Hello,<br>
<br>
I have recently refactored ITK's TIFFImageIO mostly for improving reading, but it supports writing 3D images as multi-paged tiffs. You can utilized ITK ImageIO by using ITK's VTK bridge module [1]. Alternatively, you can look at ITK's implementation as see about porting it to VTK[2]. I believe the writing method still has an evident heritage from VTK.<br>
<br>
I am not a big fan for 3D tiffs because there is no standard way to store z-spacing and image origin.<br>

As I need to modify the angle from which the unrolling is starting I would<br>
use the sophisticated solution you advise.<br>
If I understand correctly the starting reslice axes are a 4x4 matrix<br>
(-1,0,0,center[0],0,-1,0,center[1],0,0,1,center[2],0,0,0,0).<br>
If I need to apply an angle, I could use only the 3x3 matrix<br>
(-1,0,0,0,-1,0,0,0,1).<br>
Can you tell me if I am right?<br>

Yes, the 3x3 matrix controls the orientation of the cylinder, and<br>
the final column is where you want the center to be.<br>
<br>
However: the bottom row should always be (0,0,0,1). And I'm<br>
not sure why you put in the "-1"s. Is there a reason why you want<br>
to rotate by 180 degrees?<br>

Hey Bradley,<br>
Thanks for your reply, I'll have a look at the itk code.<br>
I just have some 3d tiff ct data and after soon processing, my first thought was to just save it in its original format.<br>
Thanks for your remark re. spacing and origin; I was about to send an email to the person who gave me the ct data, to ask about this data. I now feel more confident that my code didn't screw up these numbers ;-)<br>

<br>
I can add a little bit more information about how to set the 3x3 matrix.<br>
The third column of the 3x3 matrix must be a unit vector that points<br>
along the axis of the cylinder. The first and second columns must<br>
be perpendicular to the third axis, and must be perpendicular to each<br>
other (if they aren't, then the matrix isn't a rotation matrix).<br>
<br>
The method vtkMath::Perpendiculars() can be used to compute the<br>
three columns for the 3x3 matrix, if you know the axis of the cylinder.<br>
<br>

I put in the "-1"s because I reuse the matrix presented in your code<br>
(rotate.SetResliceAxesDirectionCosines(<br>
-1, 0, 0,<br>
0, -1, 0,<br>
0, 0, 1 ) )<br>
Shouldn't I do this?<br>

No, this isn't something that should be blindly copied. I added those -1's<br>
because<br>
it set up the cylinder orientation properly for my data. You have<br>
different data, so<br>
you will probably need a different matrix. Does that make sense?<br>

Hello,<br>
I want to get the texture value from a cell!<br>
I have the cellid as result of intersectWithLine.<br>
<br>
After I get the list of vertices of the cell:<br>
vtkIdList* nghList = vtkIdList::New();<br>
source->GetCellPoints(cellId, nghList);<br>
I iterate through the points in order to get their texture coordinates<br>
and interpolate them in the intersection position.<br>
Then with the (interpolated) texture coordinates, access the texture<br>
image to get the RGB point color!<br>
<br>
Is there a method faster than that?<br>
<br>
Thank you<br>

That makes definitely sense.<br>
Apart this rotation and the variables radialSize and r, I got the impression<br>
that the rest of the code doesn't depend on the data. Do you agree with<br>
that?<br>
Thanks again<br>

In addition to those, the code also assumes that the center of the cylinder<br>
is at the center of the image, which might not be true for your data.<br>
<br>
That's why I said that you might want to use the full 4x4 ResliceAxes matrix<br>
instead of just using SetResliceAxesDirectionCosines. If you use a 4x4<br>
matrix, you can use the 4th column of the matrix to adjust the center.<br>

