Antikyth

Bullet Physics 3 server for node.js. Designed for multiple realtime clients.

Runs at native C++ speed in a dedicated process, so this is probably the fastest physics you can get for node. This is not an emscripten build, and does not run in the browser. If that's what you want, you're probably looking for ammo.js.

This also does not include any rendering, only the backend number crunching. If you want rendering, you probably want to plug this into a THREE.js frontend.

Install

npm install antikyth

Example

const Antikyth = require('.');

// initialize new physics engine

const engine = new Antikyth();

// initialize new world

const world = new Antikyth.World();
engine.add(world);

// add some bodies

const floor = new Antikyth.Plane({
  position: [0, 0, 0],
  dimensions: [0, 1, 0],
  mass: 0,
});
world.add(floor);

const box = new Antikyth.Box({
  position: [0, 2, 0],
  rotation: [Math.PI / 8, 0, 0, 1],
  dimensions: [1, 1, 1],
  mass: 1,
});
world.add(box);

// request engine updates at 60 FPS

setInterval(() => {
  engine.requestUpdate();
}, 1000 / 60);

// log updates to console

box.on('update', ({position: [px, py, pz], rotation: [rx, ry, rz, rw]}) => {
  console.log('box', px, py, pz);
});

// start running

engine.start();
