Pen Plotting

Test everything on crappy paper first

Use canvas2svg for

easy vector outputs from canvas drawings

const size = 1000

const canvas = document.createElement('canvas')
canvas.width = size
canvas.height = size
document.body.appendChild(canvas)
const context = canvas.getContext('2d')

context.strokeStyle = '#fff'
context.lineWidth = 5
context.lineCap = 'round'

const u = size / 20
context.beginPath()
for (let i = 0; i < 100; i++) {
  const x = i%10
  const y = Math.floor(i/10)
  const rotations = (i%3 === 0 && 1) + (i%4 === 0 && 2)
  context.save()
  context.translate(u+x*u*2, u+y*u*2)
  context.rotate(rotations * Math.PI / 2)
  context.moveTo(-u, u)
  context.quadraticCurveTo(-u, -u, u, -u)
  context.restore()
}
context.stroke()
const size = 1000

import saveAs from 'file-saver'
import C2S from 'canvas2svg'


const context = new C2S(size, size)

context.strokeStyle = '#fff'
context.lineWidth = 5
context.lineCap = 'round'

const u = size / 20
context.beginPath()
for (let i = 0; i < 100; i++) {
  const x = i%10
  const y = Math.floor(i/10)
  rotations = (i%3 === 0 && 1) + (i%4 === 0 && 2)
  context.save()
  context.translate(u+x*u*2, u+y*u*2)
  context.rotate(rotations * Math.PI / 2)
  context.moveTo(-u, u)
  context.quadraticCurveTo(-u, -u, u, -u)
  context.restore()
}
context.stroke()

const blob = new Blob([context.getSerializedSvg()], {
  type: 'text/plain',
})
saveAs(blob, 'pattern.svg')

Beyond Tellerrand Berlin 2019 - Taking The Web Off The Screen

Beyond Tellerrand Berlin 2019 - Taking The Web Off The Screen

Most web developers don’t get the joyous experience of touching and feeling the things they’ve created. Interest in generative art on the web is at an all-time high, but predominantly confined to screens and pixels, without much room for tactility. Through her unwavering enthusiasm for making physical things, Charlotte will demonstrate a myriad of ways you can use your coding prowess to make art in the physical realm.
