when the program starts, the light on the laser jitter does not turn on at all!
I have enabled the ss option in the control panel
Does opengl really work for 3D vision on windows? Could anyone provide a sample code please?
Thank you!

I think officially Quad Buffer OpenGL should only work on Quadro cards (not Geforce).

However, there was a post around here where someone said they got it to work on normal Geforce cards (and I tried it and confirmed).

I don't think it will just work with any old OpenGL app (like a compiled game).

If you are making your own app you would probably need to use a Quad Buffer render and maybe integrate something with the NV API.

To be honest, I don't have much experience with OpenGL so I am not really sure.

Actually I AM using Quadro 2000...
Seems that directx is a natural choice for 3D vision, and much difficulties and uncertain factors exist for opengl, is that true?

Well there is certainly more action on the 3D front for DirectX, but OpenGL should be supported too.

I think the post you are refering to is this one:
http://www.mtbs3d.com/phpbb/viewtopic.php?f=105&t=16849

I haven't done it yet, but I have a feeling that to get this to work you need to (at least):
1) Allocate an OpenGL context that supports GL_STEREO.
2) Run your application in full screen mode using glutEnterGameMode()
3) Programmaticaly compute left and right eye viewpoints, and render the results after calls to glDrawBuffer(GL_BACK_LEFT) and glDrawBuffer(GL_BACK_RIGHT), respectively.
4) 3D Vision must be enabled, and monitor refresh rate must be set to 120 Hz (manually before each program launch)
