<div dir="ltr">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.</div>

That's it! I created an unstructured grid of points from a data file
using VTK. I'll see about resampling to volumetric grid. Thanks.<br>

Hmm. 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.<br>
<br>
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.<br>

It's a 500 by 500 by 500 grid of floats - is that
too big?

2 things to try: set the remote render
threshold to zero, and if that doesn't
get it to show up, change the mapper to
Bunyk ray cast. One of those usually
works depending on what the cause of the
issue is.<br>

Hi. 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?<br>
<br>
Thanks.<br>
