Because there are so many possibilities, texture mapping is
a fairly large, complex subject, and you must make several programming
choices when using it. For instance, you can map textures to surfaces
made of a set of polygons or to curved surfaces, and you can repeat a
texture in one or both directions to cover the surface. A texture can
even be one-dimensional. In addition, you can automatically map a
texture onto an object in such a way that the texture indicates
contours or other properties of the item being viewed.
