Parallel cell-based 3D voronoi tessellations
multivoro is a python library that allows building 3D Voronoi/Laguerre tessellations with voro++ exposed in python via the nanobind library. It leverages the latest multi-threaded extension of Voro++ to allow computing the voronoi cells in parallel.
Codebases
Installation
Wheels
There are available pre-compiled wheels to pip install for Linux and macOS. However, note that these wheels are compiled without multithreading support.
To install them in your system:
pip install multivoroSource
To build multivoro from source in Ubuntu:
Setup a python virtual environment:
# python versions to choose from: [python3.10-python3.14]
sudo apt install python3.10-dev python3.10-venv
python3.10 -mvenv venv
source ./venv/bin/activateInstall openmp runtime and compile the wheel:
sudo apt install libomp-dev
git clone --recurse-submodules https://github.com/eleftherioszisis/multivoro.git
cd multivoro
USE_OpenMP=ON pip install .USE_OpenMP environment variable is used as an option in multivoro cmake. By default it is set to ‘OFF’.
Usage
from multivoro import compute_voronoi
cells = compute_voronoi(
points=[[-1.0, 0.0, 0.0], [1.0, 0.0, 0.0]],
radii=[1.0, 1.0],
limits=[[-2.0, -1.0, -1.0], [2.0, 1.0, 1.0]],
n_threads=6,
)
for cell in cells:
print(cell.get_vertices())
print(cell.get_neighbors())
print(cell.get_face_vertices())Voro++ Copyright And Acknowledgments
