Abstract
Described is a method of rendering an image. A transparency of a destination pixel and a transparency of a source pixel are determined at multiple sample positions in each pixel. A new pre-multiplied color is determined for the destination pixel in response to the transparencies of the destination pixel, the transparencies of the source pixel, a color of the source pixel and a pre-multiplied color of the destination pixel. New transparencies of the destination pixel are determined at the samples in the destination pixel in response to the transparencies of the source pixels and the transparencies of the destination pixel. The method of the present invention permits rendering of polygonal two-dimensional images while eliminating overdraw, therefore using less memory bandwidth than conventional methods for rendering typical two-dimensional vector images. Thus the method is suited for mobile computing and other applications with limited memory bandwidth.
