Colosseum3D is a VR framework built ontop of the OpenSceneGraph and a number
of other open source and closed source toolkits.
Delta3D is another open source framework/engine that similiarily sits upon
OpenSceneGraph for graphics, and then other open source toolkits for other
features.
There other frameworks/engines too that sit ontop of OpenSceneGraph, as to
what to use its all down to the type of app you are planning to develop.

osgVortex integrates OSG and Vortex, Vortex is developed as closed source by
CMLabs so you'll have to purchase a license. It is well recongised as one
of the best physics engines in the business.

Can't comment on this, I'm not familiar at the code/usage level of
Colossem3D.

There are the osgCal, Replicant and osgCharacter projects sitting on the
community section of the website.
