<meta name='description' content='Test the fraction_changed field of a TimeSensor node. Two TimeSensors with cycleIntervals of 2 and 4 seconds animate a blue and green Sphere geometry respectively along the same distance. Because the cycleInterval of one TimeSensor is half that of the other, the fraction_changed events are routed to one PositionInterpolator twice as fast as the other TimeSensor, and the blue Sphere completes its animation twice as fast as the green Sphere. To verify this, click on the red Sphere to start the animation.'/>
