Oimo Physics

Oimo.js is a JavaScript 3D rigid body physics engine optimized for web and mobile. It simulates gravity, collisions, friction, restitution, and constraints (joints). Developers typically pair it with a rendering engine like Three.js or Babylon.js: Oimo calculates physics (where objects should be), Three.js draws them. Key features: broadphase collision detection (octree), narrowphase (sphere, box, capsule primitives), constraint solver (iterative), raycasting, and compound shapes.
