Answer:
Three.js is a front-end JavaScript library for creating 3D graphics and animations in the browser using WebGL. It operates entirely on the client side, rendering 3D scenes directly in the browser canvas element. Three.js has no back-end role - it consumes data and assets from server-side APIs but all rendering execution occurs in the browser. In 2026, Three.js is widely used for product visualisations, interactive experiences, and browser-based game development.
