Abstract
Methods and systems for processing fragment groups are described. Fragment groups that include z-only pixels are accessed. A z-only pixel has associated therewith two or more z-values instead of a single z-value. Fragment groups that are not covered by a geometric primitive are discarded, while fragment groups that are covered by a geometric primitive are forwarded to a shader pipeline.
