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 a

plurality 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 that is intersected. The system and method include providing atleast one active region for the pixel. The at least one active region intersects a firstportion of the pixel. The method and system also include providing at least one newregion. A first portion of the at least one new region indicates where in the pixel the atleast one active region and the fragment intersect. A second portion of the at least onenew region indicates where in the pixel the at least one active region and the fragment donot intersect. The method and system further include blending a portion of the fragmentin a second portion of the pixel corresponding to the first portion of the at least one newregion.
