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，而stats.js监视器在最大gltf文件中显示0~2的fps：https：/ /github.com/xeolabs/xeogl/tree/master/examples/models/gltf/schependomlaan 我使用三个 js和vuejs

// 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()
this.stats.begin()
this.render();
this.stats.end();
即使在使用https://github.com/AnalyticalGraphicsInc/gltf-pipeline应用 Draco 压缩后，也没有任何变化。
