Thanks for the information!

Yes, the representation might be easyer with triangles, but the files with the
triangles might be a little bit bigger than the nurbs description. Once I
created
a TIE fighter with Rhino. The size was about 12 MB. The PovRay meshfile
was about 125 MB and it took some time to parse it. (I know that there is
a utility by Chris Colefax which reduces the number of triangles.)
