<meta name='descriptioncontent='Test of the "center" field of a VisibilitySensor node. A VisibilitySensor (represented by an IndexedLineSet box) is in front of a red Sphere geometry. The "center" field of the VisibilitySensor is located at -100 -100 100 in the world coordinate system. A Viewpoint of -110 -100 110 places the view directly in front of the VisibilitySensor. Directly behind the VisibilitySensor is a Sphere geometry. The VisibilitySensor should generate an isActive true event and begin a color animation of the Sphere. When the viewer moves to the second Viewpoint, behind the bounding box, the color animation should stop.'/>
