Abstract
A system and method for merging received pixel fragments with an existing fragment compares a depth range for the received fragment with a depth range for the existing fragment. If there is a range overlap, the new fragment is merged with the existing fragment for which there is overlap. If there is no range overlap, the new fragment is discarded. The merge operation can be performed for fragments received for a single surface, such as the nearest surface. Alternatively, the merge operation can be performed for fragments received for a plurality of surfaces.
