (as a side
effect, like append does). Threshold is my habitual choice for * to
unstructured conversion.

Hi Alexis,

In your example, you should use SetInputConnection() instead of
SetInputData() for your vtkGlyph3D and vtkPolyDataMapper filters.

Hth,
Julien.

The code examples in the book have not been updated to cover the changes to
the library. However, the changes between 5 and 6 are mostly relatively
minor syntactical changes (
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Overview), the overall behavior
and theme of VTK remains the same. So I think you are better off buying now
rather than waiting until the next editions come out. I have no information
yet about when the next books will come out.

Subject: [vtkusers] Use of vtkAlgorithmOutput and vtkSmartPointer
Message-ID: <CAB8-E4CaHmU7=Nr4FZYqJDkMfuXH=SSrL8fYXvZCtz-_jP0UXA@mail.gmail.com>

Dear VTK users,

I am facing a memory issue with the vtkSmartPointer and vtkAlgorithmOutput.

I want to create a function that returns a
vtkSmartPointer for a vtkAlgorithmOutput, on a source object (like a
vtkSTLReader instance).
When I return such a pointer, it seems to me that my source object goes out
of scope, and makes my program crash when I use it (like the input of
SetInputConnection for a vtkTransformPolyDataFilter object).
>From my tries, I guess I have to keep two
vtkSmartPointer alive (one for the source and one for the
vtkAlgorithmOutput)

I was hoping that having a vtkSmartPointer on the
GetOuputPort() of my source object would keep it alive.
Am I missing something?


Below is a source file that shows 3 test cases
1) everything is done in the same function, everything works, and memory is
2) I use a function to generate my vtkSmartPointer<vtkAlgorithmOutput> and
a manual allocation for my source. It works but creates a memory leak
3)
I use a function to generate my vtkSmartPointer<vtkAlgorithmOutput> and a
vtkSmartPointer to handle my source. It does not work at all.

What is the best solution?
Should I create a class to store all these smartpointer


Best regards
Guillaume Jacquenot

Hi Guillaume,

Your observation is accurate. vtkAlgorithmOutput does not store a reference
to its owner and is meant to be used temporarily to connect pipeline
objects. I'd recommend storing the algorithm and the output port index - a
struct of vtkSmartPointer<vtkAlgorithm> and int for example - and calling
GetOutputPort() when needed.

Best,
-berk

Never mind, thanks a lot!

I got a simple sphere example working, but i'm having issues with the code
that was working on c++, i translated it so it compiles, but i get a run
time error saying it's trying to access (0,0,0) which is out of bounds.

Is there something i should know about the transition between c++ and c#?

this is my code.... i'm sure it must be something silly.

    vtkPoints points = vtkPoints.New();
    points.InsertNextPoint(p0[0],p0[1],p0[2]);
    points.InsertNextPoint(p1[0],p1[1],p1[2]);
    points.InsertNextPoint(p2[0],p2[1],p2[2]);
    points.InsertNextPoint(p3[0],p3[1],p3[2]);
    points.InsertNextPoint(p4[0],p4[1],p4[2]);
    points.InsertNextPoint(p5[0],p5[1],p5[2]);
    points.InsertNextPoint(p6[0],p6[1],p6[2]);
    points.InsertNextPoint(p7[0],p7[1],p7[2]);
    vtkPolyData polydata = vtkPolyData.New();
    polydata.SetPoints(points);

	// Construct the surface and create isosurface.	
	vtkSurfaceReconstructionFilter surf = vtkSurfaceReconstructionFilter.New();
    surf.SetInput(polydata);

	vtkContourFilter cf = vtkContourFilter.New();
	cf.SetInputConnection(surf.GetOutputPort());
	cf.SetValue(0, 0.0);

	// Sometimes the contouring algorithm can create a volume whose gradient

Hi Dave,

Thanks for the reply. I dug into the issue a bit more and found the conversion was working fine but a later operation seemed to not return any cell points thus I was thinking the conversion was not working. I just did some more digging and found the issue. In a nut shell an assumption was made that the unstructured grid would contain only polygonal cells (tris, hex, tets, etc) thus a max of eight vertices. A polyline does not fit that assumption. Thus memory got stomped on but did not cause a seg fault.  Thus the classic chasing ones tail was the issue. So no bug but some bad code on our part.

Cheers,

Allen

Subject: [vtkusers] Connecting to arrays in a reader
Message-ID: <CAFuxWZVbyY1ST6n+6Lp+M8V1q5hZfCxMr5E0Nq6p36m9eX0gog@mail.gmail.com>

Hi.

I've been reading the visualization toolkit book and user's guide, googling
a fair bit, and digging through the vtk websites.

I'm not sure how things are meant to connect.  I'm working in python.  I'm
trying to build and use a reader.  Many examples seem to assume there's
only a single field that can be made active.  But in my case, the reader is
where I keep all information, and there is no sense (at least in my mind)
of an "active" field, because several may be used at ones (scalar for
surface coloring, one vector field for one set of cone glyphs, and another
vector field for a different set of cone glyphs, all to be displayed at the
same time).

I create the each field this way (where my_voltages is just a python list
that I parsed from a file):

  voltage = vtkDoubleArray()
  voltage.SetName('voltage')
  voltage.SetNumberOfComponents(1)
  for v in my_voltages:
      voltage.InsertNextValue(v)

And I did the same thing for the 3D fields, except using 3 for the number
of components.
Then, I add these fields to my reader (derived from vtkProgrammableSource)
this way:

  # 1D fields:
  self.GetPolyDataOutput().GetCellData().AddArray(voltage)
  self.GetPolyDataOutput().GetCellData().AddArray(charge)

  # 3D fields:
  self.GetPolyDataOutput().GetCellData().AddArray(current_density_real)
  self.GetPolyDataOutput().GetCellData().AddArray(current_density_imag)

I'm able to iterate through those and print out the correct values and some
of my early scalar visualization with colormaps and such seem to be working.

So, first question is: does what I have done so far seem reasonable or is
there a more vtk-ish way of doing this?

Second question is how to connect to the reader.  I'm trying to use it this
way:

    cone = vtkConeSource()
    cone.SetRadius(0.1)
    cone.SetHeight(0.5)
    cone.SetResolution(8)

    glyph = vtkGlyph3D()
    glyph.SetInputConnection( WHAT GOES HERE??? )

    glyph.SetSourceConnection(self.cone.GetOutputPort())
    glyph.SetScaleModeToDataScalingOff()
    glyph.SetScaleFactor(1.0e-3)
    glyph.SetVectorModeToUseVector()
    glyph.OrientOn()

So the "what goes here" is this question.  Because I used a named array,
I'd hope for something like:

   glyph.SetInputConnection(reader.GetOutputPort('current_density_real'))

But that doesn't work, and I've seen nothing to suggest that it would.
When I try this as the argument,


reader.GetPolyDataOutput().GetCellData().GetArray('current_density_real')

I get:
    TypeError: argument 1: method requires a vtkAlgorithmOutput, a
vtkDoubleArray was provided.

Switching from SetInputConnection() to just SetInput() gives this error
instead
    TypeError: argument 1: method requires a vtkDataObject, a
vtkDoubleArray was provided.

Is this a matter of converting an array to an algorithm output?   It seems
(probably quite wrongly) to me that algorithms can produce many different
kinds of output, and that a vtkArray would reasonably be one of them.  Or,
when using the SetInput(), why wouldn't a vtkArray be a  vtkDataObject?  Of
course, the easy answer is "that's not how the inheritance diagrams are
drawn", but that doesn't really get me closer to groking the intended grand
scheme of things.   I'm not complaining; I'm just confused.

How to I get the glyph to use the vector data (in the vtkArray) as its
input?  (or if that's the wrong way to think about this, then what's the
right way?)

Many thanks in advance for any help/enlightenment.

Greg

hi everyone,

I have looked vtk user guide also webpages up but i cant  find any 
information how we can set the center of the rotation when we rotate 
with mouse because after we pan the object or the model center isnt on 
the initial rotation center it starts to rotate differently.

Thank you for any trick

I think void vtkProp3D::SetOrigin() is what you are looking for.

Hi all,

I'm trying to get a distance widget moving on a certain plane. The widget
measures the distance between two points which I want the user to be able
to modify. As the image is in 3D, when I move a point it doesn't stay in
the current plane and goes somewhere far away to other plane.

How can I force the widget to move on a desired plane?

Thanks.

Some times the Cell locator is giving wrong cell id also.

Do Any one have better solution to find the cell id of a 3D point
correctly.i need to find the normal of that point through that cell id.

Subject: [vtkusers] Automatically configure scalar range for mappers
Message-ID: <CAPFVQX8jqv7mHCUUFwXRiB-au8-kGK4DVw+TbCCOecy+ZNvrUw@mail.gmail.com>

Hello,

I'm new to vtk and I'm having a problem already asked on this forum
but that has never received a response. The previous related posts are
the folowing:
- http://www.vtk.org/pipermail/vtkusers/2012-June/074840.html
- http://public.kitware.com/pipermail/vtkusers/2002-January/009488.html

In my case I have a lsdyna fem analysis loaded correctly through Vtk
that I like to color selecting a particular property (for example
velocity or acceleration) specified in it.

At the moment I'm able to show something similar to what ParaView
display for the model except for the range. If I set statically the
range that I have found with ParaView on a specified model I see the
same colours but I don't know how to calculate the range for a generic
model.

I have tried the following:
- using actor->GetMapper()->GetInput()->GetPointData()->GetArray(id)
to retrieve parameters  related to a property (I think it could be
right because GetName on the array give me the right property name): I
calculated a range but the max is different from that calculated in
ParaView and colours are not so useful. Could it be possible that the
array I'm using is wrong? Or is there some other scaling operation on
those parameters?
- Getting range through GetRange() function but it also don't do me
the same results of ParaView.

Considering that in ParaView there is something similar I think it
could be possible to do so.

Have someone any suggestion to try resolving?

Thanks in advance,
Francesco Argese

Hi Hector - I'm far from an expert, and usually use ParaView for anything
complex.

I wasn't able to figure out anything as good as the slice tool in paraview
for instance, but this might get you going in the right direction. I have
a file with one vector stored in an XML unstructured grid that I did a few
things with:

import vtk

reader = vtk.vtkXMLUnstructuredGridReader()
reader.SetFileName("waveguide_h000022.vtu")
reader.SetPointArrayStatus("H", 1)

#------------------------#
# outline of the dataset #
#------------------------#
get_polydata = vtk.vtkGeometryFilter()
get_polydata.SetInputConnection(reader.GetOutputPort())

outline = vtk.vtkExtractEdges()
outline.SetInputConnection(get_polydata.GetOutputPort())

outline_mapper = vtk.vtkPolyDataMapper()
outline_mapper.SetInputConnection(outline.GetOutputPort())

outline_actor = vtk.vtkActor()
outline_actor.SetMapper(outline_mapper)
outline_actor.GetProperty().SetColor(0.5, 1.0, 0.5)
outline_actor.GetProperty().SetOpacity(0.25)

#---------------------------------------#
# clip with plane normal to z at origin #
#---------------------------------------#
plane = vtk.vtkPlane()
plane.SetOrigin(0.0, 0.0, 0.0)
plane.SetNormal(1.0, 0.0, 1.0)

# re-use the polydata created above
clipper = vtk.vtkClipPolyData()
clipper.SetInputConnection(get_polydata.GetOutputPort())
clipper.SetClipFunction(plane)
clipper.GenerateClipScalarsOn()
clipper.GenerateClippedOutputOn()
clipper.SetValue(0.0)

clip_mapper = vtk.vtkPolyDataMapper()
clip_mapper.SetInputConnection(clipper.GetOutputPort())

clip_actor = vtk.vtkActor()
clip_actor.SetMapper(clip_mapper)

#----------------------#
# vectors in the field #
#----------------------#
arrow = vtk.vtkArrowSource()
glyph_filter = vtk.vtkGlyph3D()
glyph_filter.SetSourceConnection(arrow.GetOutputPort())
glyph_filter.SetInputConnection(reader.GetOutputPort())
glyph_filter.SetScaleModeToScaleByVector()
glyph_filter.SetScaleFactor(0.0007)
glyph_filter.Update()

glyph_mapper = vtk.vtkDataSetMapper()
glyph_mapper.SetInputConnection(glyph_filter.GetOutputPort())

glyph_actor = vtk.vtkActor()
glyph_actor.SetMapper(glyph_mapper)

# --- #
ren = vtk.vtkRenderer()

Hello all,

I have solved using method one. I was doing an error loping on Size
rather than GetNumberOfTuples() of the array in GetPointData and it
was giving me some errors not so clear: in fact it was not a buffer
overflow but only strange values appearing. Probably I must study in
deep vtkDataArray data structure to understand the reason.

