## Discussion

This method causes your drawing method to be called immediately and then presents the rendered image to the screen. Your application typically calls this method inside of a rendering loop, such as the one provided by the [`GLKViewController`](/documentation/GLKit/GLKViewController) class, in order to provide a continuous smooth animation.

Never call this method inside your drawing function.
