After giving the legendre polynomials approximation to parametric speed of the curve , the author gives the jacobi polynomials approximation to parametric speed with endpoints interpolation . from this , two algebraic offset approximation algorithms , which preserve the direction of normal , are derived
给出了曲线参数速度的legendre多项式逼近，进一步给出了参数速度的插值区间端点的jacobi多项式逼近，由此导出了保持法矢平移方向的两个等距代数有理逼近算法
