Summary0008233: Volume rendering issues
DescriptionReported by Patrick Shinpaugh (see below). I have the dataset.

Hi Berk,
The dataset is approximately 640MB and can be downloaded from

  http://snoid.sv.vt.edu/~shpatric/files/TurbDuctNetgen-Re1500-fixed.tar.bz2 [^]

It represents fluid flow down a shaft with an obstruction - it is a student's dataset so I am not entirely familiar with the problem.

The latest script can be downloaded from

  http://snoid.sv.vt.edu/~shpatric/files/TurbDuctNetgen-Re1500-fixed.pv.py [^]

I did actually find a workaround but I don't think it should be necessary - it no longer segfaults but has other issues (?):


view.StillRender()
view.ResetCamera()
view.StillRender()
rep.Representation = 4 # Volume --> CRASH no longer

view.StillRender()
view.ResetCamera()
view.StillRender()

With this "fix" it shows the first frame (based on the view.ViewTime I set) which looks like it is a surface and not a volume and then blank window after that for all of the 900 other timeframes.

Please let me know if you have any questions or need anything to solve any issues.

Thanks,
Pat

This seems to work now. Update version of the test python script is attached (newscript.py). The old script may now work since it does not setup the opacity and color lookup tables correctly.

This also worked for me. Tested local server, windows, trunk.

I was seeing crashes, however, that we determined had to do with the array lengths not matching up over time.
