three.js水星纹理贴图

Three.js中实现水星纹理贴图的步骤如下：

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

// 创建相机
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

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

// 创建水星球体
var geometry = new THREE.SphereGeometry(1, 32, 32);
var texture = new THREE.TextureLoader().load('mercury.jpg');
var material = new THREE.MeshBasicMaterial({ map: texture });
var mercury = new THREE.Mesh(geometry, material);
scene.add(mercury);

// 渲染场景
function animate() {
    requestAnimationFrame(animate);
    mercury.rotation.y += 0.01;
    renderer.render(scene, camera);
}
animate();

其中，`THREE.TextureLoader().load('mercury.jpg')`用于加载水星的纹理贴图，`THREE.MeshBasicMaterial({ map: texture })`用于将纹理贴图应用到水星球体上。
