Abstract
A pixel based method for the computation of sub-pixel area-coverage is implemented in an area-coverage hardware module, within a 3D computer graphics rendering engine. Unlike the prior art segment based method which requires an operating aperture of an entire segment, the present invention only requires an operating aperture of one pixel. Therefore, the overall system pixel yield rate is increased.
