An Adaptive Supersampling Method

Original z-buffer method is a very efficient method for image generation. The limitation is that it introduces aliases into the output image. Although many different kinds of methods have been published to address this problem, most of them suffer from requiring a large memory space, demanding for high computational power, or having some other limitations. In this paper, we propose a simple anti-aliased method based on the supersampling method. However, instead of supersampling every pixel, we supersample edge pixels only. This method has the advantages of requiring less memory and less processing time than the traditional supersampling method. It is also less problematic than some other rendering methods in handling intersecting surfaces.
