Murray <> Administrivia to: graphics-request@scri1.scri.fsu.edu Try muxing the outputs from 1000 framebuffers into a single analog stream. I would rather pass on this approach. The PixelFlow box captures the output from a composition network rated at 4 Gbytes/s into a single frambeubffer. I don't believe this approach is truly scalable either, since its still an example of the N to 1 mux problem. So it is, in my opinion, contention limited (the laws of physics won't cooperate and provide infinite digital bus or network bandwidth). I advocate a tessellated display approach myself, where each tessellation element owns a processor, framebuffer, and display. The trick is to coordinate the system temporally. The scalable concurrent visualization system trades contention for asynchronous execution. --rick -- Richard Marlon Stein, Internet: rms@well.sf.ca.us To those who know what is not known; The Chronicles of Microwave Jim! -- Moderated by SCRI Vis <> Submissions to: graphics@scri1.scri.fsu.edu Guy, John R.
