| Abstract: | An algorithm for constructing rational spline closed curve which is tangent to the given
polygon is described. The control points of the rational spline to be constructed are computed sim-
ply by the vertices of the given polygon. The constructed curve is shape-preserving to the poly-
gon. The local modification to the rational spline curve can be completed by simply adjusting the
corresponding control parameters. One example is given. |
