I am doing dynamic geometry with OSG. See a gif-animation here: http://raumgeometrie.de/drupal/de/node/48 (the original is much more fluent). But, as far as I know, you will have to code the deformations yourself (at least I do so). The reals strength of a scenegraph is, I think, large scenes which stay at least partially static. Thus you will not get a real speedup by using a scenegraph, but you might profit from using osg just as a realtime graphics library, which makes coding much easier than using pure OpenGL. When I started using osg, I just used it like some object oriented GLUT. In your case, multiple cameras might be of interest, and lots of other stuff. But, as I said, highly dynamic scenes are not the main purpose of a scenegraph.
