Hi Clement,
  This is rather easy to do. All you need is to define a NodeVisitor and run it on the group. Using this way you only need to have an accept call for the Geode and process the drawables under the Geode.


class InfoVisitor : public osg::NodeVisitor
        setTraversalMode( osg::NodeVisitor::TRAVERSE_ALL_CHILDREN );

    void apply( osg::Geode& geode )
        for ( unsigned int i=0; i<geode.getNumDrawables(); ++i )
           // Do what you have to do, for example store in a data structure

     osg::Group * yourGroup = ...;
     InfoVisitor visitor;

    // After it completes you can retrieve your data structure.


Hope this helps.
