I am sort of an object graphics newbie. I think it works really well,
and I would recommend it (in a newbieish sort of way). One thing that
I've noticed is that if I'm rendering a very large view, the IDL
process's memory size can grow to be enormous (upwards of 2-3 GB
sometimes).

On the machine I'm rendering on, this wouldn't be a problem except that
IDL does not seem to relinquish that memory after the view has been
rendered and the objects destroyed. Its only after the IDL process quits
that the memory is recovered by the OS. This seems contrary to the way
IDL manages its heap.

So I was thinking that this memory is overflow from the videocard's ram
and is allocated by the operating system independent of IDL, and so it
is not under IDL's direct control. Does that seem reasonable?

Thanks,
Bill
