ABSTRACT:
Antialiased lines are generated in a computer graphics system by drawing the pixels on one side of the ideal line segment in the minor axis direction on one pass and drawing the pixels lying on the other side of the line segment in the minor axis direction on another pass. A modified Bresenham procedure is used to generate the pixel positions on both passes. On either pass, intensity values are generated from the integral Bresenham determinant directly, rather than from the perpendicular or vertical distance between the pixel and the line.
