PLY-Rename

A simple Python tool to batch rename .ply files in a folder, changing their prefix and reindexing them sequentially. Useful for datasets with files like soldier_redandblack_0001.ply to rename as square_1.ply, square_2.ply, etc.

Features

• Renames all .ply files in a folder to a new prefix and sequential index
• Shows a preview of the first rename and asks for confirmation
• Uses tqdm for progress display
• Command-line interface with argparse
• Docker support

Usage

With Python

1. Install requirements:

   pip install tqdm

2. Run the script:

   python rename_ply.py /path/to/folder --prefix square

With Docker

1. Build the image:

   docker build -t ply-rename .

2. Run the container (replace /your/ply/folder with your folder path):

   docker run -it --rm -v /your/ply/folder:/data ply-rename /data --prefix square

Example

Given files:

• soldier_redandblack_0001.ply
• soldier_redandblack_0002.ply

After running:

python rename_ply.py /path/to/folder --prefix square

They become:

• square_1.ply
• square_2.ply
