3D graphics on the web have become much more accessible thanks to modern libraries like Three.js. As a personal challenge, I decided to build an interactive 3D Rubik's Cube that runs entirely in the browser.
The objective wasn't just to render a cube, but to recreate the mechanics of a real Rubik's Cube with smooth animations, realistic rotations, and an intuitive interface.

🚀 Why This Project?
This project allowed me to explore several areas of modern web development:
- Real-time 3D rendering
- Matrix transformations
- Object hierarchy management
- Smooth animations
- Interactive controls
- Performance optimization
Building a Rubik's Cube is an excellent exercise because every move affects multiple pieces while preserving the cube's overall structure.
🛠️ Tech Stack
- Three.js
- Vite
- GSAP
- dat.GUI
✨ Features
- 🧩 Fully interactive 3D Rubik's Cube
- 🎮 Individual face rotations
- 🎥 Free camera rotation
- ⚡ Smooth animations with GSAP
- ⏱️ Integrated timer
- 🔢 Move counter
- 🎲 Random shuffle
- 🔄 Reset cube
- 📜 Move history
- 🎨 Responsive interface
🧠 Cube Architecture
The Rubik's Cube is composed of 27 smaller cubes (Cubies).
Each cubie is an independent Three.js Mesh positioned inside a virtual 3×3×3 grid.
Instead of modifying a single object, every rotation updates only the cubies belonging to the selected face.
This architecture closely reproduces the behavior of a physical Rubik's Cube.
🔄 Face Rotation Logic
When a player rotates a face, the application performs several steps:
- Identify the cubies belonging to the selected layer.
- Group them temporarily.
- Animate the rotation using GSAP.
- Update each cubie's position.
- Update each cubie's orientation.
- Remove the temporary group.
- Wait for the next move.
This keeps the cube perfectly synchronized after every animation.
🎨 Rendering with Three.js
Three.js handles the entire 3D scene, including:
- Perspective Camera
- Scene
- WebGL Renderer
- Lights
- Meshes
- Materials
- Camera Controls
Using hardware acceleration through WebGL allows the cube to remain fluid even during continuous rotations.
⚡ Smooth Animations
Every face rotation is animated with GSAP, providing fluid and natural movements.
The animation system also prevents overlapping rotations, ensuring that one move is completed before another begins.
This greatly improves the overall user experience.
🚧 Technical Challenges
Although the interface looks simple, implementing the mechanics required solving several interesting problems:
- Correctly identifying cubies on each face
- Preserving cube orientation after rotations
- Synchronizing animations with cube state
- Preventing simultaneous moves
- Updating positions without losing precision
- Maintaining smooth rendering performance
These challenges made the project much more interesting than a simple 3D rendering demo.
📚 What I Learned
This project helped me improve my knowledge of:
- Three.js
- WebGL rendering
- 3D transformations
- Rotation matrices
- Object hierarchy
- GSAP animations
- Interactive UI design
- Vite project architecture
Building interactive 3D applications is a great way to better understand graphics programming and object transformations.
💡 Future Improvements
Some ideas for future versions include:
- 🤖 Automatic solving algorithm
- 📖 Beginner solving tutorial
- 🎯 Scramble generator
- 💾 Save and restore cube state
- 🌙 Additional visual themes
- 📱 Improved mobile controls
- 🏆 Speedcubing statistics
- 🎵 Sound effects
🎉 Conclusion
Building this Rubik's Cube was an exciting challenge that combined mathematics, 3D graphics, animations, and front-end development.
Rather than relying on a game engine, the entire experience was built using Three.js, GSAP, and Vite, resulting in a lightweight and interactive web application.
If you're interested in Three.js, WebGL, or interactive 3D experiences on the web, I'd love to hear your feedback!
