Also i wanted to clarify that when i tried to use the command line : osgviewer cow.osg --stereo QUAD_BUFFER it gives me the following : Warning: Could not find plugin to read objects from file "QUAD_BUFFER".

By default the OSG will use anaglyphic stereo when you enable stereo, but it also supports a range of other stereo options. For shutter glasses you'll probably just need to request quad buffer stereo via: osgviewer cow.osg --stereo QUAD_BUFFER For more command line details run osgviewer --help And via env vars: osgviewer --help-env Programatically you can enable stereo via osg::DisplaySettings (the above command line options and env vars just set it.) See the osgstreoimage example for an example of programmatically enabling stereo. There is a big but... and that's does you graphics card/OpenGL driver support quad buffer stereo. I can't answer this as you've provide no info w.r.t hardware/drivers you are using. For NVidia it's just their Quadro line that supports quad buffer stereo. Robert.
