Rolling Stereo in a CAVE (Best I can describe it)

[shivanangel]

Hello,

I have a 4 wall CAVE system that uses Vizard, the PPT tracking system and an inertia cube to give me my rotation. One issue I have been running into time and time again is what I have dubbed 'rolling stereo' on one of the screens.

From time to time I will walk into the CAVE and as I look around I will notice that one screen seems to not be properly in stereo. That is, all the other screens appear in stereo, but when I look at 'lets say the far right' it would not be in stereo but instead slowly 'roll' in and out.

This rolling is completely invisible unless you put on the stereoscopic shutter glasses. When you put them on, the stereo seems to go in and out over about 15 -30 seconds and will continue to roll in and out from being separate and united.

I was wondering if you had ever come across this issue before.

We are using NVIDIA Quadro 5600s on each client (one client for each screen) and a master node using a 4600 where we control everything.

If I restart the computers this is usually how I get rid of the problem but today as I was working I was running into it again and again across all sorts of demonstrations.

Is there an official name for this phenomenon? Have you ever heard of it? It is causing my eyes to go cross-eyed!

Thanks,
George
