主要是因为前几天买了一架大疆无人机（😁这里没算打广告啊，大疆就是好~~~），然后公司这几天也不是很忙，所以就想着搞一个无人机模型。起初是想学下3D Max建一个无人机模型，后来不知道怎么。就想试试看看html能不能拼凑一个，虽然很费时间，但是我成功了！！
image.png
这里基本就是用的css+html的一些基础知识，我只不是通过vue框架来写的。主要用于组件化的封装，这样就会节省时间了。下面主要跟大家说下涉及到的知识点和实现思路~~~~
知识点：
1.css+html，涉及了一点js（主要是用来控制无人机的移动用的）；
2.transform-style: preserve-3d; css的3d旋转属性；
3.perspective css的景深属性；
4.filter: drop-shadow ； css的滤镜阴影穿透；
5.svg的path路径填充和描边；
6.animation css动画；
实现思路：

主要讲一下怎么拼成的模型吧。其实并不难，主要是耗时间，慢慢的拼凑。分为3个部分：
机桨(yepian.vue)，机身(shenti.vue)，机架(jijia.vue)，合成部份(index.vue)。

机架和机桨可以合成一个组件，然后其它三个就是公用的了，只需要旋转下角度就可以了。
