I just use a little X-library that I have for doing very simple graphics
under X -- it draws and erases dots, lines, and boxes. That's enough for
simple scientific visualization. I'll send you a copy, and if anyone
else is interested... (For instance, I got a "real-time" viewer for
a simple NlogN code working in less than an hour.)

The engineering lessons and experience from building the spacecraft and instruments will remain on Earth to benefit future missions if we choose to undertake them." -- Steve Collins || Wayne Hayes wayne@csri.utoronto.ca
