Bumpmapping is an advanced multitexture blending technique that can be used

to render the appearance of rough, bumpy surfaces. The bump map itself is a

texture that stores the perturbation data. Bumpmapping requires two

textures, actually. One is an environment map, which contains the lights

that you see in the scene. The other is the actual bumpmapping, which

contain values (stored as du and dv) used to "bump" the environment maps

texture coordinates. Some bumpmaps also contain luminance values to control

the "shininess" of a particular texel.
