Hello Forum,
I have a LightManager class that tracks the number of lights(OpenGL Lights) that have been created. Inside the class the have the following member osg::ref_ptr<osg::Group> groupOfLights; vector<osg::ref_ptr<osg::LightSource> > lights; the member groupOfLights contain the LightSource as child. In the application i want to select different light (spot,point or diffuse) with key press event and only one light is enabled during an instant OR i may enable several lights. In that case i believe that i have to do dynamic casting to cast Group to Switch. In other better way to do that ? Regards Sajjad
