I confirm this in ParaView 3.12.0 (git version) (linux 64-bit).<br>

all the time, and I'm using it to teach my visualization class.
Students with Windows, Mac, and Linux are all able to do quite
effective visualizations with it.

I attach a Paraview State file that demonstrates a resampling
issue in ParaView. This may be a problem in VTK, not sure.
<br>
<br>
The problem is that when you resample a lower-resolution 3D volume
that has gone through the "Clean to Grid" filter and then a
Transform filter, a "Resample with Dataset" filter misses samples
in the middle of the volume.
<br>
<br>
This resampling works fine if you use the Tetrahedralize filter
instead of the "Clean to Grid" filter.
<br>
<br>
I encountered this while merging PET, CT, and MRI data sets to
produce a homework exercise using ParaView for my visualization
class. I can work around it using Tetrahedralize, but wanted to
let people know that there is an issue.
<br>
<br>
In the attached file, if you right-click on the Transform filter
and change its input to Tetrahedralize, the holes in the middle go
away (as they should).
<br>
<br>
Thanks,
<br>
