Common Patterns
Flow Field
let cols, rows;
let scale = 20;
let particles = [];
let flowfield;
function setup() {
createCanvas(800, 600);
cols = floor(width / scale);
rows = floor(height / scale);
flowfield = new Array(cols * rows);
for (let i = 0; i < 1000; i++) {
particles.push(new Particle());
}
background(20);
}
function draw() {
let yoff = 0;
for (let y = 0; y < rows; y++) {
let xoff = 0;
for (let x = 0; x < cols; x++) {
let index = x + y * cols;
let angle = noise(xoff, yoff) * TWO_PI * 2;
let v = p5.Vector.fromAngle(angle);
v.setMag(1);
flowfield[index] = v;
xoff += 0.1;
}
yoff += 0.1;
}
for (let particle of particles) {
particle.follow(flowfield);
particle.update();
particle.edges();
particle.show();
}
}
class Particle {
constructor() {
this.pos = createVector(random(width), random(height));
this.vel = createVector(0, 0);
this.acc = createVector(0, 0);
this.maxspeed = 2;
this.prevPos = this.pos.copy();
}
follow(vectors) {
let x = floor(this.pos.x / scale);
let y = floor(this.pos.y / scale);
let index = x + y * cols;
let force = vectors[index];
this.applyForce(force);
}
applyForce(force) {
this.acc.add(force);
}
update() {
this.vel.add(this.acc);
this.vel.limit(this.maxspeed);
this.pos.add(this.vel);
this.acc.mult(0);
}
show() {
stroke(255, 5);
strokeWeight(1);
line(this.pos.x, this.pos.y, this.prevPos.x, this.prevPos.y);
this.prevPos = this.pos.copy();
}
edges() {
if (this.pos.x > width) { this.pos.x = 0; this.prevPos = this.pos.copy(); }
if (this.pos.x < 0) { this.pos.x = width; this.prevPos = this.pos.copy(); }
if (this.pos.y > height) { this.pos.y = 0; this.prevPos = this.pos.copy(); }
if (this.pos.y < 0) { this.pos.y = height; this.prevPos = this.pos.copy(); }
}
}
Recursive Tree
function setup() {
createCanvas(600, 600);
background(20);
stroke(255);
translate(width/2, height);
branch(120);
}
function branch(len) {
strokeWeight(map(len, 10, 120, 1, 8));
line(0, 0, 0, -len);
translate(0, -len);
if (len > 10) {
push();
rotate(PI/6 + random(-0.1, 0.1));
branch(len * 0.7);
pop();
push();
rotate(-PI/6 + random(-0.1, 0.1));
branch(len * 0.7);
pop();
}
}
Circle Packing
let circles = [];
let maxAttempts = 1000;
function setup() {
createCanvas(600, 600);
background(20);
noLoop();
}
function draw() {
for (let i = 0; i < 500; i++) {
addCircle();
}
for (let c of circles) {
noFill();
stroke(random(200, 255), random(100, 200), random(150, 255));
strokeWeight(2);
ellipse(c.x, c.y, c.r * 2);
}
}
function addCircle() {
for (let attempts = 0; attempts < maxAttempts; attempts++) {
let x = random(width);
let y = random(height);
let r = random(5, 50);
let valid = true;
for (let c of circles) {
let d = dist(x, y, c.x, c.y);
if (d < r + c.r + 2) {
valid = false;
break;
}
}
if (valid) {
circles.push({x, y, r});
return;
}
}
}
Noise Landscape
let cols, rows;
let scl = 20;
let w = 1400;
let h = 1000;
let flying = 0;
let terrain = [];
function setup() {
createCanvas(600, 600, WEBGL);
cols = w / scl;
rows = h / scl;
for (let x = 0; x < cols; x++) {
terrain[x] = [];
}
}
function draw() {
flying -= 0.05;
let yoff = flying;
for (let y = 0; y < rows; y++) {
let xoff = 0;
for (let x = 0; x < cols; x++) {
terrain[x][y] = map(noise(xoff, yoff), 0, 1, -100, 100);
xoff += 0.1;
}
yoff += 0.1;
}
background(0);
stroke(255);
noFill();
translate(0, 50);
rotateX(PI/3);
translate(-w/2, -h/2);
for (let y = 0; y < rows - 1; y++) {
beginShape(TRIANGLE_STRIP);
for (let x = 0; x < cols; x++) {
vertex(x * scl, y * scl, terrain[x][y]);
vertex(x * scl, (y + 1) * scl, terrain[x][y + 1]);
}
endShape();
}
}
Color Palettes for Generative Art
// Palette 1: Sunset
const sunset = ['#FF6B6B', '#FEC89A', '#FFD93D', '#6BCB77', '#4D96FF'];
// Palette 2: Ocean
const ocean = ['#0F4C75', '#3282B8', '#BBE1FA', '#1B262C', '#00A8CC'];
// Palette 3: Forest
const forest = ['#1A4314', '#4E9F3D', '#8FD14F', '#F0EBE3', '#3B6064'];
// Usage
function getRandomColor(palette) {
return palette[floor(random(palette.length))];
}
Best Practices
- Use seeds - randomSeed() and noiseSeed() for reproducibility
- Layer effects - Build complexity through layering
- Limit iterations - Balance detail with performance
- Export high-res - Use pixelDensity(2) or higher
- Document parameters - Comment what each value controls
- Create variations - Change seed to explore possibilities
