vue 3d轮播图上下拖拽飞屏效果

要实现这样的效果，需要使用Vue.js和一些CSS和JavaScript技巧。以下是一种实现方式：

1. 首先，创建一个Vue组件，包含一个3D轮播图和一些CSS样式，用于让轮播图旋转和显示。

<template>
  <div class="carousel-container">
    <div class="carousel">
      <div class="slide" v-for="(item, index) in items" :key="index">
        <img :src="item.image" alt="slide" class="slide-image">
        <div class="slide-content">
          <h3 class="slide-title">{{ item.title }}</h3>
          <p class="slide-text">{{ item.text }}</p>
        </div>
      </div>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: [
        {
          image: "https://picsum.photos/400/300",
          title: "Slide 1",
          text: "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
        },
        {
          image: "https://picsum.photos/400/300",
          title: "Slide 2",
          text: "Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."
        },
        {
          image: "https://picsum.photos/400/300",
          title: "Slide 3",
          text: "Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
        }
      ]
    };
  }
};
</script>

<style scoped>
.carousel-container {
  position: relative;
  width: 100%;
  height: 400px;
  overflow: hidden;
}

.carousel {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  width: 80%;
  height: 80%;
  transform-style: preserve-3d;
  transform: translateZ(-1000px);
  animation: rotate 15s linear infinite;
}

.slide {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  width: 400px;
  height: 300px;
  border-radius: 10px;
  box-shadow: 0px 0px 20px rgba(0, 0, 0, 0.5);
  transform-style: preserve-3d;
  backface-visibility: hidden;
}

.slide-image {
  width: 100%;
  height: 100%;
  object-fit: cover;
  border-radius: 10px;
}

.slide-content {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
  padding: 20px;
  background-color: rgba(0, 0, 0, 0.5);
  color: #fff;
  text-align: center;
}

.slide-title {
  font-size: 32px;
  margin-bottom: 10px;
}

.slide-text {
  font-size: 18px;
}
</style>

2. 使用CSS和JavaScript添加拖拽飞屏效果。在组件的mounted生命周期钩子中，添加以下代码：

mounted() {
  let startX, startY, currentX, currentY, distanceX, distanceY, isDragging = false;
  const carousel = this.$el.querySelector(".carousel");

  carousel.addEventListener("mousedown", e => {
    startX = e.clientX;
    startY = e.clientY;
    isDragging = true;
    carousel.style.animation = "none";
  });

  carousel.addEventListener("mousemove", e => {
    if (!isDragging) return;
    e.preventDefault();
    currentX = e.clientX;
    currentY = e.clientY;
    distanceX = currentX - startX;
    distanceY = currentY - startY;
    carousel.style.transform = `translateX(${distanceX}px) translateY(${distanceY}px) translateZ(-1000px) rotateY(${distanceX / 10}deg) rotateX(${distanceY / 10}deg)`;
  });

  carousel.addEventListener("mouseup", e => {
    isDragging = false;
    carousel.style.animation = "rotate 15s linear infinite";
    carousel.style.transform = `translateZ(-1000px)`;
  });

  carousel.addEventListener("mouseleave", e => {
    isDragging = false;
    carousel.style.animation = "rotate 15s linear infinite";
    carousel.style.transform = `translateZ(-1000px)`;
  });
}

这段代码监听轮播图的mousedown、mousemove、mouseup和mouseleave事件，在鼠标按下时记录起始坐标，移动时根据坐标计算移动距离，并将轮播图的transform样式设置为相应的位移和旋转角度。在鼠标抬起或离开轮播图时，将轮播图的transform样式重置，并重新启动旋转动画。

这样就实现了一个Vue 3D轮播图上下拖拽飞屏效果。
