Hi Bob,
We have more or less this exact setup, 2 x Christie Mirage HD3's,
Quadro 5600 and Nuvision 60GX shutter glasses on a 160 degree curved
screen. Once the correct parameters are declared we have has no
problems running in Quad buffer stereo with OSG. The only issue we have
encountered has been with occasional swapping of left and right that we
have isolated to the less than stellar drivers Nvidia have been
releasing of late.
Nifty display setup you have. Thanks for the hint on the left-right field
swap issue. I've seen this as well, although it's only ever occured on the
2nd GPU on the fx4500x2. I'll take you hint about the drivers and dig a
bit.

Objet : [osg-users] Active stereo support in OSG?
Hi everyone,
Hi Jean-Sebastian
I'd like to ask if anyone has experience using active stereo
with OSG.
To be more precise, the hardware we're looking to use is
Mirage HD3K projector
nVidia Quadro FX 5600 video card
nuvision emitters and 60GX LCD shutter glasses
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.
The only thing you'll have to do is to declare some parameters to adjust stereo
with the geometry of your projector :
See :
http://www.openscenegraph.org/projects/osg/wiki/Support/UserGuides/StereoSettings
OSG_STEREO ON Turn stereo on
OSG_STEREO_MODE QUAD_BUFFER Use quad buffered stereo when in stereo.
OSG_SCREEN_DISTANCE 0.50 Set the distance the viewer is from screen in
metres (default shown)
OSG_SCREEN_HEIGHT 0.26 Set the height of image on the screen in metres
(default shown)
OSG_SCREEN_WIDTH 0.325 Set the width of image on the screen in
metres (default shown)
OSG_EYE_SEPARATION 0.06 Set the eye separation - interoccular distance
(default shown.)
And that should be ok for the OSG side.
On the hardware side, you'll have to connect cables :D and check the stereo
enable box in the nvidia settings panel.
You should have the same result than with anaglyphic stereo (a better result in
fact).
Luc
Now, I think this setup requires (and supports) quad-buffer
stereo. And I think I saw that OSG supports that
out-of-the-box. Does it work well?
Any issues setting it up? Any gotchas on the OSG side?
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?
Thanks in advance,
J-S