Hi Marco,<br>
<br>
Texture coordinates are stored in an array in a vtkDataSet's<br>
vtkPointData object. Say you have a vtkPolyData with texture<br>
coordinates. To access it, you would do something like<br>
<br>
vtkPointData* pd = polyData->GetPointData();<br>
vtkDataArray* tcoords = pd->GetTCoords();<br>
<br>
// Let's assume the tcoords are in a vtkFloatArray<br>
vtkFloatArray* floatTcoords = vtkFloatArray::SafeDownCast(tcoords);<br>
if (floatTCoords)<br>
{<br>
float texCoord[3];<br>
floatTcoords->GetTupleValue(pointId, texCoord);<br>
<br>
// do something with texCoord<br>
}<br>
<br>
I hope that helps,<br>
Cory<br>

Hello<br>
I was able to retrieve the tcoords for my Points.<br>
Now I'm trying to access the texture image to get the rgb value for that<br>

Is possible to use directly the tcoords to do that? or I have to compute<br>
the pixel coordinate with a transformation?<br>

I don't know of a class method that lets you look up the color given a<br>
texture coordinate. I think you'll have to compute the pixel<br>
coordinate, which shouldn't be too hard.<br>

Hi there,<br>
looks like the problem was unrelated to VTK or Qt themselves, but to the<br>
way we were trying to create the OS X bundle through our CMakeLists.<br>
<br>
Attached is a CMakeLists that should solve the issue.<br>
<br>
Please note that you will need to change the {VTK_BIN_PATH} for the<br>
location where your VTK binaries reside, for example<br>
/Users/your_username/Development/Binaries/VTK6/bin<br>

Hi all,<br>
Yesterday I started exploring the options to draw 2d graphs in VTK.<br>
<br>
Why does<br>
m_pChart->GetPlot(0)->SetInputData(0);<br>
not remove the graph from my chart?<br>
<br>
I am currently using<br>
vtkTable* table = m_pChart->GetPlot(0)->GetInput();if( 0 != table ){??? while( 0? < table->GetNumberOfRows() )??? {??????? table->RemoveRow(0);????}}<br>
m_pChart->GetPlot(0)->GetData()->Modified(); // <- required!<br>
This works, but complains about trying to draw a line with less than 2 points.<br>
Thanks - Maarten<br>

That isn't how the API was designed, you can call remove for a plot,<br>
or clear all plots.<br>

Unless the data is marked as modified then the plot is cached, and it<br>
would be slow to rebuild on every render. This is pretty common in the<br>
VTK API, if an object is not marked as modified it is not surprising.<br>
I guess you might expect SetInputData on the plot to mark that as<br>
modified, which could be a bug in that method.<br>
<br>
Hope that makes it clearer, it has been a while since I went through<br>
all of this logic, and it is possible we still have one or two bugs<br>
lurking in there.<br>

In the debugger, I followed the call<br>
m_pChart->GetPlot(0)->SetInputData(0);<br>
all the way into vtkContextMapper2D::SetInputConnection()? and it seems to invoke the calls inputs->SetNumberOfInformationObjects(0); and this->Modified().<br>
So although Modified() is called when the input is removed, I think the scene is not re-rendered (I don't get a warning re. a mapper w/o input either (what other mappers do)).<br>
Turning the visibility on/off using SetVisible() works fine. But I find it weird that the data is still dangling.(I don't want to remove the plot, because that would mean I'll have to keep track of all the plot ids.)<br>
So I think my problem is gone, as long as I don't try to understand what is going on. ;-)<br>

Subject: [vtkusers] Issues with VTK Delaunay 2D for simple cases<br>

Hi,<br>
<br>
I am using vtkDelaunay2D for triangulation of cells in 3D based on lines and<br>
points. Each one of the cells prior to triangulation has the boundary of a<br>
triangle. Obviously, there are other points and lines given within the<br>
triangle boundary, so there is something for the algorithm to triangulate.<br>
Here are few bullet points describing what I am doing.<br>
<br>
1. I use a transform to transform each cell to the xy plane prior to running<br>
vtkDelaunay2D<br>
<br>
2. Each cell has a triangular boundary, but there are other lines/points<br>
within the boundary<br>
<br>
3. I am doing a constrained delaunay (i.e. I am providing the triangular<br>
boundary, so that cells can not be added outside the cell boundary)<br>
<br>
This is working well besides what seems to be the easiest triangulations. By<br>
easiest, I mean that the cell to be retriangulated lies in the xy plane, zx<br>
plane, or yz plane prior to the transformation. Something interesting to<br>
note, is if I take the transformed cell to be triangulated and I restrict<br>
the precision of the points in the cell to 6 or 7 digits, the triangulation<br>
works for any input cell. However, I don't want to have to restrict the<br>
precision of the cell points, as that may cause issues later.<br>
<br>
I was wondering if anyone has ever seen similar issues, or if anyone has any<br>
insight into this?<br>
<br>
Thanks in advance,<br>
<br>
Adam<br>

