Hi Yanling, Yuu can't use a standard OpenGL visual to do quad buffer stereo, you'll need to create a context with a visual that explicitly support quad buffer stereo. The GraphicsContext support in osgViewer does support quad buffer where this visual is supported by the underlying OpenGL driver/hardware, so I'd recommend just using this route, at least as an initial test to see if you can get quad buffer stereo work. A quick test would be :
osgviewer cow.osg --stereo QUAD_BUFFER Robert.

I can pass --stereo QUAD_BUFFER to the osgViewer > application to enable stereo on my machine.
