Question

我如何确定何时加载模型以获得有关加载进度的定期更新，以便我可以构建加载图标。我已经跟踪了我能找到的每个turorial，但是每个回答的onProgress方法只在加载完成后才会触发一次。

我在打字稿中的加载程序代码：

// Load manager
private manager = new THREE.LoadingManager();

// Set up loading manager (in constructor of class)
this.manager.onProgress = function ( item, loaded, total ) {
  console.log( item, loaded, total );
};


// Load OBJ File from Server
private loadFile(path) {
   let loader = new THREE.OBJLoader(this.manager)
   loader.load(path, (obj)=>{
      this.model = obj;
      this.boundingBox = new THREE.BoxHelper(obj)
      this.scene.add(this.model);
   });
}

日志：

http://localhost:5000/api/file/largeModels/z3.obj 1 1

我只在加载了模型后得到这一个日志。我该如何解决这个问题？

请尝试以下代码。

from Tkinter import *
master = Tk()

info=[  ['sue', 1, 'Argentina', 'Bsc'],
    ['peggy-sue', 17, 'U.K.', 'Bsc'],
    ['susie', 234, 'France', 'BA'] 
]

listbox = Listbox(master, width=60)
listbox.pack()

listbox.insert(END, "{:<15s}  {:>5s}  {:<25s}  {:<5s}".format("Name","id","Nationality","Qual") )

for i  in range(len(info)):
    item = "{:<15s}  {:>5d}  {:<25s}  {:<5s}".format(info[i][0],info[i][1],info[i][2],info[i][3])
    print item  # Gives nicely formatted lines
    listbox.insert(END, item)  #Lines are not nicely formatted in listbox

mainloop()

THREE.JS Loader onProgress仅在加载完成后触发一次
