1.下载glTF文件
可以从sketchfab上下载模型，例如我下载了下面这个模型。
2.three.js加载glTF文件的代码

loader.load('scene.gltf', function (gltf) {

gltf.scene.scale.set(0.01, 0.01, 0.01);
// 相对X轴旋转弧度(为了让模型加载为合适的姿势)
gltf.scene.rotation.x = -0.5 * Math.PI;
gltf.scene.position.z = 0.8;
scene.add(gltf.scene);
render();
});
const controls = new OrbitControls(camera, renderer.domElement);
controls.addEventListener('change', render);
controls.minDistance = 2;
controls.maxDistance = 10;
controls.target.set(0, 0, 0);
controls.update();
}
function render() {
renderer.render(scene, camera);
};
