Helps create harmonograph style patterns.

setup

Fetch latest from GitHub directly:

npm i thewhodidthis/swing

usage

Pass in at a minimum amplitude and frequency arguments and call the resulting function over time. For example,

import swing from '@thewhodidthis/swing'

// Lissajous curve wrapper (no damping)
const driver = (A = 1, B = A, a = 1, b = a * 2, phase = Math.PI * 0.5) => {
  const x = swing(A, a, phase)
  const y = swing(B, b, phase)

  return t => ({ x: x(t), y: y(t) })
}

// Points for Lemniscate of Gerono
const lookup = driver(175, 100)

setInterval(() => {
  const t = Date.now()
  const { x, y } = lookup(t)

  console.log(x, y)
}, 1000)
