// ============================================================================
|
||||
// 1. PARAMETER ORGANIZATION
|
||||
// ============================================================================
|
||||
// Keep all tunable parameters in one object
|
||||
// This makes it easy to:
|
||||
// - Connect to UI controls
|
||||
// - Reset to defaults
|
||||
// - Serialize/save configurations
|
||||
|
||||
let params = {
|
||||
// Define parameters that match YOUR algorithm
|
||||
// Examples (customize for your art):
|
||||
// - Counts: how many elements (particles, circles, branches, etc.)
|
||||
// - Scales: size, speed, spacing
|
||||
// - Probabilities: likelihood of events
|
||||
// - Angles: rotation, direction
|
||||
// - Colors: palette arrays
|
||||
|
||||
seed: 12345,
|
||||
// define colorPalette as an array -- choose whatever colors you'd like ['#d97757', '#6a9bcc', '#788c5d', '#b0aea5']
|
||||
// Add YOUR parameters here based on your algorithm
|
||||
};
|
||||
|
||||
// ============================================================================
|
||||
// 2. SEEDED RANDOMNESS (Critical for reproducibility)
|
||||
// ============================================================================
|
||||
// ALWAYS use seeded random for Art Blocks-style reproducible output
|
||||
|
||||
function initializeSeed(seed) {
|
||||
randomSeed(seed);
|
||||
noiseSeed(seed);
|
||||
// Now all random() and noise() calls will be deterministic
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// 3. P5.JS LIFECYCLE
|
||||
// ============================================================================
|
||||
|
||||
function setup() {
|
||||
createCanvas(800, 800);
|
||||
|
||||
// Initialize seed first
|
||||
initializeSeed(params.seed);
|
||||
|
||||
// Set up your generative system
|
||||
// This is where you initialize:
|
||||
// - Arrays of objects
|
||||
// - Grid structures
|
||||
// - Initial positions
|
||||
// - Starting states
|
||||
|
||||
// For static art: call noLoop() at the end of setup
|
||||
// For animated art: let draw() keep running
|
||||
}
|
||||
|
||||
function draw() {
|
||||
// Option 1: Static generation (runs once, then stops)
|
||||
// - Generate everything in setup()
|
||||
// - Call noLoop() in setup()
|
||||
// - draw() doesn't do much or can be empty
|
||||
|
||||
// Option 2: Animated generation (continuous)
|
||||
// - Update your system each frame
|
||||
// - Common patterns: particle movement, growth, evolution
|
||||
// - Can optionally call noLoop() after N frames
|
||||
|
||||
// Option 3: User-triggered regeneration
|
||||
// - Use noLoop() by default
|
||||
// - Call redraw() when parameters change
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// 4. CLASS STRUCTURE (When you need objects)
|
||||
// ============================================================================
|
||||
// Use classes when your algorithm involves multiple entities
|
||||
// Examples: particles, agents, cells, nodes, etc.
