Hi JacaYang, You don't say what the problem you are seeing is. In general you are going the direction that should work, but there is too little information about how you assinging your callback or what the problems you are seeing are.
In general I'd say that integrating OpenGL code can be a bit awkward because both OSG OpenGL code and 3rd party OpenGL code change OpenGL state so they can influence each other. Robert.
