2.Improved algorithms of a line with thickness of three pixels with antialiasing are presented based on the principle of aliasing and Wu antialiasing and Gupta & Sproull cone filtering algorithms. These improved algorithms are applied to the scale line drawing of a compass for cockpit display system. Experimental results of the high quality straight line with antialiasing show that the algorithms are successful.
