Face weighted vertex normals and normal maps
WebNormals can be interpolated by OpenGL across each vertex of a face(triangle) so you can calculate the reflected light per pixel not per vertex, hence giving a more accurate result. Normal Mapping: on the … http://wiki.polycount.com/wiki/Face_weighted_normals

If your model is smooth, then the normal for a vertex should be the same as for neighbour points. That means that you compute a weighted normal from normals in near points/triangles. A cube is not smooth, so the normal for each face is independant of ...
