Abstract
A method and apparatus for processing a primitive for potential display on a display device (having a plurality of pixels) determines if the primitive intersects at least a predetermined number of pixel fragments on the display device. The predetermined number is no less than one. The method and apparatus then cull the primitive as a function of whether the primitive intersects at least the predetermined number of pixel fragments. If it is culled, the primitive is not raster processed (i.e., not subjected to raster processing, whether or not complete).
