Abstract
A system, method, and computer program product are provided for generating anti-aliased images. The method includes the steps of assigning one or more samples to a plurality of clusters, each cluster in the plurality of clusters corresponding to an aggregate stored in an aggregate geometry buffer, where each of the one or more samples is covered by a visible fragment and rasterizing three-dimensional geometry to generate material parameters for each sample of the one or more samples. For each cluster in the plurality of clusters, the material parameters for each sample assigned to the cluster are combined to produce the aggregate. The combined material parameters for each cluster are stored in an aggregate geometry buffer. An anti-aliased image may then be generated by shading the combined material parameters.
