What is Three.js?

Three.js is a powerful, lightweight JavaScript library that makes creating beautiful and interactive 3D graphics in the browser incredibly accessible. It elegantly abstracts both classic WebGL and the modern WebGPU API, allowing you to focus on creativity rather than low-level graphics code.

Work with familiar high-level objects like scenes, cameras, lights, meshes, geometries, and materials. Easily import models from industry-standard formats such as glTF/GLB, FBX, OBJ, and STL.

Whether you're building product configurators, immersive data visualizations, architectural walkthroughs, web-based games, or artistic 3D experiences — Three.js gives you professional-grade power with developer-friendly simplicity.
