## Dependencies

The code was tested on Ubuntu 20.04 LTS and Windows 10, but should also run on MacOSX without issues.

The project runs on `python3` and the following packages: `matplotlib numpy numba scipy skimage opencv-python`. First, please make sure that `python3` and `pip` are installed. On linux:

```shell
sudo apt-get install python3 python3-pip
```

The dependencies can then be installed by running the `install-deps.py` file, or by installing them manually via pip:

```shell
python3 -m pip install matplotlib numpy numba scipy scikit-image opencv-python
```

The illumination precomputation can be done on the GPU if you have CUDA installed and configured. See `conditions.py` for this.

## Running the project

Running `run.py` executes the project and generates output figures in `resources/tautavel_J/visu`.

The interactive 3D visualization of the result is not included in this repository.
