Re: [osg-users] Rendering OSG objects inside an existing OpenGL loop

You can render GL objects creating an osgNode and overwriting the drawing call.There is an example how to do it in the OSG CookBook of Packt Publishing.I dont remember if there is a demo in the exmaples though. On Friday, March 4, 2016 11:23 AM, Clement Begotto
