A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen is that when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, namely, any portion of the object that is no longer on the video screen disappears. To overcome this limitation, when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, such an object, or portion thereof, is made to continue to be visible to the user by representing it at the foreground location to which its trajectory was carrying it using computer graphic techniques, rather than video. Thus, the video object "pops" out of the video and becomes visible, e.g., in front of, or to the side of, the video screen, rather than becoming invisible because it is no longer on the video screen.
