three.js显示隐藏模型

// 引入three.js库
import * as THREE from 'three';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.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);

// 创建一个立方体
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);

camera.position.z = 5;

// 添加轨道控制
const controls = new OrbitControls(camera, renderer.domElement);

// 显示/隐藏函数
function toggleVisibility() {
    cube.visible = !cube.visible;
}

// 创建按钮并添加事件监听
const button = document.createElement('button');
button.textContent = 'Toggle Cube';
button.onclick = toggleVisibility;
document.body.appendChild(button);

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