jquery图片拼成的3D立方体旋转动画特效代码

使用方法

var trans3DDemo1 = $("#trans3DDemo1"), 
    trans3DBoxes1 = $("#trans3DBoxes1"),// div containing all the the boxes
    boxes1 = $("#trans3DBoxes1 div"), // all the boxes
    threeDTimeline = new TimelineMax({onUpdate:updateCube, repeat:-1}),
	stageW = ($(window).width())/2,
	stageH = ($(window).height())/2,
	stageX = (stageW-(trans3DBoxes1.width()/2)),
	stageY = (stageH-(250/2));
//transformPerspective gives the element its own vanishing point
//perspective allows all the child elements (orange boxes) to share the same vanishing point with each other
//transformStyle:"preserve3d" allows the child elements to maintain their 3D position (noticeable only when their parent div is rotated in 3D space)
TweenMax.set(trans3DBoxes1, {css:{transformPerspective:3000, transformStyle:"preserve-3d"}}); //saves a dozen lines of vendor-prefixed css ;)
/*
K, lets build a cube and place it
boxes1[0] = frontside
boxes1[1] = leftside
boxes1[2] = rightside
boxes1[3] = topside
boxes1[4] = bottomside
boxes1[5] = backside

threeDTimeline.set(boxes1[0], {rotationX:0, rotationY:0, x:0, y:0, z:125, opacity:0.85})
              .set(boxes1[1], {rotationX:0, rotationY:-90, x:-125, y:0, z:0, opacity:0.85})
