如何在Three.js中将线框添加到实例化网格

// 步骤1：导入Three.js库文件
import * as THREE from 'three';

// 步骤2：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;

// 步骤3：创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 步骤4：创建几何体和材质
const geometry = new THREE.BoxGeometry(1, 1, 1);
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });

// 步骤5：创建网格对象
const cube = new THREE.Mesh(geometry, material);

// 步骤6：创建线框几何体
const wireframeGeometry = new THREE.WireframeGeometry(geometry);

// 步骤7：创建线框材质
const wireframeMaterial = new THREE.MeshBasicMaterial({ color: 0xff0000, linewidth: 2 });

// 步骤8：创建线框网格
const wireframe = new THREE.LineSegments(wireframeGeometry, wireframeMaterial);

// 步骤9：将线框网格添加到场景中
scene.add(wireframe);

// 步骤10：将网格对象添加到场景中
scene.add(cube);

// 步骤11：渲染场景和相机
function animate() {
  requestAnimationFrame(animate);
  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;
  renderer.render(scene, camera);
}
animate();