|
||||
|
||||
class Entity {
|
||||
constructor() {
|
||||
// Initialize entity properties
|
||||
// Use random() here - it will be seeded
|
||||
}
|
||||
|
||||
update() {
|
||||
// Update entity state
|
||||
// This might involve:
|
||||
// - Physics calculations
|
||||
// - Behavioral rules
|
||||
// - Interactions with neighbors
|
||||
}
|
||||
|
||||
display() {
|
||||
// Render the entity
|
||||
// Keep rendering logic separate from update logic
|
||||
}
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// 5. PERFORMANCE CONSIDERATIONS
|
||||
// ============================================================================
|
||||
|
||||
// For large numbers of elements:
|
||||
// - Pre-calculate what you can
|
||||
// - Use simple collision detection (spatial hashing if needed)
|
||||
// - Limit expensive operations (sqrt, trig) when possible
|
||||
// - Consider using p5 vectors efficiently
|
||||
|
||||
// For smooth animation:
|
||||
// - Aim for 60fps
|
||||
// - Profile if things are slow
|
||||
// - Consider reducing particle counts or simplifying calculations
|
||||
|
||||
// ============================================================================
|
||||
// 6. UTILITY FUNCTIONS
|
||||
// ============================================================================
|
||||
|
||||
// Color utilities
|
||||
function hexToRgb(hex) {
|
||||
const result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex);
|
||||
return result ? {
|
||||
r: parseInt(result[1], 16),
|
||||
g: parseInt(result[2], 16),
|
||||
b: parseInt(result[3], 16)
|
||||
} : null;
|
||||
}
|
||||
|
||||
function colorFromPalette(index) {
|
||||
return params.colorPalette[index % params.colorPalette.length];
|
||||
}
|
||||
|
||||
// Mapping and easing
|
||||
function mapRange(value, inMin, inMax, outMin, outMax) {
|
||||
return outMin + (outMax - outMin) * ((value - inMin) / (inMax - inMin));
|
||||
}
|
||||
|
||||
function easeInOutCubic(t) {
|
||||
return t < 0.5 ? 4 * t * t * t : 1 - Math.pow(-2 * t + 2, 3) / 2;
|
||||
}
|
||||
|
||||
// Constrain to bounds
|
||||
function wrapAround(value, max) {
|
||||
if (value < 0) return max;
|
||||
if (value > max) return 0;
|
||||
return value;
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// 7. PARAMETER UPDATES (Connect to UI)
|
||||
// ============================================================================
|
||||
|
||||
function updateParameter(paramName, value) {
|
||||
params[paramName] = value;
|
||||
// Decide if you need to regenerate or just update
|
||||
// Some params can update in real-time, others need full regeneration
|
||||
}
|
||||
|
||||
function regenerate() {
|
||||
// Reinitialize your generative system
|
||||
// Useful when parameters change significantly
|
||||
initializeSeed(params.seed);
|
||||
// Then regenerate your system
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// 8. COMMON P5.JS PATTERNS
|
||||
// ============================================================================
|
||||
|
||||
// Drawing with transparency for trails/fading
|
||||
function fadeBackground(opacity) {
|
||||
fill(250, 249, 245, opacity); // Anthropic light with alpha
|
||||
noStroke();
|
||||
rect(0, 0, width, height);
|
||||
}
|
||||
|
||||
// Using noise for organic variation
|
||||
function getNoiseValue(x, y, scale = 0.01) {
|
||||
return noise(x * scale, y * scale);
|
||||
}
|
||||
|
||||
// Creating vectors from angles
|
||||
function vectorFromAngle(angle, magnitude = 1) {
|
||||
return createVector(cos(angle), sin(angle)).mult(magnitude);
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// 9. EXPORT FUNCTIONS
|
||||
// ============================================================================
|
||||
|
||||
function exportImage() {
|
||||
saveCanvas('generative-art-' + params.seed, 'png');
|
||||
}
|
||||
|
||||
// ============================================================================
|
||||
// REMEMBER
|
||||
// ============================================================================
|
||||
//
|
||||
// These are TOOLS and PRINCIPLES, not a recipe.
|
||||
// Your algorithmic philosophy should guide WHAT you create.
|
||||
// This structure helps you create it WELL.
|
||||
//
|
||||
// Focus on:
|
||||
// - Clean, readable code
|
||||
// - Parameterized for exploration
|
||||
// - Seeded for reproducibility
|
||||
// - Performant execution
|
||||
//
|
||||
// The art itself is entirely up to you!
|
||||

<!--
|

THIS IS A TEMPLATE THAT SHOULD BE USED EVERY TIME AND MODIFIED.
|
||||
WHAT TO KEEP:
|
||||
✓ Overall structure (header, sidebar, main content)
|
||||
✓ Anthropic branding (colors, fonts, layout)
|
||||
✓ Seed navigation section (always include this)
|
||||
✓ Self-contained artifact (everything inline)
|
||||
|
||||
WHAT TO CREATIVELY EDIT:
|
||||
✗ The p5.js algorithm (implement YOUR vision)
|
||||
✗ The parameters (define what YOUR art needs)
|
||||
✗ The UI controls (match YOUR parameters)
|
||||
|
||||
Let your philosophy guide the implementation.
|
||||
The world is your oyster - be creative!
