Drei

Drei is a large collection of ready-made helpers and abstractions for React Three Fiber, maintained by Poimandres, the open-source collective behind the pmndrs libraries. It wraps common 3D tasks as components and hooks, such as camera controls, environment lighting, text, HTML overlays, model loading, shaders, materials and performance helpers, so scenes need far less boilerplate. It is the usual companion for designers and engineers building 3D web experiences in React.
