I don't know what this means. SURFACE/SHADE_SURF is also nice for doing surfaces - it also
has the clear advantage that when I hit the enter key, I get immediate feedback, i.e. my
data displayed onscreen. Maybe the OG stuff on my computer is slow because I like to look
at large data sets. But, then, why is the DG output so fast?

I just downloaded it and gave it a shot - very nice. The one thing I want to do with
surfaces, rotate them with the mouse, was actually easy to do and relatively speedy.
Thanks for the tip - the code has been added to my idl/user_contrib directory. I tried
doing the same with iSurface and, well, frankly, the user interface totally bamboozles me.
It's difficult to play with iSurface since because any action on my part takes so long to
show up onscreen, it gets hard to connect action and reaction. The end result is that
there's no carrot to entice me to investigate the capabilities of these tools any further.
I tried surfacing a DIST(1000) array with DG SURFACE (fast), iSurface (slooow), and
fsc_surface (slower than DG surface, but faster than iSurface). I'm still waiting for the
OG surfacing of a DIST(5000) array to display (3minutes after the DG equivalent finished
its ~30s march across the window.)

Nope - it's brand spanking new. :o) It took 3 years to get a replacement tho'. :o(
Maybe it's my level of crotchety-ness increasing with age, but if it takes longer than 5
minutes for me to just *look* at my data, I'm not interested. What with everything else
going on in the world nowadays, the last thing I need is yet another thing to raise the
blood pressure. :o)
