Abstract
In a raster stage of a graphics processor, a method for using low precision evaluation and high precision evaluation for conservative triage of polygon status. The method includes receiving a graphics primitive for rasterization in a raster stage of a graphics processor and rasterizing the graphics primitive to generate a plurality of tiles of pixels related to the graphics primitive. The tiles are rasterized at a first level precision to generate a plurality of sub-tiles related to the graphics primitive, wherein the sub-tiles are evaluated against the graphics primitive at each of their respective corners. Each of the sub-tiles not related to the graphics primitive are discarded. The sub-tiles related to the graphics primitive are rasterized at a second level precision.
