Hi Robert, Do you mean the DrawCallback in the Camera class, which contains virtual void operator () (osg::RenderInfo& renderInfo) ? And here I can use the RenderInfo right?
As I know, the following code can get a contextID: camera->getGraphicsContext()->getState()->getContextID(); Is this contextID same as the upper one? And, Thank you!
