ABSTRACT:
An image generation system having a processing element array comprised of a plurality of processing elements interconnected so that processing elements may communicate with other processing elements in the processing element array. A linear expression evaluator provides coefficients of linear expressions which define object primitives to the processing element array and a processing element array controller provides instruction and control data. A central control unit controls the flow of data to and from the processing element array and controls the presentation of linear expression coefficients to the linear expression evaluator. Methods, apparatus and program products include assigning home pixel addresses corresponding to pixels of the screen regions to the plurality of processing elements. A database of geometric primitives is traversed and each primitive is assigned processing elements. The processing elements generate and store linear coefficients Geometric primitives which touch each screen region are provided to the processing elements which determine whether the home pixels of the processing element are within the geometric primitive and calculate the subpixel coverage of the home pixels. Contributions are scattered throughout the processing elements for processing and returned to the home pixels to determine a final pixel value.
