JavaScript implementation of Philip J. Schneider's "Algorithm for Automatically Fitting Digitized Curves" from the book "Graphics Gems". Converted from Python implementation.
Fit one or more cubic Bezier curves to a polyline. Works with 2D and 3D curves (and should work for higher dimensions too).
This is a JS implementation of Philip J. Schneider's C code. The original C code is available on http://graphicsgems.org/ as well as in https://github.com/erich666/GraphicsGems
Install
npm install --save @odiak/fit-curve
Usage
import { fitCurve } from '@odiak/fit-curve'
const points = [
{ x: 0, y: 0 },
{ x: 10, y: 10 },
{ x: 10, y: 0 },
{ x: 20, y: 0 }
]
const error = 50 // The smaller the number - the much closer spline should be
const bezierCurves = fitCurve(points, error)
// bezierCurves[0] === [ { x: 0, y: 0 }, { x: 20.27317402, y: 20.27317402 }, { x: -1.24665147, y: 0 }, { x: 20, y: 0 } ]
// where each element is {x, y} and elements are [first-point, control-point-1, control-point-2, second-point]Changelog
