Three.js

threejs.org
Open source

Three.js is a cross-browser JavaScript library and API used for creating and displaying animated 3D computer graphics in web browsers. It utilizes WebGL for hardware-accelerated rendering, but can fall back on other rendering modes for older browsers. Three.js simplifies the complexity of 3D graphics programming, providing high-level abstractions for scenes, cameras, lights, and materials. It's widely used for creating 3D visualizations, games, product configurators, and immersive web experiences. Three.js supports various features including realistic lighting, shadows, textures, and even VR content creation.

Three.js belongs toJavaScript graphicscategory.
