Knowing the difference between world coordinates and object coordinates is important when using mapping techniques. In object coordinates the origin and coordinate axes remain fixed relative to an object no matter how the objectís position and orientation change. Most mapping techniques use object coordinates. Normally, if a teapotís spout is painted yellow, the spout should remain yellow as the teapot flies and tumbles through space. When using world coordinates, the pattern shifts on the object as the object moves through space.