Below a sample code extracted hoping that it could be useful for
others. In the code firstFrame is a vector of actors from
lsDynaReader.

Hello,
Francesco

Here is my code:

    for(unsigned int i = 0; i < firstFrame.size(); i++)
    {
        vtkActor *actor = firstFrame.at(i);

        // get polyData from vtkActor
        vtkPolyData *polyData = (vtkPolyData *) actor->GetMapper()->GetInput();

        if(polyData)
        {
            if(polyData->GetPointData())
            {
                   int arrayNum = 3; // Acceleration
                   std::cout <<
polyData->GetPointData()->GetArray(arrayNum)->GetName() << std::endl;
                    vtkDataArray *scalars =
polyData->GetPointData()->GetArray(arrayNum);

                    for(unsigned int i = 0; i <
polyData->GetPointData()->GetArray(arrayNum)->GetNumberOfTuples();
i++)
                    {
                        double magnitude = 0;
                        for(unsigned int j = 0; j <
polyData->GetPointData()->GetArray(arrayNum)->GetNumberOfComponents();
j++)
                        {
                            double value =
polyData->GetPointData()->GetArray(arrayNum)->GetComponent(i, j);
                            magnitude += pow(value, 2);
                        }
                        magnitude = sqrt(magnitude);
                        min = std::min(min, magnitude);
                        max = std::max(max, magnitude);

                        std::cout << magnitude << std::endl;
                    }
            }
        }
    }

    std::cout << "Min found: "  << min << std::endl;
    std::cout << "Max found: "  << max << std::endl;

Subject: [vtkusers]  GeometryIds extraction
Message-ID: <CAAzeLU24F7nM=MgzG-XmQ9CVUvgpOUy7yA72uvpyg9d-SpeVWg@mail.gmail.com>

Hi all,

I generated a .vtu file with Elmer that contains several bodies within it,
each one represented by GeometryIds.

I know how to extract the bodies in Paraview using Selection Query but I'd
like to get it by using VTK.

Does anyone know how can I extract the diferent bodies using GeometryIds in
VTK?

Thank you.

Subject: [vtkusers] special field-data annotation filter or similar
	functionality
Message-ID: <53C7A720.3070701@mh-hannover.de>

Dear mailing list members,


Is there a filter in paraview that allows one to display specific field-data 
(e.g. of points or cells) at the 3D position of the corresponding point/cell in 
such a way that the annotation is hidden if some mesh or voxel object is in 
front? Or if the objects in front have some transparency the annotations are 
only visible as much as the transparency of the objects in front dictates?
I know about the possibility of displaying selection labels via the Find-Dialog.
However these annotations are
- always in front,
- cannot be made partially transparent (as I think was possible in older 
paraview versions than 4.1.0 when vtkVectorText was used) and
- only the active selection can be annotated, ie not multiple datasets.

I found this example in which the text is not always rendered in front of the axes:
https://github.com/Kitware/VTK/blob/master/Examples/Annotation/Python/textOrigin.py
However it uses vtkVectorText (which is not exportable as text into e.g. SVGs 
however vtkTextActor3D is).
I now wonder if only vtkVectorText allows being hidden by other objects or if 
some settings of vtkTextActor3D are not offered for adjustment in the Find-Dialog?
In any case a paraview filter that would offer all 3 features mentioned above 
would be really helpful. Are there any reasons that such a filter cannot be 
implemented in paraview at the present state?
Can such functionality be implemented in general with the current state of VTK?

Any help or hints are very much appreciated
Roman

Subject: [vtkusers] VTK Linking Error
Message-ID: <1405600013375.84028@mail.uc.edu>

Hello,


I am using the vtk library for the first time. I am trying to run a simple example from the vtk examples available online using VS 2010. However I am making some mistake in linking the required vtk lib and directories. I keep getting the following error:


error LNK2019: unresolved external symbol "__declspec(dllimport) public: static double __cdecl vtkLine::DistanceToLine(double * const,double * const,double * const,double &,double * const)" (__imp_?DistanceToLine at vtkLine@@SANQAN00AAN0 at Z) referenced in function _main


I have built vtk using cmake and also added the vtk directory to additional directories and included the vtk library to my project. Could you help me figure out whether I am missing any step in the linking process?



Regards,
Rutuja ?

Subject: [vtkusers] Cannot translate an image using vtkImageReslice
Message-ID: <e16215095865e334bec96fde077cef0c@mufradat.com>

Hello Everyone,

Can somebody please tell me what am I doing wrong in the following code?
using vtkImageReslice I can rotate or scale the image but whatever 
parameters I use to translate the image the output image stays identical 
to the input one. I was expecting the Mandelbrot to be shifted along the 
x,y but that never happens.

You must also call thickReslice->SetOutputOrigin(...);
Set the output origin to be the same as the origin of the
original mandelbrot.

The "Active" concept in VTK is mostly an artifact of days of yore. The
modern way to tell a filter what array to operate on is with
vtkAlgorithm::SetInputArrayToProcess (
http://www.vtk.org/doc/nightly/html/classvtkAlgorithm.html#a42a55ca2c277aecc909ad592d12978aa).
Most but not all filters respect that.

Close but no cigar. Algorithms produce vtkDataObjects, which contain any
number of vtkArrays. Use SetArrayToProcess to tell the filter which of the
arrays you want it to process.

You are not the first.

Are you configuring your example program with cmake?

If you use cmake to configure your project you will be much happier.
There are over 600 vtk examples with corresponding cmake files here:

Enjoy,

Hi, David.

Huge thanks for the explanation.  That makes sense and is now working well
for me.

Subject: [vtkusers] [ActiViz] Attempted to read or write protected memory.
 Hold Reference?
Message-ID: <1405653270199-5727902.post@n5.nabble.com>

Hi! I'm trying to port my working code on c++ to C#, but i cant get it to
work.

It compiles but i get this error :"Attempted to read or write protected
memory. This is often an indication that other memory is corrupt." 

VTK is trying to acces an out of bounds array location.

I've been reading a lot, and the most logical explanation i got was that as
C# is managed, it might be that C# is deleting something that VTK will need
to use later. Some people talk about "Holding Managed references" and also
the importance of sometimes using the Dispose() function.

I tried a lot of things, but i just cant figure it out.

Hope someone can help! and Thanks in advance!

This is my code:

This is not an ActiViz problem. Your sample code doesn't work in C++ 
either. The main reason is that your points are coplanar and the 
vtkSurfaceReconstructionFilter fails to return a surface. If you change 
your first line from:

   double[] p0 = new double[] { 4, 4, 0 };

to

  double[] p0 = new double[] { 4, 4, 1 };

then it should work.

Subject: [vtkusers] Fail to execute DisplayCoordinateAxes example
Message-ID: <!&!AAAAAAAAAAAYAAAAAAAAAPBYvNtrEVBKuoKoo/GW/DLCgAAAEAAAANg0QPN1Pw1JhXJLSjcSKl4BAAAAAA==@rtech.fr>

Hello,

I've got some trouble with this example :
http://www.cmake.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayCoordinateAx
es

All compile fine but when executing one the line :

 

  vtkSmartPointer<vtkAxesActor> axes =

    vtkSmartPointer<vtkAxesActor>::New();

 

 

I get a vtk messagebox that display :

ERROR: In vtkTextActor.cxx, line 112

vtkTextActor (000000000045A570): Failed getting the TextRenderer instance!

 

ERROR: In vtkTextActor.cxx, line 112

vtkTextActor (0000000002429040): Failed getting the TextRenderer instance!

 

ERROR: In vtkTextActor.cxx, line 112

vtkTextActor (00000000024636B0): Failed getting the TextRenderer instance!

 

 

 

My configuration is :

-          Window 7 x64

-          QtCreator 3.2.1 based on Qt 5.3.1 (MSVC 2013 64bit)

-          Vtk 6.1.0 (compiled with MSVC 2012 (CMAKE 2.8.12.2))

 

Thanks by advance.

Are you compiling VTK with the Module_vtkRenderingFreeTypeFontConfig 
turned ON?

This thread might help as well:

   http://www.vtk.org/pipermail/vtkusers/2013-June/080176.html

Also can you make sure that you link with all the available libraries:

    target_link_libraries(DisplayCoordinateAxes ${VTK_LIBRARIES})

Ohh, Thanks a lot! I was over complicating myself...

Now this works.

P.s: Somehow i got this working on c++....

Subject: [vtkusers] Problem with QVtkWidget not rendering vktChartXY in
 visual studio 2013
Message-ID: <DUB125-W947E83538AE21EDA1823BCD6F30@phx.gbl>

Hey there,
I am developing in Linux using gcc 4.8, but this weekend I tried to compile in Windows7 using visual studio 2013 (v120).
The code use QT with the QVtkWidget.

The code works properly in my Linux setup, but it does not render one of the two qtvtkwidget I have. Basically I get a white background where the widget should be, and it corrupts a little bit when resizing.
This widget shows 3 vtkChartXY in the same scene of a qvtkWidget.
I got three warning/errors but no crashing. And I can interact and render the other QtVtkWidget.
First:
"Generic Warning: In D:\Software\VTK\source.git\Rendering\Context2D\vtkContextDevice2D.cxx, line 27
Error: no override found for 'vtkContextDevice2D'."
I have no idea if this one is relevant to be honest. 
Second:
"First-chance exception at 0x01E07B28 in VTKNodesEdgesEXE.exe: 0xC0000005: Access violation reading location 0x00000000."
Debugging this, it points to the render pipeline of the qtvtkWidget, specifically:
vtkContextActor.cxx
// Renders an actor2D's property and then it's mapper.
int vtkContextActor::RenderOverlay(vtkViewport* viewport)
  // Pass the viewport details onto the context device.
  int size[2];
  size[0] = view_viewport_pixels.width();
  size[1] = view_viewport_pixels.height();
  vtkRecti viewportRect(actual_viewport_pixels.x() - view_viewport_pixels.x(),
                        actual_viewport_pixels.y() - view_viewport_pixels.y(),
                        actual_viewport_pixels.width(),
                        actual_viewport_pixels.height());
 //(Breakpoint here:)
this->Context->GetDevice()->SetViewportSize(vtkVector2i(size));

And I also get:
"QWidget::repaint: Recursive repaint detected"

I write down my code where the errors are happening, just in case...  It compiles all right in gcc, so not sure if there is something wrong with it, or I am just messing up the setup in Windows. Any hint or point to a direction to solve this is really appreciated. Or even any suggestion to improve my question being more specific is welcome.

Cheers,
Pablo

Update. It seems that the first error I was getting in Windows is in fact relevant:
"Generic Warning: In D:\Software\VTK\source.git\Rendering\Context2D\vtkContextDevice2D.cxx, line 27
Error: no override found for 'vtkContextDevice2D'."

I went back to my Linux/Ubuntu machine at work, and installed the latest VTK from 'origin/nightly-master'.
And now I am getting the pointed error, and a core dump error in exactly the same code.

I still have the working vtk version though. I installed it a couple of months ago max. It is 6.2, but I don't know how to check minor versions, or the commit from where I installed it.

I use cmake to build, and change the vtk directory (particular_build/lib/cmake/vtk-6.2) seems clean, but I have heard that it is not recommended to have multiple vtk versions installed.

