stats.js显示FPS 0〜2，渲染运动太慢

Question

我是three.js的初学者，也将它用于BIM项目，当我加载〜25mb的gltf文件时，我几乎无法移动整个对象，并且stats.js监视器显示的fps为0〜2，最大值gltf文件：https://github.com/xeolabs/xeogl/tree/master/examples/models/gltf/schependomlaan我在vuejs和>中使用THREE js

//package.json
"stats.js": "^0.17.0",
"three": "^0.109.0",

import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
import { DRACOLoader } from 'three/examples/jsm/loaders/DRACOLoader.js';
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';

this.scene = new THREE.Scene();

this.stats = new Stats();
this.stats.showPanel( 0, 1, 2 ); // 0: fps, 1: ms, 2: mb, 3+: custom
let div = document.createElement('div')
div.appendChild(this.stats.dom)

div.style.position = 'absolute';
div.style.top = 0;
div.style.left = 0;
document.getElementsByClassName('gltfViewer')[0].appendChild( div );
// Camera 
this.camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 1500 );
this.camera.position.set( this.pos, this.pos, this.pos );
// renderer
this.raycaster = new THREE.Raycaster();
this.renderer = new THREE.WebGLRenderer({ canvas: document.getElementById('gltfViewerCanvas'), alpha: false });
this.renderer.setClearColor( 0xefefef );
this.renderer.setPixelRatio( window.devicePixelRatio );
this.renderer.setSize(window.innerWidth, window.innerHeight);
// adding controls

this.controls = new OrbitControls( this.camera, this.renderer.domElement );
this.controls.dampingFactor = 0.1;
this.controls.rotateSpeed = 0.12;
this.controls.enableDamping = true;
this.controls.update();

window.addEventListener('resize', _ => this.render());
this.controls.addEventListener('change', _ => this.render());

// light
var ambientLight = new THREE.AmbientLight( 0xcccccc );
this.scene.add( ambientLight );

var directionalLight = new THREE.DirectionalLight( 0xffffff );
directionalLight.position.set( 0, 1, 1 ).normalize();
this.scene.add( directionalLight );
// loading gltf file

// Instantiate a loader
this.gltfLoader = new GLTFLoader();

// Optional: Provide a DRACOLoader instance to decode compressed mesh data
this.dracoLoader = new DRACOLoader();
this.dracoLoader.setDecoderPath( 'three/examples/js/libs/draco' );
this.gltfLoader.setDRACOLoader( this.dracoLoader );

// Load a glTF resource
this.gltfLoader.load( this.src, this.onGLTFLoaded, this.onGLTFLoading, this.onGLTFLoadingError );
//onGLTFLoaded()
this.scene.add( optimizedGltf.scene );
// gltf.scene.getObjectById(404).visible = false;
this.listGltfObjects(gltf);

this.render();
// render ()

this.renderer.render( this.scene, this.camera );
this.stats.update();
// on mounted component :
animate()
// animate() 
this.stats.begin()
this.render();
this.stats.end();
即使在使用https://github.com/AnalyticalGraphicsInc/gltf-pipeline应用Draco压缩之后，也没有任何变化。

谢谢

我是three.js的初学者，也将其用于BIM项目，当我加载〜25mb的gltf文件时，我几乎无法移动整个对象，并且stats.js监视器在最大gltf文件处显示0〜2的fps：https ：// github ....
