afaik (being somewhat involved in the project), this is not really
he is already rendering into a big framebuffer.
the question is rather, whether someone has a ready-made solution for
displaying the image on multiple overlapping projectors, that they want
to share. (if it is simple enough, it could go into the Gem/examples/...
think of all the fame!!!!)
the last solution we used for that (on 8 overlapping projectors), had a
proprietary license and could only be setup by the developers... so we
are looking for something more simple and open.
PS: note the slight change in wording in my email, from "peter" in the
beginning to "we" in the end. it's somewhat unintentional :-)
