css3 3d 与案例分析
作者:魔洁
聊到3d那我们就先聊聊空间维度,首先一维,比如一条线就是一个一维空间,连点成线在这个空间里这些点只能前进后退,二维空间就是一个平面,这时点不仅可以前进后退还可以左右移动,3维空间也可以说是3d,这时点可以前进后退,左右,上下移动。css3里有几个关于3d运动的属性以及值我做一下解释
transform-style:preserve-3d;(transform-style是属性)(preserve-3d是值)
(这个属性可以把一个处于2维的div变为3d空间,把这个属性比作一个相机的摄像头,这个div内的内容会以3d的形式通过摄像头的形式反馈给你,他的子元素才会享受3d效果,子元素以下的元素就不会有3d效果。)
perspective:800px;
(这个属性是配合上边的属性使用的 ,把这个属性比作你的屏幕距离摄像头的距离)
transform:rotateY(180deg);
(把这个3d空间div看做一个人rotateY(180deg),是做y轴旋转180°,y轴可以看作是一个人原地转身)
transform:rotatex(180deg);
(rotateY(180deg),是做x轴旋转180°,x轴可以看作是一个人原地翻跟斗)
transform:rotateZ(180px);
(rotateZ(180px),是在前进180px,x轴可以看作是一个人向前走180px,负值为后退)
看完这些相信下面的代码回好理解许多。

因为我的背景图是dome061.jpg,dome062.jpg,dome063.jpg,dome064.jpg,dome065.jpg,我会把他们第三位数字声明在名为img的数组里
js
var img=[1,2,3,4,5];
for(var i=0;i<5;i++){
$(‘#a‘).append(‘<div class="fp cs" style="background:url(img/dome06‘+img[i]+‘.jpg);background-size:100% 100%;"></div>‘);
}
//上边的for循环是渲染舞台里演员
//pd是判断按下按钮的变量
var pd=1;
//a是判断演员的下标
var a=4;
$(‘.btn‘).eq(1).click(function(){
if(a<0){
a=4;
}
if(pd==1){
pd++;
$(‘.fp‘).eq(a).removeClass(‘fp‘);//移除fp这个类
$(‘.cs‘).eq(a).addClass(‘fp1‘);//因为演员我定义了两个类把fp移除了,还可以用cs抓起取员
}else{
$(‘.cs‘).eq(a).removeClass(‘fp1‘);
$(‘.cs‘).eq(a).removeClass(‘fp2‘);
$(‘.cs‘).eq(a).removeClass(‘fp3‘);
$(‘.cs‘).eq(a).removeClass(‘fp4‘);
$(‘.cs‘).eq(a).addClass(‘fp2‘);//下标是a的演员移除fp1,fp2,fp3,fp4之后再加fp2
$(‘.fp‘).eq(a-1).removeClass(‘fp‘);
$(‘.cs‘).eq(a-1).removeClass(‘fp1‘);
$(‘.cs‘).eq(a-1).removeClass(‘fp2‘);
$(‘.cs‘).eq(a-1).removeClass(‘fp3‘);
$(‘.cs‘).eq(a-1).removeClass(‘fp4‘);
$(‘.cs‘).eq(a-1).addClass(‘fp1‘);//下标是a-1的演员移除fp,fp1,fp2,fp3,fp4之后再加fp4
a--;
}
console.log(a,pd);
})
$(‘.btn‘).eq(0).click(function(){
if(a>5){
a=0;
}
if(pd==2){
if(a==4){
$(‘.cs‘).eq(a).removeClass(‘fp1‘);
$(‘.cs‘).eq(a).removeClass(‘fp2‘);
$(‘.cs‘).eq(a).removeClass(‘fp3‘);
$(‘.cs‘).eq(a).removeClass(‘fp4‘);
$(‘.cs‘).eq(a).addClass(‘fp3‘);//下标是a的演员移除fp1,fp2,fp3,fp4之后再加fp3
$(‘.cs‘).eq(0).removeClass(‘fp1‘);
$(‘.cs‘).eq(0).removeClass(‘fp2‘);
$(‘.cs‘).eq(0).removeClass(‘fp3‘);
$(‘.cs‘).eq(0).removeClass(‘fp4‘);
$(‘.cs‘).eq(0).addClass(‘fp4‘);//下标是0的演员移除fp1,fp2,fp3,fp4之后再加fp4
}
$(‘.cs‘).eq(a).removeClass(‘fp1‘);
$(‘.cs‘).eq(a).removeClass(‘fp2‘);
$(‘.cs‘).eq(a).removeClass(‘fp3‘);
$(‘.cs‘).eq(a).removeClass(‘fp4‘);
$(‘.cs‘).eq(a).addClass(‘fp3‘);//下标是a的演员移除fp1,fp2,fp3,fp4之后再加fp3
$(‘.cs‘).eq(a+1).removeClass(‘fp1‘);
$(‘.cs‘).eq(a+1).removeClass(‘fp2‘);
$(‘.cs‘).eq(a+1).removeClass(‘fp3‘);
$(‘.cs‘).eq(a+1).removeClass(‘fp4‘);
$(‘.cs‘).eq(a+1).addClass(‘fp4‘);//下标是a+1的演员移除fp1,fp2,fp3,fp4之后再加fp4
a++;
}
//console.log(a,pd);
})
4.旋转木马
按键盘方向键就会旋转
html
<div class=bigbox>
<div class="box">
</div>
</div>
bigbox是摄像头,box是舞台,舞台里的演员我将用js渲染,class为mian
css
.bigbox{
width:150px;
height:100px;
margin:200px auto;
perspective:800px;
transform-style:preserve-3d;
}
.box{
transform-style:preserve-3d;
position:relative;
width:150px;
height:100px;
}
.mian{
width:150px;
height:100px;
position:absolute;
text-align:center;
color:#fff;
background:#ff3efb;
line-height:100px;
font-size:80px;
}
.box{
transition:transform 1s;
}
同上一案例我把图片不一样的数字声明在sum数组里
js
var sum=[1,2,3,4,5,4,3,1,2];
for(var i=0;i<9;i++){
$(‘.box‘).append(‘<div class="mian"></div>‘);
$(‘.mian‘).eq(i).css({‘transform‘:‘rotateY(‘+i*40+‘deg) translateZ(240px)‘,‘background‘:‘url(img/dome06‘+sum[i]+‘.jpg)‘,‘background-size‘:‘100% 100%‘});
}
//上边的for循环是渲染舞台里演员
var x=0;
var y=0;
$(window).keydown(function(event){
var e = event || window.event || arguments.callee.caller.arguments[0];
console.log(e)
if(e && e.keyCode==37){ // 左
y++;
$(‘.box‘).css({‘transform‘:"rotateX("+x*20+"deg) rotateY("+y*40+"deg)"});
}
if(e && e.keyCode==39){ // 右
y--;
$(‘.box‘).css({‘transform‘:"rotateX("+x*20+"deg) rotateY("+y*40+"deg)"});
}
if(e && e.keyCode==38){ // 上
x++;
$(‘.box‘).css({‘transform‘:"rotateX("+x*20+"deg) rotateY("+y*40+"deg)"});
}
if(e && e.keyCode==40){ // 下
x--;
$(‘.box‘).css({‘transform‘:"rotateX("+x*20+"deg) rotateY("+y*40+"deg)"});
}
})
//这段是写按下方向键舞台旋转,上边声明的x,y是舞台的x轴与y轴的角度数,event是记录事件信息的对象,e.keyCode是按下时键盘的键值。
