Abstract

A system for generating blend values (18) for three-dimensional graphic rendering includes a first register (12), a second register (14), a third register (15), and index creation unit (16), a blend value generation unit (18) and a blending unit (20). The first register receives and stores color pixel data, the second register receives and stores a depth perspective component, and the third register receives and stores fog color data.
