three.js 显示图片

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

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

// 创建相机
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);

// 加载图片作为纹理
const textureLoader = new THREE.TextureLoader();
textureLoader.load('path/to/your/image.jpg', (texture) => {
    // 创建一个平面几何体
    const geometry = new THREE.PlaneGeometry(2, 2);
    
    // 创建材质并应用纹理
    const material = new THREE.MeshBasicMaterial({ map: texture });
    
    // 创建网格对象
    const plane = new THREE.Mesh(geometry, material);
    
    // 将网格对象添加到场景中
    scene.add(plane);
});

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