Tx JR!
My code is already working from STL to POV even with the color subset of STL.
In fact I have to add the surface calculation to the loops from triangle to
smooth_triangle, I'll take a look at your system. But first I also want to
translate the color, as I already do with the triangles, dividing groups of
differently colored meshes. This way my translator will also become faster
because the loops are compact and short on small meshes.
(between different colors I don't want smooth).
In the center STL, on the left the current smooth routine, on the right the
simple triangle mesh. Thank you!
