Have you tried CSG Boolean filter in VTK ?   Check this class


Also you can use implicit boolean operation filter for that.

Dear mailing list members,

Is there a kind of AND-filter for vtkPolyData-meshes which I could use
to extract/select coincident points/cells of two meshes?

Thanks for any hints or help
