从three.js开始的STLLoader.js代码示例？有没有干净的示例代码？

// 引入three.js和STLLoader.js
import * as THREE from 'three';
import { STLLoader } from 'three/examples/jsm/loaders/STLLoader.js';

// 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);

// 创建光源
const light = new THREE.DirectionalLight(0xffffff, 1);
light.position.set(1, 1, 1).normalize();
scene.add(light);

// 创建STLLoader实例
const loader = new STLLoader();

// 加载STL文件并渲染模型
loader.load('path/to/your/model.stl', function (geometry) {
  const material = new THREE.MeshPhongMaterial({ color: 0x00ff00 });
  const mesh = new THREE.Mesh(geometry, material);
  scene.add(mesh);
});

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