Noise

( In the student’s words )

The yellow line is the snowline. Everything else is noise.

( Make your own )

Start from the same numbers.

Type the parameters above into the Lab, then change one. It is the fastest way to learn what each one does.

// 01.6 Flow fields: every line follows the noise
const scale  =0.0028  // how far you zoom into the noise
const turns  =1.60  // how hard the lines curl
const lines  =2200  // how many lines to draw
const steps  =70  // how long each line runs
const weight =0.8  // stroke width in px
for (let i = 0; i < lines; i++) {
  let [x, y] = randomPoint()
  for (let s = 0; s < steps; s++) {
    const a = noise(x * scale, y * scale) * TAU * turns
    lineTo(x += cos(a), y += sin(a))
  }
  stroke(chalk, weight)
}
