The touchTime event of the TouchSensor associated with the white Sphere is routed to the startTime field of a TimeSensor. The TimeSensor fields drive a PositionInterpolator that animates the movement of the white Sphere. When the pointing device indicates the white Sphere (by pressing down on the primary pointing device button while its bearing intersects the white Sphere geometry, then releasing the button while still over the white Sphere), the Sphere should begin to move.'/>
