[vtk-developers] vtkUGrid InsertNextCell throws error

[Gerrick Bivins]

That method doesn't work (at least for me and one other) for polyhedron. You have to use the "face stream" method described here:
http://www.vtk.org/Wiki/VTK/Polyhedron_Support

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

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