以便更好得把握transform的精粹,因此决策进行3维立方体的实体模型,能够完成360无死角的3维转动实际效果。

可是转动时分辨每一个面的主视图次序较为艰难,仍未完善处理,期待有人能解答!

源代码立即奉献啦:

拷贝编码
编码以下:

<style>
.cuboid_side_div{
position:absolute;
border:1px solid #333;
-webkit-transition:ease all 1s;
}
</style>
<script>
/**
* 本版本号存在下列难题:
* 3维转动的zIndex测算有难题
* 还缺乏多种多样实体模型,普遍的包含:线、面、椎体、球体、椭球体等。
