以下是我完成的三个3D模型(内有分析和源代码)

3d html5 如何保存 html 3d模型_css_03


主要是使用:

-webkit-perspective:1000px;/透视距/

transform-style: preserve-3d;/指定嵌套元素如何在3D空间中呈现。他主要有两个属性值:flat(就是2D的)和preserve-3d。/

transform对3D模型进行操作;

我们首先要准备一个平台作为基准(也就是所有的3D元素的父节点),也就是一个三维坐标的原点,以此来对HTML的各种元素在3D空间中进行旋转、平移;

其中一些元素的用法:
发现rotate3d(20,0,0,45deg),其实就是从原点指向(20,0,0)这个点构成一个方向轴,然后根据左手定则,四指指向方向为旋转方向,旋转45度。因此这样就很好解释了rotate3d(x,y,z,deg)属性,由原点指向(x,y,z)成方向轴,然后左手定则,确定旋转方向,进行相应的角度旋转,得到特效结果。

遇到一些小问题:

transform: rotateY(0deg) translateZ(0px);

里面的rotate和translate 顺序很重要,不同的顺序效果不同;

偷个懒,小技巧。由于要写超多div才能实现一些3D模型,往往这些div没有啥区别,于是想到了JS,利用for循环和div中的规律来自动实现div的加载;

源代码

首先来个最简单的,立方体:

只要明白大概的原理,3D效果的完成就是时间问题,几乎所有的都大同小异
