Thanks! That did it! Next problem, along similar lines. I want to simply volume render a vtk file I have. If I do everything from within the paraview app, it works fine. But if I try to do the following from the python shell (or pvpython) it seg faults on me:
>>> reader=LegacyVTKReader(FileNames="/home/battams/model.vtk") >>> Show(reader) >>> SetDisplayProperties(reader,Representation='Volume') Here's the error I get in my terminal: ERROR: In /home/battams/Builds/Paraview3/ParaView3/VTK/VolumeRendering/vtkFixedPointVolumeRayCastMapper.cxx, line 1467 vtkFixedPointVolumeRayCastMapper (0x7fc7b7368010): Cell Scalars not supported [3] Segmentation fault paraview It looks to me like the problem is my model because of the "Cell scalars not supported" message. But I can load/view it fine if I just use the ParaView GUI. Apologies in advance if I'm making some sort of stupid beginner mistake... ~~Karl On Fri, Aug 21, 2009 at 11:08 AM, Utkarsh Ayachit < utkarsh.ayac...@kitware.com> wrote: > When you creating the readers using python shell from the GUI (not > pvpython or pvbatch), it's recommended that you set the FileName in > the constructor itself.
