What is it?

Babylon.js is an open-source 3D engine for building games, interactive scenes and visualizations that run in a web browser. It is written in TypeScript and distributed as a JavaScript framework with full typing support, so it can be installed from npm, loaded from a CDN for experiments, or bundled into a larger application.

The engine provides a scene graph with cameras, lights, meshes and built-in shape builders, and can import glTF and .babylon scene files. Its rendering targets include WebGL, WebGPU and WebXR for virtual and augmented reality, and it exposes Web Audio for sound. A public playground and sample collection let developers test API calls in the browser before writing code.

The project's documentation covers setup, the npm ES6 packages for tree shaking, and a set of exporters for 3ds Max, Maya and Blender. The CDN is intended for learning and small experiments rather than production use.

Key features

  • 01Renders 3D scenes with WebGL, WebGPU and WebXR support.
  • 02Imports glTF and .babylon scene files.
  • 03Provides built-in mesh builders, cameras, lights and materials.
  • 04Ships as npm packages with TypeScript typings and ES6 modules for tree shaking.
  • 05Includes an online playground and many samples for learning the API.

Use cases

  • Building browser-based 3D games or interactive experiences.
  • Creating web visualizations and product viewers with 3D models.
  • Developing WebXR applications for VR and AR headsets.
  • Prototyping 3D ideas quickly in the online playground before writing a project.

Quick start

  1. 1

    Install Babylon.js from npm

    npm install babylonjs --save
  2. 2

    Import Babylon.js in your code

    import * as BABYLON from 'babylonjs';
  3. 3

    Create an engine, scene and render loop using the usage example from the README

Things to know

  • The CDN is not meant for production use, so you must host the packages yourself for real apps.
