如何使用鼠标单击并拖动仅在X轴上旋转相机？

// 引入Three.js库
import * as THREE from 'three';

// 创建场景、相机和渲染器
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建一个立方体作为示例对象
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// 记录鼠标初始位置的变量
let mouseX = 0;

// 监听鼠标按下事件
document.addEventListener('mousedown', (event) => {
  mouseX = event.clientX;
});

// 监听鼠标移动事件
document.addEventListener('mousemove', (event) => {
  if (event.buttons === 1) {
    const deltaX = event.clientX - mouseX;
    // 将位移量应用到相机的旋转角度上
    camera.rotation.y += deltaX * 0.01;
    mouseX = event.clientX;
  }
});

// 渲染场景
function animate() {
  requestAnimationFrame(animate);
  renderer.render(scene, camera);
}
animate();
