Abstract
A system and method for dynamically adjusting the pixel sampling rate during primitive shading can improve image quality or increase shading performance. Hybrid antialiasing is performed by selecting a number of shaded samples per pixel fragment. A combination of supersample and multisample antialiasing is used where a cluster of sub-pixel samples (multisamples) is processed for each pass through a fragment shader pipeline. The number of shader passes and multisamples in each cluster can be determined dynamically for each primitive based on rendering state.
