vue-3d-model

vue-3d-model - npm

GitHub - hujiulong/vue-3d-model: 📷 vue.js 3D model viewer component

通过该插件降低Threejs的使用难度

vue项目加载三维模型，我把模型放在了服务器的tomcat里面，需要对tomcat的fbx项目文件夹设置跨域，如下：

vue项目要注意版本

# 默认安装 "vue-3d-model": "^1.4.1", 只支持vue2
npm i vue-3d-model
# vue3 需要安装2版本，vite只建立在vue3之上的，因此vite也是需要安装2版本
npm i vue-3d-model@v2.0.0-alpha.4 --save
