一览

Oimo is a lightweight 3D physics engine for JavaScript, optimized for web browsers. It handles rigid body dynamics, collision detection, constraints (joints), and raycasting. Used in game engines, AR experiences, and interactive 3D visualizations. Learning curve: 4-6 weeks for game developers, 8+ weeks for simulation specialists. Niche skill: 2k-5k engineers worldwide. Senior practitioners earn 20-30% premium for shipping complex simulations.

什么是 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.

❓ 常见问题

Why use Oimo instead of Cannon.js or Ammo.js?

Oimo is lighter (smaller bundle) and faster for simple scenes. Cannon is more feature-rich but heavier. Ammo is port of Bullet (industry standard). Oimo = sweet spot for web AR, casual games. Cannon = competitive games. Ammo = AAA simulation.

Can Oimo run on mobile/AR?

Yes. Oimo was built for mobile performance. Average 60 FPS on iPhone 12+ for scenes with 100-200 bodies. AR.js + Three.js + Oimo common stack.

How do I sync physics with 3D graphics?

Loop: update physics world, read body positions/rotations, update Three.js mesh positions. Sync every frame. Decoupling = jitter.

What types of joints does Oimo support?

Ball joint, hinge, prismatic, fixed. No soft constraints (springs). For springs, code impulse-based solver or use Cannon.

Can I import a complex mesh (concave collision) into Oimo?

Only convex hulls natively. Concave = decompose into convex pieces. Tools exist (Convex Decomposition) but add complexity. Start with simple shapes.
