Browser-based interactive 3D Three-Body problem simulator

In plain words

This browser-based simulator visualizes the three-body problem in interactive 3D, allowing users to explore periodic orbital solutions including the classic Figure-8 and newly discovered configurations from Li and Liao's database of over 10,000 orbits. Built with Three.js, it offers full 3D camera controls, body-following mode, force and velocity vector visualization, and timeline scrubbing to examine complete orbital periods. The tool is designed for anyone interested in celestial mechanics, physics education, or mathematical visualization.

In the maker’s words, at launch

Features include: - Several preset periodic orbits: the classic Figure-8, plus newly discovered 3D solutions from Li and Liao's recent database of 10,000+ orbits (https://arxiv.org/html/2508.08568v1) - Full 3D camera controls (rotate/pan/zoom) with body-following mode - Force and velocity vector visualization - Timeline scrubbing to explore the full orbital period The 3D presets are particularly interesting. Try "O₂(1.2)" or "Piano O₆(0.6)" from the Load Presets menu to see configurations where bodies weave in and out of the orbital plane. Most browser simulators I've seen have been 2D. Built with Three.js. Open to suggestions for additional presets or features!
