Abstract
Systems for performing rasterization are described. At least one embodiment includes a span generator for performing rasterization. In accordance with such embodiments, the span generator comprises functionals representing a scissoring box, loaders configured to convert the functionals from a general form to a special case form, edge generators configured to read the special case form of the scissoring box, whereby the special case form simplifies calculations by the edge generators. The span generator further comprises sorters configured to compute the intersection of half-planes, wherein edges of the intersection are generated by the edge generators and a span buffer configured to temporarily store spans before tiling.
