[vtkusers] Removing cells inside solids !

[David.Pont at ForestResearch.co.nz]

Hi Sebastien,
   what about using vtkFeatureEdges with BoundaryEdgesOn (and the others
off) on the 'square', before extruding?

Sorry for this repost but we never had any answers and it is now becoming a
critical issue for us.

Is there a filter that would remove the facets inside a solid ?

Let say i have a square formed with two triangles. (See attached image )
I extrude this square to get a cube.
Because ALL edges are extruded to produce facets, the resulting cube will
have an unacessary internal diagonal facet.

Is there a vtkFilter that could remove those internal topologies ?

Thanks !
