16 | <meta name='description' content='Test overlapping VisibiltySensors. Two unique VisibilitySensor nodes are associated with two unique Sphere geometry. The left VisibilitySensor (whose bounding box is represented by the IndexedLineSet box), should route its events to change the Color of the left Sphere from white to blue when the viewers avatar enters its bounding box. The right VisibilitySensor should change the color of the right Sphere from white to red when activated. The central "overlapping" area, when visible, by the viewers avatar, should concurrently activate both VisibilitySensors, and generate separate events for both of them. When viewpoints take the viewer avatar behind all of the bounding boxes, the color animation of the Sphere should stop.'/> |
