That method doesn't work (at least for me and one other) for polyhedron. You have to use the "face stream" method described here:<br>

Not sure if it's a bug or "works as designed".<br>
See wiki entry for example of how to make it work:<br>

This question is more appropriate for the vtk-users mailing list.<br>
