Cyclone Javascript Physics Engine

A manual port of the Cyclone Physics Engine (http://procyclone.com/) from C++ to JavaScript

Usage:

// initial setup
elation.physics.system.start();

var smallball = new elation.physics.rigidbody({ 
  mass: 1, 
  position: new THREE.Vector3(0, 0, 1),
  velocity: new THREE.Vector3(0, 0, -1) 
});
smallball.setCollider("sphere", 2);
elation.events.add(smallball, "collide", function() { console.log('small boing!'); });
elation.physics.system.add(smallball);

var bigball = new elation.physics.rigidbody({
  mass: 10, 
  position: new THREE.Vector3(1, 0, 0),
  velocity: new THREE.Vector3(-1, 0, 0) 
});
bigball.setCollider("sphere", 5);
elation.events.add(bigball, "collide", function() { console.log('big boing!'); });
elation.physics.system.add(bigball);

// render loop
var lasttime = Date.now();
requestAnimationFrame(stepfunc);

function stepfunc(t) {
  elation.physics.system.iterate(t - lasttime);
  renderer.render();
  lasttime = t;
  requestAnimationFrame(stepfunc);
});
