splitting an OpenGL screen

Also if anyone has any awesome links to performance optimization techniques so I can go bigger than 360x240, I'd appreciate it!

Check this topic: https://cycling74.com/forums/one-jit-window-across-two-displays/

Your second question - performance - optimisation is rather general and it is difficult to give advice without knowing what exactly you want to do. But typically - if we are talking about Jitter - your GPU is your friends, so try to move as many calculations as possible onto graphics card (use slab, textures, gen, shaders).

looked at that link, and this one:

Still beating my head against a wall. The example patches don't work. Only one screen is showing anything. My comp is better than the specs they are listing. Using Max 6 in OSX 10.9.5

Not near the triplehead at the moment. Perhaps I can run all 4 from one computer, using the main screen as the 4th. That makes me nervous because I can't do anything on the computer while things are running without the audience seeing it.

I'll keep plugging on.

Dear SUPERSARA

Try describe your problem a bit more detailed:

Are you checked triple head already and it works (you see desktop on all outputs), but you can't display image from Max, or you can't split your image inside Max into 4 independent windows?

Anyway,

try this:

This solution works fine on my computer (actually, this is typical way I'm solving this kind of problems and this "system" works fine on every computer - mac or pc - I ever tested). Good luck ;-)

Yaniki's method seems perfectly valid. You can take any of the 4 render windows and replace that by a network output (are you sure you want to do that? It's likely much more performant to have the computer that renders it also output it to the screen/projector).

In my setup I have 1 monitor display (that the audience doesn't see) and 4 projectors. On the monitor display, depending on the project's needs, I either have a window with the full output scaled down to fit on the display, or I double 1 of the 4 projector outputs on it.

Unless you're doing very complex rendering, have a slow CPU/GPU or you're very inefficient at patching you should be able to get much higher resolution than 4 x 360x240. GPU/OpenGL is your friend.

Btw, I prefer to have one wide render window spanning all 4 projector outputs instead of a separate window for each. That also works.

@DTR: of course! It's a simplest and most stable solution - but may become a bit problematic if you have beamers with different resolutions.

Btw, in your screenshot you can see that the adjacent windows cast a shadow on each other, at the borders, not by Max but by the OSX. Are those shadows there when connected to projectors?
