three.js 加载stl

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

// 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STL加载器
const loader = new STLLoader();

// 加载STL文件
loader.load('path/to/your/model.stl', function (geometry) {
    // 创建材质
    const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
    
    // 创建网格并添加到场景中
    const mesh = new THREE.Mesh(geometry, material);
    scene.add(mesh);

    // 设置相机位置
    camera.position.z = 5;

    // 渲染循环
    function animate() {
        requestAnimationFrame(animate);
        mesh.rotation.x += 0.01;
        mesh.rotation.y += 0.01;
        renderer.render(scene, camera);
    }
    animate();
});
