Theory is fine, but understand it and unite with the existing code is a
different story.

I've been trying other methods to "calculate" the normal, like using the same
points of the original object with a differente radius, but it generates
artifacts as this picture shows.

I wonder if even getting correctly calculate the normal vector could it apply to
other kinds of objects like the surface of Klein post <a

I suppose you know what I mean, the normals should be to reverse as the surface
is folded in on itself generating more artifacts like these. Or not?
