## Algorithmic Philosophy Creation
### The Critical Understanding
Algorithmic art isn't about randomness—it's about **encoded aesthetics**. Each piece should have a clear philosophical foundation that drives every visual decision.
### How to Generate an Algorithmic Philosophy
```
Before writing any code, define your PHILOSOPHY:
1. **Core Concept**
What abstract idea drives this piece?
- Emergence from chaos
- Tension between order and disorder
- Growth and decay
- Connection and isolation
2. **Visual Language**
How does the concept manifest visually?
- Particle density and distribution
- Color relationships
- Motion characteristics
- Spatial organization
3. **Mathematical Foundation**
What algorithms express the philosophy?
- Perlin/Simplex noise for organic flow
- Fibonacci/golden ratio for natural beauty
- Attractors for dynamic systems
- Cellular automata for emergence
```
### Philosophy Examples
```
Example philosophies to inspire:
1. "EMERGENCE"
- Particles follow simple rules
- Complex patterns arise naturally
- No central control, only local interactions
- Colors shift with density
2. "TENSION"
- Opposing forces in balance
- Particles attracted and repelled
- Sharp contrasts in color
- Dynamic equilibrium
3. "GROWTH"
- Branching structures
- Self-similar patterns
- Organic, tree-like forms
- Time as a dimension
```
## p5.js Implementation
### Essential Technical Requirements
```javascript
// Always use seeded randomness for reproducibility
function setup() {
randomSeed(42); // Same seed = same output
noiseSeed(42);
createCanvas(800, 800);
}
// Core requirements:
// 1. Deterministic output with seeds
// 2. Smooth animations at 60fps
// 3. Responsive canvas sizing
// 4. Color palette coherence
```
### Flow Field Pattern
```javascript
// Classic flow field with particles
let particles = [];
let flowField;
let cols, rows;
let scale = 20;
let inc = 0.1;
let zoff = 0;
function setup() {
createCanvas(800, 800);
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() {
// Update flow field with Perlin noise
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, zoff) * TWO_PI * 4;
let v = p5.Vector.fromAngle(angle);
v.setMag(1);
flowField[index] = v;
xoff += inc;
}
yoff += inc;
}
zoff += 0.002;
// Update and display particles
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();
this.hue = random(200, 260); // Blue-purple range
}
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];
if (force) 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(this.hue, 80, 90, 10);
strokeWeight(1);
line(this.pos.x, this.pos.y, this.prevPos.x, this.prevPos.y);
this.updatePrev();
}
updatePrev() {
this.prevPos = this.pos.copy();
}
edges() {
if (this.pos.x > width) {
this.pos.x = 0;
this.updatePrev();
}
if (this.pos.x < 0) {
this.pos.x = width;
this.updatePrev();
}
if (this.pos.y > height) {
this.pos.y = 0;
this.updatePrev();
}
if (this.pos.y < 0) {
this.pos.y = height;
this.updatePrev();
}
}
}
```
### Particle System Pattern
```javascript
// Attractor-based particle system
class Attractor {
constructor(x, y, strength) {
this.pos = createVector(x, y);
this.strength = strength;
}
attract(particle) {
let force = p5.Vector.sub(this.pos, particle.pos);
let distance = constrain(force.mag(), 5, 50);
let strength = this.strength / (distance * distance);
force.setMag(strength);
return force;
}
}
// Multiple attractors create complex dynamics
let attractors = [
new Attractor(200, 200, 500),
new Attractor(600, 200, -300), // Repeller
new Attractor(400, 600, 400)
];
```
### Color Palette Strategies
```javascript
// Curated color palettes for cohesion
const PALETTES = {
sunset: [
[255, 107, 107],
[255, 159, 67],
[254, 202, 87],
[29, 209, 161]
],
midnight: [
[15, 32, 39],
[32, 58, 67],
[44, 83, 100],
[168, 218, 220]
],
neon: [
[255, 0, 128],
[0, 255, 255],
[255, 255, 0],
[128, 0, 255]
]
};
function getColor(palette, index) {
let colors = PALETTES[palette];
return colors[index % colors.length];
}
function lerpPalette(palette, t) {
let colors = PALETTES[palette];
let scaled = t * (colors.length - 1);
let i = floor(scaled);
let f = scaled - i;
let c1 = colors[i];
let c2 = colors[min(i + 1, colors.length - 1)];
return [lerp(c1[0], c2[0], f), lerp(c1[1], c2[1], f), lerp(c1[2], c2[2], f)];
}
```
## Interactive Artifact Creation
### What's Fixed vs Variable
```
FIXED (Part of the artwork):
- Color palette
- Algorithm structure
- Visual style
- Animation speed
VARIABLE (User can adjust):
- Random seed
- Particle count
- Flow field resolution
- Zoom/pan
```
### Required Interactive Features
```javascript
// Keyboard controls
function keyPressed() {
if (key === 's') {
saveCanvas('artwork', 'png');
}
if (key === 'r') {
// New random seed
randomSeed(millis());
noiseSeed(millis());
setup();
}
if (key === 'p') {
// Pause/play
isPlaying = !isPlaying;
isPlaying ? loop() : noLoop();
}
}
// Mouse interaction
function mousePressed() {
// Add attractor at mouse position
attractors.push(new Attractor(mouseX, mouseY, 300));
}
```

## Best Practices
1. **Start with Philosophy**: Define the concept before coding
2. **Use Seeded Randomness**: Enable reproducible outputs
3. **Layer Effects**: Build complexity through simple layers
4. **Constrain Palettes**: Limited colors create cohesion
5. **Add Interactivity**: Let viewers explore variations
6. **Export at Resolution**: Support high-res output
