更改文本颜色Three.js

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

// 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();

// 设置渲染器的尺寸
renderer.setSize(window.innerWidth, window.innerHeight);

// 将渲染器的输出添加到HTML文档中
document.body.appendChild(renderer.domElement);

// 创建3D文本对象
const loader = new THREE.FontLoader();
loader.load('fonts/helvetiker_regular.typeface.json', function (font) {
  const textGeometry = new THREE.TextGeometry('Hello World', {
    font: font,
    size: 80,
    height: 5,
    curveSegments: 12,
    bevelEnabled: true,
    bevelThickness: 10,
    bevelSize: 8,
    bevelSegments: 5
  });

  // 创建材质并设置颜色
  const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
  
  // 创建网格对象并将文本几何体与材质结合
  const textMesh = new THREE.Mesh(textGeometry, material);
  
  // 将网格对象添加到场景中
  scene.add(textMesh);
});

// 设置相机位置
camera.position.z = 5;

// 创建动画循环函数
function animate() {
  requestAnimationFrame(animate);
  
  // 旋转文本对象
  textMesh.rotation.x += 0.01;
  textMesh.rotation.y += 0.01;
  
  // 渲染场景
  renderer.render(scene, camera);
}

// 调用动画循环函数
animate();
