The script for downloading and preparing the point clouds are from PointCNN repository https://github.com/yangyanli/PointCNN[](https://github.com/yangyanli/PointCNN).
python3 ./download_datasets.py -d shapenet_partseg -f path_to_directory
python3 ./prepare_partseg_data.py -f path_to_shapenet_partseg
python shapenet_seg.py --rootdir path_to_data_dir --savedir path_to_save_dir --npoints 2500
python shapenet_seg.py --rootdir path_to_data_dir --savedir path_to_save_dir --npoints 2500 --test
You can also use the --ply flag to generate PLY file for result visualization.
The previous command line is result with one spatial tree. To test with multiple spatial trees, use the --ntree flag:
python shapenet_seg.py --rootdir path_to_data_dir --savedir path_to_save_dir --npoints 2500 --test --ntree 4