Cheers,
Pablo

Update. It seems that the first error I was getting in Windows is in fact relevant:
"Generic Warning: In D:\Software\VTK\source.git\Rendering\Context2D\vtkContextDevice2D.cxx, line 27
Error: no override found for 'vtkContextDevice2D'."

I went back to my Linux/Ubuntu machine at work, and installed the latest VTK from 'origin/nightly-master'.
And now I am getting the pointed error, and a core dump error in exactly the same code.

I still have the working vtk version though. I installed it a couple of months ago max. It is 6.2, but I don't know how to check minor versions, or the commit from where I installed it.

I use cmake to build, and change the vtk directory (particular_build/lib/cmake/vtk-6.2) seems clean, but I have heard that it is not recommended to have multiple vtk versions installed.

Cheers,
Pablo

Subject: Problem with QVtkWidget not rendering vktChartXY in visual studio 2013
Date: Sun, 20 Jul 2014 18:12:01 +0200




Hey there,
I am developing in Linux using gcc 4.8, but this weekend I tried to compile in Windows7 using visual studio 2013 (v120).
The code use QT with the QVtkWidget.

The code works properly in my Linux setup, but it does not render one of the two qtvtkwidget I have. Basically I get a white background where the widget should be, and it corrupts a little bit when resizing.
This widget shows 3 vtkChartXY in the same scene of a qvtkWidget.
I got three warning/errors but no crashing. And I can interact and render the other QtVtkWidget.
First:
"Generic Warning: In D:\Software\VTK\source.git\Rendering\Context2D\vtkContextDevice2D.cxx, line 27
Error: no override found for 'vtkContextDevice2D'."
I have no idea if this one is relevant to be honest. 
Second:
"First-chance exception at 0x01E07B28 in VTKNodesEdgesEXE.exe: 0xC0000005: Access violation reading location 0x00000000."
Debugging this, it points to the render pipeline of the qtvtkWidget, specifically:
vtkContextActor.cxx
// Renders an actor2D's property and then it's mapper.
int vtkContextActor::RenderOverlay(vtkViewport* viewport)
  // Pass the viewport details onto the context device.
  int size[2];
  size[0] = view_viewport_pixels.width();
  size[1] = view_viewport_pixels.height();
  vtkRecti viewportRect(actual_viewport_pixels.x() - view_viewport_pixels.x(),
                        actual_viewport_pixels.y() - view_viewport_pixels.y(),
                        actual_viewport_pixels.width(),
                        actual_viewport_pixels.height());
 //(Breakpoint here:)
this->Context->GetDevice()->SetViewportSize(vtkVector2i(size));

And I also get:
"QWidget::repaint: Recursive repaint detected"

I write down my code where the errors are happening, just in case...  It compiles all right in gcc, so not sure if there is something wrong with it, or I am just messing up the setup in Windows. Any hint or point to a direction to solve this is really appreciated. Or even any suggestion to improve my question being more specific is welcome.

Cheers,
Pablo

Subject: [vtkusers] vtkCellLocator to detect a collision between a line and

Message-ID: <1405936055567-5727918.post@n5.nabble.com>

Hi guys,

I wonder if my line (it's a vtkActor) touches my other vtkActor.
I can not use vtkCollisionDetectionFilter because I'm on java.

But I can use vtkCellLocator, so I would like to know how to use it to make
a small condition
if (line touches my vtkActor) {
        .........
}

Help me please 

Thank you very much.

Mark.

In linux it is solved if I add to the main CMakeLists.txt:
 include(${VTK_USE_FILE})
It seems like a crucial dependency, but I was able to compile with no errors in old VTK version.

I will test it in Windows soon... and hopefully end this helpful monologue.

Subject: [vtkusers] Python vtk extend mapper
Message-ID: <53CD5DF8.3040202@imeka.ca>

Hi all, Is it possible to extend a mapper in Python VTK? I did a simple 
test, extending vtkPolyDataMapper, overriding RenderPiece with a "1/0" 
statement and a call to the real RenderPiece, and replacing in my code 
the real mapper with this fake mapper. It did nothing. It still draws 
what it was drawing before my test without failing. I did the same in a 
C++ project and it's working perfectly. I also tested extending 
vtkOpenGLPolyDataMapper, just in case. Still nothing.

So, is there any restrictions to overriding vtk classes in Python VTK? 
Thanks for your time.

Hi Nil,

Overriding virtual C++ methods in Python doesn't work.
See the "Subclassing a VTK class" section of the following:

http://vtk.org/gitweb?p=VTK.git;a=blob;f=Wrapping/Python/README_WRAP.txt

Extending filters, mappers, and sources via python requires
the use of special "programmable" base classes like the
vtkProgrammableSource and vtkProgrammableFilter.  There
is no "vtkProgrammableMapper" base class, however.

If you are still here Jas, would you mind telling the mailing list how 
you did <http://xkcd.com/979/>? I'm also searching how to apply a shader 
to a single actor and I had no luck so far. It seems a shader collection 
can only be applied to a render window.

Subject: [vtkusers] Crash/Error by using vtkVRMLImporter with VTK6.1
Message-ID: <1406022793793-5727927.post@n5.nabble.com>

Hi there,

in my application I can import one VRML-object. But my program crashes, when
I load the next VRML-dataobject (with VTK6.1).
With VTK 6.0 it runs fine.

here my (JAVA-)code for loading a new VRML-object:
/
//***** VRML import ******
vtkVRMLImporter importer = new vtkVRMLImporter();
importer.SetFileName(file);
importer.Read();
importer.Update();

vtkActorCollection coll = importer.GetRenderer().GetActors();
coll.InitTraversal();
		
vtkActor actor = coll.GetLastActor();
//*****************************
/

It crashes in the third line ( importer.Read() ).

Is it a bug in 6.1 ?

Subject: [vtkusers] Convert vtkPolyData to vtkImageData - wrong values
 at points where objects intersects
In-Reply-To: <trinity-40347dcf-c165-4028-a3d9-9d2f0d8b11a3-1405502576156@3capp-gmx-bs09>

Hi Chris,


It is likely not vtkAppendPolyData but vtkPolyDataToImageStencil. I'm not sure 
how vtkPolyDataToImageStencil evaluates within intersections.
Instead You could either use a boolean union instead of vtkAppendPolyData, which 
however is likely to be slow.
A possibly faster way could be to OR together output images of each individual 
polydata object.
What in the end actually is faster depends on the complexity of the polydata, 
the number of objects and the needed image resolution.
If both methods are too slow, modifying the code of vtkPolyDataToImageStencil 
might be best.

Hope this helps
Roman

Subject: [vtkusers] CMake problem (VTK 6.1 - Qt 5.3)

Hello, We hope this email find you well.

*We have the follow CMake - VTK - Visual Studio 2013 Configuration:*

?Visual Studio 2013 opengl +64;

?CMake 3.0;

?VTK-6.1.0.

*CMake configurated the following paths:*

?C:\Program Files\VTK (Debug);

?C:\Program Files\VTK (Release);

?C:\VTK\build;

?C:\VTK\Data.

The environment stated above works very well. However, we need to 
provide/enable the same configuration between*VTK* and *QT Enterprise 
Creator 5.3*. We used CMake 3.0 to configure the linkage between *QT 5.3 
and VTK - 6.1.0*.

The following variables were configured in CMake:

?*VTK_Group_Qt:BOOL=ON;*

*?QT_QMAKE_EXECUTABLE:FILEPATH=C:/Qt/Qt5.3.1/5.3/msvc2013_64_opengl/bin/qmake.exe. 
*



Despite of the above configuration, CMake presents this error message:

CMake            Warning at C:/Program Files 
  (x86)/CMake/share/cmake-3.0/Modules/FindQt4.cmake:616           
  (message):  C:/Qt/Qt5.3.1/5.3/msvc2013_64_opengl/bin/qmake.exe

  "C:/Qt/Qt5.3.1/5.3/msvc2013_64_opengl/lib" but          QtCore could 
not be found there. Qt is NOT installed            correctly for the 
target build environment.            Call Stack (most recent call 
first):  GUISupport/Qt/CMakeLists.txt:68 (find_package)

CMake Error at C:/Program Files 
  (x86)/CMake/share/cmake-3.0/Modules/FindQt4.cmake:621           
  (message):            Could NOT find QtCore. Check 
  C:/VTK/bin/msvc2013_64_opengl/CMakeFiles/CMakeError.log for           
  more details.            Call Stack (most recent call first): 
  GUISupport/Qt/CMakeLists.txt:68 (find_package)

Could you guys please advise me on how to properly set up the 
programming environment in which CMake will build the bridge amongst the 
VSC++ OpenGL +64, VTK 6.1.0 and QT 5.3? What are our options to direct 
CMake to recognize QT5.3? The way it is now it only recognizes QT4.0.


Thank you so much.

This page might have what you're looking for [1].  If not please feel free
to update it once this is resolved!

You might want to try setting CMAKE_PREFIX_PATH to the directory containing
the "lib/cmake" directories, which is usually installed with qt
in "C:/path/to/qt-5.3-install/5.3/<your_compiler> " which in your case
is "C:/Qt/Qt5.3.1/5.3/msvc2013_64_opengl".  Note also that it looks like
you have set CMAKE_INSTALL_PREFIX to this value, which tells cmake where
your current project will be installed [2] - probably not what you want.

If all else fails you could try manually pointing QT_QTCORE_LIBRARY_*
variables to those libraries.  This shouldn't be necessary if CMake
correctly finds qt but occasionally helps diagnose the problem nonetheless.

Hey Nil

Search for adding material which will be a xml file containing paths to
shaders and declarations of variables.

This method was removed in 6.2 I think, so search forum for solution of
this. Will send you my email in private message, add me on hangouts if
further help is required.

You don't really give enough information for anyone to help you.  Have you run your code in a debugger?  Stepping into the VTK library code?  Where does it crash exactly?

Cheers,

Hi Luis,

to compile qt 5 or superior with vtk 6, you need to set as well VTK_QT_VERSION = 5,  in cmake.

Cheers,

Waldo.

Subject: [vtkusers] SetInputData migration VTK 6
Message-ID: <CAPGPba+315v=N4h1WfJh4Fyz194BnzKepUsXCHjMXZWB4AhG-Q@mail.gmail.com>

Hello,

I created a pipeline with a vtkSplineFilter, with a polydata as input.
However, now that I try to make it compatible with VTK 6, it's not working
anymore.

I replaced SetInput by SetInputData, and I read that SetInputData doesn't
create the pipeline. That's probably why now, when I update my polydata,
it's not updating the spline.
But I was wondering then how should I do to keep creating the pipeline then
?

I read to use SetInputConnection, but I think SetInputConnection take as
argument the OutputPort of another filter, but the spline is the 'entry
point' of my pipeline, taking a polydata as input, and applying some
filters on it.

How could I do to update the pipeline when modifying the polydata ?

Thank you.
-Laurent

Subject: [vtkusers] vtkAxesActor and rubberbanding in C#...
Message-ID: <A5289A83632D5E4EAE537415D2E23F5F2DE882DF@HOU-EXCM-08.eagle.org>

I'm using Activiz on Windows 7 with an HD4600 graphics processor.  For some reason when I have a vtkAxesActor in my scene, it messes up rubberbanding with the rubberband3d interactor.   The rubberbands will not draw over any background space, although they do draw over 3d objects in the scene.   It doesn't seem to matter whether the axesActor is placed directly in the RenderWindow or in a vtkOrientationMarkerWidget.  Any idea what might cause this behavior?

This is how I'm putting the axesActor in the scene currently.

vtkAxesActor axes = vtkAxesActor.New();
                axes.SetCylinderRadius(.08);
                axes.SetConeRadius(.7);
                axes.SetScale(3);
                axes.SetPosition(-1, -1, 0);
                axes.PickableOff();
                axes.DragableOff();
                axes.SetShaftTypeToCylinder();

                widget = vtkOrientationMarkerWidget.New();
                widget.SetOutlineColor(0.9300, 0.5700, 0.1300);
                widget.SetOrientationMarker(axes);
                vtkRenderWindowInteractor vr = viz.RenderWindow.GetInteractor();
                widget.SetInteractor(vr);
                widget.SetEnabled(1);

Hi Laurent,

After feeding the vtkPolyData into the vtkSplineFilter by SetInputData and

Hi Sam,

Thank you for your answer.

