Three.js Interactive 3D Galaxy Generator

This interactive 3D galaxy generator allows users to create and manipulate beautiful spiral galaxies in real-time using Three.js. The generator creates thousands of particles arranged in spiral arms with a central core, simulating the appearance of distant galaxies.

Users can control four key parameters: particle count (from 1,000 to 20,000 stars), particle size, rotation speed, and galaxy spread (how far the arms extend). The color gradient automatically adjusts from cooler blues in the center to warmer yellows and whites in the outer arms, mimicking real galaxy color distributions.

The interface includes real-time controls with visual feedback, mouse-based camera rotation, and zoom controls. The FPS counter helps users monitor performance as they adjust particle counts. Each parameter change immediately regenerates the galaxy geometry, allowing for endless exploration of different galactic formations.

This project demonstrates core Three.js concepts including BufferGeometry for efficient particle systems, vertex coloring, camera controls, and real-time parameter updates. The responsive design ensures the generator works well on both desktop and mobile devices.
