<meta name='descriptioncontent='Two unique (not instances of) ProximitySensor node are associated with two unique Sphere geometry. The left ProximitySensor (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 ProximitySensor should change the color of the right Sphere from white to red when activated. The central "overlapping" area, when entered by the viewers avatar, should concurrently activate both ProximitySensors, and generate seperate events for both of them. The result is, both Spheres should change from white to their respective colors of blue (left) and red (right).'/>
