three.js创建平面

// 引入 three.js 库

// 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);

// 创建平面几何体
const planeGeometry = new THREE.PlaneGeometry(10, 10);  // 宽度和高度均为 10

// 创建平面材质
const planeMaterial = new THREE.MeshBasicMaterial({color: 0x00ff00, side: THREE.DoubleSide});  // 绿色，双面可见

// 创建平面网格
const plane = new THREE.Mesh(planeGeometry, planeMaterial);

// 将平面添加到场景中
scene.add(plane);

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