Hi Jan,
Have you seen most recent NVAPI release specs Christian mentioned about ?
There is definitely more interesting stuff for Direct3D game developers.
Some of the stereovison stuff in there, seems useful only when accessed from
inside Direct3D application. Unfortunately this does not help us much in
OpenGL.
Cheers,
Wojtek

That was my impression as well. 3D stereoscopic api seems to be created
for Direct3D developers to check if Stereo is running and
override/modify its parameters. The API is probably used to provide
native 3D Vision support from a DirectX game. I guess its used by
recently advertrised S3D aware Unreal.
Not really - the API is intended for tools like the NVIDIA control
panel, allowing you to tweak settings of the driver. It has nothing to
do with stereo as such, it actually predates the 3D Vision glasses by
quite a bit. It is used by the NVIDIA tools.
I am curiouse if NVAPI gives access to shutter glasses. If shutter
control is possible and possible is 120 hz refresh rate through display
settings, one could try emulate 3D stereo effect by alternate eye view
rendering. But thats a quite tricky solution either.
No, there are, if I recall correctly, only 3 functions allowing you to
change anything stereo-related: turn stereo on/off, set the eye
separation and set the focal distance (the distance of the eye from the
image plane). That is all.
The rest of the API is not related to 3D at all.
Regards,
Jan
