Web(2) Computing surface normals from weighted face normals: Once you have the weighted face normal for each face, then for each vertex you simply sum up all the weighted face normals for the faces which contain that vertices. Then you normalize the result (ie: scale it to length 1.0), and that will be the surface normal at that vertex.
