如何在Three.js中加载带有三角形和(隔离)顶点的PLY网格？

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

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

// 加载PLY文件
const loader = new THREE.PLYLoader();
loader.load('path/to/your/ply/file.ply', function (geometry) {
  // 创建材质和网格
  const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
  const mesh = new THREE.Mesh(geometry, material);

  // 添加网格到场景
  scene.add(mesh);

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