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.
