Adding normals to the library

[Nicola]

The "Smooth Shading and Edge Split" algorithm from Nicola's post is relatively straightforward. The problem is that it works rather poorly with some LDraw geometry.

You're right, but i was just talking about normals in general, i was not not suggesting to use this tecnique to mass-add normals to the ldraw library. To do that i think one of the two methods you mentioned are the way to go.
