示例代码如下：
<style>
*{margin:0padding:0}/*简单可以自定义，参照上面*/
body{font:14px/1.5 "\5FAE\8F6F\96C5\9ED1","\5B8B\4F53", sans-serif, Arial, Systembackground-color:#FFF}
#imgg{animation:imgg 1s linear 0s infinite}
@keyframes imgg{0% {transform:rotateY(0deg)}25%{transform:rotateY(90deg)}50%{transform:rotateY(180deg)}75%{transform:rotateY(270deg)}100% {transform:rotateY(360deg)}}
</style>
<div id="demo">
<img src="图片地址" alt="" width="100" height="100" id="imgg">
</div>
html5中引入3d模型的方法是借助第三方PlayCanvas插件来完成的。比如可以用以下方法实现图片的360度旋转：
代码示例：
var render, loop, t, dt, //定义变量
DEG2RAD = Math.PI / 180, //角度转弧度
cvs = document.querySelector('canvas'), //创建canvas
ctx = cvs.getContext('2d'),//绘制2d图形上下文
teddy = new Image(), //创建图像
heart = new Image(), //创建图像中心
angle = 0,//初始化角度为0
reqAnimFrame =
window.requestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.msRequestAnimationFrame ||
window.oRequestAnimationFrame
//创建动画帧
cvs.width = 400
cvs.height = 200
teddy.src = 'xxx.jpg'
heart.src = 'yyy.jpg'
//开始渲染
render = function (timestamp) {
dt = timestamp - t
t = timestamp
// cavas设置为白色
ctx.fillStyle = "rgb(255,255,255)"
ctx.fillRect(0, 0, cvs.width, cvs.height)
// 绘制中心
ctx.drawImage(heart, -20, -120)
// 绘制teddy
ctx.save()
ctx.translate(cvs.width/2, cvs.height/2)// 移动鼠标到画布中心
ctx.rotate(DEG2RAD * angle)// 旋转画布
ctx.drawImage(teddy, -teddy.width/2, -teddy.height/2)// 绘制中心图片
angle += dt / 16.67 * 6// increment angle ~ 360 deg/sec
ctx.restore()
}
loop = function (timestamp) {
reqAnimFrame(loop)
render(timestamp)
}
t = Date.now()
loop(t)
