Hi David, The viewer has the masster Camera, to get the view martrix it's simple a case of:
viewer.getCamera()->getViewMatrix(); As for your seg fault, there isn't anyone can tell you exactly what wrong with no code in front of them, there are lots different mistakes you could have made. It would probably be best to go read the Quick Start Guide, you can download it as a pdf, just follow the links from the download page on openscenegraph.org. Robert.
