HTML5 transform三维立方体（带旋转效果）

为了更好得掌握transform的精髓，所以决定完成三维立方体的模型，可以实现360无死角的三维旋转效果。

但是旋转时判断每个面的视图顺序比较困难，仍未完美解决，希望有人能解答！

源码直接贡献啦：

<style>
.cuboid_side_div{
	position:absolute;
	border:1px solid #333;
	-webkit-transition:ease all 1s;
}
</style>

<script>

/**
  * 本版本存在以下问题：
  * 三维旋转的zIndex计算有问题
  * 还欠缺多种模型，常见的包括：线、面、椎体、球体、椭球体等。
