序：前段时间公司一次研讨会上，一市场部同事展现了同行业其他公司的3D机房，我司领导觉得这个可以研究研究，为了节约成本，我们在网上大量检索，派本人研究一下web3D的技术，于是乎便有了下面的技术分享。
一、本着开源的思想，使用three.js框架，封装常用的模型库。先学着那位前辈的样子，使用ThreeJS画出类似的效果图，只是稍微有点丑，看官莫怪。
二、源码
封装自己的模型库，这是初始的模型库，较为简陋了 ，牛逼的库都是不断的迭代个几百次的，不到的地方还望指正，互相学习共同进步
--这里封装一下 就叫做.js--

该封的都封好了
然后就创建一个页面直接运行呗，那就简单了，直接在onload事件里面调用一下 就行了。

后面再加博文讲解吧。
本人也是three.js的初学者，不正的地方，还望大牛前辈指点。
