1. In a raster stage of a graphics pipeline, a method for rasterizing non-rectangular tile groups comprising: receiving a graphics primitive for rasterization in a raster stage of a graphics processor; rasterizing the graphics primitive at a first level by generating a non-rectangular footprint comprising a set of pixels related to the graphics primitive; and rasterizing the graphics primitive at a second level by accessing the set of pixels and determining covered pixels out of the set of pixels; and outputting the covered pixels for rendering operations in a subsequent stage of the graphics processor.
