ABSTRACT:
Graphic processor compares z-buffer values of 3D objects to detect and mark interpenetrating pixels. Tag buffer stores marked values for antialiasing effectively by over-sampling, area-based, blending, alpha edge or other pixel-processing scheme. Performance is improved by selectively antialiasing at edges and/or interpenetrations. Cost is reduced by leveraging z-buffer storage therefor. Super-sampling antialiasing reduces sampling of select interpenetration elements, thereby avoiding processing entire image.
