Three.js Loaders

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();
};

manager.onProgress = (url, loaded, total) => {
  const progress = (loaded / total) * 100;
  console.log(`Loading: ${progress.toFixed(1)}%`);
  updateProgressBar(progress);
};

manager.onError = (url) => {
  console.error(`Error loading: ${url}`);
};

// Use manager with loaders
const textureLoader = new THREE.TextureLoader(manager);
const gltfLoader = new GLTFLoader(manager);

// Load assets
textureLoader.load("texture1.jpg");
textureLoader.load("texture2.jpg");
gltfLoader.load("model.glb");
// onLoad fires when ALL are complete

Texture Loading

TextureLoader

const loader = new THREE.TextureLoader();

// Callback style
loader.load(
  "texture.jpg",
  (texture) => {
    // onLoad
    material.map = texture;
    material.needsUpdate = true;
  },
  undefined, // onProgress - not supported for image loading
  (error) => {
    // onError
    console.error("Error loading texture", error);
  },
);

// Synchronous (returns texture, loads async)
const texture = loader.load("texture.jpg");
material.map = texture;

Texture Configuration

const texture = loader.load("texture.jpg", (tex) => {
  // Color space (important for color accuracy)
  tex.colorSpace = THREE.SRGBColorSpace; // For color/albedo maps
  // tex.colorSpace = THREE.LinearSRGBColorSpace;  // For data maps (normal, roughness)

  // Wrapping
  tex.wrapS = THREE.RepeatWrapping;
  tex.wrapT = THREE.RepeatWrapping;
  // ClampToEdgeWrapping, RepeatWrapping, MirroredRepeatWrapping

  // Repeat/offset
  tex.repeat.set(2, 2);
  tex.offset.set(0.5, 0.5);
  tex.rotation = Math.PI / 4;
  tex.center.set(0.5, 0.5);

  // Filtering
  tex.minFilter = THREE.LinearMipmapLinearFilter; // Default
  tex.magFilter = THREE.LinearFilter; // Default
  // NearestFilter - pixelated
  // LinearFilter - smooth
  // LinearMipmapLinearFilter - smooth with mipmaps

  // Anisotropic filtering (sharper at angles)
  tex.anisotropy = renderer.capabilities.getMaxAnisotropy();

  // Flip Y (usually true for standard textures)
  tex.flipY = true;

  tex.needsUpdate = true;
});

CubeTextureLoader

For environment maps and skyboxes.

const loader = new THREE.CubeTextureLoader();

// Load 6 faces
const cubeTexture = loader.load([
  "px.jpg",
  "nx.jpg", // positive/negative X
  "py.jpg",

How to use threejs-loaders on Cursor
AI-first code editor with Composer
1
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add threejs-loaders
2
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
$npx skills add https://github.com/cloudai-x/threejs-skills --skill threejs-loaderscopy
The skills CLI fetches threejs-loaders from GitHub repository cloudai-x/threejs-skills and configures it for Cursor.
3
Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
◆ Which agents do you want to install to?
│
│ ── Universal (.agents/skills) ── always included ────
│   • Amp
│   • Antigravity
│   • Cline
│   • Codex
│ ●Cursor(selected)
│   • Cursor
│   • Windsurf
4
Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/threejs-loaders
Reload or restart Cursor to activate threejs-loaders. Access the skill through slash commands (e.g., /threejs-loaders) or your agent's skill management interface.
⚠
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