Here is my pipeline (just an overview):

vtkSplineFilter->SetInputData(polydata)

vtkTubeFilter->SetInputConnection(vtkSplineFilter->GetOutputPort())

vtkMRMLModelNode->SetAndObservePolyData(vtkTubeFilter->GetOutput())

I would like to have one vtkMRMLModelNode with one polydata.
The problem if I do what you suggested, is all my vtkMRMLModelNodes are
gonna observe TubeFilter. So when I will modify my polydata and call
vtkSplineFilter->Update() and vtkTubeFilter->Update(), all my
vtkMRMLModelNodes will be updated, but I only want the last one to be.
Should I do a copy of the output of vtkTubeFilter instead ? to avoid they
all change when I update the TubeFilter ?

Thank you.
-Laurent

Hi,

Is there a method in ActiViz that would save a Dicom Image?

I've found this one: vtkImageWriter but the Dicom writer is not there for
some reason.

Thanks,

It is correct that SetInputData() does not connect the pipeline. To be more
specific, consider 2 examples:

1)

polydata = someFilter->GetOutput();

anotherFilter->SetInputData(polydata)
anotherFilter->Update();

someFilter->Modified();
anotherFilter->Update();

Update() would not propagate a pipeline request to someFilter. So the
output of anotherFilter will not change between the 2 Update() calls.

2)

polydata = giveMePolyData();

anotherFilter->SetInputData(polydata)
anotherFilter->Update();

// modify the polydata somehow
polydata->Modified();

anotherFilter->Update();

In this case, because the polydata changed, the second Update() will
actually have an effect and the output of anotherFilter will change after
the 2nd Update.


So the change to your code will depend on the nature of "polydata". Is it
still the output of a filter? Then you must use SetInputConnection().
Unfortunately, this sometimes means that you need to change function
signatures to pass an (algorithm, port index) pair around instead of a data
object.

If polydata is a stand-alone data object that is modified directly by some
code and as a result its mtime is updated, you can use SetInputData(). Keep
in mind that the producer of the data object is now completely out of the
pipeline and will not see any pipeline updates.

I don't know the details of how data is stored in MRML. If you add a
polydata to a MRML node and expect it to represent the output port of a
filter such that you can do this:

vtkMRMLModelNode->SetAndObservePolyData(vtkTubeFilter->GetOutput())

vtkTubeFilter->SetSomething();

polydata = get_MRML_node_somehow();
polydata->Update(); // should cause vtkTubeFilter to re-execute

The MRML code will have to change to store the algorithm and output port
index instead. There is no longer any way to get from a data object to its
producer. In fact, vtkDataObject is now in a module (library) that doesn't
know anything about algorithms or pipelines.

Best,
-berk

Thank you Berk for your answer.

My polydata is not an output of a filter, it's a stand-alone object, that I
modify myself directly.

So what would happen if I had something like this:

polydata = vtk.vtkPolyData()

splineFilter->SetInputData(polydata)
tubeFilter->SetInputConnection(splineFilter->GetOutputPort())

mrmlNode1->SetAndObservePolyData(tubeFilter->GetOutput())

//modify polydata
splineFilter->Update()
tubeFilter->Update() (I don't know if this one is necessary of if Updating
splineFilter will automatically trigger an update of tubeFilter)

mrmlNode2->SetAndObservePolyData(tubeFilter->GetOuput())


My understanding was as splineFilter has been updated after getting the
output of tube filter for mrmlNode1, mrmlNode1 and mrmlNode2 should be
different.
However, it seems that it's not the case. As they both observe the output
of tubeFilter, when I update tubeFilter, it modifies polydata of mrmlNode1
and mrmlNode2.

Is it correct ?

Thank you very much.
-Laurent

Ah, this is a bug but would have been in the old pipeline too. The key is
that tubeFilter->GetOutput() will always return the same object (there are
some exception but they require low level manipulation of tubeFilter). So
during the Update(), the mrmlNode1 polydata will be modified.
Furthermore, mrmlNode2
will always point to the same object. If you want to preserve the output of
a filter even after it executes, you need to copy it to another object.
Something like this:

splineFilter->SetInputData(polydata)
tubeFilter->SetInputConnection(splineFilter->GetOutputPort())

vtkPolyData* pd = vtkPolyData::New();
pd->ShallowCopy(tubeFilter->GetOutput())
mrmlNode1->SetAndObservePolyData(pd)

Subject: [vtkusers] Failed to update polydata - wxVTKRenderWindow.py
Message-ID: <53CF7384.1050708@gmail.com>

Hello,

I wanted to update polydata after Render().

In my test, I made some changes to the original wxVTKRenderWindow.py
(shipped with VTK python release), by adding a Keydown event ('x'),
which calls updatePolydata() to update the polydata
(wxVTKRenderWindow.srcdata). The function looks as follows.

def updatePolydata(self):
self.srcdata = vtk.vtkConeSource()
self.srcdata.SetResolution(32)
self.srcdata.Modified()
self.srcdata.Update()
self.Render()

I expected the new "Cone" will be drawn to the screen, but it didn't
happen.

Did I misunderstand anything about how to update the polydata and piplines?

Here is my testing environment:

OS: Windows 7 (64-bit)
Python: 2.7.7 (32 bit)
wxPython: wxPython2.8-win32-unicode-2.8.12.1-py27.exe
VTK: vtkpython-6.1.0-Windows-32bit.exe

My testing script is attached.

Thanks for your help in advance.

Kang

Dear mailing list members,


Is there already a filter as described below that I've missed to find?
If not, any recommendation how to start implementing such filter?

Kind regards
Roman

The vrml-files? yes.
This files work with vtk 6.0 without crashes.

The vtk-files for using with java was created by cmake and visual studio.

Subject: [vtkusers] vtk6.1/vtkChartXYZ mixing with 3D and OpenGL errors
Message-ID: <1406159123745-5727951.post@n5.nabble.com>

I am trying to mix vtkChartXYZ into a "3D" scene.

I use as an example  this test case that uses vtkChartXY

https://github.com/Kitware/VTK/blob/master/Charts/Core/Testing/Cxx/TestChartsOn3D.cxx
This test case works fine.

When I replace  vtkChartXY in the above test example with a vtkChartXYZ
(filled with meaningful data), I get the OpenGL error

vtkOpenGL2ContextDevice2D (0000000001D8B1C0): failed after PopMatrix 1
OpenGL errors detected
  0 : (1284) Stack underflow

You may ask why I am trying to do this. I am trying to create a spectrogram
plot using a  vtkChartXYZ with a ScalarBarActor in the scene.

Regarding this issue...
By inspection this appears to be an issue in vtkChartXYZ::DrawTickMarks
The PopMatrix() calls below is not matched by a a PushMatrix() under certain
conditions. The code is just not robust.


void vtkChartXYZ::DrawTickMarks(vtkContext2D *painter)
{
  vtkContext3D *context = painter->GetContext3D();
  float bounds[4];

  // draw points instead of lines
  context->ApplyPen(this->Pen.GetPointer());

  // treat each axis separately
  for (int axis = 0; axis < 3; ++axis)
    {
    // pop matrix since we'll be drawing text in 2D before we draw the
    // actual tick marks
    context->PopMatrix();

....
   if (tickSpacing == -1)
      {
      continue;
      }

Further on this issue. The fix is make sure the Pop/Push is balanced
correctly. tickSpacing==-1 is not actually an error condition.

   if (tickSpacing == -1)
      {
      context->PushMatrix();
      continue;
      }

Message-ID: <1406189048777-5727954.post@n5.nabble.com>

Hi,
I have tried to use vtk 5.10 working in OSX maverick, but are having
problems.

I can get the libraries compiling and linking and installing. 

However, when I try to open a vtk window, I get a blank white window and two
messages.

Running an example, the 'Cube' for example give the output

2014-07-24 00:59:53:326 Cube[24232:507] invalid pixel format
2014-07-24 00:59:53:326 Cube[24232:507] invalid context 

I have looked at some threads mentioning maverick problems with 5.10, but
can't find the fix.

Subject: [vtkusers] Issues with using vtkSmartVolumeMapper.
Message-ID: <1406217230762-5727955.post@n5.nabble.com>

Hello Everybody,

I am currently working on some volume rendering and using vtk.6.1.0. I am
aware that since vtk 6.0 the need to init factories for modules. I have done
the same. 
I am having issues when I am trying to create a new instance of
vtkSmartVolumeMapper. It returns the following error:

Generic Warning: In
V:\Research\code\libsrc\VTK-6.1.0\Rendering\Volume\vtkRayCastImageDisplayHelper.cxx,
line 20
Error: no override found for 'vtkRayCastImageDisplayHelper'

On further investigation I gather that this call is returning a NULL.

this->ImageDisplayHelper  = vtkRayCastImageDisplayHelper::New(); (in
vtkFixedPointVolumeRayCastMapper.cxx, Ln 716)

Am I missing something? Is there any other module that needs to be
initialized? (other than the following)

VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingFreeType);
VTK_MODULE_INIT(vtkRenderingFreeTypeOpenGL);

Any help/direction/thoughts would be greatly appreciated. :)

best regards,

Vipul

Maybe you need:
VTK_MODULE_INIT(vtkRenderingVolumeOpenGL);

Hi Bill, 

Thanks for the quick reply. I actually had tried that, with no success.
Infact it throws a linker error.

(error LNK2019: unresolved external symbol "void __cdecl
vtkRenderingVolumeOpenGL_AutoInit_Construct(void)"
(?vtkRenderingVolumeOpenGL_AutoInit_Construct@@YAXXZ) referenced in function
"public: __thiscall
vtkRenderingVolumeOpenGL_ModuleInit::vtkRenderingVolumeOpenGL_ModuleInit(void)"
(??0vtkRenderingVolumeOpenGL_ModuleInit@@QAE at XZ))

Just to be clearer (I should have mentioned earlier, if its not obvious
already), I am working in VS2012.

You will need to include the vtkRenderingVolumeOpenGL library when you
build your app.

If you use cmake to configure your project, you will avoid all of these issues.

Aah, thank you so much Bill. Interestingly for some reason when I built vtk
and then installed it to the destination folder, the library for
vtkVolumeRenderOpenGL was never installed. I was assuming all my .libs were
in order in the Linker additional dependencies. (Assumptions are bad).

Thank you again. 

Regards,

Vipul

It is possible that install rules are broken for volume opengl since most
of the time we do testing using the build tree.

I will have a look at it if no one else volunteers for it.

