# Interactive 3D platform with native control

**AI-Powered · World**

A web platform where you can control digital objects with hand movements. Created entirely with AI tools in one day.

**Technologies:** Three.js, Cannon.js, MediaPipe · **Timeline:** 1 day

## Interactive Demo

Pinch your index finger and thumb together to grab cubes and move them around the virtual space. Watch them fall and interact with real physics.

Video demo: [Hand Tracking Cube Game](https://vimeo.com/1146899789)

## What AI Enables

- Rapid prototyping—complex interactive experiences in hours instead of weeks
- Physics simulation with realistic object behavior
- Gesture recognition with pinch-to-grab controls
- Immersive 3D scenes with lighting and shadows

## How It Works

**MediaPipe Hands** tracks 21 hand landmarks in real-time. Distance between thumb and index finger determines pinch-to-grab.

**Cannon.js** provides physics simulation with realistic weight, gravity, and collision detection.

**Three.js** renders the 3D scene with dynamic lighting, shadows, and hand skeleton visualization.

## Technologies

Three.js · Cannon.js · MediaPipe Hands · WebGL · AI-assisted code generation

## The Future of Interaction

AI tools enable rapid creation of complex interactive experiences that would traditionally require a specialized team—prototyped in a single day.
