A small, interactive double pendulum demo that separates a high-performance physics engine (written in Rust and compiled to WASM) from a responsive web UI (React + TypeScript), and PixiJS for high-performance canvas rendering.

Live demo · pendulum.notaroomba.dev

• High-performance physics core implemented in Rust and compiled to WebAssembly for accurate, real-time simulation
• Smooth, interactive Web UI built with React, PixiJS, and TypeScript
• Prebuilt WASM physics/pkg so you can run the demo without a local Rust toolchain
• Adjustable parameters (masses, lengths, gravity, initial angles) and simulation controls (start/stop/reset)
• Different implementations (RK4, Hamltonian, etc...)

• Presets and exportable snapshots for sharing interesting trajectories
• Plots and graphs for the simulation
• Game-ify it?

• Rust and wasm-bindgen for the physics engine
• React for the UI, TailwindCSS for the styling, and PixiJS for rendering
• Inspiration and examples from many open-source double pendulum visualizations
