three.js 室内场景

// 示例代码：添加多种光源
const ambientLight = new THREE.AmbientLight(0x404040); // 环境光
scene.add(ambientLight);

const directionalLight = new THREE.DirectionalLight(0xffffff, 0.5); // 方向光
directionalLight.position.set(1, 1, 1);
scene.add(directionalLight);

const pointLight = new THREE.PointLight(0xff0000, 1, 100); // 点光源
pointLight.position.set(0, 5, 0);
scene.add(pointLight);

// 示例代码：使用 LOD 技术
const lod = new THREE.LOD();

for (let i = 0; i < levels; i++) {
    const geometry = new THREE.BoxGeometry(1, 1, 1);
    const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
    const mesh = new THREE.Mesh(geometry, material);
    lod.addLevel(mesh, i * 10); // 每个级别的距离
}

scene.add(lod);

// 示例代码：使用 OrbitControls
const controls = new THREE.OrbitControls(camera, renderer.domElement);
controls.enableDamping = true; // 启用阻尼效果
controls.dampingFactor = 0.25;
controls.enableZoom = true; // 启用缩放
