①、安装依赖
注意：需下载以下版本号的插件
npm install vanta@0.5.24npm install three@0.121.0②、关键代码
height: 100vh 根据屏幕的高度去自适应 展示
<div ref="vantaRef" style="width: 100%; height: 100vh"></div><script>import * as THREE from 'three'//导入样式import BIRDS from 'vanta/src/vanta.birds'//导入动态样式逻辑export default { data() { return {}; }, }, mounted() { this.vantaEffect = BIRDS({ el: this.$refs.vantaRef, THREE: THREE }) // 修改颜色时 cells 需要全大写字母 可生效 VANTA.BIRDS({ el: this.$refs.vantaRef, mouseControls: true, touchControls: true, gyroControls: false, minHeight: 200.0, minWidth: 200.0, scale: 1.0, color1: 14381274, color2: 16443110, }); }, beforeDestroy() { if (this.vantaEffect) { this.vantaEffect.destroy() } },</script>以下为 动态案例： 与官网同步…
本次演示主要
以自定义banner图 为案例，给大家去演示。
