本帖使用 glTF 模型制作 ThreeJS 3d 图像，模型URL在 42 行代码：

gbl = 'https://638183.freep.cn/638183/web/3models/Parrot.glb'

鹦鹉是 ThreeJS 提供的 glTF 建模资源，类似的还有：

鹳：Stork
火烈鸟：Flamingo

这两个都上传了，地址修改一下即可，就是替换掉 Parrot 即可

第 33 行代码：

camera.position.set(10, 10, -10);

设置相机的位置。由于引入了轨道控制器 OrbitControls ，相机是可以手动翻转、伸缩的，上面的代码只是相机位置的初始位置，目的是调整鹦鹉的姿态，实际使用时可以视情况改变相应数据，xyz轴上的数据每一个建议在 -10 ~ 10 之间。

第 50~53行代码：

if (gltf.animations.length > 0) {
const clip = mixer.clipAction(gltf.animations[0]);
clip.play();
}

判断模型是否自带动画，如果是，运行它的第一个动画。

有些模型是静态模型，如果需要加入动画，需要帖子制作者自己设计基于 ThreeJS 的其它动画，代码放在 animate 函数内。
