Hi, interesting thread. Recently my team started experimentation with Stereo and the new Nvidia glasses. We use of course OSG, and we were wonder how we could use the glasses with OpenGL.
Here are our impressions and results (for those of you who are interested): We have a Quadro FX 370 (i think this is the worst one for the Quadro series) and it has Stereo support (activation required via control panel), i.e. OSG can use QUAD_BUFFER, but it does not have the stereo plug, so we use this vga stereo adapter to generate the sync signal ( http://www.int03.co.uk/crema/hardware/stereo/) (use pin 10 and 14 of vga DB15, that is vertical sync). Recently i discovered that Lightspeed (DepthQ's vendor) sells an vga stereo adapter. I suppose there must be other vendors thats provides those, aren't they? Of course (thanks Nvidia), the 3d vision driver does not like Quadro drivers, so it does not install. Therefore we use another pc with a Geforce card, where we install the driver and the ir emitter. In this pc we configure the driver to use a HDTV DLP or a generic crt, otherwise the ir emitter neglects to use the minijack sync in signal. Also, for the ir emitter to work, it must have a fullscreen directx application running (we use the test from the control panel because we run on windows), otherwise it will be in standby mode. After some experimentation we achieved it and we were able to "see" in stereo with OSG in the other pc with the quadro. Our impressions: Though the glasses are "VESA compatible", the ir emitter doesn't work if it isn't connected to the pc via USB AND a DirectX application is running fullscreen. The ir emitter does not use the sync in signal if it is connected to a "3d ready" display (either samsung 120Hz lcd and DepthQ projector). It seems to prioritize the usb signal in these cases. The glasses doesn't work for us at 75Hz display vertical sync. We used 60Hz and all went ok, but with a 75Hz refresh rate we experimented sync problems. Rivatuner and 3d vision drivers aren't compatible with each other. You can't install them both (again, windows platform). Only one question without answer: Will the Nvidia shutter glasses work with a standalone DLP TV with 3d support? Where will the ir emitter be connected, via sync in signal to the tv or via usb cable to a pc? Will never know, the glasses are a bit of disappoinment. So, although we were able to make it work, it seems that there are only two options: Either Nvidia adds supports for quad buffer in their drivers (as stated here http://www.nvidia.com/object/quadro_stereo_technology.html) or we better stand with the "professional" shutter glasses and forgets about the Nvidia "only for games" ones. Ah, maybe someone out there with a Quadro FX with the stereo plug and the nvidia shutter glasses can reply me: Does the glasses work with it? Best Regards, Himar.
