hello,
i don't have a ready made solution, but once you have a FB, nothing should be very complex.
unless i miss the complex part of the problem.
if i've got 5 min later tonight, i'll try to make a soft_edge shader that can deal with everything...

hello,
one solution is to render your scene in a big framebuffer. (if you use 3 screen of 1024x768, and a 100 pixel overlap, then you need a 3x1024-2x100 pixel wide framebuffer)
then render this frambuffer as a texture on 3 rectangle, using pix_coordinate in order to keep only the desire part of the image. the black fade can be made with shader or texture as you prefer.
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.

PS: note the slight change in wording in my email, from "peter" in the beginning to "we" in the end. it's somewhat unintentional :-)
