I'm slowly clearing my head
For an excellent result the code must have at least 3 steps
1) (already done), calculation of the average of the normals affecting the
point.
2) Correcting the weight of the normals per point if they also come from
triangles with a large surface area
3) Corrective of the normals if the adjacent triangles have an inclination
between them that tends to approach 90 degrees
