Setup

Install envoriment:

We recommand using Anaconda to set the envoriment, once Anacodna in installed, run the following command.

conda create --name CSGStumpNet python=3.7
conda activate CSGStumpNet
conda install pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=10.1 -c pytorch
conda install -c open3d-admin open3d=0.9
conda install numpy
conda install pymcubes
conda install tensorboard
conda install scipy
pip install tqdm

Datasets and pre-trained weights

Dataset

You can use the pre-prepared dataset from OccNet(consider citing them), you can download the data by

mkdir data
cd data
wget https://s3.eu-central-1.amazonaws.com/avg-projects/occupancy_networks/data/dataset_small_v1.1.zip
unzip dataset_small_v1.1.zip

If you want to prepare data yourself (maybe you want to generate the watertight mesh etc.), please refer to this link.

Pre-Train Weights

Please download pre-trained weights from this google drive

Evaluate using pre-trian weights

python eval.py --config_path ./configs/plane.json

Train from stratch

python train.py --config_path ./configs/plane.json

Evaluation

python metrics.py --config_path ./configs/plane.json