Hi,
I'm trying to implement an animation program, basing it closely (I think) on this example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Utilities/Animation
Apparently I'm missing something because my program renders my actor correctly in the main program, but the code in the timer callback does not change what is being rendered.  The main program and the callback function are shown below.  The relevant part of the callback code that does not lead to a modified actor being rendered is this:

      strips->Initialize();
      MakeTube(nd, nstrips, dtheta, points, strips);
      polydata->Reset();
      polydata->SetPoints(points);
      polydata->SetStrips(strips);
      mapper->RemoveAllInputs();
      mapper->SetInput(polydata);
      actor->SetMapper(mapper);
      mapper->Update();
      vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::SafeDownCast(caller);
      iren->GetRenderWindow()->Render();

As you can see, I have been flailing around, trying various likely possibilities, revealing my obvious lack of understanding.  Initially I thought it would be sufficient to just change 'points' and 'strips', then I thought I should repopulate polydata, then...

class vtkTimerCallback2 : public vtkCommand
{
  public:
    static vtkTimerCallback2 *New()
    {
      vtkTimerCallback2 *cb = new vtkTimerCallback2;
      cb->TimerCount = 0;
      return cb;
    }

    virtual void Execute(vtkObject *caller, unsigned long eventId, void * vtkNotUsed(callData))
    {
      if (vtkCommand::TimerEvent == eventId)
        {
        ++this->TimerCount;
        }
      std::cout << this->TimerCount << std::endl;
//      actor->SetPosition(this->TimerCount/10., this->TimerCount/10.,0.);

      dtheta = new double[nstrips];
      for (int i=0; i<nstrips; i++) {
          dtheta[i] = 0.0;
      }
      strips->Initialize();
      MakeTube(nd, nstrips, dtheta, points, strips);
      polydata->Reset();
      polydata->SetPoints(points);
      polydata->SetStrips(strips);
      mapper->RemoveAllInputs();
      mapper->SetInput(polydata);
      actor->SetMapper(mapper);
      mapper->Update();

      vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::SafeDownCast(caller);
      iren->GetRenderWindow()->Render();
    }

  private:
    int TimerCount;
    double *dtheta;
  public:
    int nd;
    int nstrips;
    vtkPolyData *polydata;
    vtkCellArray *strips;
    vtkPoints *points;
    vtkDataSetMapper *mapper;
    vtkActor* actor;
};


int main(int argc, char *argv[])
{
    int nd = 20;
    int nstrips = 4;
    double *dtheta;

    PI = 4*atan(1.0);
    vtkSmartPointer<vtkPolyData> polydata = vtkSmartPointer<vtkPolyData>::New();
    vtkSmartPointer<vtkCellArray> strips = vtkSmartPointer<vtkCellArray>::New();
    vtkSmartPointer<vtkPoints> points = vtkSmartPointer<vtkPoints>::New();    // we want just one big array of points
    points->SetNumberOfPoints(nd*(nstrips+1));
    strips->SetNumberOfCells(nstrips);

    dtheta = new double[nstrips];
    dthetafinal = new double[nstrips];
    for (int i=0; i<nstrips; i++) {
        dtheta[i] = 0.1;
        dthetafinal[i] = 0.1;
    }

    MakeTube(nd, nstrips, dtheta, points, strips);
    polydata->SetPoints(points);
    polydata->SetStrips(strips);

  // Create an actor and mapper
  vtkSmartPointer<vtkDataSetMapper> mapper = vtkSmartPointer<vtkDataSetMapper>::New();
#if VTK_MAJOR_VERSION <= 5
  mapper->SetInput(polydata);
#else
  mapper->SetInputData(polydata);
#endif

  vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
  actor->SetMapper(mapper);

  // Create a renderer, render window, and interactor
  vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
  vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
  renderWindow->AddRenderer(renderer);
  vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
  renderWindowInteractor->SetRenderWindow(renderWindow);

  renderer->AddActor(actor);
  renderWindow->Render();

  // Initialize must be called prior to creating timer events.
  renderWindowInteractor->Initialize();

  // Sign up to receive TimerEvent
  vtkSmartPointer<vtkTimerCallback2> cb = vtkSmartPointer<vtkTimerCallback2>::New();
  cb->actor = actor;
  cb->nd = nd;
  cb->nstrips = nstrips;
  cb->points = points;
  cb->strips = strips;
  cb->polydata = polydata;
  cb->mapper = mapper;
  renderWindowInteractor->AddObserver(vtkCommand::TimerEvent, cb);

  int timerId = renderWindowInteractor->CreateRepeatingTimer(1000);
  std::cout << "timerId: " << timerId << std::endl;

  renderWindowInteractor->Start();

  return EXIT_SUCCESS;
}

Subject: [vtkusers] Unable to change the color of a contoursurface made from
 sampling an implicit sphere function
Message-ID: <53D28D0F.4060200@bristol.ac.uk>

Hi,

I have some strange VTK rendering problems.

The attached code should create one blue sphere via:
vtkSphereSource -> vtkPolyDataMapper

And one green sphere via:
vtkSphere -> vtkSampleFunction -> vtkContourFilter -> vtkPolyDataMapper

But for some reason, the second sphere, created via a contour filter,
always renders completely in black on the outside and red on the inside.


How can I get the second sphere to be colored?

I originally noticed that problem while trying out the iceCream.py
example and have the same issue with C++ versions of the code.


Version info:
-Python 2.7.6
-vtk version 6.1.0

OS:
-Ubuntu 14.04.1 LTS

Also attaching glxinfo output.


Regards,
Mike

Ok, I have partially solved my problem.

Running the same script on another computer, I get a completely red sphere
(inside and outside).

And by adding "sphere_mapper.ScalarVisibilityOff()", I now get the expected
green sphere.

I will try on the previous computer again as soon as I can, but I suspect
it won't work or I will only get a green inside (since I had tried changing
the scalar visibility setting before without success).

So it seems to be some sort of graphics driver issue, although I don't
understand why normal polydata objects render without issues, but one
created via contouring/sampling does not.

Any tips on solving the rendering issue would still be appreciated...
Are there maybe any rendering/shading settings I can use to work around it?

Hi Luis,


That is unusual, anyway, do you compiled  qt?, In my case I compiled QT 5.3.1 and after VTK 6.1 and I had not problem, with visual studio 2010.

The first thing that have the first time that compile vtk with qt module is that I have to change the flag to qt 5 and erase the flags of qt 4, and  then I configure again, and is ready.

if you want, send me a screenshot of cmake.

Cheers,

Waldo

I have narrowed down my problem somewhat, and discovered that it is not strictly related to the time callback.  The following code fragment illustrates the point.  I create a shape in polydata and render it, then change the shape and try to render it again.  With this code I see only the first shape.  If I comment out the first renderWindow->Render() then I see the second shape.  Using the timer callback does effectively what this code does, successively modifying and re-rendering the shape, i.e. repeating the three lines of code concerning the second shape.  What do I need to do to ensure that both renders have effect?  (Of course with this piece of code I will not see the first render unless I insert a delay.)

    // This creates the first shape (straight)
    MakeTube(nd, nstrips, dtheta1, points, strips);
    polydata->SetPoints(points);
    polydata->SetStrips(strips);

  // Create an actor and mapper
    vtkSmartPointer<vtkDataSetMapper> mapper = vtkSmartPointer<vtkDataSetMapper>::New();
    mapper->SetInput(polydata);
    vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
    actor->SetMapper(mapper);
    renderer->AddActor(actor);
    renderWindow->Render();        // <<< remove this and the second shape is rendered

    // This creates the second shape (curved)
    strips->Initialize();
    MakeTube(nd, nstrips, dtheta2, points, strips);

Hi,
I'm trying to implement an animation program, basing it closely (I think) on this example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Utilities/Animation
Apparently I'm missing something because my program renders my actor correctly in the main program, but the code in the timer callback does not change what is being rendered.  The main program and the callback function are shown below.  The relevant part of the callback code that does not lead to a modified actor being rendered is this:

      strips->Initialize();
      MakeTube(nd, nstrips, dtheta, points, strips);
      polydata->Reset();
      polydata->SetPoints(points);
      polydata->SetStrips(strips);
      mapper->RemoveAllInputs();
      mapper->SetInput(polydata);
      actor->SetMapper(mapper);
      mapper->Update();
      vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::SafeDownCast(caller);
      iren->GetRenderWindow()->Render();

As you can see, I have been flailing around, trying various likely possibilities, revealing my obvious lack of understanding.  Initially I thought it would be sufficient to just change 'points' and 'strips', then I thought I should repopulate polydata, then...

Subject: [vtkusers] Display only ONE GridPoly per axis in a CubeAxesActor
Message-ID: <53D39328.7020309@posteo.de>

Hi All.

I want to display the axes to a plot in a fashion so that the scales are 
always behind/below the plot (so far so good, works) and shows ONE 
filled plane for X-Y-Z there.
I tried a lot of options, but found no combination that allows that. I 
always get all grid polys shown... I don't need this to work in the same 
CubeAxesActor. If I need to use a second one that would be fine with me.

Any Ideas or do I need to roll my own class?!

Best Regards,

Kim

Subject: [vtkusers] GetNumberOfScalarsInFile method fails with Binary VTK
	data
Message-ID: <53D43BC7.7020102@indiana.edu>

Hello,

This is something I noticed a long time ago, but wasn't sufficiently
motivated to report it, but today I am motivated.  I just tried again
with VTK version 6.1.0 (as it comes with ParaView 4.1.0), and it
still exhibits the same behavior.

Specifically, this is a problem when reading legacy VTK files (using the
TCL or Python interface) that are stored in Binary format.  When stored
in ASCII format, there is no problem.

For instance, the "blow.vtk" file is an example of an ASCII legacy VTK
file with 10 scalars and 10 vectors.  So I can query (with for example
vtkpython):
     >>> dr = vtk.vtkDataSetReader()
     >>> dr.SetFileName("blow.vtk")
     >>> dr.Update()
     >>> dr.GetFileType()
     1
     >>> dr.GetNumberOfScalarsInFile()
     10
     >>> dr.GetNumberOfVectorsInFile()
     10
     >>> dr.GetNumberOfFieldDataInFile()
     0

But if I try the same for a Binary formatted legacy VTK file, then
it will report either 0 or 1 scalar or 0 or 1 vector.


As a secondary question -- I was trying to convert the ASCII blow.vtk
file to a Binary VTK file to provide as an example for demonstrating
the issue abvoe, but I'm having trouble doing an ASCII to Binary
conversion using the VTK scripting interface in a way that keeps the
scalars in the scalar list.  I can get them all read, but then writing
them causes most of them to be shifted down as "FieldData" rather than
Scalars.  So my other question is:
           A) How to read a file and write it back out in the same 
structure?
              (perhaps switching only the ASCII flag to Binary)

and/or    B) How to write multiple scalar entries using VTK scripting.

Of course, I can create these files with an AWK script, but I'd like
to be able to do it completely within the VTK scripting environment.


(Binary file with multiple scalars available upon request.)

     Thanks,
     Bill

In case anyone is interested, I found the simple solution.

      renderer->RemoveActor(actor);
      renderer->AddActor(actor);

Subject: [vtkusers] Oculus Rift: vtkLensWarp - failure for request:
	vtkInformation
Message-ID: <1406499465421-5727984.post@n5.nabble.com>

Hey there guys. I'm currently working on an augmented reality stereo display
for the Oculus Rift, which requires a barrel distortion on each eye. For
this, I have four renderers (two for each eye) in a single render window.
I'm trying to get the output of the vtkImageImport objects that process cam
data for the background of each eye distorted using a vtkWarpLens. However,
I am constantly running into a blank display and an error that states:

vtkStreamingDemandDrivenPipeline (0x3002f80): Algorithm
vtkWarpLens(0x3002320) returned failure for request: vtkInformation
(0x3004560)
  Debug: Off
  Modified Time: 1836
  Reference Count: 1
  Registered Events: (none)
  Request: REQUEST_DATA_OBJECT
  FROM_OUTPUT_PORT: 0
  ALGORITHM_AFTER_FORWARD: 1
  FORWARD_DIRECTION: 0

I don't really know what to make of this. I assume it's because I'm passing
vtkWarpLens a vtkImageData object instead of a vtkAlgorithmOutput or
whatever it is, but because I'm working in Python, it's a little unclear as
to what's going on. The only example of vtkWarpLens usage I could find was a
test file, as there are no examples. Can anyone help me out?

Subject: [vtkusers] Why Axis Labels (X,Y,Z) do not show (Axes.py)?
Message-ID: <53D59F03.3090809@gmail.com>

Hello,

When I ran the attached Python script, the axis lables (X,Y,Z) didn't
show up. I also tried playing with
axes.GetXAxisCaptionActor2D().GetCaptionTextProperty.SetColor(1,0,0) and
SetXAxisLabelText(), but no success.

PS, the script could be found at:
http://www.cmake.org/Wiki/VTK/Examples/Python/GeometricObjects/Display/Axes.

Could anyone help to share some clue?

Subject: [vtkusers] Boundary set information in VTU file
Message-ID: <C870740C-1F28-4CC3-A4EF-169B1099D049@psu.edu>

Hi,

I would like to associate an integer value with mesh boundaries in a *.vtu file.  I cannot find any syntax for doing this, but I assume it is possible.  I have in mind visualizing something like side sets/node sets in exodusII files.

