HTML5 transform三维立方体实现360无死角三维旋转效果

程序员文章站 2023-11-05 23:23:52
使用HTML5 transform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,美中不足的是无法判断旋转时判断每个面的视图顺序,喜欢的朋友可以了解下... 14-08-22...
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!

代码如下:

<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。
