Noise

( In the student’s words )

The mountain I see from my kitchen, as ninety lines of noise.

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-field.js

// 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)
}
