Oimo.js is a lightweight 3d physics engine for JavaScript.
It's a full javascript conversion of OimoPhysics
Originally created by Saharan for actionscript 3.0.

Download the minified library and include it in your HTML.
Alternatively, use Node and install the package: npm install oimo
<script src="js/oimo.min.js"></script>
Create physics world:
world = new OIMO.World({ timestep: 1/60, iterations: 8, broadphase: 2, // 1 brute force, 2 sweep and prune, 3 volume tree worldscale: 1, // scale full world random: true, // randomize sample info: false, // calculate statistic or not gravity: [0,-9.8,0] });
Add physics object or joint
var body = world.add({ type:'sphere', // type of shape : sphere, box, cylinder size:[1,1,1], // size of shape pos:[0,0,0], // start position in degree rot:[0,0,90], // start rotation in degree move:true, // dynamic or statique density: 1, friction: 0.2, restitution: 0.2, belongsTo: 1, // The bits of the collision groups to which the shape belongs. collidesWith: 0xffffffff // The bits of the collision groups with which the shape collides. }); var body = world.add({ type:'jointHinge', // type of joint : jointDistance, jointHinge, jointPrisme, jointSlide, jointWheel body1: "b1", // name or id of attach rigidbody body2: "b1" // name or id of attach rigidbody }); // update world world.step(); // and copy position and rotation to three mesh myMesh.position.copy( body.getPosition() ); myMesh.quaternion.copy( body.getQuaternion() );
Oimo Physics uses international system units: 0.1 to 10 meters max for dynamic body.
In basic demo with THREE, I scaled all by 100 so objects are between 10 to 1000 in THREE units.
/!\ Shape name change in last version
SphereShape to Sphere, BoxShape to Box, CylinderShape to Cylinder
Is time to switch ES6 worker version with the last OimoPhysics 1.2.2 :)
