Abstract
A method and apparatus utilizes information describing linear line segments in terms (1) the horizontal scan line scan at which the line segment originates, (2) the horizontal position within the line of the point of origin, (3) the direction of the line segment, and (4) the horizontal scan line at which the line segment terminates to generate line segment information on a raster-scan type video display. The line segments can be combined to form polygonal areas that are capable of movement and changes in size or shape on the display.
