ABSTRACT:
Method and apparatus for drawing vectors on limited precision display devices in amounts of time approximately proportional to the vector's geometric length. Vectors are drawn by a series of strokes. Each stroke is a series of counter control signals, each signal representing a vertical, horizontal, or diagonal movement of the CRT electron beam between adjacent addressable screen points. The counter control signals making up the strokes are stored on a look-up table.
