Abstract
Graphics systems manipulate data embodying one or more objects for display. The objects are typically represented by a plurality of faces. In order to rasterize an object for display utilizing a plurality of rasterization engines, the present invention partitions at least one face of the object into a plurality of sub-faces according to a first cost function representing cost of rasterizing the face, and assigns the sub-faces to the plurality of rasterization engines for rasterization. The rasterization engines rasterize the sub-faces to generate pixel data representing the object for display. The partitioning of the face of the object into the plurality of sub-faces may be based upon a second cost function representing cost of rasterizing at least one of the sub-faces. Preferably, each of the sub-faces has equal rasterization cost and each of the sub-faces do not overlap one another.
