\brief Builds smooth vertex normals over a mesh.

- "smooth" because smoothing groups are not supported here
|

|
|
- takes angles into account for correct cube normals computation

To use 32bit indices pass a pointer in dFaces and set wFaces to zero. Alternatively pass a pointer to
|
||
|
|
wFaces and set dFaces to zero.
