This is typically done by adding userdata, which happens to be supported by
each osg:Object (including nodes) in OpenSceneGraph.
>From source in osg::Object
Code:
/**
* Set user data, data must be subclassed from Referenced to allow
* automatic memory handling. If your own data isn't directly
* subclassed from Referenced then create an adapter object
* which points to your own object and handles the memory addressing.
*/
inline void setUserData(Referenced* obj) { _userData = obj; }
/** Get user data.*/
inline Referenced* getUserData() { return _userData.get(); }
/** Get const user data.*/
inline const Referenced* getUserData() const { return _userData.get(); }
