Hi Kim, Have a look at the way osgdistortion works, it renders the scene to a texture that inherits the master cameras projection and view matrix. Then a slave camera works as in HUD style, with an absolute projection and view matrix to render the distorted mesh. You'll want to do something quite similar.
You could also have a look at the src/osgViewer/View.cpp implementations of the View::setUpViewFor3DSpehericalDisplay and setUpViewForPanoramicSphericalDisplay as they use a combination of relavative and absolute cameras to get the final result. In the mid-long term I'd like to see stereo support/novel display in the OSG all moved into osgViewer rather than osgUtil::SceneView as this will make it much easier to implement techniques like you are tackling in a coherent way to the way we enable other stereo modes. Doing at the high level also provide performance benefits. Robert.
