1. Place all the data in the following structure, and there are 130 scenes in total.
|-- transcg
    |-- scene1/
    |-- scene2/
    |-- ... ...
    |-- scene130/
    |
    |-- models
    |   |-- 0-bottle1.ply               # Model of object 0 (bottle1)
    |   |-- 1-bottle2.ply               # Model of object 1 (bottle2)
    |   |-- ... ...

2. Detail structure of each scene (take scene1 as an example)
