Questions to Stereo API
Does anyone know what are the valid value ranges for eye separation and convergence in functions:
virtual float SetSeparation(float);
virtual float SetConvergence(float);

I didn't find the information in the nvidia sdk documentation. Neither from the internet or nvidia forums.

Maybe 0.0 to 1.0 but its a simple try :)

[0, 1] might be for separation but certainly not for convergence which seems to be a distance from viewer.

Could be an angle also! But i think youre right.
Another idea: try to get the Value by GetConv. in a KeyHandler and send it to an output.


Sorry my bad english!

I just wonder why nvidia hasn't documented it and lets its users make random guesses...

StereoI is part of nvidia SDK, right?!

I think so, cause the 'normal' way, described [url="http://www.stereographics.com/support/developers/pcsdk.htm"]here[/url], does not use that Interface.
Youre right, its really hard to find some information about that :(

Convergence - Z coordinate of null parralax plane
Separation - describe percent of offset in X axis from screen center.
For example, when set separation 30% and 19'' monitor NVidia use that value 0.05121 = 0.001707 * 30

Hope this is understandable with my English :-)
