@react-three/drei

What is @react-three/drei?

@react-three/drei is a collection of useful helpers and abstractions for react-three-fiber, which is a React renderer for three.js. It provides a wide range of components and utilities to simplify the creation of 3D scenes in React applications.

What are @react-three/drei's main functionalities?

Camera Controls

The OrbitControls component allows you to easily add camera controls to your 3D scene, enabling users to rotate, zoom, and pan the camera.

import { OrbitControls } from '@react-three/drei';

function Scene() {
  return (
    <Canvas>
      <OrbitControls />
      {/* other components */}
    </Canvas>
  );
}

Environment

The Environment component allows you to quickly set up a realistic lighting environment using HDRI images. You can choose from various presets like 'sunset', 'dawn', 'night', etc.

import { Environment } from '@react-three/drei';

function Scene() {
  return (
    <Canvas>
      <Environment preset="sunset" />
      {/* other components */}
    </Canvas>
  );
}

Loading Models

The useGLTF hook allows you to easily load and display GLTF models in your scene. It returns the loaded scene, which you can then use as a primitive object.

import { useGLTF } from '@react-three/drei';

function Model() {
  const { scene } = useGLTF('/path/to/model.glb');
  return <primitive object={scene} />;
}

function Scene() {
  return (
    <Canvas>
      <Model />
      {/* other components */}
    </Canvas>
  );
}

Text

The Text component allows you to easily add 3D text to your scene. You can customize the font, size, color, alignment, and other properties.

import { Text } from '@react-three/drei';

function Scene() {
  return (
    <Canvas>
      <Text
        color="black"
        fontSize={1}
        maxWidth={200}
        lineHeight={1}
        letterSpacing={0.02}
        textAlign={'left'}
        font="/path/to/font.woff"
        anchorX="center"
        anchorY="middle"
      >
        Hello World
      </Text>
      {/* other components */}
    </Canvas>
  );
}

Other packages similar to @react-three/drei

three

Three.js is the core library for creating 3D graphics in the browser. While it provides a comprehensive set of features for 3D rendering, it requires more boilerplate code compared to @react-three/drei, which offers higher-level abstractions and components.

react-three-fiber

React-three-fiber is a React renderer for three.js. It allows you to build and manage 3D scenes using React components. @react-three/drei is built on top of react-three-fiber and provides additional helpers and components to simplify common tasks.

aframe

A-Frame is a web framework for building virtual reality experiences. It is built on top of three.js and provides a declarative, HTML-like syntax for creating 3D scenes. While it is not React-based, it offers similar functionalities for building 3D environments.
