主要讲述封装一个3D轮播相册的组件，效果图如下，仅仅传入一个图片的数组即可，效果如下：
使用Vue3技术开发，支持传入任意张数的图片。
使用方法
<template><Swiper :list="list" />
</template><script setup>
import Swiper from '@/components/Swiper.vue'let list = ['https://gd-hbimg.huaban.com/0c89e8d8eebbd8b3168051c9c32dda927b11041544c27-7h2Nuu_fw658webp','https://gd-hbimg.huaban.com/d8ab30b96c90ef2c0428376d1df6e86df379ddc33b598-XfLbgw_fw658webp','https://gd-hbimg.huaban.com/617a23ff457a8e7f403560601ee1986f0be521ce31262-yudWdl_fw658webp','https://gd-hbimg.huaban.com/02381538312ca44802a7fb6140fdf79711d046d01e256-bGN4Hq_fw658webp','https://gd-hbimg.huaban.com/2f625b869a53f799fdaf79c20ca7e0d96277767b39594-OQN9F9_fw658webp',
]
</script>swiper组件
<template><section><div class="green-circle"><div class="pink-circle"><imgclass="bottom-circle"src="https://gd-hbimg.huaban.com/1784343fe17d90f4de4bccf96594d0965c616f5947463-umfPH3_fw658webp"alt=""/></div></div><div class="swiper-box" id="swiperBox"><divv-for="(item, index) in list":key="'img-' + index"class="loop-item":style="{transform: `translate(-50%, -50%) rotate(${(360 / list.length) * index}deg) translateY(-17.5vh) rotateX(90deg)`,}"><img class="alarm-img" :src="item" /></div></div></section>
</template><script setup>
const props = defineProps({list: {type: Array,default: () => [],},
})
</script><style lang="scss" scoped>

}@keyframes three-dimensions-circle {0% {transform: rotateX(-108deg) rotate(0);}100% {transform: rotateX(-108deg) rotate(-360deg);}
}
</style>1. 大致思路
通过 :style=“{transform: translate(-50%, -50%) rotate(${(360 / list.length) * index}deg) translateY(-17.5vh) rotateX(90deg)}” 来先实现静态的图片摆放，然后通过旋转 swiper-box 来达到整体旋转的效果。
通过 360 / list.length 来计算出每张图片的左右间距，以保证占满一个圈。
2. 3D效果
3D效果主要通过 css3 的 transform-style: preserve-3d; 配合 transform: rotate; 来实现