Can anyone provide me with a small text.vtu file to show me how to do this?

Thanks.

I see the labels when running your script.
Both with VTK 5.8.0 and VTK 6.1.0.

Changing the text and its color also works.

Maybe it is a rendering issue similar to the one I have with colors on
surfaces creates from sampled implicit functions.

I'm using python 2.7.6, but I don't think that's where the problem comes
from.

OS: Ubuntu 14.04.1 LTS (64bit)
Python: 2.7.6 (64bit as well I guess, distro package)
VTK: 5.8.0 from the ubuntu repositories and 6.1.0 compiled from source

 I'm a VTK-noobs, so I hope someone has an idea. This is my code to
create the axes:

 double axesColor[3] = {0, 0, 0};

m_axesActor->SetVisibility(1);

m_axesActor->SetCamera(m_renderer->GetActiveCamera());

m_axesActor->SetBounds(m_surfaceMapper->GetBounds());

m_axesActor->SetTickLocationToOutside();

m_axesActor->SetFlyMode(VTK_FLY_OUTER_EDGES);

m_axesActor->SetGridLineLocation(VTK_GRID_LINES_FURTHEST);
 //setup x
axis
 m_axesActor->DrawXGridlinesOn();

m_axesActor->GetXAxesLinesProperty()->SetColor(axesColor);

m_axesActor->GetXAxesGridlinesProperty()->SetColor(axesColor);

m_axesActor->GetXAxesGridpolysProperty()->SetColor(axesColor);

m_axesActor->GetXAxesInnerGridlinesProperty()->SetColor(axesColor);

m_axesActor->XAxisMinorTickVisibilityOff();

m_axesActor->SetXAxisLabelVisibility(1);

m_axesActor->GetTitleTextProperty(0)->SetColor(axesColor);

m_axesActor->GetLabelTextProperty(0)->SetColor(axesColor);
 //setup y
axis
 m_axesActor->DrawYGridlinesOn();

m_axesActor->GetYAxesLinesProperty()->SetColor(axesColor);

m_axesActor->GetYAxesGridlinesProperty()->SetColor(axesColor);

m_axesActor->GetYAxesGridpolysProperty()->SetColor(axesColor);

m_axesActor->GetYAxesInnerGridlinesProperty()->SetColor(axesColor);

m_axesActor->YAxisMinorTickVisibilityOff();

m_axesActor->SetYAxisLabelVisibility(1);

m_axesActor->GetTitleTextProperty(1)->SetColor(axesColor);

m_axesActor->GetLabelTextProperty(1)->SetColor(axesColor);
 //setup z
axis
 m_axesActor->DrawZGridlinesOn();

m_axesActor->GetZAxesLinesProperty()->SetColor(axesColor);

m_axesActor->GetZAxesGridlinesProperty()->SetColor(axesColor);

m_axesActor->GetZAxesGridpolysProperty()->SetColor(axesColor);

m_axesActor->GetZAxesInnerGridlinesProperty()->SetColor(axesColor);

m_axesActor->ZAxisMinorTickVisibilityOff();

m_axesActor->ZAxisLabelVisibilityOn();

m_axesActor->GetTitleTextProperty(2)->SetColor(axesColor);

m_axesActor->GetLabelTextProperty(2)->SetColor(axesColor);

m_axesActor->GetLabelTextProperty(2)->SetOrientation(-90.0);
 //setup
unit strings
 m_axesActor->SetXUnits("");
 m_axesActor->SetYUnits("");

m_axesActor->SetZUnits("");
 //add to scene

m_renderer->AddActor(m_axesActor);

Now, if I enable grid polys:
"m_axesActor->DrawXGridlPolysOn()" I get a grid of polys (which the name
states, obviously), 
but I want just ONE poly in the same plane where
axes are... (Sort of like this:
http://cloud.originlab.com/www/resources/graph_gallery/images_galleries/graph_gallery_3dxyywalls_500px.gif

If there's a different way/class I need to use to achieve this,
please feel free to tell me.

Best Regards,

Kim

Subject: [vtkusers] Extensions to the MetaImage (MHDs) IO-plugin to support
 compression and MHAs
Message-ID: <53D65CD8.4080305@mh-hannover.de>

Dear mailing list members,


I've extended the MetaImage (used by e.g. ITK/VTK)  IO-plugin from Kang Li 
(http://www.kangli.org/code/MetaImage_Reader_Writer.html) to also support 
compression and local data storage, i.e. MHAs. The MetaImage Reader/Writer from 
(http://ij-plugins.sourceforge.net/plugins/3d-io/) seems not to support this 
either.
Reading and writing in Fiji was tested with MHDs and MHAs created/read by 
ITK-4.5.1. While the plugin handles files bigger than 4GB correctly, (for 
unknown reasons my) ITK seems to have problems with MHDs/MHAs bigger than 4GB 
(in general).
The plugin does not check whether the size of the compressed data is correct, 
ITK however does. If the header lacks an entry of CompressedDataSize, ITK throws 
an error when reading/loading such a file. If the size specified with 
CompressedDataSize is too big, ITK just issues a warning. This was used as a 
workaround because I did not find an easy way in Java to put the correct value 
for CompressedDataSize without using extra temporary files (which might be quite 
big).

Attached are the modified files (java-files, plugins.config and a repacked 
IO_-2.0.0-SNAPSHOT.jar).
A modified HandleExtraFileTypes.java (based on: 
https://github.com/fiji/IO/blob/master/src/main/java/HandleExtraFileTypes.java) 
is also included.
Togehter with the modified Plugin it allows opening MHDs and MHAs directly.


The repacked IO_-2.0.0-SNAPSHOT.jar was generated with:

javac -cp /opt/fiji/Fiji.app/jars/ij-1.48a.jar:. MetaImage_Reader.java
javac -cp /opt/fiji/Fiji.app/jars/ij-1.48a.jar:. MetaImage_Writer.java
javac -cp /opt/fiji/Fiji.app/jars/ij-1.48a.jar:. MetaImage_CWriter.java

javac -cp /opt/fiji/Fiji.app/jars/ij-1.48a.jar:. HandleExtraFileTypes.java

The compiled Class-files were moved to a subfolder named io/:
ExtendedFileOpener.class  MetaImage_CWriter.class  MetaImage_Writer.class
ExtendedFileSaver.class   MetaImage_Reader.class   ReplacingInputStream.class

And then included/replaced with zip:
zip -r IO_-2.0.0-SNAPSHOT.jar plugins.config HandleExtraFileTypes.class io/

Feel free to add these extensions to the Plugin-Page or the ImageJ/Fiji repository.
Any suggestions concerning improvements are very welcome.


Many thanks for ImageJ/Fiji and the initial Metaimage IO-plugin.
Roman

Subject: [vtkusers] Problem with volume rendering inside of Qt application
Message-ID: <CAAH=2zZR15DPxtdW9Z0P-YYRfwuySv+MEsJvcLreKBDrfVF+5Q@mail.gmail.com>

Hello,

I have a strange problem with showing VTK volume in QVTKWidget. I can
compile example such as as:
http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/Medical/Cxx/Medical4.cxx
and it work fine. But when I want to use exactly the same code in my sample
Qt application (let's say - render only after user press a button) nothing
is shown in QVTKWidget (I tried also with QVTKInteractor instead of the one
from example). I have this problem only when I want to use vtkVolume and
than add the volume to renderer with AddVolume. If I make other 3D
visualisation for example with vtkContourFilter and than I add it to
renderer with AddActor method - everything works fine.
I was trying to solve this problem for a couple of days but I found some
things that I can't understand in any way. If I take, for example,
Medical4.cxx file and add there
#include <QApplication>
and than
QApplication a(argc, argv); as a first instruction in main - nothing is
rendered. But if I move this line after iren->Start() - it renders well
again. So my question is - is it some kind of known issue that I have to
make some part of VTK pipeline initialization before Qt application could
start? Or maybe I am doing somthing totaly wrong? Thanks in advance if
someone could help me, I would also apreciate if someone could check the
behaviour with this
QApplication a(argc, argv);
instruction inside (for example) Medical4.cxx - if nobody will be able to
reproduce it, maybe I will try to build on other OS. Currently I am working
on Ubuntu 12.04 with VTK 5.8 and Qt 4.8.1.

Best regards,
Jakub

Subject: [vtkusers] invalid drawable ; Mac OSX Mavericks and vtk 6.1
Message-ID: <1406585035759-5727997.post@n5.nabble.com>

Hello,
I have some vtk code that works fine under windows and linux. I have tried
to port this code to the Mac. Originally I used vtk 5.10 and the first
problem I detected was a 'invalid drawable' error occurring. 

Googling around, many people have observed the 'invalid drawable' problem. I
thought it would be a problem fixed in vtk 6.1, so I updated my code to use
6.1. However, I now see the problem is still present in 6.1.

I have code that allow the user to do some window interaction, and press
'e', for exit, and then, 'restart' the interaction mode. This seem to
trigger the 'invalid drawable' error. 

For me this is a show stopper and I have not yet seen any solution to this
problem. 

There are suggestions on the vtk wiki to 'restructure the code' to 'make the
window visible' prior to rendering.
http://www.vtk.org/Wiki/VTK/OpenGL_Errors) . But there is no explanation on
that page what that means? Anyone knowing?

The other two bullets on that page are to no help either I am afraid. I
can't ignore the error by the cmake variable. There seem not to be any need
to detect the 'invalid drawable' condition, since I don't know what to do at
that point to make it valid. 

What seem to be needed is to create a state of 'valid drawable'. Question is
how to do that. 

Any help appreciated. I suppose this must bite many mac people.

Hi.  I have Finite Element data that contains 0D, 1D, and 2D elements.  For displaying the mesh I need the options of displaying all these cell types together or any of the above on their own.  I'm having a bit of a difficult time figuring out the most efficient way to set this up.   Is there a way to set this up with everything contained in a single polyData or would it be better to use a separate polydata for each type?  I currently have everything in one vtkPolyData but I don't see an obvious set of extractors or mappers to just retrieve certain cell types.  Thanks for any suggestions!

Hi Totte,

This error occurs when you call Render() on a vtkRenderWindow when
the window has not yet been mapped to the screen. The most common
case is when VTK is used with Qt and the render window is inside a Qt
widget that is not yet visible.  The way that I avoid 'invalid drawable' is
by doing a "widget->isVisible()" check on my Qt widget before every
call to "renderwindow->Render()":

  if (widget->isVisible()) {
    renderwindow->Render();
  }

At the very least, you need some kind of check to make sure that
Render() is never called before the widget becomes visible.

Hi Mike,

Thanks a lot for your reply.

I did some further investigation and here are the findings:

- Upgrading PyOpenGL to 3.1.0 didn't help;
- The attached simple vtkTextActor example didn't work either ("Hello 
World!" didn't show up).

I also tested on another machine (WinXP 32-bit, Python 2.7.5, VTK-Python 
6.1.0), and it worked fine.

It seems something broken with my win7 machine. Will come back to share 
if I get any new findings...

Thanks again.

Kang

Dear Maillist Members:

           I'm trying to visualize a marine data of NetCDF format.
 I've read in the data with vtkNetCDFReader, and find that there
 are five parameters, which are longitude, latitude, altitude(the
 value is constant), time (the value is constant), and the temperature
of sea surface.
        I want to know how to read out the specific value of each parameter
 respectively, then to visualize it.
        Thank you.

 Hi.

I do this (using Windows and Qt) by deriving from QVTKWidget2,

overwriting the ShowEvent() in that class and sending a signal from
that event function.
Then, In the slot that is called, do your setup,
e.g. AddRenderer and initializing the interactors...

Hope that
helps,

Kim

Hello Kiro and David,
Thanks very much for response. I can see you have a solution for this
problem when you are using qtwidgets. I do believe I'm not using those
widgets, but I'm not sure cause I'm new to the mac. Does perhaps the
simplest vtk example create a widget?

