Field Summary

long	duration how long should the whole zoom-in process take place (in milliseconds) ? 1000 * 2 = 2 seconds.
private double	scale_i values of position, zoom_in and tilt at the time of creation.
(package private) boolean	should_destroy if this is set to true then shouldDestroy will return true, do appropriate steps, and display method will destroy instance of this object by setting it to null.
private long	start_time time that this object was created.
private Coordinate	where Coordinate of where zooming in should zoom in to.
private double	x_disp_i values of position, zoom_in and tilt at the time of creation.
private double	xtilt_i values of position, zoom_in and tilt at the time of creation.
private double	y_disp_i values of position, zoom_in and tilt at the time of creation.
private double	ytilt_i values of position, zoom_in and tilt at the time of creation.
private double	z_disp_i values of position, zoom_in and tilt at the time of creation.
double	zdisp_f this is equivalent to how close the zoom_in should be when its done.

Constructor Summary

ViewPanel.zoomerInner(Coordinate where)
default constructor.

Method Summary

boolean	shouldDestroy() if this object should be destroyes, then set position and tilt values to their final ones, and return true so display method can destroy this object.
void	step() advance one step in zooming process.
