Oimo.js is a lightweight 3D physics engine written in pure JavaScript, a full conversion of the ActionScript OimoPhysics library. It provides rigid body simulation with shapes, joints, collision groups, and broadphase options for browser and Node.js applications.

Use cases

• add 3d physics to a three.js scene
• simulate rigid bodies and collisions in the browser
• build ragdoll or vehicle physics for a web game
• run physics simulation in a web worker
• create hinge and slider joints between bodies

When to choose

• you need a small, dependency-free 3d physics engine for javascript
• you want simple rigid body and joint simulation in the browser
• you are building a lightweight web game or interactive demo

When to avoid

• you need actively maintained software with recent releases
• you require advanced features like soft bodies or GPU acceleration
• you need a battle-tested engine like cannon-es, ammo.js, or rapier for production
