Delaunator C#

Fast Delaunay triangulation of 2D points implemented in C#.

This code was ported from Mapbox's Delaunator project (JavaScript).

Documentation

See https://mapbox.github.io/delaunator/ for more information about the Triangles and Halfedges data structures.

Unity Installation

Simply edit manifest.json file in your Unity Packages directory

{
  "dependencies": {
    "com.nol1fe.delaunator": "https://github.com/nol1fe/delaunator-sharp.git?path=DelaunatorSharp.Unity",
}

Unity Example

From UnityPackage Menager select Delaunator and press "Import into Project".

Burst Triangulator (optional)

For Unity developers seeking even greater performance and advanced triangulation capabilities, consider exploring BurstTriangulator.

Built with Unity's Burst compiler, it offers lightning-fast triangulation, making it ideal for large datasets and real-time applications.

WPF Example

There is available playground in DelaunatorSharp.WPF.Example project that shows examples of drawing Voronoi Diagram, Delaunay triangulation and Convex Hull

Points were generated with Poisson Disc Sampling implemented by UniformPoissonDiskSampler
