Summary0014237: Concave polyhedron not likely to be clipped correctly.
DescriptionBecause the InternalContour method of vtkPolyhedron does not perform any refinement, it is possible to construct a concave polyhedron that, when clipped or contoured, will have self-intersecting faces.

The mean-value-coordinates interpolant does not guarantee convexity except on convex planar polygonal facets.

The attached example (which also appears to be incorrectly triangulated) produces self-intersecting faces when isovolumed with range [1.5,6.0].
TagsNo tags attached.

Tetrahedralize filter also gives wrong results on this polyhedral cell (inside of U-shape also gets cells).
