摘要：A system and method for providing antialiasing of a graphical image on adisplay is disclosed. The graphical image is generated from data describing at least oneobject. The display includes a plurality of pixels. The at least one object includes aplurality of fragments. A portion of the plurality of fragments intersects a pixel of theplurality of pixels. Each of the plurality of fragments including an indication of a portionof a corresponding pixel is intersected. The system and method include providing at leastone active region for the pixel. The at least one active region intersects a first portion ofthe pixel. The method and system also include providing at least one new region. A firstportion of the at least one new region indicates where in the pixel the at least one activeregion and the fragment intersect. A second portion of the at least one new regionindicates where in the pixel the at least one active region and the fragment do notintersect. The method and system further include blending a portion of the fragment in asecond portion of the pixel corresponding to the first portion of the at least one newregion.
