kripken/ammo.js
Ammo.js
ammo.js is a JavaScript port of the Bullet physics engine, compiled via Emscripten to provide a high-performance physics library for the browser. It functions as a 3D rigid body engine and an Emscripten compiled library that enables complex physical computations using WebAssembly and JavaScript.
The project provides specialized simulation capabilities for soft body physics, modeling the deformation of flexible materials like cloth and rubber, and a vehicle dynamics engine for calculating the mechanics of wheeled vehicles.
The simulation surface also covers rigid body dynamics for non-deformable solid objects and heightmap terrain generation for creating 3D landscapes that drive physical interactions.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
