ARTICHAR demonstrates real-time physics-based character animation running entirely in your browser. Unlike traditional keyframe animation, characters are simulated as physical bodies with joints, muscles, and contact forces — controlled by neural network policies that generate natural, responsive motion.

How It Works

• Physics simulation runs at 200Hz using MuJoCo (Multi-Joint dynamics with Contact)
• Neural networks output joint torques to produce lifelike movements
• Characters respond dynamically to perturbations and terrain
• No pre-recorded animations — all motion emerges from physics

Technology Stack

• MuJoCo WASM — Physics engine by Google DeepMind
• Three.js — WebGL 3D rendering
• ONNX Runtime — Neural network inference
• WebXR — VR headset support

Controls

• Drag to orbit the camera around the scene
• Scroll/pinch to zoom in and out
• Tap animations at the bottom to switch motions
• Use the side buttons to reset view or physics

VR Experience

This demo fully supports Virtual Reality! For the best experience, open this page directly in your VR headset's browser:

• Meta Quest — Use the Meta Quest Browser
• Apple Vision Pro — Use Safari
• PC VR — Use Chrome/Edge with SteamVR or Oculus Link

Once in VR, you'll have hand controllers to interact with the scene and select animations from a floating 3D panel.
