  abstract =     "Cubic spline curves have many nice properties that
                 make them desirable for use in computer graphics, and
                 the advantages of antialiasing have been known for some
                 years. Yet, only recently has there been any attempt at
                 directly antialiasing spline curves. Parametric spline
                 curves have resisted antialiasing in several ways:
                 single segments may cross or become tangent to
                 themselves. Cusps and small loops are easily missed
                 entirely. Thus, short pieces of the curve cannot
                 necessarily be rendered in isolation. Finding the
                 distance from a pixel center to the curve accurately
                 and efficiently---usually an essential part of
                 antialiasing---is an unsolved problem. The method
                 presented by Lien, Shantz, and Pratt [21] is a good
                 start, although it considers pixel-length pieces of the
                 curve in isolation and lacks robustness in the handling
                 of certain curves. This paper provides an improved
                 method that is more robust, and is able to handle
                 intersections and tangency.",
