Thanks, but I my code with normals works fine, see my code and render pictures
Furthermore, even if I am able to calculate the normals, in the binary STL files
to be converted, they are already present and available.
The question is about the level of the smooth.
I would like to get the effect of a smaller radius in the rounding illusion.
As Bald Eagle suggested I'm trying to work on the single "weight" of normals in
their average for each point (which creates the smooth effect) , considering
the size of each triangle.
I hope I have explained myself, I have little command of English, and the
question is not very simple
