Test the size field for a VisibilitySensor node. A Sphere geometry has an associated VisibilitySensor in front of it, at point 0 0 0. The default ViewPoint is at point 0 0 10, looking down the -Z axis. Because the bounding box, with dimensions 4 4 4 is in direct sight, an isActive event is generated by the enabled VisibilitySensor node, which is routed to enable a TimeSensor node, which starts a color animation of the Sphere. When the user moves to the second viewpoint, behing the bounding box, at point 0 0 -10, an isActive=false event is generated and the Sphere ceases to change color. |
