ABSTRACT:
In a raster unit of a graphics processor, a method for bounding region accumulation for graphics rendering. The method includes receiving a plurality of graphics primitives for rasterization in a raster stage of a graphics processor and rasterizing the graphics primitives to generate a plurality pixels related to the graphics primitives and a plurality of respective bounding regions related to the graphics primitives. Upon receiving an accumulation start command, the bounding regions are accumulated in an accumulation register. The accumulation continues until an accumulation stop command is received. The operation results in an accumulated bounding region. Access to the accumulated bounding region is enabled to facilitate a subsequent graphics rendering operation.
