Bonjour Luc, I work with nVidia Quadro FX 5600 and nuvision emitters and 60GX LCD shutter glasses on a daily basis. OSG will work out of the box in QUAD_BUFFER mode. Excellent, that's the news I wanted to hear! I knew about the environment variables, I was just wondering if it was a default quad-buffer setup or if I needed to do any tweaks. Thanks a lot.

Hi Bob, Thanks for the input. OSG works very well with our setup. The only piece that is currently missing is configs for the various physical geometric forms our display surfaces can take. I think this is all very close, however. You mean about having to use environment variables instead of config files? That's not really an issue for us, it'll just be a small demo app for now and we have our own config file support in our framework so we'll likely just add some settings there to support stereo. Good to know that getting the stereo running with OSG is relatively painless. I don't know of any reason why this wouldn't work. While anaglyph introduces cruft into the colorspace, it serves as a quick way to preview what you've got. I use this methof frequently when work on my home machine (FX8600).

I suppose env variables would work for simple cases, but I need to be able to put my displays into a non planar config - orthogonal surfaces. Hmmm, that would be interesting for us too, but in a different project... We have a simulator which uses 4 screens (left, right, front, top) all oriented toward the user, but not necessarily at 90 degree angles or centered, and it also has a head tracker. This setup requires asymmetric view frustums which are specified using physical measurements (viewer position and screen corners), and the current code to do that is kind of ugly and painful to look at, so if something like what you're talking about could be used for that, it would be great. I hope you'll consider contributing what you come up with for inclusion into OSG. Interesting stuff.

Re: [osg-users] Active stereo support in OSG?
Hi Bob and J-S, The current stereo support assumes a powerwall setup, so while easy to use isn't that generic. For generic support one needs to manage things at a higher level - up in osgViewer as I've done with the spherical display support. My plan is to move stereo support entirely within osgViewer and with it provide the viewer configuration support required. Robert.

Re: [osg-users] Active stereo support in OSG?
This is something I would really like to see in OSG. An easy way to do stereo asymmetric displays. Particularly for a head-tracked display. I have never done it, but I have spent some time digging through source code, doxygen files, and the mailing list and I know all the blocks are there. OSG easily supports stereo, has a way to specify skewed projection matrices, and supports camera callbacks for continuous head-tracking, but nothing puts it all together. It would be nice if there was an interface to initially specify the location of the display(s), then at each time-step pass it the 6DOF location of the eye. The code would automatically compute and update the cameras with the proper projections. Just wishing out loud... :) PaulB Jean-Sébastien Guay wrote: Hi Bob, My goal here is to create .cfg files that describe orientation of the display surfaces.

Unfortunatly, I cannot provide for development of the needed code currently.

Sounds very similar to our Mechdyne Flying Flex. We tend to use it in powerwall mode when dealing with the larger groups, but have occasion to close it up into a cave-like configuration as you've described above. We are also quite fond of a 'gullwing' configuration with the left and right walls pulled off of planar by about 2'. This makes for a nice pseudo-curved screen config.

One problem we have is that the hardware is off-site (*far* off-site), and it's unlikely we'll have access to it for testing. We just have regular GeForce 8800 cards and regular monitors here. Should I expect it to just work(tm) ? Is there a way I can do some useful testing here? Perhaps using anaglyphic stereo with red/cyan glasses, (we have those :-) - will that be representative of the quad-buffer stereo support?
