官方演示地址：【http://www.hewebgl.com/code/show/4.html】
對於一個後端Java開發來說，炫酷的網頁是非常有吸引力的。各種特效、動態效果也很容易吸引住網友的注意力。
最近一直想給自己的博客【www.tecchen.xyz】 做個獨立的主頁， 博客僅僅作爲其中的一個欄目，所以搜索了各種個人網站的首頁演示效果、代碼及其他大神的博客和主頁。
在看到webgl和three.js時，對其中的特效很感興趣，就copy了官方演示效果的【http://www.hewebgl.com/code/show/4.html】 源碼，並參考【TWaver版3D化學元素週期表-https://www.cnblogs.com/twaver/p/3842177.html】 的效果，得到了下面的代碼。

TODO工作
- 1、一字長蛇特效
- 2、點擊翻轉特效（參考輕鬆一下效果）
- 3、雙擊放大特效
- 4、點擊打開鏈接效果
- 5、實戰（個人網站首頁）
- 6、元素中文及讀音（已完成）
