Babylon.js

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.

CDN

⚠️ WARNING: The CDN should not be used in production environments. The purpose of our CDN is to serve Babylon packages to users learning how to use the platform or running small experiments. Once you've built an application and are ready to share it with the world at large, you should serve all packages from your own CDN.

• https://cdn.babylonjs.com/babylon.js
• https://cdn.babylonjs.com/babylon.max.js

For the preview release, use the following URLs:

• https://preview.babylonjs.com/babylon.js
• https://preview.babylonjs.com/babylon.max.js

npm

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

npm install babylonjs --save

alternatively, you can now rely on our ES6 packages. Using the ES6 version will allow tree shaking among other bundling benefits.

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 using the SphereBuilder
    var sphere = BABYLON.MeshBuilder.CreateSphere('sphere1', {segments: 16, diameter: 2, sideOrientation: BABYLON.Mesh.FRONTSIDE}, scene);
    // Move the sphere upward 1/2 of its height
    sphere.position.y = 1;
    // Create a built-in "ground" shape;
    var ground = BABYLON.MeshBuilder.CreateGround("ground1", { width: 6, height: 6, subdivisions: 2, updatable: false }, scene);
    // 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();
});

Contributing

Building and developing this repository requires Node.js 22.22.2 or newer within the Node 22 line, or Node.js 24.15.0 or newer within the Node 24 line, and npm 11.18.0 or newer. These are development-tool requirements; they do not change the runtime requirements of the published Babylon.js libraries.

If you want to contribute, please read our contribution guidelines first.
