Galaxy

A real-time 3D galaxy with 300,000 particles, 8 spiral arms, and custom GLSL shaders.

// about

An interactive 3D galaxy visualisation built with Three.js. 300,000 point particles are procedurally placed across 8 spiral arms using a custom GLSL vertex shader, with a fragment shader that creates a glowing orb effect via distance-based brightness falloff and additive blending. The scene animates in real time via a time uniform. A lil-gui panel exposes all parameters for live tweaking.
