| Abstract: | An algorithm for constructing trigonometric spline curve which is tangent to the given polygon is described.The control points of the trigonometric spline to be constructed are computed simply by the vertices of the given polygon.The constructed curve is shape-preserving to the polygon.The local modification to the trigonometric spline curve can be completed by simply adjusting the corresponding control parameters.Two examples are given finally. |
