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.

CDN

To look into our CDN bundled distribution, you can refer to the package babylonjs

npm

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

npm install @babylonjs/core --save

This will allow you to import BabylonJS entirely using:

import * as BABYLON from "@babylonjs/core/Legacy/legacy";

or individual classes to benefit from enhanced tree shaking using :

import { Scene } from "@babylonjs/core/scene";
import { Engine } from "@babylonjs/core/Engines/engine";

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 scoped on @babylonjs.

Usage

See our ES6 dedicated documentation:

import { Engine } from "@babylonjs/core/Engines/engine";
import { Scene } from "@babylonjs/core/scene";
import { Vector3 } from "@babylonjs/core/Maths/math";
import { FreeCamera } from "@babylonjs/core/Cameras/freeCamera";
import { HemisphericLight } from "@babylonjs/core/Lights/hemisphericLight";

// Side-effects only imports allowing the standard material to be used as default.
import "@babylonjs/core/Materials/standardMaterial";
// import the individual builders or use MeshBuilder to have them all
import { CreateSphere } from "@babylonjs/core/Meshes/Builders/sphereBuilder";
import { CreateGround } from "@babylonjs/core/Meshes/Builders/groundBuilder";

const canvas = document.getElementById("renderCanvas") as HTMLCanvasElement;
const engine = new Engine(canvas);
var scene = new Scene(engine);

// This creates and positions a free camera (non-mesh)
var camera = new FreeCamera("camera1", new Vector3(0, 5, -10), scene);

// This targets the camera to scene origin
camera.setTarget(Vector3.Zero());

// This attaches the camera to the canvas
camera.attachControl(canvas, true);

// This creates a light, aiming 0,1,0 - to the sky (non-mesh)
var light = new HemisphericLight("light1", new Vector3(0, 1, 0), scene);

// Default intensity is 1. Let's dim the light a small amount
light.intensity = 0.7;

// Our built-in 'sphere' shape. Params: name, options, scene
var sphere = CreateSphere("sphere1", { segments: 16, diameter: 2 }, scene);

// Move the sphere upward 1/2 its height
sphere.position.y = 2;

// Our built-in 'ground' shape. Params: name, options, scene
CreateGround("ground1", { width: 6, height: 6, subdivisions: 2 }, this._scene);

engine.runRenderLoop(() => {
    scene.render();
});
