Hi Charles,

Thanks for your reply! You're the only one who replied, and no, I never got
an answer to my question. I had to leave Triscan. I still wonder how it's
possible for the program to create a raw file that is *not* compatible with
the Povray mesh syntax, as if the vertices are not stored in the cartesian
3d space! (I think it's called).

Well, I wanted the tesselated objects back in Povray - only - because I have
many ideas for manipulating them in SDL (Povray's scene description
language). Meshes are much more flexible than primitives, though not as
...smooth.

I see that Jerome Grimbert is working on a tesselation patch coded in C,
which means it'll be faster but not accessible in SDL as such. But the
important thing will be to get an output of all vertices and faces. I hope
it will soon be official part of Pov.

Regards,
Hugo
