Andre, nothing specific, but does your polyhedron get displayed correctly in
the Polyhedron viewer demo or does it assert there too?
I had a similar problem last month trying to read .obj files before I
realized I was using the wrong kernel ...

Hello,
sorry to bump my own question.
But does anybody know what these assertions mean and how I can prevent them?
Or how I can alternatively build a convex Nef polyhedron with a fast kernel,
avoiding the assertions in "polyhedron_3_to_nef_3"?
Thanks a lot.
Best regards,
Andre
