There was a problem hiding this comment.
I've added example docs and tests, otherwise I think it's good to merge. Thanks for your work!

Overview
This introduces a new
probefilter based onvtkProbeFilterper pyvista/pyvista-support#203 and has some massive improvements to theinterpolatefilter.cc @jrwrigh
Details
interpolatefilter was wildly inefficient for large datasets and required the use of an intermediateUniformGridduring the interpolation. This removes that intermediate step so that the gaussian interpolation happens directly on the calling mesh. This has drastic performance differences when interpolating large meshes and yields the exact same results for our example use cases. The arguments for the method have rightfully changed (DEPRECATION), but it's well worth the improvement
