The graphics processing pipeline comprising a screen-space pipeline and a tiling unit. The screen-space pipeline includes a z-cull unit configured to perform z-culling operations. The tiling unit is configured to determine that a first set of primitives overlaps a first cache tile. The tiling unit is also configured to transmit the first set of primitives to the screen-space pipeline for processing. The tiling unit is further configured to select between processing the first set of primitives in a full-surface z-cull mode or processing the first set of primitives in a partial-surface z-cull mode. The tiling unit is also configured to cause the z-cull unit to process the first set of primitives in the full-surface z-cull mode or to process the first set of primitives in the partial-surface z-cull mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Higher accuracy Z-culling in a tile-based architecture","description":"A graphics processing pipeline configured for z-cull operations.
