[osg-users] Active stereo support in OSG?

[Jon Newell]

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. 

cheers

Jon
