Use it first, then decide how deep to go

This block should tell both the user and the agent what to copy, install, and apply first.

npm i @babylonjs/core
import {
  Engine, Scene, ArcRotateCamera, HemisphericLight, MeshBuilder, Vector3,
} from "@babylonjs/core";

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

const camera = new ArcRotateCamera("cam", -Math.PI / 2, Math.PI / 3, 10, Vector3.Zero(), scene);
camera.attachControl(canvas, true);

new HemisphericLight("light", new Vector3(0, 1, 0), scene);
MeshBuilder.CreateGround("ground", { width: 10, height: 10 }, scene);
const box = MeshBuilder.CreateBox("box", { size: 2 }, scene);
box.position.y = 1;

engine.runRenderLoop(() => scene.render());
window.addEventListener("resize", () => engine.resize());
Intro

Babylon.js is a powerful, beautiful, simple, and open 3D game and rendering engine for the web. Originally created at Microsoft by David Catuhe, it brings AAA-game-engine features (PBR, physics, advanced post-processing, VR/AR) into a single JavaScript/TypeScript framework. Used by Adobe, Airbus, Siemens, and many enterprises.

What Babylon.js Does

  • PBR materials — physically based rendering with IBL
  • Node Material Editor — visual shader authoring
  • Playground — online IDE for experiments and sharing
  • GUI system — 2D and 3D in-scene UI
  • Physics — Havok, Cannon, Oimo integrations
  • Animation — keyframe, skeletal, morph targets, FBX import
  • Post-processing — bloom, DOF, SSAO, motion blur
  • WebXR — VR/AR with controller support
  • WebGPU — experimental next-gen backend
  • glTF 2.0 — first-class import with KHR extensions

Architecture

Engine manages the GL/GPU context. Scene holds Cameras, Lights, Meshes, Materials, Nodes. Mesh builders provide primitives; loaders handle glTF/OBJ/STL/BabylonNative formats. Everything is strongly typed with TypeScript.

Self-Hosting

Client library.

Key Features

  • PBR materials
  • Node Material Editor (visual shaders)
  • WebGL + WebGPU backends
  • Physics plugins (Havok, Cannon, Oimo)
  • WebXR (VR/AR)
  • glTF 2.0 loader
  • Built-in Inspector for debugging
  • Playground IDE
  • GUI system (2D + in-scene 3D)
  • TypeScript-first

Comparison

Engine Focus Ecosystem Languages
Babylon.js Games + enterprise 3D Large TS/JS
Three.js Flexible 3D lib Largest JS
PlayCanvas Collab editor Medium JS
Unity WebGL Full game engine Huge C#
Godot HTML5 Full game engine Medium GDScript

常见问题 FAQ

Q: Babylon.js vs Three.js？ A: Babylon 是完整游戏引擎（场景、物理、动画、编辑器），开箱即用；Three.js 是更小的 3D 库，更灵活但需要自己拼工具链。企业项目多选 Babylon，艺术/实验多选 Three。

Q: 支持 WebGPU 吗？ A: 支持。启用 WebGPUEngine（仍在完善中）。v7+ 渐进式可用。

Q: 用 Node Material Editor？ A: 可视化节点编辑器，在线设计 shader 后导出为 Babylon 材质。不需要写 GLSL 也能做复杂效果。
