    Catenary Curve - Calculate the ideal catenary between two points

    Given two points and a length, this library will calculate and draw the catenary between two points, the "correct" way, so that it behaves natural (technically).

    How to use

    import { Catenary, Point } from 'catenary-curve'
     
    // This is optional, you can also use a simple { x: 200, y: 300 } object.
    let p1 = new Point(200, 300)
    let p2 = new Point(250, 400)
     
    let chain = new Catenary({
      segments: 50,
      iterationLimit: 100
    })
     
    const context = canvas.getContext('2d')
     
    // The drawToCanvas function will only call the actual draw function (moveTo,
    // lineTo, quadraticCurveTo), so you have to call beginPath() and stroke()
    // yourself.
    context.beginPath()
    context.lineWidth = 1
    context.strokeStyle = 'black'
    chain.drawToCanvas(context, p1, p2, 500)
    context.stroke()

    Acknowledgement

    The basis of this library is an ActionScript by poiasd, originally released on wonderfl.net, archived and preserved at http://wa.zozuar.org/code.php?c=8Bnl.

    Unfortunately I wasn't able to find out who the original author was and ask them if and how they want to be mentioned/linked.
