Patent ID: 7961185

Claim:
A graphics processing method, comprising: defining a plurality of rows of tiles in a graphics display field comprising a plurality of rows of pixels, each tile including pixels from at least two rows of pixels; setting occlusion flags for respective tiles of a row of tiles for a graphics primitive based on whether respective representative depth values for the tiles of the row of tiles meet an occlusion criterion; processing pixels in rows of pixels corresponding to the row of tiles for the graphics primitive in a row-by-row manner responsive to the occlusion flags, wherein the step of processing pixels includes: processing a portion of the pixels in a first tile of the row of tiles responsive to the occlusion flags; processing pixels in a second tile of the row of tiles responsive to the occlusion flags after processing the portion of pixels in the first tile; and returning to the first tile to process additional pixels in the first tile responsive to the occlusion flags after processing the pixels in the second tile; and utilizing results of the graphics processing to display enhanced graphics on an electronic display.
