GRAPHIC PROCESSING UNIT AND TILE-BASED RENDERING METHOD

摘要

A graphics processing unit (GPU) is provided. The GPU includes a tiling unit and a rasterizer. The tiling unit is configured to determines primitives touching a corresponding tile in tiles in an image frame, to determine at least one representative primitive of the primitives using a depth value of each of the primitives, and to generate visible primitives of the primitives for the corresponding tile using a depth value of the at least one representative primitive. The rasterizer is configured to rasterize the at least one representative and the visible primitives.

1. A graphics processing unit comprising:
a tiling unit configured to identify a plurality of primitives touching a corresponding tile of a plurality of tiles in an image frame, to determine at least one representative primitive of the plurality of primitives using a depth value of each of the plurality of primitives, and to determine visible primitives of the plurality of primitives for the corresponding tile using a depth value of the at least one representative primitive; and a rasterizer configured to rasterize the at least one representative primitive and the visible primitives for the corresponding tile, wherein the at least one representative primitive is rasterized prior to the visible primitives, and the visible primitives are rasterized according to a rendering order.
