Hi Chris, Adrian et. al, I believe the right way to support this display is directly in the OSG itself, OpenGL wrappers are a really bad way to do it, both from a performance point of view and OpenGL state control point of view.
The way I'd add support is to use osgViewer's support for slave cameras on the same lines that I have implemented the distortion correction support that you'll find in src/osgViewer/Viewer.cpp:setUpView*() methods and the osgdistortion example. I'd also like to move all stereo/3d display support into osgViewer rather than low level in SceneView so any WowVX support would sit along side this. Robert.
