OimoPhysics 1.2.5

A lightweight 3D physics engine.

License: MIT npm version

Demos

  • Press E or Q to change demos
  • Click or tap texts on the left to control

Platforms

  • Written in Haxe
  • Exported as JavaScript (see bin/js/)
    • Public classes and methods are exposed through window.OIMO.
    • e.g. new OIMO.Vec3(1, 2, 3) to create an instance of Vec3 class.
  • Exported as JavaScript (module) with TypeScript Declaration (see package.json and bin/js_modules)

Features

  • Rigid body with motion types
    • Dynamic
    • Static
    • Kinematic
  • Fast collision detection with bounding volume hierarchy (BVH)
  • Contacts with friction and restitution
  • Collision geometries
    • Sphere
    • Box
    • Cylinder
    • Cone
    • Capsule
    • Convex hull
  • Joints with springs, limits and motors
    • Spherical (a.k.a. ball and socket, point to point)
    • Revolute (a.k.a. hinge)
    • Cylindrical
    • Prismatic (a.k.a. slider)
    • Universal
    • Ragdoll (a.k.a. cone twist, character)
    • Generic (a.k.a. 6-DoF joint)
  • Breakable joints
  • Constraint solvers
    • Direct block MLCP solver
    • Projected Gauss-Seidel solver
  • Sleepings with island splittings
  • Rotation limits
  • Collision event callbacks
  • Collision filterings
  • Collision queries
    • AABB query
    • Ray casting
    • Convex casting

Compilations

Haxe 4.3.4 or later is required.

  • Use build-js.hxml to compile for JavaScript library.
  • Use build-js-demos.hxml to compile JavaScript demos.
  • Use build-doc.hxml to generate API documentation. dox is required.
  • Use build-js-ts.hxml to compile for JavaScript (modules) library with TypeScript declarations. Requires hxtsdgen library. Check comments in that file.
