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.'/>

Event Graph ROUTE Table entries with 2 ROUTE connections total, showing X3D event-model relationships for this scene.

Each row shows an event cascade that may occur during a single timestamp interval between frame renderings, as part of the X3D execution model.
