Installation

Recommended Environment

The code has been tested in the following environment:

Package	Version	Comment
PyTorch	1.9.0
point_cloud_utils	0.18.0	For evaluation only. It loads meshes to compute point-to-mesh distances.
pytorch3d	0.5.0	For evaluation only. It computes point-to-mesh distances.
pytorch-cluster	1.5.9	We only use fps (farthest point sampling) to merge denoised patches.

Install via Conda (PyTorch 1.9.0 + CUDA 11.1)

conda env create -f env.yml
conda activate mag

Install Manually

conda create --name mag python=3.8
conda activate mag

conda install pytorch==1.9.0 torchvision==0.10.0 cudatoolkit=11.1 -c pytorch -c nvidia

Denoise Regular-Size Point Clouds (≤ 50K Points)

python test_single.py --input_xyz <input_xyz_path> --output_xyz <output_xyz_path>

You may also barely run python test_single.py to see a quick example.

Denoise Large Point Clouds (> 50K Points)

python test_large.py --input_xyz <input_xyz_path> --output_xyz <output_xyz_path>

You may also barely run python test_large.py to see a quick example.

Train

python train.py

Please find tunable parameters in the script.
