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

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

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 :-)
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...

it's not a complicated problem. the most complicated part is the calibration to the actual projection space.

Yep, i did something similar with my last game PdTron ;) But i have no time today to work on this new problem... ++

Hello,
Here is something generic. it should work, but it's not fully tested.
is that what you are looking for? if so, is there missing features?

Wow, this looks definitely more then promising. I`ll look deeper into it, and have you updatet with the project. THANKS A LOT!
