[vtkusers] Question about vtkProbeFilter with unstructuredgrid with Polyhedron cells

[Gerrick Bivins]

I ended up taking a different approach for what I was trying to do with the probe.
Basically used mask points instead to sample the data.

If you can provide, a small, compilable example that illustrates the issue I'm sure we can help.

Hi All,
I'm trying to debug a problem with one of my pipelines that uses a probe filter.
It worked properly for the structured grids and also one of the sample unstructured grids from the VTK dataset but fails with
one of our generated grids. By fail I mean, the valid points mask array has many invalid points
even though the input to the probefilter fits entirely in the source grid.
Is the problem that I have polyhedron cells?
If so, is there a special filter to probe unstructured grids with polyhedron cells? vtkProbePolyhedron seems
to only be for surface meshes (polydata).
Thanks for any pointers here.
Gerrick
