Claim One:
1. In a system having a rendering pipeline for rendering an image that includes a primitive to which texture maps can be applied, wherein the rendering pipeline includes one or more texture units, a method for applying data obtained from texture maps to a pixel of a frame using the one or more texture units, the method comprising the acts of: storing destination pixel data in a destination frame buffer; passing at least a first set of texture coordinates associated with the pixel to a texture unit, wherein said first set of texture coordinates is associated with a first texture map; obtaining first texture data from said first texture map, wherein said first texture data corresponds to the pixel; passing a second set of texture coordinates associated with the pixel to a texture unit, wherein said second set of texture coordinates is associated with a second texture map; obtaining second texture data from said second texture map, wherein said second texture data corresponds to the pixel; and modifying said destination pixel data to obtain composite texture data that is used to refresh a display screen.
