I had the same problem with IDL running on Fedora Core 4 out of the
box. I couldn't get hardware rendering to work in color.
If you are using linux then I would recommend getting the latest 3D
graphics card drivers from the manufacturer rather than using the stock
standard kernel drivers. You will also probably want to turn off
automatic kernel updates, or remember to re-run the graphics driver
install application each time you update your kernel.
If you are using windows then I would recommend getting the latest 3D
graphics card drivers from the manufacturer rather than using the
Windows installation CD.
I still find object graphics to be a bit quirky on my box. Very
occasionally, my 3D graphics will spit the dummy a refuse to render.
Sometimes have to restart my X session to get 3D graphics in IDL. I
haven't had the problem for a few months now and it was not
reproducible enough to warrant a bug report. It was probably solved in
a driver update or something.
