What is self.pos_xyz(xyz)

[songtianhui]

Hello, thanks for your work!
I am reading the code but get confused about some details.
In the class Point_Transformer_Last, the self.pos_xyz is not defined in the section.
What does the operation specifically do and where can I find the definition of it?
Appreciate!

It means that we considers the input coordinates in the middle layer, and we found it can play a good role in preventing overfitting on modelnet40.

Thanks for reply!
But what I do wonder is where can I find the implemention (source code) of the method self.pos_xyz(). It seems that there is no definition of it in the project.
