摘要：
This paper proposes an approach of constructing planar piecewise Bezier curve of 4th or 5th degree with all edges tangent to a given control polygon and the curve segments are joined together with C2 and C3 continuity. The segmented Bezier curves are all shape-preserving to their tangent polygon. Finally, a few numerical examples illustrate that the method given in this paper is effective for CAGD.
