Here's an example: ```c# using System.Collections.Generic; using TriangleNet; using TriangleNet.Geometry; using TriangleNet.Meshing; using TriangleNet.Meshing.Iterators; public class Issue48 { public static void Test() { var poly = new Polygon(6); // Outer...

Another option: add extra points around borehole points before triangulation. Of course you must make sure that those extra points do not introduce any unwanted features. Additionally, you could subdivide...

Are there by any chance duplicate vertices in your input? Please check with PolygonValidator and also take a look at the log.

That's strange. Can you post the full stack trace and maybe a small, but complete (code and input data) test case that reproduces the error?

Ok, I see the problem. Take a look at the [VertexCirculator](https://github.com/wo80/Triangle.NET/blob/master/src/Triangle/Meshing/Iterators/VertexCirculator.cs#L23). It relies on the internal [Vertex.tri](https://github.com/wo80/Triangle.NET/blob/master/src/Triangle/Geometry/Vertex.cs#L24). This means you cannot do ```c# var vert = new Vertex(pt.X, pt.Y, indexer);...

I don't think it's worth worrying about that. The first thing you could try is converting to wav format and 11025 Hz mono. Then compare the fingerprints of that wav...
