I know that it is a vector perpendicular to a surface, but is it a group of coordinates or a group of angles? And would it be the normal I would use to rotate an object so it is parallel with the surface? "Oh no, it's true! I'm a love magnet!" Calvin from Calvin and Hobbes My name's Anonymous_Alcoholic.
