Babylon.js

We recommend using the ES6 package @babylonjs/core for new projects. This UMD package is provided for compatibility.

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.

npm

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

text

npm install babylonjs

This will allow you to import Babylon.js entirely using:

javascript

import * as BABYLON from "babylonjs";

or individual classes using:

javascript

import { Scene, Engine } from "babylonjs";

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

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:

javascript

const canvas = document.getElementById("renderCanvas");
const engine = new BABYLON.Engine(canvas, true, { preserveDrawingBuffer: true, stencil: true });

const createScene = () => {
    const scene = new BABYLON.Scene(engine);
    const camera = new BABYLON.FreeCamera("camera1", new BABYLON.Vector3(0, 5, -10), scene);
    camera.setTarget(BABYLON.Vector3.Zero());
    camera.attachControl(canvas, false);

    const light = new BABYLON.HemisphericLight("light1", new BABYLON.Vector3(0, 1, 0), scene);

    const sphere = BABYLON.MeshBuilder.CreateSphere("sphere1", { segments: 16, diameter: 2 }, scene);
    sphere.position.y = 1;

    BABYLON.MeshBuilder.CreateGround("ground1", { width: 6, height: 6, subdivisions: 2 }, scene);

    return scene;
};

const scene = createScene();
engine.runRenderLoop(() => {
    scene.render();
});
window.addEventListener("resize", () => {
    engine.resize();
});
