Three.js

Three.js is a JavaScript library for creating interactive 3D graphics in web browsers. Developers use it to build 3D visualizations and experiences that run across different platforms using WebGL, WebGPU, and Canvas rendering. The library supports various web technologies including SVG, HTML5, and Web Audio, and can be used for applications like augmented reality and virtual reality experiences. Three.js is developed by mrdoob and distributed under the MIT License, making it free to use and modify. The project includes comprehensive documentation, examples, and tools to help developers get started with 3D web development. An active community provides support through forums, Discord, and other channels.

The library abstracts complex graphics programming concepts, allowing developers to work with 3D objects, cameras, lighting, and materials without writing low-level graphics code directly. Three.js handles the underlying WebGL or WebGPU calls needed to render 3D scenes in the browser. Its cross-platform nature means the same code can run on different devices and browsers that support modern web standards, making it suitable for creating web-based 3D applications that reach a broad audience.
