torch-delaunay 1.0.0rc1

The Delaunay triangulation for PyTorch

Torch Delaunay - The Delaunay triangulation library for PyTorch

This is a fast library for computing Delaunay triangulation of 2-dimensional points.

The implementation is based on a sweep-algorithm, introduced by David Sinclair[^1] and later improved by Volodymyr Agafonkin[^2].

Installation

The library is distributed as PyPI package, to install the package, execute the following command:

pip install torch_delaunay

You can use the torch_delaunay library for a fast computation of Delaunay triangulation for points defined as PyTorch tensors.

Usage

import torch
from torch_delaunay.functional import shull2d

# Compute Delaunay triangulation for randomly-generated 2-dimensional points.
points = torch.rand((100, 2))
simplices = shull2d(simplices)
