node-three-gltf's Issues

loader.setRequestHeader is not a function

const gltf = await loadGltf('./temp/shoes.glb');

error: loader.setRequestHeader is not a function

TypeError: Cannot read properties of undefined (reading 'extensions')

Hi there. I tried to replicate your example. My draco-compressed gltf file was not processed and console.logs were not generated. Was there something missing?

Error log:

Node.js v18.14.0

index.js:

// Import Express, set up the homepage route, and use only ES modules
import express from 'express';
import loadModel from './src/js/loadModel.js';

const app = express();
const port = 3000;

app.get('/', async (req, res) => {
    const fileData = await loadModel();
    console.log('What is this?', fileData);
}
);

app.listen(port, () => {
    console.log(`Example app listening at http://localhost:${port}`);
}
);

/js/loadModel.js:

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

const loadModel = async () => {
    const filePath = './src/assets/dracoModel.gltf';

    if (!fs.existsSync(filePath)) {
        console.log('File not found');
        return;
    };
    
    // 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(filePath, 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(filePath);
    console.log(gltf.scene.children);
};

export default loadModel;

Buffer.buffer contains incorrect data

I found geometry.attributes data is wrong.
The reason is Buffer.buffer 's data is ArrayBuffer(8192).

node version: 16
"dependencies": {
"base64-js": "1.5.1",
"node-three-gltf": "1.3.0",
"three": "0.147.0"
}

Filesize

Very large data return from GLTFLoader.

The model size is just 5-6Mb .... but the GLTFLoader loaded data is 324Mb.

Upgrade sharp version

Please, can you upgrade version of sharp to latest (i tested v.0.33.3, work perfect), cause when i use your module inside node-worker, i got this error:

GLTFExporter support

This loader works very well, I think the Three.GLTFExporter for node should be supported as well;
Especially when exporting GLTF models with images

Need help for GLTFLoader scene

Hi,

Thank you for sharing a great library.

I am new to ThreeJS. And I was having trouble using GLTFLoader.

I used useGLTF (@react-three/drei). But it seems that the useGLTF scene and the GLTFLoader scene are different.

I can't use GLTFLoader's scene to render with <primitive object={model.scene} />.

Where did I go wrong? Or is it wrong to use primitive in this case?

Thank you so much.

This is GLTFLoader scene:

And this is useGLTF scene:

This error originated either by throwing inside of an async function without a catch block

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#<Object>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

An error occurs when trying to load this model.

The model shows normally when using GLTFLoader and useGLTF on the Frontend.

TextureLoader return different data between node-three-gltf and threejs on transparent pixel

I load a png image with transparent pixel
threejs is 0,0,0,0

// three_r148/src/extras/ImageUtils.js after line 49
const context = canvas.getContext('2d')
const imageData = context.getImageData(0, 0, canvas.width, canvas.height);
console.log(imageData)
for (let i = 0; i < imageData.width * imageData.height; i++) {
	const r = imageData.data[i * 4]
	const g = imageData.data[i * 4 + 1]
	const b = imageData.data[i * 4 + 2]
	const a = imageData.data[i * 4 + 3]
	console.log(i, '--', r, g, b, a)
}

node-three-gltf is 255,255,255,0

const textureLoader = new TextureLoader()
const metalnessMap = await textureLoader.loadAsync('./assets/textures/metalness.png')
// metalnessMap.encoding = sRGBEncoding

if (metalnessMap?.source?.data) {
    const imageData = metalnessMap.source.data
    for (let i = 0; i < imageData.width * imageData.height; i++) {
        const r = imageData.data[i * 4]
        const g = imageData.data[i * 4 + 1]
        const b = imageData.data[i * 4 + 2]
        const a = imageData.data[i * 4 + 3]
        console.log(i, '--', r, g, b, a)
    }
}

setMeshoptDecoder must be called before loading compressed files

import {
  DRACOLoader,
  GLTFLoader,
  loadGltf as loadAsync,
} from "node-three-gltf";
import { MeshoptDecoder } from "three-stdlib";

export const loadGltf = async (url: string) => {
  const gltf = new GLTFLoader();
  const draco = new DRACOLoader();
  gltf.setDRACOLoader(draco);
  gltf.setMeshoptDecoder(MeshoptDecoder);

  return await loadAsync(url);
};

results in

Error: THREE.GLTFLoader: setMeshoptDecoder must be called before loading compressed files

How can I load compressed gltfs?
