  • Polygon and polyline clipping for computer graphic displays
    Patent number: 5455897
    Abstract: A method of clipping polygons in two dimensions, in which if a vertex is outside a boundary line, the succeeding vertex is handled as it is also outside the same boundary line until determined to be otherwise, in which if a vertex is in the window, the succeeding vertex is handled as it is also in the window until determined to be otherwise. This method also produces the fewest vertices after clipping a polygon. A method for clipping polylines is also derived from this method.
