Hello,
Once I posted my problem on this mailing list, but no one answered to that post.
I have a problem of coordinate system mis-match between generated
polydata (vtkMarchingCubes) and image data (DICOM).
It seems like this is not just problem of translation (offset), there
is a mis-match in rotation as well.
So I am wondering how I can align them.
Here is the code block which I am using:
vtkMarchingCubes* surfaceCreator = vtkMarchingCubes::New();
surfaceCreator->ReleaseDataFlagOn();
surfaceCreator->SetInput(m_FirstImage->GetVtkImageData());
surfaceCreator->SetValue(0, m_sliderThreshold->lowerValue());
surfaceCreator->SetValue(1, m_sliderThreshold->upperValue());
surfaceCreator->ComputeNormalsOff();
surfaceCreator->ComputeGradientsOff();
surfaceCreator->ComputeScalarsOff();
surfaceCreator->Update();
mitk::Surface::Pointer surface = mitk::Surface::New();
surface->SetVtkPolyData(surfaceCreator->GetOutput());
mitk::DataNode::Pointer surfaceNode = mitk::DataNode::New();
surfaceNode->SetData(surface);
m_DataStorage->Add(surfaceNode);
If you anyone has good idea, just let me know.
