cannon.js is a lightweight 3D rigid body physics engine written in JavaScript for the web. It provides collision detection, friction, restitution, constraints, and a Gauss-Seidel constraint solver, usable in browsers or Node.js.

Use cases

• add physics to a three.js 3D scene
• simulate falling spheres and rigid bodies in the browser
• build a simple 3D game with gravity and collisions
• create hinge or ball-socket joints between bodies
• run a physics simulation headlessly in Node.js

When to choose

• you need a small, pure-JavaScript physics engine with no native dependencies
• you are building browser-based 3D games or visualizations with three.js
• you need basic rigid body dynamics, constraints, and collision detection

When to avoid

• you need high-performance or highly accurate physics for large scenes (consider ammo.js or Rapier)
• you need soft body or advanced fluid simulation
• you need a project under very active development
