Abstract

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 occurs when a computer graphic object represented by computer graphics, e.g., in front of, to the side, above, or below the video screen, undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, because such an object would disappear from view by the viewer. This limitation is overcome by having such an object be represented as video on the screen, rather than computer graphics. Thus, the computer graphics object "goes into the video" as video and remains visible to a viewer in front of the video screen, rather than becoming invisible because it is blocked from view by the video screen if it were to be generated at its proper location using computer graphic techniques.
