thanks, I don't know if I am right, but I think I understand that with that
function I can automatically correct rendering errors. Is that right?
I'd like PovRay to intervene by filtering out nonexistent elements INTO my file,
thus saving me from having to filter out all the normals or zero-surface
triangles and recompile its file.
These things happen because with double float sometimes very small values
​​differ from each other and everything is fine, but then, when for
various reasons I happen to work and pass values ​​in single
precision, the problem arises.
I can fix them, but it would be faster if when POV found them he cleaned the
file for me
