updating object graphics? [message #29306] Mon, 11 February 2002 07:59

I'm experimenting with object graphics by attempting to modify
the alphablending example in the IDL 5.5 what's new docs (p 328
in the pdf version). I thought that a resonable first thing to
try would be to write something that let me change the
transparency and update the image. As in, display base image and
overlay with default transparency and then loop while I read a
new transparency, update the alpha blending and overlay image.
I'm stumped at trying to update the graphics display though.

Is there a way to modify a IDLgrImage and update the display? As
far as I can tell, there is no way to update the image in
IDLgrImage or to remove or replace an object in a IDLgrModel
either. Is there a place where this sort of thing is written out
in tutorial/users' guide form?

Mike
