Hi Gang, You'll need to write a custom NodeVisitor that traverses down to the Geode's in the scene graph then gets its Drawables, then from cast to Geometry and then query it's info. There dozens of examples osg NodeVisitor's in the OSG code base that do similar things to this so I recommend you just search from places which subclass from osg::NodeVisitor.
