A parallel rendering approach to the adaptive supersampling method

Abstract

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 methods have been proposed to address this problem. Most of them suffer from requiring a large memory space, demanding for high computational power, or having some other limitations. Recently, we presented a simple anti-aliasing method based on the supersampling method. Instead of supersampling every pixel, we supersample edge pixels only. In this paper, we discuss various approaches for parallelizing the method and their effects on memory usage and performance.
