Spanning Monitors with Quartz Builder

Hi I am working on a composition that needs to span a pair of monitors is there away to do this with a QC wrapped in a Quartz Builder application. So far I can only get the composition to go fullscreen on one monitor. Cheers Steve

Re: Spanning Monitors with Quartz Builder

Unfortunately, this isn't possible with 1.0 (without knowing both screen sizes in advance). It's slightly possible in the upcoming 1.1 release (it provides you with screen sizes, among many other new features).

I say slightly, because there can be other caveats -- if both screens are on the same GPU, it's likely not a problem, but if the screens are too wide, it can fail (for example, a 1440x900 + 1280x800 are too wide for my GMA950, so full dual-screen will fail). I don't think this is a problem for NVidia or ATI cards though. Also, if both screens are on different GPUs, I don't think it'll work correctly (multi-GPU contexts aren't particularly high-performance, if they're even possible).

I think the right way to deal with this is to have a full screen window on each screen, with each set to draw a subset of the full context. I'll have to look at Quartz Visualizer to be sure, but I think it did something like that? That avoids size and multi-GPU issues all together.

As smokris pointed out, two comps (each full screen) either hosted on same mac or separate can communicate using OSC or other comms plugin.

Being able to send cropped parts of the image with the spooky patches would be a nice feature! :)
