3d滚动球体js动画代码

以下是一个使用 JavaScript 和 Three.js 库实现 3D 滚动球体的简单动画代码示例：

  <script>
    // 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);

    // 创建球体几何体和材质
    const geometry = new THREE.SphereGeometry(1, 32, 32);
    const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });

    // 创建球体网格并添加到场景
    const sphere = new THREE.Mesh(geometry, material);
    scene.add(sphere);

    // 动画函数
    function animate() {
      requestAnimationFrame(animate);

      // 使球体沿 x 轴滚动
      sphere.rotation.x += 0.01;
      sphere.rotation.y += 0.01;

      renderer.render(scene, camera);
    }

    animate();

    // 监听窗口大小变化，调整渲染器尺寸
    window.addEventListener('resize', () => {
      camera.aspect = window.innerWidth / window.innerHeight;
      camera.updateProjectionMatrix();
      renderer.setSize(window.innerWidth, window.innerHeight);
    });
  </script>
</body>
