vue3和threejs单击按钮模型高亮显示

---

一、在组件中引入three.js依赖的文件

import {
   
    EffectComposer } from "three/examples/jsm/postprocessing/EffectComposer.js";
import {
   
    RenderPass } from "three/examples/jsm/postprocessing/RenderPass.js";
import {
   
    OutlinePass } from "three/examples/jsm/postprocessing/OutlinePass.js";
import {
   
    ShaderPass } from "three/examples/jsm/postprocessing/ShaderPass.js";
import {
   
    FXAAShader } from "three/examples/jsm/shaders/FXAAShader.js";

二、在setup函数中定义全局变量

    let composer = null;
    let outlinePsaa = null;
