From our database, we have a 4800 by 6000 point grid of colors and elevation. Currently this is rendedered in perspective on our 835 Turbo SRX using the triangular_strip routine. (We average down the grid to 1000 x 1200 so it will fit in memory). This means each vertex has to be feed to starbase twice. It takes nearly 1 minute per image. I'll be doing this a lot - we're making a movie. What I'd really like it a routine which would take a rectangular mesh in which I only need to specify the color and elevation at each point. Anyone out there have a suggestion for doing this, or anything else that would speed the process up? the time command reports 100% CPU utilization, but I can't believe this isn't graphics box limited. Is there any support for user written microcode for the graphics accelerators? Dan Stodolsky Visualization Engr. Design Research Center danner@edrc
