Hi, thanks for yesterday's replies. We used the clone mode passive stereo because our demos are not only based on real time graphics but also we have some stereo movies, so that mode is convenient for every application we want run in passive stereo.
One thing you might want to consider is use the OSG to do stereo movie playback, this is something I done quite a bit of under Linux and OSX.
We have six projectors in two rows with Infitec tecnology, they can be fed in two ways: one signal for every projector (we still have the duets for splitting the active stereo to passive, from the previous installation), this is the case of the Prism machine; the other way is one signal for one row of three projectors, since they are digital they can take one third of the pixels coming from the signal, so for istance we feed them with one workstation with an Nvidia Quadro FX 4500 configured at 3496x1050 (which is 1400x1050 by three, minus the edge blending), with passive stereo, that's to say both two signals taken from the Quadro. So, if SLI works properly with one signal only, the only way is to use active stereo, split it with the Matrox TripleHead2Go, and feed the three signals to the duets and obtain 6 signals. But there is a problem: the Matrox TripleHead2Go supports only 1280x1024 by three, while the native resolution of the projectors is 1400x1050.... ouch!
I don't think the TripleHead2Go will support 1400x1050, but you could contact Matrix to see. The other option open is using three DualHead2Go.
Unless things will be different with Quadros vs GeForce, maybe passive stereo will be supported with the new Quadros 4500 X2? Maybe they'll solve the threading issue? Or we have to do another crusade against Nvidia this time? :)
I'd rather do a crusade "with" rather than against :) First things first is to establish where the threading issue lies, then working with NVidia/ATI to sort it on each system.
