PyNIF3D

License: MIT Read the Docs

PyNIF3D is an open-source PyTorch-based library for research on neural implicit functions (NIF)-based 3D geometry representation. It aims to accelerate research by providing a modular design that allows for easy extension and combination of NIF-related components, as well as readily available paper implementations and dataset loaders.

As of August 2021, the following implementations are supported:

Installation

To get started with PyNIF3D, you can use pip to install a copy of this repository on your local machine or build the provided Dockerfile.

Local Installation

pip install --user "https://github.com/pfnet/pynif3d.git"

The following packages need to be installed in order to ensure the proper functioning of all the PyNIF3D features:

  • torch_scatter>=1.3.0
  • torchsearchsorted>=1.0

A script has been provided to take care of the installation steps for you. Please download it to a directory of choice and run:

bash post_install.bash

Docker Build

Enabling CUDA Support

Please make sure the following dependencies are installed in order to build the Docker image with CUDA support:

  • nvidia-docker
  • nvidia-container-runtime

Then register the nvidia runtime by adding the following to /etc/docker/daemon.json:

{
    "runtimes": {
        "nvidia": {
            [...]
        }
    },
    "default-runtime": "nvidia"
}

Restart the Docker daemon:

sudo systemctl restart docker

You should now be able to build a Docker image with CUDA support.

Building Dockerfile

git clone https://github.com/pfnet/pynif3d.git
cd pynif3d && nvidia-docker build -t pynif3d .

Running the Container

nvidia-docker run -it pynif3d bash
