Hi Chris, The osg:Camera methods directly map to the equivalent OpenGL ones so what you are try should work. What may be going wrong is that if you have CameraManipulator attached to your viewer then it'll overwrite the Camera's ViewMatrix on each new frame. If you are using viewer.run() it'll assign a TrackballManipulator for you as fallback, but if you have your own viewer frame loop you'll be able to set the Camera's view matrix on each new frame as required.
