Besides inheriting the properties of classical Bezier curves of degree , the corresponding -Bezier curves have a good performance in adjusting their shapes by changing shape control parameter. In this paper, we derive an approximation algorithm for multidegree reduction of -Bezier curves in the -norm. By analysing the properties of -Bezier curves of degree , a method which can deal with approximating -Bezier curve of degree by -Bezier curve of degree is presented. Then, in unrestricted and , constraint conditions, the new control points of approximating -Bezier curve can be obtained by solving linear equations, which can minimize the least square error between the approximating curves and the original ones. Finally, several numerical examples of degree reduction are given and the errors are computed in three conditions. The results indicate that the proposed method is effective and easy to implement.
