A few articles back a person inquired about a paper on an algorithm analysis by Profs. Wyvill and Cleary. I am trying to track that paper down but the reason for sending you this letter is to request some info. on the mesh machine for ray- tracing developed at your univ. If you can refer me to a recent paper on this machine it will be great. At Duke we are developing what has come to be known as the Raycasting machine which computes intersection of an array of parallel rays with primitives and then uses constructive solid geometry to compute the shape, volume and other parameters of an arbitrary object. Thus I would be very much interested in any work in this area. > >If anyone else is interested in references on parallel raytracing >(the mesh machine articles, Pearces Masters thesis, or others >such as Dippe in Siggraph 86 etc) you can send me mail and I can send >a list or copies of some of t > Any other info. in this area would be very much appreciated.
