Abstract

The early depth test stages 4, 13 of a graphics processing pipeline 1 are configured to broadcast information 9, 10, 11, 14 about fragments, etc., that pass those early depth tests to other stages 3, 4, 6, 12 in the pipeline. The other stages in the pipeline then use the early depth test pass information to determine if the processing of any fragments that they are currently processing can be stopped.
