怎么样使用原生javascript+css3编写3D魔方动画旋扭特效?

一直从事于后端编程工作,工作中也经常接触和使用一些前端技术,但大多数还是用于操作和控制数据与客户端交互工作。随着互联网技术的发展以及硬件性能的不断提升,人们对于交互式体验已变得越来越重视,进而前端技术已经越来越突显出它的重要性,特别是一些炫酷的特效,精美的UI设计,都使人眼前一亮,顿时觉得网站平台都高大上不少,很博人们眼球,给人们以很好的视觉冲击,特别是现在的css3,HTML5技术的更新,使得以更小的代价就可以轻松实现这些效果,故此,顿时膜拜起前端技术,悠然起了兴趣,跃跃欲试,随机利用css3的新增3D特效技术及动画特效功能加原生态javascript写了一个随机打乱旋扭的魔方,在指定的步数后,魔方按记录的动作,逆行旋扭重新归位。随即发布出来与大家分享,也希望前端的大牛能指点一二,不甚感激!

注:在此基础上可以加上鼠标控制事件,可以直接通过鼠标控制器任意方向的旋扭,也可以稍加改进用于炫酷展示图片!后续有时间我将加上这些功能,与大家再次分享!
