Build your own dataset to train "shape_diffusion"

Hello author, I want to build my own dataset for training.
I observed that watertight_and_sampling.py can build a dataset used to train shape_autoencoder;distributed_render.sh can build a dataset used to train ig2mv; but the dataset construction script for shape_diffusion does not seem to be provided. Is it convenient to provide this part of the script code? Thank you very much.
