Hello Giovanni!

Your results are already looking very good! :-) Congratulations for figuring out
this kind of translation. (I have been busy working on the 'opposite'
translation-- POV-ray objects to STL.)

A little utility called 'stl2pov' was mentioned. I remember it from years ago.
It is still available here, although it apparently runs in Python(?). It might
give you some ideas and suggestions about your problem.

By the way, I also thought that the normals of triangles are direction vectors
of 'unit length' by default, not smaller or larger, but I could be wrong.

I am looking forward to seeing how you solve your too-smooth problem; I wish
that I could offer some suggestions. Some of this triangle stuff is outside my
knowledge.  *If* the triangle normals are all unit length, perhaps your summing
operation could be made to eliminate some of the identical normals on large flat
areas, which might reduce their contribution-- and make the smoothness less
smooth. (?)
