🎮 Gaming Framework - DONE ✅

Status: Complete and ready for review
PR: #60
Branch: feature/gaming-framework-integration
Date: March 1, 2026

What Was Accomplished

This implementation adds gaming framework capabilities to Rendervid, enabling AI agents to create game-style marketing videos with physics, particles, animations, and behaviors.

Core Implementation

  1. Physics Package (@rendervid/physics)

  3. Keyframe Animations (packages/renderer-browser/src/animation/)

    • Property-based keyframes
    • Linear interpolation
    • Position, rotation, scale animations
    • Frame-accurate timing

  4. Behavior Presets (packages/renderer-browser/src/behaviors/)

Type System

All features are fully typed in packages/core/src/types/three.ts:

interface ThreeMeshConfig {
  rigidBody?: RigidBodyConfig;
  collider?: ColliderConfig;
  animations?: AnimationConfig[];
  behaviors?: BehaviorConfig[];
}

interface ThreeLayerProps {
  physics?: PhysicsConfig;
  particles?: ParticleEmitterConfig[];
  postProcessing?: PostProcessingConfig;
}

JSON Configuration

Example template using all features:

{
  "type": "three",
  "props": {
    "physics": {
      "enabled": true,
      "gravity": [0, -9.81, 0]
    },
    "meshes": [{
      "geometry": { "type": "sphere", "radius": 0.5 },
      "rigidBody": { "type": "dynamic", "mass": 1 },
