afaik (being somewhat involved in the project), this is not really peter's problem. 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. fgmasdr IOhannes PS: note the slight change in wording in my email, from "peter" in the beginning to "we" in the end. it's somewhat unintentional :-)
