Hi, That is an extremely general question. The essense of OSG is accessing and manipulating that information: it's used for dispatching OpenGL rendering commands, and for reading/writing a scenegraph to basically any file format. Have a look at the query methods of osg::Geometry and how an osgDB::ReaderWriter serializes it to a file. Use a NodeVisitor to find the Geometrys in the scene.
