我需要在一些元素上实现“房间”三维旋转;实现它变换：translateX(-100％)rotateY(90deg)和它的相反过渡使用.它在Chrome中运行良好,但在Firefox(最高版本为34)中,元素在转换过程中会闪烁.他们可以暂时这样做,已经走了一半,或完全消失.
我注意到的是：如果父级的透视CSS值高于所讨论元素的计算宽度 – 过渡进展顺利.如果观点真的是罪魁祸首,那么我不理解这种行为的本质;规范说,如果所有点的Z轴值低于透视值,则不绘制元素.在过渡期间,至少应该至少部分可见.
应该注意的是,只有rotateY似乎有问题 – 而不是rorateX.
这是代码示例. html：
<div class="cont">
<div id="bg-club" class="background club"></div>
<div id="bg-cafe" class="background cafe active"></div>
<div id="bg-fitness" class="background fitness"></div>
<div id="bg-resto" class="background resto"></div>
<div id="bg-lady" class="background lady"></div>
</div>
CSS(为方便起见,删除了前缀规则)：
.cont{
position:absolute;
top:0;
right:0;
bottom:0;
left:0;
z-index:1;
overflow:hidden;
perspective:1000px;
transform-style:preserve-3d;
}
.background.active{
visibility:visible;
z-index:1;
}
.background{
position:absolute;
top:50px;
right:50px;
bottom:50px;
left:50px;
z-index:10;
backface-visibility: hidden;
transform: translate3d(0,0);
transform-style: preserve-3d;
visibility:hidden;
overflow:hidden;
background-repeat:no-repeat;
background-position:center center;
background-size:cover;
}
.background.cafe{background-color:#987071;}
.background.club{background-color:#a3367f}
.background.fitness{background-color:#79728b;}
.background.lady{background-color:#a6160e;}
.background.resto{background-color:#712912;}
.rotateRoomLeftOut {
transform-origin: 100% 50%;
animation: rotateRoomLeftOut 4s both ease;
}
.rotateRoomLeftIn {
transform-origin: 0% 50%;
animation: rotateRoomLeftIn 4s both ease;
}
@keyframes rotateRoomLeftOut {
to { opacity: .3; transform: translateX(-100%) rotateY(90deg); }
}
@keyframes rotateRoomLeftIn {
from { opacity: .3; transform: translateX(100%) rotateY(-90deg); }
}
这里是the fiddle.按1-5黄色框我们激活相应的背景动画.这里的透视图是1000px,因此可以通过调整窗口大小来实现不希望的效果.
另一个例子是this great set of page 3D transitions.只需导航到Rotate-> Room-> Room to Left或Right.
编辑
似乎Firefox只使那些元素闪烁,其相应的维度(RotateY的宽度或rotateX的高度)大于父级的透视图.我还没想到,为什么会发生这种情况,但到目前为止最简单,最直接的解决方案是将上述视角设置得大于元素的维度.在我的情况下,对于FF 19或其他方式,它将是100vw(或覆盖两个旋转尺寸的100vmax).
更新的代码段：
$(document).ready(function(){
var generalEvtAffix = '.hotdot',bodyEl = $('body'),pageContents = $('.sidebar,.center-block'),tabsSel = $('.areas [data-toggle="tab"]');
// Анимация фонов на главной
var bgs = $('.background');
$('.areas [data-toggle="tab"]').on('click'+generalEvtAffix,function(event){
event.preventDefault();
var thisLink = $(this);
/* Если уже активен или анимация всё ещё не закончена,ничего не делаем */
if(thisLink.parent().hasClass('active') || bgs.hasClass('animated'))
return;
var bg = $('#bg-'+this.getAttribute('data-bg')),bgActive = $('.background.active');
/* Случайным образом определяем направление анимации. */
var animationDirs = ["Left"/*,"Top","Right","Bottom" */],animationDirection = animationDirs[Math.floor(Math.random() * (animationDirs.length) + 0)];
/* - отключаем клик по ссылке на направлении - чтобы временно заблокировать переключение вкладок */
tabsSel.on('click'+generalEvtAffix+'.clicked',function(e){
e.preventDefault();
return false;
});
bgActive.addClass('animated rotateRoom'+animationDirection+'Out')
.on('animationend.homepage-area-click webkitAnimationEnd.homepage-area-click',function(){

/* По окончании анимации обратно включаем клик. */
console.log(event);
$(this).removeClass('animated rotateRoom'+animationDirection+'In')
.off('animationend.homepage-area-click webkitAnimationEnd.homepage-area-click');;

仍然期待这种行为背后的原因.
解决方法
我相信它闪烁的原因是因为Mozilla正在检测对象是不可见的.
如果你的视角是1000px,宽度为1100px的东西旋转,那么元素的边缘将在你身后传递并离开视图,mozilla可能会将其视为“不渲染”
如果你的视角是1000px,宽度为1100px的东西旋转,那么元素的边缘将在你身后传递并离开视图,mozilla可能会将其视为“不渲染”
我能为一致视图提供的唯一解决方案是将视角设置为100vw,以确保您的视角总是在屏幕宽度范围内
