Hi
Is there a vtkIsoVolume example that I can refer to? When I open a vtu file
in ParaView and apply the "Iso Volume" filter to it, I am able to see the
Iso Volume. I tried to replicate that in my VTK application but I ran into
"Unable to allocate memory" error.
Here's the code snippet ( I verified using the debugger that ParaView uses
the same values for the SetInputArrayToProcess):
vtkXMLUnstructuredGridReader* reader = vtkXMLUnstructuredGridReader::New();
reader->SetFileName("C://MyFile.vtu");
vtkIsoVolume* myIsoVolume = vtkIsoVolume::New();
myIsoVolume ->SetInput((vtkDataSet*)reader->GetOutput());
myIsoVolume
->SetInputArrayToProcess(0,0,0,vtkDataObject::FIELD_ASSOCIATION_POINTS,"Pressure");
myIsoVolume ->ThresholdBetween(-100,100);
myIsoVolume ->Update();
