Three.js Loaders

Three.js Loaders

When to Use

• You need to load models, textures, HDR assets, or other external resources in Three.js.
• The task involves GLTFLoader, TextureLoader, loading progress, or async asset orchestration.
• You are managing scene assets rather than authoring geometry or shaders directly.

Quick Start

import * as THREE from "three";
import { GLTFLoader } from "three/addons/loaders/GLTFLoader.js";

// Load GLTF model
const loader = new GLTFLoader();
loader.load("model.glb", (gltf) => {
  scene.add(gltf.scene);
});

// Load texture
const textureLoader = new THREE.TextureLoader();
const texture = textureLoader.load("texture.jpg");

LoadingManager

Coordinate multiple loaders and track progress.

const manager = new THREE.LoadingManager();

// Callbacks
manager.onStart = (url, loaded, total) => {
  console.log(`Started loading: ${url}`);
};

manager.onLoad = () => {
  console.log("All assets loaded!");
  startGame();
};
