How can I extract cell IDs during point dataset interpolation process?


I use filter to interpolate scalar field data from a 3D field (VTK file) into a 2D plane grid (STL file).

In this case, I think probably small amount of cells (or points) of a 3D field may be used for the interpolation process.
(only cells near 2D plane may be involved for the process.)

Then, can I get this specific cell IDs?

I’m trying to find methods in paraview.simple such as pointDatasetInterpolator1.GetDataInformation().GetCellDataInformation() …
But, it is hard to do it.

Can I get some ideas?

Thanks in advance.
