Three.js is an open-source JavaScript 3D library originally created by Ricardo Cabello (mrdoob) in 2010 and now maintained by a broad community of contributors. It abstracts WebGL and WebGPU behind a clean object-oriented API — Scenes, Cameras, Lights, Geometries, Materials, Textures, Loaders, Controls, Animation, and Post-Processing — to make interactive 3D in the browser practical for games, product configurators, data visualization, generative art, GIS, scientific visualization, simulations, AR/VR (WebXR), and creative coding. The library ships as the `three` npm package under MIT license with a rich addon ecosystem (`three/addons/*`) including dozens of loaders for industry asset formats (glTF, OBJ, FBX, USDZ, KTX2, DRACO), controls, helpers, post-processing passes, and a node-based shading language (TSL) that targets both WebGL and WebGPU. A browser-based editor at threejs.org/editor produces scenes in a documented JSON object format. Three.js has become the de-facto foundation for the JavaScript 3D ecosystem and underpins higher-level projects including React Three Fiber, A-Frame, model-viewer, Threlte, and TroisJS.
