This takes a vertex list, generates face normals and then uses the face normals to generate vertex normals.
In short, its a mesh-auto-smoothinator which will be a keystone in my content pipeline. The example mesh shows a side-by-side of auto-normals and then a smoothinated mesh with smooth areas and hard edges maintained.
(Also, this is a super-secret clue on what the next feature is.)
The LDR mesh importer loads LDR primitive objects. It throws away the line type data although I'm seriously considering processing this at a later date, since I'd love to have good wireframes.
The Mesh Import was reasonably quick at one 200 line class. Although there is an obvious extraction refactor to split the code up I found it was manageable enough at its size so have let it be.
The Mesh Post Processing was aroud 500 lines of code, and rammed into a single class with about four or five responsibilities.
The system relies on a dozen or so unit tests, although coverage isn't exhaustive.

- Quantize the mesh so that similar vertices are identical
- Build a tringle list from the vertex data
- Unify normals by rewinding data
- Calculate face normals
- Autosmooth to generate vertex normals