I recompiled VTK in debug mode and the vtkOrientationMarkerWidget segfaults<br>
in line 350 of vtkOrientationMarkerWidget.cxx (see screenshot).<br>
<br>
I'm using VTK 6.2 from Git, Qt5, GCC 4.9, C++14. The current code that is<br>
causing the segfault is:<br>
<br>
VTKViewer::VTKViewer(QWidget *parent) : QWidget(parent){<br>
QVTKWidget *qvtkwidget = new QVTKWidget;<br>
qvtkwidget->setSizePolicy(QSizePolicy::MinimumExpanding,<br>
QSizePolicy::MinimumExpanding);<br>
<br>
auto renderer = vtkSmartPointer<vtkRenderer>::New();<br>
<br>
vtkRenderWindow *renderWindow = qvtkwidget->GetRenderWindow();<br>
renderWindow->AddRenderer(renderer);<br>
<br>
auto axes = vtkSmartPointer<vtkAxesActor>::New();<br>
axes->SetXAxisLabelText("x");<br>
axes->SetYAxisLabelText("y");<br>
axes->SetZAxisLabelText("z");<br>
<br>
auto orientationMarker = vtkSmartPointer<vtkOrientationMarkerWidget>::New();<br>
orientationMarker->SetInteractor(qvtkwidget->GetInteractor());<br>
orientationMarker->SetOrientationMarker(axes);<br>
orientationMarker->SetEnabled(1);}<br>
<br>
Could you please tell me why this implementation is failing?<br>
<br>
Appreciate any help,<br>

VTK 6.1 / Nvidia<br>

Hi all,<br>
<br>
I am dealing with stereo rendering pb on VTK6 and Qt5.<br>
<br>
The attached code sample correctly displays stereo rendering<br>
(quad_buffer/crystal eyes, but also other stereo types e.g horizontal_split<br>
or anaglyph) when compiled with QT4. It works with VTK6.0 and VTK6.1<br>
<br>
The same code compiled with QT5 (5.3) and VTK6.1 does not render<br>
quad_buffer stereo (anaglyph and horizontal_split stereo are OK).<br>
<br>
The host runs FedoraCore20, with the distrib version of Nvidia drivers<br>
(331-39-2). Both binaries are linked with the same opengl dirvers.<br>
<br>
It is a known issue with quand_buffer rendering with VTK6.1 and QT5?<br>
Or?. what did I wrong ?<br>
<br>
Here is the code:<br>

Hi all,<br>
I happened to be looking at the source of the vtkContextInteractorStyle class.<br>
In the OnKeyPress() and OnKeyRelease() functions I see the folowwing:<br>
vtkVector2i position(this->Interactor->GetEventPosition()[0],??????????????????????????????? this->Interactor->GetEventPosition()[0]);<br>
which to me looks wrong.<br>
Not sure whether one of the vtk developers has already been made aware of this.<br>
<br>

Hi all,<br>
I would like to know how I would select a vtkPlot (better: vtkPlotLine) object in a vtkChart (better: vtkChartXY)?<br>
I get the impression that only points can be selected in a vtkContextScene. However, I have two vertical lines each with two (bottom and top) points, to indicate a (threshold) range, and that I would like to move left and right with my mouse.Would this be possible (or should I go back to something like QCustomPlot)?<br>
<br>
Thanks - Maarten<br>
