Public Member Functions
virtual void	init ()
	Initializes the scene. It is called by CGFapplication when the scene is associated through CGFapplication::setScene()
virtual void	display ()
	Renders the scene. When this scene is active in the current application, it is called by CGFapplication::display(), which in turn is registered as GLUT display handler, thus being called at every frame refresh.
virtual void	update (unsigned long millis)
	Periodic update function. This is a generic update handler for use in animations. It is called periodically at the time interval set with setUpdatePeriod(). When called, receives as parameter the actual timestamp in millisseconds, to be used in animations and other computations.
virtual void	initCameras ()
	Initializes default cameras. Usually called at the end of the constructor.
void	activateCamera (int i)
	If a default set of cameras is available in scene_cameras, activates the camera at position i
void	setInterface (CGFinterface *i)
	Registers a CGFinterface instance with this scene. This is typically called by CGFapplication when a CGFinterface is registered through CGFapplication::setInterface()

Protected Member Functions
void	setUpdatePeriod (unsigned long millis)
	Sets the update period between each call to update(), in milliseconds. if millis=0, updates are disabled.
void	checkUpdate ()
	Called by the main application class, that handles timing, to check if an update is needed due to timeout. If so, it calls update(), and updates the timer.
