Three JS Interactive Builder

Three.js Interactive Builder

Build production-ready Three.js visualizations with algorithmic art principles.

Core Architecture

Every project follows modular synthesis philosophy: components as oscillators, connections as patches.

Quick Start

1. Copy boilerplate from assets/threejs-boilerplate/
2. Initialize scene with preferred renderer settings
3. Add geometry generators from scripts/
4. Wire animation loops

Geometry Patterns

Sacred Geometry Primitives

Use scripts/sacred_geometry.py to generate vertex data for:

• Flower of Life: Overlapping circles, customizable depth
• Metatron's Cube: 13-circle formation with connecting lines
• Sri Yantra: 9 interlocking triangles
• Seed of Life: 7-circle genesis pattern
• Vesica Piscis: Intersection geometry

Spiral Systems

For gravitational/golden spirals:

function goldenSpiral(loops, pointsPerLoop, scale) {
  const phi = (1 + Math.sqrt(5)) / 2;
  const points = [];
  for (let i = 0; i < loops * pointsPerLoop; i++) {
    const theta = i * 0.1;
    const r = scale * Math.pow(phi, theta / (2 * Math.PI));
    points.push(new THREE.Vector3(r * Math.cos(theta), r * Math.sin(theta), 0));
  }
  return points;
}

Lane Systems

For multi-lane visualizations (soul lanes, data streams):

function createLaneSystem(laneCount, radius, spacing) {
  const lanes = [];
  for (let i = 0; i < laneCount; i++) {
    lanes.push({ radius: radius + (i * spacing), objects: [], speed: 1 / (i + 1) });
  }
  return lanes;
}

Animation Patterns

Temporal Perspective

For simultaneous time visualization (all moments visible at once):

class TemporalController {
  constructor(timeline) {
    this.moments = timeline;
    this.currentView = 'linear';
  }
  setSimultaneous() {
    this.moments.forEach((m, i) => {
      m.mesh.visible = true;
      m.mesh.material.opacity = 0.3 + (0.7 * (i / this.moments.length));
    });
  }
}

Breath-Based Animation

Organic pulsing using sine waves:

function breathe(object, speed = 1, amplitude = 0.1) {
  const scale = 1 + Math.sin(Date.now() * 0.001 * speed) * amplitude;
  object.scale.setScalar(scale);
}

Shader Patterns

See references/glsl-patterns.md for glow effects, noise functions, color gradients, and symbol rendering.

Project Types

Algorithmic Art: Define rules → Generate geometry → Add temporal dimension → Apply aesthetic layer

Interactive Visualization: OrbitControls → Raycasting → UI overlay → State management

Narrative Experience: Story beats as states → Transitions → Audio cues → Navigation

Performance

• BufferGeometry for >1000 vertices
• InstancedMesh for repeated objects
• LOD for complex scenes
• Merge geometries to reduce draw calls
