Examples are in the /examples directory. Live versions can be found in the links below.
Interactive Examples:
Full example in examples/react-three-fiber
function ChurchModel() {
const { gl } = useThree()
const url = 'https://engine.needle.tools/demos/gltf-progressive/assets/church/model.glb'
const { scene } = useGLTF(url, false, false, (loader) => {
useNeedleProgressive(url, gl, loader as any)
})
return <primitive object={scene} />
}

In your script:
const gltfLoader = new GLTFLoader();
const url = "https://engine.needle.tools/demos/gltf-progressive/assets/church/model.glb";
// register the progressive loader
useNeedleProgressive(url, renderer, gltfLoader)
// just call the load method as usual
gltfLoader.load(url, gltf => {
console.log(gltf)
scene.add(gltf.scene)
gltf.scene.position.y += .95;
})
