Abstract
A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. Cartoon lighting and other non-photorealistic effects can be produced by using a lighting calculation to produce a parameter other than color or opacity for use in a later modification of a color or opacity value. In more detail, the example embodiment uses the lighting calculation to generate texture coordinates used in a texture mapping operation. The texture mapping operation allows lighting computation results to select between brush strokes for cartoon lighting and other effects. The resulting dynamic cartoon lighting animation can be performed on a low cost platform such as a home video game system or personal computer.
