Clip Closed Surface filter should pass data arrays

[GregVernon]

I have a dataset that is the surface of a volume – only the surface of the volume is exported to PVD. The dataset has simulation results embedded as cell and/or point data. I want to do a Clip Closed Surface filter so that it “looks” solid. However, this filter seems to remove all point and cell data.

I realize that this is probably a design decision, since no data exists inside the boundary surface, but it would seem that ParaView could simply assign NaN values on the generated surface(s)?

Sphere source, colored by normals

Clip Closed Surface, no datasets

Standard Clip, keeps datasets

Desired result, NaN assigned to closing surface

This seems simple to add tbh. A few hours of work.

I would like to second this request.
