Abstract:
In a raster stage of a graphics pipeline, a method for accelerated start tile rasterization. The method includes defining a window for clipping a generated image and receiving a graphics primitive for rasterization in a raster stage of a graphics processor. A binary search related to the window is performed to determine a start tile having at least a partial coverage of the graphics primitive, wherein the start tile comprises a plurality of pixels. Based upon the start tile, the raster stage rasterizes the graphics primitive by generating a plurality of adjacent tiles having at least a partial coverage of the graphics primitive.
