## What it is
three.js is a lightweight, general-purpose JavaScript 3D library for the web, providing scene graphs, cameras, materials, lights, loaders, and animation built on WebGL and WebGPU renderers, with SVG and CSS3D renderers available as addons. It is the de facto standard for rendering interactive 3D content in browsers, including WebXR-based VR and AR experiences.

## Use cases
- render 3d scenes in the browser
- build a 3d product configurator on a website
- create a web-based 3d game
- show 3d models like gltf in a web page
- build a virtual reality experience with webxr
- visualize 3d data or geometry interactively
- add animated 3d graphics to a landing page

## When to choose
- you need interactive 3D rendering in a browser with broad device support
- you want a mature ecosystem with extensive examples, docs, and community
- you need WebXR support for VR/AR in the browser
- you want a lightweight library rather than a full game engine

## When to avoid
- you need a full game engine with physics, editor, and asset pipeline out of the box
- you are doing native (non-web) 3D development
- you need offline desktop 3D rendering without a browser environment

## Facets
- artifact type: library
- maturity: stable
- function: graphics, animation, game-engine
- domain: web-development, graphics, frontend
- platform: browser, cross-platform
- tags: webgl, webgpu, webxr, 3d-graphics, rendering, virtual-reality, augmented-reality, threejs, game-development, javascript
