cannon.js\n\n### Lightweight 3D physics for the web\nInspired by [three.js](https://github.com/mrdoob/three.js) and [ammo.js](https://github.com/kripken/ammo.js), and driven by the fact that the web lacks a physics engine, here comes cannon.js.\nThe rigid body physics engine includes simple collision detection, various body shapes, contacts, friction and constraints.\n\n[Demos](http://schteppe.github.com/cannon.js) - [Documentation](http://schteppe.github.com/cannon.js/docs) - [Rendering hints](https://github.com/schteppe/cannon.js/tree/master/examples) - [NPM package](https://npmjs.org/package/cannon) - [CDN](https://cdnjs.com/libraries/cannon.js)\n\n### Browser install\n\nJust include [cannon.js](https://github.com/schteppe/cannon.js/releases/download/v0.6.2/cannon.js) or [cannon.min.js](https://github.com/schteppe/cannon.js/releases/download/v0.6.2/cannon.min.js) in your html and you\'re done:\n\n```html\n<script src="cannon.min.js"></script>\n```\n\n### Node.js install\n\nInstall the cannon package via NPM:\n\n```bash\nnpm install --save cannon\n```\n\nAlternatively, point to the Github repo directly to get the very latest version:\n\n```bash\nnpm install --save schteppe/cannon.js\n```\n\n### Example\n\nThe sample code below creates a sphere on a plane, steps the simulation, and prints the sphere simulation to the console. Note that Cannon.js uses [SI units](http://en.wikipedia.org/wiki/International_System_of_Units) (metre, kilogram, second, etc.).\n\n```javascript\n// Setup our world\nvar world = new CANNON.World();\nworld.gravity.set(0, 0, -9.82); // m/s²\n\n// Create a sphere\nvar radius = 1; // m\nvar sphereBody = new CANNON.Body({\n   mass: 5, // kg\n   position: new CANNON.Vec3(0, 0, 10), // m\n   shape: new CANNON.Sphere(radius)\n});\nworld.addBody(sphereBody);\n\n// Create a plane\nvar groundBody = new CANNON.Body({\n    mass: 0 // mass == 0 makes the body static\n});\nvar groundShape = new CANNON.Plane();\ngroundBody.addShape(groundShape);\nworld.addBody(groundBody);\n\nvar fixedTimeStep = 1.0 / 60.0; // seconds\nvar maxSubSteps = 3;\n\n// Start the simulation loop\nvar lastTime;\n(function simloop(time){\n  requestAnimationFrame(simloop);\n  if(lastTime !== undefined){\n     var dt = (time - lastTime) / 1000;\n     world.step(fixedTimeStep, dt, maxSubSteps);\n  }\n  console.log("Sphere z position: " + sphereBody.position.z);\n  lastTime = time;\n})();\n```\n\nIf you want to know how to use cannon.js with a rendering engine, for example Three.js, see the [Examples](examples).\n\n### Features\n* Rigid body dynamics\n* Discrete collision detection\n* Contacts, friction and restitution\n* Constraints\n   * PointToPoint (a.k.a. ball/socket joint)\n   * Distance\n   * Hinge (with optional motor)\n   * Lock\n   * ConeTwist\n* Gauss-Seidel constraint solver and an island split algorithm\n* Collision filters\n* Body sleeping\n* Experimental SPH / fluid support\n* Various shapes and collision algorithms (see table below)\n\n|             | [Sphere](http://schteppe.github.io/cannon.js/docs/classes/Sphere.html) | [Plane](http://schteppe.github.io/cannon.js/docs/classes/Plane.html) | [Box](http://schteppe.github.io/cannon.js/docs/classes/Box.html) | [Convex](http://schteppe.github.io/cannon.js/docs/classes/ConvexPolyhedron.html) | [Particle](http://schteppe.github.io/cannon.js/docs/classes/Particle.html) | [Heightfield](http://schteppe.github.io/cannon.js/docs/classes/Heightfield.html) | [Trimesh](http://schteppe.github.io/cannon.js/docs/classes/Trimesh.html) |\n| :-----------|:------:|:-----:|:---:|:------:|:--------:|:-----------:|:-------:|\n| Sphere      | Yes    | Yes   | Yes | Yes    | Yes      | Yes         | Yes     |\n| Plane       | -      | -     | Yes | Yes    | Yes      | -           | Yes     |\n| Box         | -      | -     | Yes | Yes    | Yes      | Yes         | (todo)  |\n| Cylinder    | -      | -     | Yes | Yes    | Yes      | Yes         | (todo)  |\n| Convex      | -      | -     | -   | Yes    | Yes      | Yes         | (todo)  |\n| Particle    | -      | -     | -   | -      | -        | (todo)      | (todo)  |\n| Heightfield | -      | -     | -   | -      | -        | -           | (todo)  |\n| Trimesh     | -      | -     | -   | -      | -        | -           | -       |\n\n### Todo\nThe simpler todos are marked with ```@todo``` in the code.
