[Paraview-developers] Visualization field data at Gauss Points

[David E DeMarle]

Seems we can interpolate onto the points, but I am not aware of anything
in-built that interpolates from them.

For that your approach seems reasonable as would a splatting technique. I
might suggest apply a resample filter to get the interpolated values back
onto the original unstructured mesh. In either case the interpolation will
be pretty simplistic.
