Perlin noise is a type of gradient noise developed by Ken Perlin in 1983 as a result of his frustration with the "machine-like" look of computer-generated imagery (CGI) at the time. He formally described his findings in a SIGGRAPH paper in 1985 called An image Synthesizer. In 1997, Perlin was awarded an Academy Award for Technical Achievement for creating the algorithm.

## #The algorithm

p5-perlin-noise.js`p.stroke(`rgba(0,0,0,0.4)`); p.strokeWeight(1); p.beginShape(); let xOffset = 0.0; let step = 10; for (let x = constraints[0]; x < constraints[1] + step / 2; x += step) { let y = p.map(p.noise(xOffset, yOffset), 0, 1, constraints[0], constraints[1]); p.vertex(x, y); xOffset += 0.03; } yOffset += 0.01; p.endShape();`
