摘　　要：In this paper a new algorithm of B-spline curves with given tangnt polygons is discribed. In the algorithm the all de Boor points of the B-spline curves can be cal culated simply by the vertices of the given tangellt polygons. The constructed curves are shape-preserving to tangent polygons. The local modilications for thes curves are possible. At last several examples are given.In this paper a new algorithm of B-spline curves with given tangnt polygons is discribed.
