would be much appreciated :-)I can only offer my $0.02 worth:
I think this area deserves a careful examination. (Thanks for volunteering
Ben.) I suspect you will find that performance is important, but that the
ranking of the different methods will vary widely depending on OS, graphics
hardware, IDL settings and day of the week.
My urge is to abandon the object graphics in this case and use direct
graphics. I have bumped into this question because I am converting
a direct graphics routine that I wrote a long time ago (it is very fast)
to object graphics. Now it is mostly complete, but the interactive
business is getting to be a bit of an event-processing-rendering bottle
neck.
My only redeeming quality is that I tend to perceive failure as good information. :-)
David, Have you ever read the wonderful Emily Dickinson poem about
the sweetness of success to those who rarely experience it? If not,
I'll dig it out and send it to you.
Thanks again,
Ben
