How does one convert an UnstructuredGrid (`*.vtu`) file to ImageData (`*.vti`)? Is there a resampling filter I can use?

@mwestphal When I use this, I get a blank outline and no surface or volume.
FYI, my input data to `ResampleToImage` is an isosurface (generated with `Contour` filter) that I then box clipped some portions out, which turned my origina `lmageData` to `UnstructuredGrid`.

RessampleToImage is bad with surfaces, try GaussianRessampling instead.

That doesn’t seem to work either ☹

@mwestphal I’m unable to share my data at this moment, but I am having our company establish and NDA so I can share data.
