Quick Start
// 1. Scene, Camera, Renderer
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setPixelRatio(window.devicePixelRatio);
document.body.appendChild(renderer.domElement);
// 2. Lighting
scene.add(new THREE.AmbientLight(0x404040));
const dirLight = new THREE.DirectionalLight(0xffffff, 1);
dirLight.position.set(5, 5, 5);
scene.add(dirLight);
// 3. Load GLTF Model
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js';
const loader = new GLTFLoader();
loader.load('model.glb', gltf => scene.add(gltf.scene));
// 4. Animation Loop
function animate() {
requestAnimationFrame(animate);
renderer.render(scene, camera);
}
animate();
