Hi everyone,<br><br>I know this question has been asked before but I could not find an answer that could have helped me, so I am asking again.<br><br>Well... I am trying to get the classic 3 orthogonal slices through a volume. I know the vtkImageViewer2 provides this functionality but I cannot use that component unfortunately.
<br><br>I was trying to use the vtkImageReslicer to get the XZ plane through the volume. <br><br>So, I tried setting up the matrix as follows:<br><br>vtkImageReslice * slicer = vtkImageReslice::New();<br>slicer->SetInput(imageChangeInformationP->GetOutput());
<br>slicer->SetResliceAxesDirectionCosines(1, 0, 0, 0, 0, 1, 0, -1, 0);<br><br>Is this matrix correct if I want to get the XZ plane out of the volume? I ask because some of the slices in the beginning and end seem bogus. The vtkImageViewer2 does not show them when I set the orientation to XZ in the vtk viewer.
<br><br>Also, I noticed that the vtkImageViewer2 displays the volume nicely with correct aspect ratio and all that... So, I tried using:<br><br>slicer->SetOutputSpacing(1.0, 1.0, 1.0);<br><br>This was shown in the example. However, this changes my extents and the number of Z slices reduces.
<br><br>I was wondering if someone can help me determine the correct matrix for extracting these planes.<br><br>Thanks,<br><br>Anja
