## What it is
Galacean Engine is a high-performance, real-time interactive 2D/3D engine written in TypeScript, built on WebGL/WebGL2 with support for animation, physics, GUI, particles, and WebXR. It can be used via pure code (npm package) or a browser-based online editor, and targets web, mobile, and WeChat minigame platforms.

## Use cases
- build 3D games that run in the browser
- create interactive 3D product showrooms with PBR rendering
- develop AR/XR experiences with WebXR
- make 2D sprite-based games and animations for web and WeChat minigames
- render glTF models with lighting, physics, and particle effects
- build digital twin and educational interactive web apps
- collaborate with artists using an online visual scene editor

## When to choose
- you need a lightweight, mobile-first WebGL engine with strong 2D and 3D support
- you want built-in physics, animation, GUI, and particle systems in one engine
- you prefer TypeScript and a component-based architecture
- you want an optional online editor with asset import (.glb, .fbx, .hdr) and project export
- you target WeChat minigames or Alipay mini-programs

## When to avoid
- you need native desktop or console deployment
- you require a very large ecosystem of third-party plugins and community content like Three.js offers
- you need Vulkan/Metal-level graphics features beyond WebGL2
- your project depends on engines with long-established enterprise support contracts
