Question

What is the best way to convert a scene or model to GLTF Format in Three.js?

Can I create a Web App with Meteor that exports the scene to GLTF format directly to the server?

If you're searching for a demonstration, check out this sample.

Regarding the server-side aspect, as long as you avoid elements that rely on a browser (such as THREE.WebGLRenderer()), running THREE on a server should be feasible. Here's an interesting example of doing so with a Node server.

Is it possible for someone to have already developed JavaScript code that simplifies exporting glTF from web applications created using Three.js? The answer remains uncertain.

Typically, web applications that produce glTF files rely on a native component such as COLLADA2GLTF or FBX-glTF which runs as a server-side process. An example of this can be seen in the following link:

My preference leans towards GLB over GLTF due to the convenient packaging of textures and animations within a single file, eliminating the need for external references commonly found in GLTF files. With GLB, everything is neatly bundled together for ease of use.

If you wish to convert a THREE.js scene into GLB format, utilize the provided code snippet below👇

const btn = document.getElementById('download-glb')
btn.addEventListener('click',download)

function download(){
    const exporter = new GLTFExporter();
    exporter.parse(
        scene,
        function (result) {
            saveArrayBuffer(result, 'ThreejsScene.glb'); 
        },
        { 
            binary: true
        }
    );
}

function saveArrayBuffer(buffer, filename) {
    save(new Blob([buffer], { type: 'application/octet-stream' }), filename);
}
   
function save(blob, filename) {
    link.href = URL.createObjectURL(blob);    
    link.download = filename;
    link.click(); // Triggering this step ensures the glb file download
    sendFileToBackend(blob, filename)
}

function sendFileToBackend(blob, filename){
    const endpoint = "YOUR_BACKEND_URL_HERE";
    const formData = new FormData();

    let sceneFile= new File([blob], "ThreejsScene.glb");
    console.log(sceneFile)
    formData.append("file", sceneFile);

    const options = {
        method:'POST',
        mode: 'no-cors',
        body: formData,
    }

    fetch(endpoint,options)
        .then(response => console.log(JSON.stringify(response)))
        .catch(error => console.error('Error:', error))

}
