How to register a structure in nested show()

Hey there,

as I can read, there is the possibility to do a nested show. That means one can call the ps::show() function a second time. Now I don't seem to understand what I need to do in order to register strutures in the second show. As an example I currently have the following code

`

 def callback():
   

    if psim.Button("Show"):
    
      ps.show()
      ms = pymeshlab.MeshSet()
      ms.load_new_mesh(os.getcwd()+"/Experiment-78/Experiment-78+curvature.ply")
      vertices = ms.current_mesh().vertex_matrix()
      faces = ms.current_mesh().face_matrix()
      ps.set_invoke_user_callback_for_nested_show(True)
      ps.register_surface_mesh("first mesh", vertices, faces)

(This example is in python but the structure is sufficiently similar). Currently when I press the button the surface mesh is registered in the first show. What do I need to do in order to get it in the second show?

(I am happy about a solution in either C++ or python)

I hope you get what I mean

Bắt đầu bằng cách truy vết các điểm vào ps::show(), ps.set_invoke_user_callback_for_nested_show() và ps.register_surface_mesh() bằng ví dụ callback được cung cấp. Xác nhận chuỗi đăng ký bắt buộc cho một lần hiển thị lồng nhau, sau đó kiểm tra rằng việc nhấn “Show” sẽ hiển thị surface mesh trong lần hiển thị thứ hai.
