Random Triangles (p5js)
September 8th, 2021

Made some generative art today.

random triangles (sample)

Very basic stuff, but I've always been fond of this type of artwork. I'd like to do this more often and embed a widget to play with it directly in my website. But until then, paste the code below into the p5js editor at [editor.p5js.org](https://editor.p5js.org/) and hit "play" a few times to generate some results.

let s = 1000;
let overdraw = s * 0.4;
let randomBound = s + overdraw;

function setup() {
  createCanvas(s, s);
}

function draw() {
  background(255);

  for (let i = 0; i < 12; i++) {
    fill(randomColor());
    noStroke();
    randomTriangle();
  }
  noLoop();
}

function randomColor() {
  let myColor = color(random(255), random(255), random(255));
  while (saturation(myColor) > 50 || lightness(myColor) < 50) {
    myColor = color(random(255), random(255), random(255));
  }
  return myColor;
}

function randomValue() {
  return random(randomBound) - overdraw / 2;
}

function randomTriangle() {

  let dist12, dist23, dist13 = 0;
  let x1, y1, x2, y2, x3, y3 = 0;

  let thinThreshold = 300;

  while (dist12 < thinThreshold || dist23 < thinThreshold || dist13 < thinThreshold) {
    x1 = randomValue();
    y1 = randomValue();
    x2 = randomValue();
    y2 = randomValue();
    x3 = randomValue();
    y3 = randomValue();


    dist12 = Math.sqrt( Math.pow((x1-x2), 2) + Math.pow((y1-y2), 2) );
    dist23 = Math.sqrt( Math.pow((x2-x3), 2) + Math.pow((y2-y3), 2) );
    dist13 = Math.sqrt( Math.pow((x1-x3), 2) + Math.pow((y1-y3), 2) );
  }

  triangle(x1, y1, x2, y2, x3, y3);
}
