Abstract
A graphics system and method for storing pixel values into or reading pixel values from a sample buffer, wherein the sample buffer is configured to store a plurality of samples for each of a plurality of pixels. The graphics system comprises a sample buffer, a programmable register, and a graphics processor. The programmable register stores a value indicating a method for pixel to sample conversion, and is preferably software programmable (e.g., user programmable). The graphics processor accesses the memory to determine a method for pixel to sample conversion and stores the pixel values in the sample buffer according to the determined method. A first method for pixel to sample conversion may specify a pixel write to all of the pixel's supporting samples. A second method for pixel to sample conversion may specify a pixel write to a selected one of the pixel's supporting samples.
