尝试在three.js中移动圆柱体对象的透视，而不实际移动它的位置

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

// 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);

// 创建圆柱体对象
const geometry = new THREE.CylinderGeometry(1, 1, 2, 32);
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cylinder = new THREE.Mesh(geometry, material);
scene.add(cylinder);

// 渲染循环
function animate() {
  requestAnimationFrame(animate);

  // 改变相机的位置和方向
  camera.position.x = Math.sin(Date.now() * 0.001) * 5;
  camera.position.y = Math.cos(Date.now() * 0.001) * 5;
  camera.lookAt(scene.position);

  // 渲染场景和相机
  renderer.render(scene, camera);
}

animate();
