I'm wondering if anyone would like to share their experience with
running IDL5 on systems equipped with OpenGL hardware. In particular for
PC and Mac systems,
(1) What graphics hardware you have,
(2) What driver(s) you are using,
(3) What kind of IDL performance benefits you have noticed.
The reason I ask is that yesterday I was able to play with a fast SGI
Octane workstation running the wonderful Vis5D package (check it out at
(see http://www.ssec.wisc.edu/~billh/vis5d.html) and I'd like to
eventually realize the same kind of 3D performance on a PC running IDL.
Cheers,
Liam.

We found it out!
Thanks to Karl Schultz, who pointed us to the graphics card.
The resolution we were using was too high for the graphics
card to support OpenGL. Reducing the resolution no memory is
lost. So, we do not know were the problem is. But we know how
to avoid it.
Thanks.
