        HTML5 transform三維立方體實(shí)現(xiàn)360無死角三維旋轉(zhuǎn)效果

        字號(hào):


            為了更好得掌握transform的精髓,所以決定完成三維立方體的模型,可以實(shí)現(xiàn)360無死角的三維旋轉(zhuǎn)效果。
            但是旋轉(zhuǎn)時(shí)判斷每個(gè)面的視圖順序比較困難,仍未完美解決,希望有人能解答!
            源碼直接貢獻(xiàn)啦:
            代碼如下:
            <style>
            .cuboid_side_div{
            position:absolute;
            border:1px solid #333;
            -webkit-transition:ease all 1s;
            }
            </style>
            <script>
            /**
            * 本版本存在以下問題:
            * 三維旋轉(zhuǎn)的zIndex計(jì)算有問題
            * 還欠缺多種模型,常見的包括:線、面、椎體、球體、橢球體等。
