Interactive 3D Galaxy Orb — WebGL & Three.js Animation with Source Code
The Interactive Galaxy Orb is a futuristic 3D component that brings the beauty of a swirling galaxy to your browser. Built using WebGL and Three.js, it combines high-performance particle systems with interactive mouse tracking and an explosive click reaction.
How It Works
This animation uses Three.js to manage a 3D scene. A buffer geometry stores 8,000 individual particles, each colored and positioned to form a spiral galaxy shape. A custom material with additive blending creates the glowing “neon” look. JavaScript logic handle mouse movement to rotate the entire system and triggers an “explosion” on click, where particles fly outwards before gradually returning to their original orbits.
Key Features
- 8,000+ Particles: High-performance rendering for a dense, vibrant galaxy look.
- Interactive Rotation: Moves and tilts based on the user’s cursor position.
- Explosive Physics: Particles react to clicks with a burst of outward momentum.
- Responsive WebGL: Automatically adjusts to window resizing for a perfect fullscreen or container fit.
Frequently Asked Questions
Do I need to install Three.js?
For this specific implementation, Three.js is loaded via a CDN (Cloudflare) to keep it self-contained. You don’t need to add it to your project’s dependencies.
Can I change the galaxy colors?
Yes! In the JavaScript code, search for colorPalette. You can update the hex values to match your brand’s color scheme.
Is this mobile-friendly?
Yes, but WebGL performance varies by device. On older smartphones, you may want to reduce the PARTICLE_COUNT for smoother frames.