Anyway, I did created a very simple example demonstrating my problem, which
happens when trying to 'reuse' a vtkInteracactor, i.e.

  main()
  {
  // setup vtkwindow, renderer and interactor

   // Render and interact
   renderWindow->Render();
   renderWindow->SetWindowName("First Window");
   
  //Interact until user presses 'e'
  renderWindowInteractor->Start();

  std::cout << "Window 1 closed..." << std::endl;
  //Now do some changes to the 'scene'.. and then start interaction again..

  //Hoops this does not work.. :(
  renderWindowInteractor->Start(); //<-- Actually, here I don't even see a
window
 }

Question is, how to rewrite the above code (for the mac) so I can provide
the user with 'two passes' of interaction?

Currently, code like this is called in python scripts. The user sets up a
'scene' and interacts with it. When 'e' is pressed, the code moves on and
some things are changed in the scene, and then a subsequent interaction
session is to be opened.

As you can see, this code is not designed with a UI, but is just meant to
work with the simple 'interaction' tools that the vtk interactor provides

Perhaps I need to create a completely new renderwindow and interactor? 
tk

Hi. I am beginner with Qt and VTK. Then,  I will let you how I have 
doing. I have been working with Qt 5.3.1 and VS2013 perfectly. Last week 
I tried to set up VTK 6.1 with VS2013 through CMake 3.0 and works 
perfectly. As well you could see below.  Now, I am try to enable VTK 
with Qt 5.3.1 through CMake. However, whatever I do to set VT_QT options 
my CMake only found Qt4 through this file FindQt4.cmake in my C:\Program 
Files (x86)\CMake\share\cmake-3.0\Modules. I am pretty sure that it's 
the problem.



*CMAKE_INSTALL_PREFIX : C:/Program Files/VTK/buildQt**
**CMAKE_PREFIX_PATH: C:/Qt/Qt5.3.1/5.3/msvc2013_64_opengl/bin*
*VTK_Group_Qt:BOOL=ON;**
QT_QMAKE_EXECUTABLE:FILEPATH=C:/Qt/Qt5.3.1/5.3/msvc2013_64_opengl/bin/qmake.exe. 

*





Where I could change that?
"The first thing that have the first time that compile vtk with qt 
module is that I have to change the flag to qt 5 and erase the flags of 
qt 4, and  then I configure again, and is ready."

Thank you.

Hi Totte,

I'm not sure, but it might work if you call Initialize() before Start():

  renderWindowInteractor->Initialize();
  renderWindowInteractor->Start();

Hi David, 
I tried the Initialize() call, but that did not make a difference.

Hi Luis.

Try toggling "Advanced" in the CMake GUI. There is a Qt4/Qt5 switch 
hidden there somewhere...
I have successfuly compiled VTK 6.1.0 with Qt 5.2.1, so 5.3 should work, 
but I have never tried it with CMake 3...

Best Regards,

Kim

Luis, you should have no problems building VTK 6.1+ with QT5.3  and VS2013
I have attached the instructions I use.
There is a link you also might like to look at:
http://www.vtk.org/Wiki/VTK/Configure_and_Build#Qt5..2A

However my instructions do differ from those there.

Regards
   Andrew

Allow VTK to build against Qt5
Since VTK build system has been updated to make use of CMake macros
specific to Qt5, the support has to explicitly enable configuring VTK
with -DVTK_QT_VERSION:STRING="5"

Additionally, in case Qt5 is not installed in a standard location,
a custom prefix for "find_package" should be passed.

You should set these environment variables:

On Mac OS X Mavericks:
  export QTDIR=~/Qt/5.3/clang_64
  PATH=$QTDIR/bin/:$PATH
  export PATH

On Linux (if you have installed Qt):
  export QTDIR=~/Qt/5.3/gcc_64
  PATH=$QTDIR/bin/:$PATH
  export PATH

On Windows:
  QTDIR=C:\Qt\Qt5.3\msvc2012_64_opengl
  CMAKE_PREFIX_PATH:STRING=C:/Program Files (x86)/Windows Kits/8.0/Lib/win8/um/x64
  PATH=%QTDIR%\bin:%PATH%
  For VS2013 set:
  QTDIR=C:\Qt\Qt5.3\msvc2013_64_opengl
  CMAKE_PREFIX_PATH:STRING=C:/Program Files (x86)/Windows Kits/8.1/Lib/winv6.3/um/x64
  PATH=%QTDIR%\bin:%PATH%

In the case of Windows and Mac OSX Mavericks:
If QTDIR is set and %QTDIR%\bin is added to the system path you do not need
 to set CMAKE_PREFIX_PATH for the QT directory. However in the case of Windows
 you can set CMAKE_PREFIX_PATH to where the OpenGL libraries are stored, thus
 removing the need to manually set it each time a new CMake file is generated.

On Windows:
  If you are using OpenGL:
  For VS2012:
  -DCMAKE_PREFIX_PATH:STRING=C:/Program Files (x86)/Windows Kits/8.0/Lib/win8/um/x64
  For VS2013:
  -DCMAKE_PREFIX_PATH:STRING=C:/Program Files (x86)/Windows Kits/8.1/Lib/winv6.3/um/x64


See: https://github.com/Kitware/VTK/commit/384636ec9f442db83c8b827d7eabc7ada9ef8d35
and: http://scriptogr.am/davidok8/post/building-and-using-qt-5-with-cmake


When using Windows, you may need to Eliminate a warning when building in Windows
 that relates to static linking of Qt executables to qtmain.lib.
 This policy was introduced in CMake version 2.8.11. CMake version 2.8.11.2
 warns when the policy is not set and uses OLD behavior.

Just do this:

if(POLICY CMP0020)
  cmake_policy(SET CMP0020 NEW)
endif()

It is better not to change the CMake file because if you update VTK this
file will be overwritten.

When you first start cmake you can always use Add Entry, type in the name:
VTK_QT_VERSION set the Type to String and type in 5 for the value.

Same problem here.

I'm using Qt 5.3.0 with VTK 6.1.0.?
I have a problem with the depth (zbuffer) on my QVTKWidget. The problem appears only on Linux with specific graphical cards (ati or intel chipsets).

Is there a solution to this problem ?

Best.

Hi all,
I've managed to compile VTK and my project against Qt5, unfortunately on my Linux environment I get a weird rendering problem when using QVTKWidget. 
It seems that it cannot understand properly the order of the actors (zbuffer?) displaying sometimes also the actors backfaces.
If I use a regular vtk rendering pipeline, I'm not getting any trouble.
I compiled it also on a Mac and it is working correctly.
Do you have any hint on how to solve the issue?
Thanks a lot
Luca

Message-ID: <86720CEB7DB11A42AB0DEDBA5AD2A48709ED9FDC@MSRV-EXCH01.ccfepc.ccfe.ac.uk>

Does anybody know if there is a way to use quadratic pentahedral (wedges and pyramids) elements in a VTK file with an unstructured grid. I have had a look in the VTK File Formats document<http://www.vtk.org/VTK/img/file-formats.pdf> and it only lists cell types for quadratic hexahedral and tetrahedral 3D elements.

Thanks,

Hi Tim,

There are vtkQuadraticPyramid and vtkQuadraticWedge classes in VTK/Common/DataModel. As far as how the nodes are ordered, you are probably best off creating some simple elements with a python script, saving the result and examining the resulting file. You might also see if there are any tests that use those classes listed in the doxygen documentation.

Message-ID: <CALBJ7LKjeYpFxMqhhgZWXw_s=GoOJud=stHApCo1Uvs8U053SQ@mail.gmail.com>

Dear Paraview users, and VTK users

I want to build a vtkUnstructuredGrid from several numpy arrays, which
contains the points coordinates, the cells, cells locations, cells types
etc...
So : I have all informations that are needed.

vtkPolyData seems a lot easier to define through a python script.

But : what is the fundamental difference between vtkPolyData and
vtkUnstructuredGrid ?
What should be the criterion in order to choose on of these two types ?

Many thanks in advance,
Regards,

Aur?lien

Hi Aur?lien,

The conceptual difference between the two is that unstructured grids can have volumetric cells while polydata cannot.

Message-ID: <CALBJ7LKJfh27DWUPfwy5SA+xMQjzK4jZSchffnWZ4NP9nWtX0A@mail.gmail.com>

Hi all,

I am still facing some issues in order to build a vtkUnstructuredGrid from
numpy arrays.

I have read the example, that shows how to build a vtkUnstructuredGrid cell
by cell :
http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/DataManipulation/Python/pointToCellData.py

But in my case, I have large numpy arrays which contains
- the points coordinates
- the cell types
- the definition of cells (npts,p0,p1,...p(npts-1)

and I would like to avoid any loops in the python code.

Then, I tried the following code, where

   - <cells> contains the definition of the cells (npts,p0,p1,...p(npts-1)
   - <cellslocations> contains the index of the cells in the <cells> array
   - <cellstype> is an array of integer that describes the types of the
   cells

    bloc = vtk.vtkUnstructuredGrid()
>

    bloc.SetCells(

This code works. But when I am trying to cut the resulting block using a
VTKCutter, I have the following error message:

> Generic Warning: In

It is obvious that I do something wrong.... But I can not find where.
Do you have some advice ?
is it really possible to define an unstructured grid like this, avoiding
any python loop ?

Many thanks in advance,

Regards,

Aur?lien

Ok, found it. It was not a big issue... ! Just had to take a look on the
help.

I had to switch to lines in the SetCells method, according to the
description in the help.

bloc.SetCells(
>         numpy_support.numpy_to_vtk(cellslocations, deep = 1, array_type =
> vtk.vtkUnsignedCharArray().GetDataType()),
>         numpy_support.numpy_to_vtk(cellstypes, deep = 1, array_type =
> vtk.vtkIdTypeArray().GetDataType()),
>         vtkCells
>         )


becomes :

bloc.SetCells(
>         numpy_support.numpy_to_vtk(cellstypes, deep = 1, array_type =
> vtk.vtkUnsignedCharArray().GetDataType()),
>         numpy_support.numpy_to_vtk(cellslocations, deep = 1, array_type =
> vtk.vtkIdTypeArray().GetDataType()),
>         vtkCells
>         )
>

(note the switch between cellstypes and cellslocations in the method)

All is working well now.
Sorry for the email. (but an example of defining an UnstructuredGrid from
numpy arrays is now online)

Subject: [vtkusers] Urgent: vtkImageActor not rendering
Message-ID: <1406761326125-5728031.post@n5.nabble.com>

I'm currently stuck upon an issue with a deadline in a week and I could
really use some assistance. I implemented, initially in Python now ported to
C++, a program to display two side-by-side renders of a model overlayed on
two webcam feeds. In Python, this was working wonderfully. The video filled
the entire viewport on each side and the models rendered perfectly. However,
now that I'm in C++, the videos do not render and I cannot figure out why.

To first detail my class structure, I have written a vtk3DRender class that
utilizes a vtkCallbackCommand to call a non-member function TimerCallback.
The trigger for this callback is a timer attached to the
vtkRenderWindowInteractor I'm using. All render elements are private members
of the vtk3DRender object. All configuration of render elements is done in
the constructor.

I'm acquiring the video using OpenCV to obtain a cv::Mat in TimerCallback
which I then use as the c array to pass to a vtkImageImport. This
vtkImageImport then passes its output to my vtkImageActor through a
vtkImageFlip. In Python this worked great. However, now I'm just getting
black in the background where there should be my webcam feed.

