The alpha channel comprises either a sub-pixel mask which indicates the amount and sub-pixel regions of coverage or a single value indicative of the percentage of coverage of a pixel. The pixel between the edge pixels of the polygon are turned (310), thereby filling the polygon. The pixels of the polygon are then composited with the background pixels. A depth (Z) value of each pixel determines the equations used (320, 330, 350, 370) to composite polygon to the background, updating the color of the pixel, the z buffer value of the background pixel and the sub-pixel mask (340, 360, 380, 390). Through this single pass method high quality anti-aliases polygons may be rendered without performing the time consuming process of sorting the polygons in depth order prior to compositing.,下面是METHOD AND APPARATUS FOR RENDERING ANTI-ALIASED POLYGONS专利的具体信息内容。
