Hermite spline 已经有了 curve,其实 spline 的概念也就呼之欲出,spline 无非就是把 curve 一段一段连接起来,同时根据我们的要求满足G^1, G^2等不同的要求. 对于Python(numpy/scipy) 来说,有很多 spline 和 interpolate 的工具,比如 B样条 中已经出现过的。接下来利用BPoly.from_derivatives来 interpolate poin...
Cubic Hermite Curve大概最近和 Hermite Curve 和 Spline 磕上了,先回顾,再总结,首先回归 Hermite 曲线,它可以写成矩阵形式: H(t) = \begin{bmatrix} \mathbf{P}_1 & \mathbf{P}_2 & \mathbf{T}_1 &a…
Hermite插值是利用未知函数f(x)在插值节点上的函数值及导数值来构造插值多项式的,其提法为:给定n+1个互异的节点x0,x1,……,xn上的函数值和导数值求一个2n+1次多项式H2n+1(x)满足插值条件H2n+1(xk)=ykH'2n+1(xk)=y'k k=0,1,2,……,n ⒀如上求出的H2n+1(x)称为2n+1次Hermite插值函数,它与...
Here, a parametric design is discussed that uses a cubic Hermite spline (Zeid, 1991), one of the most common methods of representing curves and surfaces, for modeling. A cubic polynomial has four coefficients and thus requires four conditions for evaluation. These conditions could be a ...
