US Patent 7369138 Full-scene anti-aliasing method and system

A method and system for performing full-scene anti-aliasing for an image through a technique of rotating and unrotating rasterization of a scene and rendering a resulting image. A scene is rasterized at a first angle relative to a first coordinate system to generate a plurality of pixels, which are then applied to a polygon surface that is rendered at a second angle equal to the inverse of the first angle. Thus, the resulting image is re-oriented with respect to the first coordinate system.
