node-three-gltf

This package offers a modified three.js GLTFLoader to load glTF files in a Node.js environment. Files can be loaded from local file system or from web resources. DRACO-compressed glTF files are also supported. GLTFExporter lets you parse a three.js scene and store it as json or binary file.

In order to work in a non-browser environment, following classes had to be adopted from three.js and modified:

• GLTFLoader
• DRACOLoader
• GLTFExporter
• FileLoader
• ImageLoader
• TextureLoader

All are exposed and can be used independently.

Usage

Install via NPM:

npm install node-three-gltf

Use with ES modules or TypeScript:

import { DRACOLoader, GLTFExporter, GLTFLoader, loadGltf, TextureLoader } from 'node-three-gltf';

// init GLTFLoader and pass a path to a local file or a url to a web resource
const loader = new GLTFLoader();
loader.setDRACOLoader(new DRACOLoader());

loader.load('path/to/file', (gltf) => {
  console.log(gltf.scene.children);
});

// there is also a small utility function that instantiates GLTFLoader and DRACOLoader
// and returns a Promise with the loaded content
const gltf = await loadGltf('path/to/file');
console.log(gltf.scene.children);

// use GLTFExporter to export a scene or objects as json .gltf or binary .glb file
const exporter = new GLTFExporter();

const jsonData = exporter.parseAsync(scene);
fs.writeJson('export.gltf', jsonData, { spaces: 2 });

const glbBuffer = await exporter.parseAsync(scene, { binary: true });
fs.writeFile('export.glb', glbBuffer);

// use TextureLoader, ImageLoader, or FileLoader independently
new TextureLoader().load('path/to/file', (texture) => {
  console.log(texture);
});
