const geometry = new THREE.BoxGeometry(1, 1, 1) const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 }) const cube = new THREE.Mesh(geometry, material)

const loader = new THREE.GLTFLoader() loader.load('model.glb', function(gltf) { scene.add(gltf.scene) })

const geometry = new THREE.BoxGeometry() const material = new THREE.MeshBasicMaterial() const mesh = new THREE.InstancedMesh(geometry, material, 100)
