ABSTRACT:
A value for expressing the fraction of the area occupied by a polygon within a pixel and a value for expressing the degree of transparency of the pixel are multiplied together for each pixel. The multiplied product is reset as the degree of transparency for each pixel, according to which a color preset for each pixel composing the polygon is mixed with the colors of other pixels rendered on a two-dimensional coordinate which is substantially the same as that for the pixels composing the polygon. This allows semi-transparent polygons to be processed by anti-aliasing without being changed into opaque polygons.
