Nvidia 3D Vision
Samuel Gateau from Nvidia
I have his slides on my computer. He made some great illustrations of how stereo works.
They discussed the 'how to' of applying stereo to games.
Nvidia 3D vision discover glasses
Nvidia 3D vision – active shutter glasses synchronized with the display

How it works –
3D game data is sent to stereoscopic driver
The driver takes the 3D and renders each scene twice
display 120Hz is 60Hz per eye

NVAPi stereoscopic module – provided to developers

the look of depth
controlling stereo parameters
parallax budget
how much parallax variation is used in the frame
at 100*screendepth, parallax is 99% of the separation
between 10 to 100 * screendepth praallax vary of only 9%
at screendepth / 3, parallax is 2* separation, out of the screen
parallax is very large (> 2*Separation) and can cause eye strains – don't go over this distance

They had trouble with subtitling – For the next game their solution was to cut the subtitles.
There will be no 3D support on game consoles?
