✦ Synopsis

It is sometimes desirable to highlight intersection curves in order to make the shapes of penetrating surfaces more visible. Highlighting the intersection is especially helpful when the surfaces become transparent, because transparency makes the intersections less evident. This paper discusses a technique for locating intersections in screen space using only the information locally available to a pixel. The technique is designed to exploit parallelism at the pixel level and has been implemented on the Pixel-Planes 5 graphics supercomputer.
