Example 12 — color output

Wave Color Field

Two wave samplers with shift: true drive hue and brightness across a 2D field. Every 4 seconds the formulas morph into new ones over 2 seconds — the colour landscape keeps evolving.

Core snippet

var hueSampler = Waves.createSampler({
  wave: 'meta sine', shift: true,
  shiftInterval: 4, shiftDuration: 2,
  range: [160, 320], seed: 0
});
var briSampler = Waves.createSampler({
  wave: 'wobble sine', shift: true,
  shiftInterval: 5, shiftDuration: 2,
  range: [55, 90], seed: 7
});

// In draw:
for (var y = 0; y < height; y += 4) {
  for (var x = 0; x < width; x += 4) {
    fill(hueSampler.sample(x*0.007 + y*0.005, t),
         72,
         briSampler.sample(x*0.005 - y*0.007, t*0.6));
    rect(x, y, 4, 4);
  }
}
