vue动态粒子背景效果-particles、threejs

一、第一种

使用script标签引入，比较简单方便，但是效果比较单一，而且是在body上的背景，而vue又是单页面应用，所以说一个页面引入后其他页面也会有这个效果

  mounted() {
    const oScript = document.createElement('script');
    oScript.type = 'text/javascript';
    
    oScript.color='	220,20,60'
    oScript.opacity='0.9'
    oScript.src = 'https://cdn.bootcss.com/canvas-nest.js/1.0.1/canvas-nest.min.js';
    document.body.appendChild(oScript);
}

二、第二种

引入particles插件

  页面部分
<div id="particles"  ></div>


js部分
mounted() {
    this.$nextTick(()=>{
       particlesJS.load('particles','../../static/app.json');
    })
}


app.json文件放最后了

三、第三种

引入vue-particles插件

页面部分
<vue-particles
  class="aa"
    color="#292929"
    :particleOpacity="1"
    :particlesNumber="80"
    shapeType="circle"
    :particleSize="2"
    linesColor="#292929"
    :linesWidth="1"
    :lineLinked="true"
    :lineOpacity="0.8"
    :linesDistance="150"
    :moveSpeed="3"
    :hoverEffect="true"
    hoverMode="grab"
    :clickEffect="true"
  >

</vue-particles>


js部分（main文件中）
import VueParticles from 'vue-particles'  
Vue.use(VueParticles)

四、第四种

使用threejs模拟粒子动态效果

ps：app.json文件（第二种）

app.json文件
