public class isactive
extends java.lang.Object

A VisibilitySensor should generate an isActive event of true when the VisibilitySensor bounding box is in the field of view. A default Viewpoint places the viewer avatar directly in front of a VisibilitySensor bounding box, represented by a white IndexedLineSet. As a result, an isActive true event is sent to a TimeSensor to start a color animation of the Sphere geometry directly behind the bounding box. Moving to the second Viewpoint directly behind the bounding box should stop the color animation.
