本文实例为大家分享了微信小程序实现3D轮播图效果的具体代码，供大家参考，具体内容如下

首先上一下效果图：

在做的时候首先想到的是用swiper组件但是发现swiper组件放进去图片的时候会没有3d的效果，原因是swiper组件自带的style属性限制了3d效果所需要的属性，所以单独写了一个组件。

index.html

<view class='page-con'>
  rotate.wxml
  <view class='stage'>
    <view class='wrapper' bindtouchstart='start' bindtouchend='end'>
      <block wx:for='{{swiperList}}'>
        <image class='imgBasic {{index === 0 "" : "fold"}} {{item.active ""}}' src='{{item.imgsrc}}' data-index='{{index}}'></image>
      </block>
    </view>
    <view class='dots'>
      <block wx:for='{{swiperList}}' wx:key='unique'>
        <view data-i='{{index}}' bindtap='fn' class='dot {{index === currentImageIndex "active" : ""}}'></view>
      </block>
    </view>
  </view>
</view>

现在的功能是左滑移动，感兴趣的朋友可以试试右滑移动。
