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.

Hello! Well, the softedge/overlap is quite useful in installations, since projectors sometimes have the bad habit of moving slightly, even when installed as proper as possible. If i do it Hard edged, meaning that the borders of the single images are exactly edge to edge this would lead to a gap between the pictures.the triplehead is just the solution to make a really wide image with 3beamers, but doesn´t give me a solution for that particular problem, at least as far as i know. regards, peter

Why do you need overlap if you are going to use a triplehead2Go?

Hello List!
I have a question regarding the work with multiple projectors: I am looking for solution within Pd/Gem to process the output in the GEMwindow in a way, that i can work with a TripleHead2Go fullscreen and to be able to set up the 3 Projectors with an overlap.
I know that there are some Hardware solutions, but far away of being affordable.
regards, Peter
