The surface normals are obtained from the drawingInfo object returned by the object parser. These are already interpolated between the normals of the shared vertices. This means that the corners between faces share the same normal, giving us a smooth transition between the faces, contrary to if the normals were just those from the faces, which would give a sudden jump.
