Abstract:
An apparatus, comprising:logic configured to convert a primitive into pixel locations in screen space, each pixel location being defined by an x coordinate and a y coordinate in screen space, each primitive having a plurality of vertices, each of said vertices being defined by an x coordinate and a y coordinate, said logic subdividing said screen space into a plurality of regions, each region corresponding to a plurality of pixel locations in screen space, said logic determining whether a particular one of said plurality of regions is entirely outside of said primitive, entirely inside of said primitive, or partially inside of said primitive, wherein when said logic determines that a particular region is entirely inside of said primitive, said logic converts the particular region into pixel locations in screen space, forwards a two-dimensional region of pixel information generated in a hierarchical tiler to a frame buffer, and wherein said logic performs a scan conversion of the two-dimensional region to determine pixel locations in screen space corresponding to a primitive.
