How to use vue-3d-loader

If use in global, insert code in entry file：

/* vue2 */
import vue3dLoader from "vue-3d-loader";
Vue.use(vue3dLoader);

/* vue3 */
import vue3dLoader from "vue-3d-loader";
createApp(App).use(vue3dLoader).mount("#app");

If non-global use, insert code in your vue files:

import { vue3dLoader } from "vue-3d-loader"; // The vue3dLoader in {...}

Use tags in your components<vue3dLoader></vue3dLoader>

<vue3dLoader
  :height="200"
  :showFps="true"
  :filePath="['/fbx/1.fbx', '/obj/2.obj', '/gltf/3.gltf']"
  :mtlPath="[null, '/obj/2.mtl', null]"
  :backgroundColor="0xff00ff"
></vue3dLoader>

8. Loader draco model

Need to download Draco repository storage with local static folder of your project, download url: https://github.com/king2088/vue-3d-loader/blob/master/public/assets/draco.7z

<template>
  <vue3dLoader
    filePath="/models/gltf/LittlestTokyo.glb"
