Graphics system having a super-sampled sample buffer with generation of output pixels using selective adjustment of filtering for implementation of display effects

Abstract From the Canadian patent

A computer graphics system that utilizes a super-sampled sample buffer and a programmable sample-to-pixel calculation unit for refreshing the display wherein the graphics system may adjust filtering to reduce artifacts or implement display effects. In one embodiment the graphics system may have a , graphics processor a super-sampled sample buffer, and a sample-to-pixel calculation unit. The graphics processor renders a plurality of samples and stores them into a sample buffer. The sample-to-pixel calculation unit reads the samples from the super-sampled sample buffer and filters or convolves the samples into respective output pixels which are then provided to refresh the display. The …
