  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.",