Here's the relevant code:

TimerCallback function:

void TimerCallback(vtkObject* caller, long unsigned int eventId, void*
clientData, void* callData)
{
        // Set up reference to vtk3DRender object
        vtk3DRender* v3DR       =
reinterpret_cast<vtk3DRender*>(clientData);

        // Configure frame acquisition
        Mat frameL;
        v3DR->webcamL.read(frameL);
        if (frameL.empty())
                return;
        //cvtColor(frameL, frameL, CV_BGR2RGB);

        // Pass frame data to pipeline and set modification flag
        v3DR->imgPort->SetImportVoidPointer(frameL.data);
        v3DR->imgPort->Modified();
        v3DR->imgPort->Update();

        // Set and print output positions of cams
        v3DR->camR->SetPosition(xyz[cur], xyz[cur+1], xyz[cur+2]);
        v3DR->camL->SetPosition(xyz[cur]+40, xyz[cur+1], xyz[cur+2]);
        cur+=3;

        // Rerender
        v3DR->iren->Render();
}


Related code within initializer (Anything with suffix ___BGL is related to
left webcam renderer and ___BGR is to right):
{
        ...
        //Initialize left webcam (Right not yet implemented)
        webcamL = VideoCapture(0);
        Mat tmp;
        webcamL.read(tmp);

        // Initialize image importer for conversion from OpenCV format to
VTK
        imgPort         = vtkSmartPointer<vtkImageImport>::New();
        imgPort->SetDataSpacing(1,1,1);
        imgPort->SetDataOrigin(0,0,0);
        imgPort->SetWholeExtent(0, tmp.size().width-1, 0,
tmp.size().height-1, 0, 0);
        imgPort->SetDataExtentToWholeExtent();
        imgPort->SetDataScalarTypeToUnsignedChar();
        imgPort->SetNumberOfScalarComponents(tmp.channels());
        imgPort->SetImportVoidPointer(tmp.data);
        imgPort->Update();

        // Initialize camera image inverter
        imgFlip         = vtkSmartPointer<vtkImageFlip>::New();
        imgFlip->SetInputData(imgPort->GetOutput());
        imgFlip->SetFilteredAxis(1);

        // Assign updated camera data to background actors
        actorBGL->SetInputData(imgFlip->GetOutput());
        actorBGR->SetInputData(imgFlip->GetOutput());

        // Set image to fill screen
        double* origin  = imgPort->GetOutput()->GetOrigin();
        double* spacing = imgPort->GetOutput()->GetSpacing();
        int* extent     = imgPort->GetOutput()->GetExtent();

        double xc       = origin[0] + 0.5*(extent[0] +
extent[1])*spacing[0];
        double yc       = origin[1] + 0.5*(extent[2] +
extent[3])*spacing[1];
        double xd       = (extent[1] - extent[0] + 1)*spacing[0];
        double yd       = (extent[3] - extent[2] + 1)*spacing[1];
        double d        = camBGL->GetDistance();
        camBGL->SetParallelScale(0.5*yd);
        camBGL->SetFocalPoint(xc,yc,0.0);
        camBGL->SetPosition(xc,yc,d);
        camBGR->SetParallelScale(0.5*yd);
        camBGR->SetFocalPoint(xc,yc,0.0);
        camBGR->SetPosition(xc,yc,d);

        // Begin rendering
        renWin->Render();
        iren->Initialize();

        cbc = vtkSmartPointer<vtkCallbackCommand>::New();
        functiontype func = &TimerCallback;
        cbc->SetCallback(func);
        cbc->SetClientData(this);
        iren->AddObserver(vtkCommand::TimerEvent, cbc);
        iren->CreateRepeatingTimer(50);
        iren->Start();
}


Any ideas? I would be incredibly thankful as this deadline is really pushing
me hard and I've spent a day on this problem already.

Did you forget imgFlip->Update()?

Message-ID: <CAAzeLU1ax77fSqmpihM+y8rc+3Dd9-ecYW+g4LRRwjcNeNG44w@mail.gmail.com>

Hi all,

I have an unstructured grid with some features in it. It contains
potential, joule heating and volume current in point data and geometryids
in cell data (see some part of the print below).

I am trying to represent volume current in my unstructured grid with the
code below, but it returns an error, does anybody know if what I am missing
or what is wrong?

Thank you

This is the last I read about this

http://vtk.1045678.n5.nabble.com/Python-3-x-support-td5723643.html

But I am also looking forward to this. Is there anything we could do to push
support for python 3 forward?

Wow, that actually worked. I didn't need to do that in the Python version at

Message-ID: <1406821194530-5728036.post@n5.nabble.com>

Here's my code (in scala): http://pastie.org/9434555

The class above creates a simple viewing window for structuredpoints data
it's initialized with. When switching images, my program currently unhooks
the ImageViewer and disposes of any references to it. It also calls the
end() method that you see in the code. The result is the ImageViewer and a
large number of the vtk objects are cleaned up by the garbage collector
EXCEPT the opengl lights, the renderer and renderwindow, and most
confusingly of all, the vtkpane. According to visualvm's heap dump
inspection, when vtkPanel is not being collected by the garbage collector,
there is no references to it on the java side to keep it alive. Even the
parent class ImageViewer is collected.

Am I missing some special command I need to call to get VtkPanel to
deallocate properly?

There is a Delete() method on it. But on Linux, vtkPanel leak to prevent a
crash.

  public void Delete() {
    if(rendering) {
      return;
    }
    rendering = true;
    // We prevent any further rendering

    if (this.getParent() != null) {
      this.getParent().remove(this);
    }
    // Free internal VTK objects
    ren = null;
    cam = null;
    lgt = null;
    // On linux we prefer to have a memory leak instead of a crash
    if(!rw.GetClassName().equals("vtkXOpenGLRenderWindow")) {
      rw = null;
    } else {
      System.out.println("The renderwindow has been kept arount to prevent
a crash");
    }
  }

If you remove the panel from its parent and call Delete(), that might solve
your premature exit of the delete method.

PS: Put the list back in the loop.

Right now I have it set to automated mode with this:

    vtk.vtkObject.JAVA_OBJECT_MANAGER.getAutoGarbageCollector().SetAutoGarbageCollection(true)
    vtk.vtkObject.JAVA_OBJECT_MANAGER.getAutoGarbageCollector().SetScheduleTime(1, 
TimeUnit.SECONDS)
    vtk.vtkObject.JAVA_OBJECT_MANAGER.getAutoGarbageCollector().SetDebug(true)

but I've tried with manually invoking the vtk GC, and I get the same results.

See, I'd been looking into that, but the print statement is never executed on 
my machine, which suggests to me that it escapes at `if(rendering) return;` 
always when I call Delete. Is there a way to force the panel to enter a state 
where at least its children (the renderer, renderwindow, etc) can be 
collected? They aren't at all unless I intentionally go through and manually 
delete them all, and even then I still have 4 or 5 objects leaked per panel 
created.

I do and it doesn't. I've also tried setting the pane to invisible to halt 
rendering, and nothing. You can see what I try in the end() method of the 
ImageViewer class I linked.

Hi, 

I'm using mac osx 10.9 " Mavericks", Im trying to run a code that include the following headers, 
#include "vtkConeSource.h"#include "vtkCylinderSource.h"
#include "vtkPolyData.h"#include "vtkPolyDataMapper.h"#include "vtkRenderWindow.h"#include "vtkCamera.h"#include "vtkActor.h"#include "vtkRenderer.h"#include "vtkRenderWindowInteractor.h"#include "vtkProperty.h"#include "vtkCallbackCommand.h"#include "vtkCommand.h"#include "vtkRendererCollection.h"#include "vtkFloatArray.h"#include "vtkCellArray.h"

When I try to run the code it displays the following

I installed vtk by following the steps in this link http://www.developers-life.com/configuring-and-compiling-vtk-6-1-on-mac-os-x-simple-example-of-vtk-usage.html
I do not know what is going wrong and I was not lucky to find any solution online. I hope someone can help me.

There has been some discussion about converting all of the python
tests and examples, which is a part of the process where extra
manpower would be a big asset.  I imagine that the conversion will
go something like this:

1) Someone will run 2to3 on all the python code, and then make
sure that it can be byte-compiled with python3 (it will be too early
at this stage to actually run the code, but making sure that it
byte-compiles will be a good first step).

2) Lots of people will then pick through the code to fix conversion
errors and to make sure that the code actually looks like good
python3 code.

3) Finally, someone will add some CMake magic to VTK so that if VTK
is built against python2, cmake will run 3to2 on all of these new python3
files and put the equivalent python2 code into the VTK build
directory.  This is the magic that is needed to make sure that VTK
will be able to support both python2 and python3.

So any assistance with the above process would be a big help.  In
particular, it would be very useful if someone could verify that item
(3) is even feasible: in the end it might be necessary to have hand-
written python2 and python3 exist side-by-side instead of using
automatic conversion.  It _should_ be feasible, since the VTK
tests used automated tcl-to-python conversion for many years,
and python3 to python2 should be much easier than tcl to python.

It sounds like you don't have your environment set up correctly.
I run OS X Lion, and I have VTK installed in "~/VTK" and I do both C++ and Python development using VTK.

My ".bash_profile" is:

export VTK=~/VTK
export PATH=$PATH:$VTK/bin
export PYTHONPATH=$PYTHONPATH:$VTK/lib/python2.7/site-packages
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$VTK/lib

export PATH=$PATH:/Applications/CMake.app/Contents/bin
export MANPATH=$MANPATH:/Applications/CMake.app/Contents/man

If that doesn't work, let us see your environment setup, and where you put VTK at. I tried to load your link and couldn't get to the page. It is VERY likely that the problem is on my end.

Hi,


I'm using mac osx 10.9 " Mavericks", Im trying to run a code that include the following headers,

#include "vtkConeSource.h"
#include "vtkCylinderSource.h"

#include "vtkPolyData.h"
#include "vtkPolyDataMapper.h"
#include "vtkRenderWindow.h"
#include "vtkCamera.h"

#include "vtkRendererCollection.h"
#include "vtkFloatArray.h"
#include "vtkCellArray.h"


When I try to run the code it displays the following

#include "vtkCylinderSource.h"

         ^

1 error generated.

make: *** [d3.o] Error 1


I installed vtk by following the steps in this link http://www.developers-life.com/configuring-and-compiling-vtk-6-1-on-mac-os-x-simple-example-of-vtk-usage.html


I do not know what is going wrong and I was not lucky to find any solution online. I hope someone can help me.



Thanks.

Ok - I'm not proficient at MPI development, but I tried to hack together a CMakeLists.txt file that worked on my system.
I used the CMakeLists.txt here as an example:
http://www.cmake.org/pipermail/cmake/2011-June/045037.html

I then tried to get an example to compile (http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filtering/Delaunay2D)

I used this as a CMakeLists.txt, and when I ran it with mpiexec, I got 8 copies of the tutorial:

cmake_minimum_required(VERSION 2.8)

project(Delaunay2D)

find_package(MPI REQUIRED)
find_package(VTK REQUIRED)

include_directories(${MPI_INCLUDE_PATH})
include(${VTK_USE_FILE})

add_executable(Delaunay2D MACOSX_BUNDLE Delaunay2D)

target_link_libraries(Delaunay2D ${MPI_LIBRARIES})

if(MPI_COMPILE_FLAGS)
  set_target_properties(Delaunay2D PROPERTIES COMPILE_FLAGS "${MPI_COMPILE_FLAGS}")
endif()

if(MPI_LINK_FLAGS)
  set_target_properties(Delaunay2D PROPERTIES LINK_FLAGS "${MPI_LINK_FLAGS}")

I'm not sure that anyone gets anything back when they type: `which vtk` - you might get something for `which vtkpython` if you built the Python wrappers though. I believe that the only issue I had with Mavericks was that there was an advanced option that I had to remove from an option. This is discussed here: http://public.kitware.com/pipermail/vtkusers/2014-March/083368.html. If you don't remove the -fobjc-gc from VTK_REQUIRED_OBJCXX_FLAGS, you'll have another confusing problem.

For what it's worth, my ccmake line was something like this:
ccmake .. -Wno_dev -DCMAKE_INSTALL_PREFIX=~/VTK
(and then I changed some stuff in the interface, mentioned in the link above)
The ccmake line you used doesn't look like there is anything wrong with it, but I didn't personally try it.

Probably the best way to check out if you're set up correctly is to download one of the example programs from the VTK wiki, such as:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/SolidClip
and just follow the directions. They're pretty painless to download and try, and it is probably the best way to start learning it. If you're very new - like me - I would also recommend the User's Guide. A few dollars spent now is probably worth many many many frustrating hours staring at your terminal.
