I don't really know the answer to this, because
I've never tried to write an OpenGL-type of
program. But I do spend quite a bit of time with
my nose in an OpenGL-oriented graphics book trying
to figure out what the heck is going on in object
graphics.

My impression is that as low-level as IDL's object
graphics API is, it is still at a higher level than
OpenGL. At least I'm always thinking to myself, "Oh,
I see how IDL does that!", and I'm always glad I don't
have to do it myself.

Cheers,

David
