Hidden surface removal in graphics processing systems

The early depth test stages 4, 13 of a graphics processing pipeline 1 are configured to broadcast information 9, 10, 11, 14 about fragments whose sampling points 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 p...

Zusammenfassung:The early depth test stages 4, 13 of a graphics processing pipeline 1 are configured to broadcast information 9, 10, 11, 14 about fragments whose sampling points 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 that occupy the same position as the sampling points can be stopped.
