In one embodiment, the present invention is implemented as a GPU configured for traversing pixels of an area. The GPU includes a set-up unit for generating polygon descriptions and a rasterizer unit coupled to the set-up unit for rasterizing the polygon descriptions. The rasterizer unit is configured to traverse a plurality of pixels of an image using a first boustrophedonic pattern along a predominant axis, and during the traversal using the first boustrophedonic pattern, traverse a plurality of pixels of the image using a second boustrophedonic pattern, wherein the second boustrophedonic pattern is nested within the first boustrophedonic pattern.
