Babylon.js

• We recommend using the Core ES6-supported version;

Getting started? Play directly with the Babylon.js API using our playground. It also contains a lot of samples to learn how to use it.

Any questions? Here is our official forum.

npm

BabylonJS and its modules are published on npm with full typing support. To install, use:

npm install babylonjs --save

This will allow you to import BabylonJS entirely using:

import * as BABYLON from 'babylonjs';

or individual classes using:

import { Scene, Engine } from 'babylonjs';

If using TypeScript, don't forget to add 'babylonjs' to 'types' in tsconfig.json:

    ...
    "types": [
        "babylonjs",
        "anotherAwesomeDependency"
    ],
    ...

To add a module, install the respective package. A list of extra packages and their installation instructions can be found on the babylonjs user on npm.

Usage

See Getting Started:

// Get the canvas DOM element
var canvas = document.getElementById('renderCanvas');
// Load the 3D engine
var engine = new BABYLON.Engine(canvas, true, {preserveDrawingBuffer: true, stencil: true});
// CreateScene function that creates and return the scene
var createScene = function(){
    // Create a basic BJS Scene object
    var scene = new BABYLON.Scene(engine);
    // Create a FreeCamera, and set its position to {x: 0, y: 5, z: -10}
    var camera = new BABYLON.FreeCamera('camera1', new BABYLON.Vector3(0, 5, -10), scene);
    // Target the camera to scene origin
    camera.setTarget(BABYLON.Vector3.Zero());
    // Attach the camera to the canvas
    camera.attachControl(canvas, false);
    // Create a basic light, aiming 0, 1, 0 - meaning, to the sky
    var light = new BABYLON.HemisphericLight('light1', new BABYLON.Vector3(0, 1, 0), scene);
    // Create a built-in "sphere" shape; its constructor takes 6 params: name, segment, diameter, scene, updatable, sideOrientation
    var sphere = BABYLON.Mesh.CreateSphere('sphere1', 16, 2, scene, false, BABYLON.Mesh.FRONTSIDE);
    // Move the sphere upward 1/2 of its height
    sphere.position.y = 1;
    // Create a built-in "ground" shape; its constructor takes 6 params : name, width, height, subdivision, scene, updatable
    var ground = BABYLON.Mesh.CreateGround('ground1', 6, 6, 2, scene, false);
    // Return the created scene
    return scene;
}
// call the createScene function
var scene = createScene();
// run the render loop
engine.runRenderLoop(function(){
    scene.render();
});
// the canvas/window resize event handler
window.addEventListener('resize', function(){
    engine.resize();
});
