摘要：

An algorithmic approach to degree reduction of B-spline curves is presented. The method consists of the following steps: (a) decompose the B-spline curve into Bezier pieces on the fly, (b) degree reduce each Bezier piece, and (c) remove the unnecessary knots. A complete algorithm and precise error control are provided.
