Single-pass full-screen hardware accelerated antialiasing

This paper describes a modified A-buffer algorithm and its hardware architecture for single-pass full-screen antialiasing. For storage and management of fragments, a dynamic memory management scheme, which can be efficiently implemented by hardware is introduced. In the fragment resolving stage, a subpixel color-blending scheme that resolves subpixels simultaneously is used to correctly blend transparencies and resolve intersections of polygons in a pixel. A rasterization processor architecture, which can process multiple pixels simultaneously, is also presented. CR
