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

Thank you for making ParaView! It is a tool we use 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.
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.
This resampling works fine if you use the Tetrahedralize filter
instead of the "Clean to Grid" filter.
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.
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).
Thanks,
Russ
