将SVG包含到three.js模块中，以避免单独HTTP请求

const loader = new THREE.SVGLoader();
loader.load('path/to/svg/file.svg', function (data) {
  // 处理加载完成的SVG数据
});

const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

const loader = new THREE.SVGLoader();
loader.load('path/to/svg/file.svg', function (data) {
  const paths = data.paths;
  const group = new THREE.Group();

  for (let i = 0; i < paths.length; i++) {
    const path = paths[i];

    const material = new THREE.MeshBasicMaterial({
      color: path.color,
      side: THREE.DoubleSide,
      depthWrite: false
    });

    const shapes = path.toShapes(true);

    for (let j = 0; j < shapes.length; j++) {
      const shape = shapes[j];
      const geometry = new THREE.ShapeGeometry(shape);
      const mesh = new THREE.Mesh(geometry, material);
      group.add(mesh);
    }
  }

  scene.add(group);
});

camera.position.z = 5;

function animate() {
  requestAnimationFrame(animate);
  renderer.render(scene, camera);
}

animate();
