For creating a stereo-in-a-window canvas in GTK (with Python that is) I had to step away from using setUpViewerAsEmbeddedInWindow, as this function creates a new osgViewer::GraphicsWindowEmbedded with parameters (x,y,width,height). This results in a "default" graphics context setup without specific settings, e.g. stereo. I now sort of mimic setUpViewerAsEmbeddedInWindow by making an osg::Traits instance, set the traits->quadBufferStereo to true, and pass this to osgViewer::GraphicsWindowEmbedded (which is already overloaded to accept a Traits instance). This gives me a working stereo canvas. Hope this works for you.
Gerwin P.s. be sure that your graphics card supports QUAD_BUFFER stereo in a (non-fullscreen) window on your OS (for example, you have a nVidia Quadro card on linux) On Mon, Aug 25, 2008 at 9:07 PM, Yanling Liu <[EMAIL PROTECTED]> wrote: > Hi, I was trying to enable QUAD_BUFFER stereo in my OSG based application > but failed.
