three.js模拟室内灯光

// 创建场景
const scene = new THREE.Scene();

// 创建相机
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// 创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 添加一个立方体作为室内物体
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshStandardMaterial({ color: 0x808080 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// 添加环境光
const ambientLight = new THREE.AmbientLight(0x404040); // 柔和的白光
scene.add(ambientLight);

// 添加点光源模拟吊灯
const pointLight = new THREE.PointLight(0xffffff, 1, 100);
pointLight.position.set(0, 3, 0);
scene.add(pointLight);

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    cube.rotation.x += 0.01;
    cube.rotation.y += 0.01;
    renderer.render(scene, camera);
}
animate();
