Package Exports

cubic-parametric-spline

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cubic-parametric-spline) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

三次参数样条函数，在三次样条函数基础上可以适应非递进式数据

installation

npm install cubic-parametric-spline

usage

import SPLINE from "cubic-parametric-spline"

const p = [[0,0],[0,2],[3,2]];//点集合
const p_ =[[-1,1],[],[2,-1]];//端点矢切，只对两端提供，中间点对应位空数组

// new a Spline object
const spline = new SPLINE(p, p_);

// 通过输入参数（指和点i距离为t的坐标）获取曲线上某一点
spline.caculate_point(i,t)

// 以1为间隔得到曲线上的诸点,方便绘制曲线
spline.grasp_sample();
console.log(spline.samples_s)
