摘要
本文选择累加弦长作为插值曲线的参数,给出插值节点处切向的决定方法,得到平面上一类C^2连续和保凸的插值样条曲线。这类曲线具有较好的光顺性,且方法和公式简明,是一类有实用价值的样条曲线。
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.
