摘要：
We present an efficient method to solve the problem of the constrained least squares approximation of the rational Bezier curve by the polynomial Bezier curve. The presented algorithm uses the dual constrained Bernstein basis polynomials, and exploits their recursive properties. Examples are given, showing the effectiveness of the algorithm.
