Re: [Paraview] Selecting volume rendering causes output to vanish
500^3 should not be an issue. Still worth seeing if you can get the test data from wavelet source to display as a sanity check. Another thing that occasionally occurs, if the there is one or two extremely large outlying values in your dataset (say from writing random unitialized memory), the default transfer function makes the dataset invisible. Would be worth checking the range of your data and experimenting with transfer function as well.

Re: [Paraview] Selecting volume rendering causes output to vanish
Probably the content isn't amenable to volume rendering. To be so, the unstructured grid has to have volumetric cells in it (tets, voxels, etc). If it just has polys or lines or points in it, they won't appear. You'll have to resample of splat onto the data onto a volumetric grid in that case. David E DeMarle Kitware, Inc.

If Bunyk ray cast doesn't work some thing strange is going on as that is a software(non gpu) algorithm and should always work. Can you get anything to show up using a small test data? For example create a wavelet source and apply a threshold (use default values) to convert to unstructured data. If that works maybe something with your input data, or size of it. It's a 500 by 500 by 500 grid of floats - is that too big?

One of those usually works depending on what the cause of the issue is. I have both of those set - no luck.

I have an unstructured grid file that opens and displays in Surface Rendering mode. If I switch to Volume Rendering, I don't see any output. Any ideas? Thanks. -jeff ___
