  • Patent number: 3944997
    Abstract: An image generator including a visible edge encoder which receives information defining the visible surfaces of a two-dimensional projection of a three-dimensional world and provides encoded two-dimensional visible edges which are x-ordered and are ready for transmission to a plurality of display terminals. The information received by the visible edge encoder defines the x and y intercepts, in successive planes which include the observer's eye and successive scanlines, of all three-dimensional edges which would be visible to the observer. The information provided by the visible edge encoder is edges which represent a two-dimensional projection of three-dimensional objects, each edge defined by its intended position on a two-dimensional screen and by attributes for a portion of the screen adjacent the edge, such as color, brightness, shading and the like.
