This class implements a frame-based Java3D behavior to allow for the engine to do update operations which have to take place every frame. Many internal engine objects are updated from this behavior.
To avoid threading problems and irregularities in timing, the engine uses just two behaviors and distributes update operations manual between objects: The time update occurs at a specified interval and is piped to the application to allow for animation update operations, while the frame update occurs after each frame and is used by the engine to do constant updates necessary.
