SpeedDemon

A 10,000-particle browser physics stress test powered by Rust and WebAssembly.

Technology stack

Rust / WASM / Macroquad / Spatial Grid

SpeedDemon combines Verlet integration with spatial grid partitioning to resolve thousands of particle collisions in real time.

Interactive controls adjust particle volume, expose the collision grid, pause the simulation, and apply mouse-driven repulsion forces.
