Hi Otto, To use VBO's in OSG, you just need to set up an osg::Geometry as you normally would and then call:
geometry->setUseDisplayList( false ); //Disable display lists geometry->setUseVertexBufferObjects( true ); //Enable VBO After that everything is handled under the hood for you, you can look at the osgTerrain library or the osgdrawinstanced example for examples.
