OnLoad: this is the place to load resources from disk, like images or music.
OnUpdateFrame: this is a suitable place to handle input, update object positions, run physics or AI calculations.
OnRenderFrame: this contains the code that renders your graphics. It typically begins with a call to GL.Clear() and ends with a call to SwapBuffers.
OnResize: this method is called automatically whenever your game window changes size. Fullscreen applications will typically call it only once. Windowed applications may call it more often. In most circumstances, you can simply copy & paste the code from Game.cs.
the help at (http://www.opentk.net/doc/chapter/0) mentions these four methods to override and the quickstart uses them as well but does not call the base class OnLoad, OnUpdateFrame, OnRenderFrame, and OnResize
i guess it is not necessary to call those base class methods? thanks
