Abstract
This paper presents a way to hold the depth information in Z-buffers, that allows fast incremental computation of Z-buffer depth values. The main idea is to store the inverse depth with each pixel value. The incremental depth computation can then be done with a single addition per pixel in a scanline.Additional Files and Images
