100x100 Computational Design Challenge

Throughout 2020 I created 100 computational designs in 100 days as a way to learn creative coding and explore generative art

Day 67 - Lamp Shades

Today’s sketch is another happy accident I stumbled upon as I tried to do the actual thing I thought I wanted to do this week. Playing around with trigonometry, I’m delighted with how these delicate shapes unexpectedly came together. I also like the optical illusion a lot of the drawings create as my brain flip flops trying to figure out their orientation.

Drawings:

Code:

xoff = 0;
i = 0;
y1 = 0;

function setup() {
  createCanvas(800, 800);
  background(255, 235, 237);
  noFill();
}

function draw() {

  translate(width / 2, height / 2);
  stroke(random(80));
  xoff = xoff + 0.01;
  n = noise(xoff) * 2;

  var radius = 400;
  var angle = TAU / 100;
  var x = cos(angle * i) * radius;
  var y = cos(angle * i) * radius;
  i = i + 0.1;

  ellipse(0, y1, x * n, y * n);
  y1 = y1 - 1;

  if (y1 < -250) {
    noLoop();
  }
}
