`CSS`----图标`3D`环绕旋转，近大远小效果

CSS----图标3D环绕旋转，近大远小效果

1、先设置图标底部圆环,图片为一张正圆图，给图片外层盒子设置 transform: scaleY(0.25);,将图片效果转为椭圆

代码如下：

  <div class="entry-box">
      <div class="entry-box-content">
        <div class="content-circle">
          <div
            class="circle"
          >div>
        div>
      div>
    div>

  .entry-box {
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0;
    left: 0;
    &-content {
      width: 50vw;
      height: 50vw;
      position: absolute;
      top: calc(50% - 25vw);
      left: 25vw;
      z-index: 1;
         .content-circle {
        width: 100%;
        height: 100%;
        display: flex;
        justify-content: center;
        align-items: center;
        transform: scaleY(0.25);//将背景圆设置为3D效果

        .circle {
          width: 100%;
          height: 100%;
          border-radius: 50%;
          background: url("../../assets/bgImg/circular5.png") no-repeat center center;
          background-size: 100% 100%;
        }
      }
      }
}

效果图

2、给底部圆环添加动画

  .circle {
          width: 100%;
          height: 100%;
          border-radius: 50%;
          background: url("../../assets/bgImg/circular5.png") no-repeat center center;
          background-size: 100% 100%;
          animation: centerRotate 15s linear infinite;
        }

@keyframes centerRotate {
  from {
    transform: rotate(0deg);
  }

  to {
    transform: rotate(360deg);
  }
}

3、引入图标，并渲染到页面

import icon1 from "@/assets/iconImg/GEO终端.png";
import icon2 from "@/assets/iconImg/MF终端.png";
import icon3 from "@/assets/iconImg/pad.png";
import icon4 from "@/assets/iconImg/手机.png";
import icon5 from "@/assets/iconImg/显示器.png";
import icon6 from "@/assets/iconImg/服务器.png";
import icon7 from "@/assets/iconImg/笔记本.png";
import icon8 from "@/assets/iconImg/视频终端.png";

const IconList = [
  { id: 1, iconImg: icon1 },
  { id: 2, iconImg: icon2 },
  { id: 3, iconImg: icon3 },
  { id: 4, iconImg: icon4 },
  { id: 5, iconImg: icon5 },
  { id: 6, iconImg: icon6 },
  { id: 7, iconImg: icon7 },
  { id: 8, iconImg: icon8 },
];

 <div
          :class="['icon', 'icon' + item.id]"
          v-for="item in IconList"
          :key="item.id"
         
        >
          <img :src="item.iconImg" alt="" />
        div>

4、设置每个图标的位置，并给每个图标添加动画

 <div
          :class="['icon', 'icon' + item.id]"
          v-for="item in IconList"
          :key="item.id"
         
        >
          <img :src="item.iconImg" alt="" />
        div>

   .icon {
        width: 6vw;
        height: 6vw;
        position: absolute;
        display: flex;
        justify-content: center;
        align-items: center;

        img {
          width: 120%;
        }

        img:hover {
          width: 140%;
        }
      }     
      .icon1 {
        top: 24vw;
        left: 22vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -4s infinite alternate,
                   turnY 8s cubic-bezier(0.36, 0, 0.64, 1) 0s infinite alternate,
                   turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) 0s infinite alternate;
      }
      .icon2 {
        top: 22.25vw;
        left: 11.25vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -6s infinite alternate,
          turnY 8s cubic-bezier(0.36, 0, 0.64, 1) -2s infinite alternate,
          turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) -2s infinite alternate;
      }
      .icon3 {
        top: 19vw;
        left: 3vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -8s infinite alternate,
          turnY 8s cubic-bezier(0.36, 0, 0.64, 1) -4s infinite alternate,
          turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) -4s infinite alternate;
      }
      .icon4 {
        top: 15.25vw;
        left: 11.25vw;
        animation: turnX  8s cubic-bezier(0.36, 0, 0.64, 1) -10s infinite alternate,
                   turnY  8s cubic-bezier(0.36, 0, 0.64, 1) -6s infinite alternate,
                   turn-self 16s cubic-bezier(0.36, 0, 0.64, 1)-6s infinite alternate;
      }
      .icon5 {
        top: 14.5vw;
        left: 22vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -12s infinite alternate,
          turnY 8s cubic-bezier(0.36, 0, 0.64, 1) -8s infinite alternate,
          turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) -8s infinite alternate;
      }
      .icon6 {
        top: 15.25vw;
        right: 11.25vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -14s infinite alternate,
          turnY 8s cubic-bezier(0.36, 0, 0.64, 1) -10s infinite alternate,
          turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) -10s infinite alternate;
      }
      .icon7 {
        top: 19vw;
        left: 41vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -16s infinite alternate,
          turnY 8s cubic-bezier(0.36, 0, 0.64, 1) -12s infinite alternate,
          turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) -12s infinite alternate;
      }

      .icon8 {
        top: 22.25vw;
        right: 11.25vw;
        animation: turnX 8s cubic-bezier(0.36, 0, 0.64, 1) -18s infinite alternate,
          turnY 8s cubic-bezier(0.36, 0, 0.64, 1) -14s infinite alternate,
          turn-self 16s cubic-bezier(0.36, 0, 0.64, 1) -14s infinite alternate;
      }

1、第一个icon初始值：

turn-self ：duration为 turnX和turnY之和

turnX：delay 为turn-self duration一半

turnY，turn-self ：delay 为 0

2、每个delay 每次递减的值为 turn-self的duration/icon的数量 例子：16/8 = 2，每次递减2；

3、cubic-bezier，css3贝塞尔曲线 一条表示进度变化快慢的速度曲线

/* icon自身的大小缩放 */
@keyframes turn-self {
  0% {
    transform: scale(0.7);
  }

  50% {
    transform: scale(1);
  }

  100% {
    transform: scale(0.7);
  }
}

/* icon横向运动变化，x轴的范围 */
@keyframes turnX {
  0% {
    left: 3vw;
  }

  100% {
    left: 41vw;
  }
}

/*icon纵向运动变化，Y轴的范围 */
@keyframes turnY {
  0% {
    top: 14.5vw;
  }

  100% {
    top: 24vw;
  }
}

效果图：

5、设置鼠标移入移出效果

 <div
          :class="['icon', 'icon' + item.id]"
          v-for="item in IconList"
          :key="item.id"
          :style="`animation-play-state: ${animationPlayState};`"
          @mouseover="mouseOver"
          @mouseleave="mouseleave"
        >

let animationPlayState = ref<string>("");

function mouseOver() {
  animationPlayState.value = "paused";
}
function mouseleave() {
  animationPlayState.value = "running";
}
