| Abstract: | Repeated length of chord was selected as the parametre of the interpolation curve and the direction of tangent vector of the curve at link point was decided. In this way, a kind of C2 continuous convex interpolation spline curve on a place was obtained in this paper.Sucb a curve,which has better light-fairness, is of great value in practice because this method and formula are simple. |
