[vtkusers] AND-filter for vtkPolyData (was extract/selectcoincident points/cells)

[alex Dowson]

Hi

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

http://www.vtk.org/doc/nightly/html/classvtkBooleanOperationPolyDataFilter.html

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
