Abstract
Embodiments of the present invention sets forth a method and system for reducing memory bandwidth requirements for an anti-aliasing operation. The first virtual coverage information for a pixel involved in an anti-aliasing operation is maintained in memory. If a certain operating condition of the anti-aliasing operation deterministically implies the second virtual coverage information for this pixel, the second virtual coverage information, as opposed to the first virtual coverage information, is used in the anti-aliasing operation. In such situations, since the virtual coverage information is implied, it does not have to be accessed from memory, thereby improving overall system performance.
