Three.js -将平面缩放到全屏

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

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

// 创建透视相机
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);

// 创建平面
const geometry = new THREE.PlaneGeometry(2, 2); // 设置平面大小为2x2
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 }); // 设置平面颜色为绿色
const plane = new THREE.Mesh(geometry, material);

// 将平面添加到场景中
scene.add(plane);

// 调整相机位置和视角
function resize() {
  camera.aspect = window.innerWidth / window.innerHeight;
  camera.updateProjectionMatrix();
  renderer.setSize(window.innerWidth, window.innerHeight);
}
window.addEventListener('resize', resize);
resize();

// 渲染循环
function animate() {
  requestAnimationFrame(animate);
  // 更新场景中的元素
  // ...
  // 渲染场景
  renderer.render(scene, camera);
}
animate();
