All this talk makes me wonder (and I know this
question has been answered
before, but I have forgotten): what equipment did they use to do the
computer graphics in movie Tron?
One company (there were at least three for Tron), MAGI, actually used an IBM
Mainframe programmed with punch cards (I don't know which framebuffer they
used). Not too exciting to watch being done. Remember, CG was and still is
made in non-real-time, only back then it was a little more extreme.
MAGI Synthavision was a real early bird. I remember seeing an article for
it in
Popular Science in the 70's.
