The Atlas – I Built a 3D Universe Simulation with Python and Three.js [Entertainment]
5 points, 4 comments
A procedural 3D universe simulator generating 1 sextillion galaxies from a mathematical seed, running entirely in the browser with real physics and deterministic behavior.
- Generates 10²¹ galaxies deterministically from SHA-256 hashed seeds using the golden ratio
- Treats time as a coordinate in a 4D structure, allowing any moment to be computed on demand
- Applies real physics (Kepler’s laws, tidal locking, Roche limits, hydrostatic relaxation)
- Includes 26+ planet types, fictional elements, evolving moons, and rare life forms
- Features resource mining, spaceship progression, and shared-seed universes
- Backend: Python/Flask with Hypercorn; frontend: React + Three.js
- MIT-licensed "vite-fusion" plugin for real-time generation with no storage needed
