Build Tests openupm

A single-file package which provides Delaunay triangulation of the given set of points with constraints and mesh refinement.

✨ Supported Features

To view the documentation for the manual and scripting API access it online here or navigate to Documentation~/ and build this using docfx.json.

📐 Example results

As an illustrative example, we present the triangulation of Lake Superior with various refinement parameters. The top-left image shows the result without any refinement.

⏱️ Benchmark

The package utilizes the Burst compiler, which generates highly optimized native code using LLVM. Below, you'll find a performance comparison for classic Delaunay triangulation (without refinement or constraints). between this package and a few alternatives:

🚀 Quick start

Install the package and add using in your code

using andywiecko.BurstTriangulator;

and to triangulate unit box $[(0, 0), (1, 0), (1, 1), (0, 1)]$:

using var positions = new NativeArray<double2>(new[]
{
    new(0, 0), new(1, 0), new(1, 1), new(0, 1)
}, Allocator.Persistent);
using var triangulator = new Triangulator(Allocator.Persistent)
{
    Input = { Positions = positions }
};

triangulator.Run();

var triangles = triangulator.Output.Triangles;
