Abstract
A low-cost high-speed programmable rasterizer accepting an input set of functionals representing a triangle, clipping planes and a scissoring box, and producing multiple spans per clock cycle as output. A Loader converts the input set from a general form to a special case form accepted by a set of Edge Generators, the restricted input format accepted by the Edge Generators contributing to their efficient hardware implementation.
