Implement in own C# project

[Pixel-95]

Is there any beginner tutorial, how to use this library in my own C# project?

Not that I'm aware of. The only pieces of documentation are examples that are linked at the bottom of the readme (which are from the original release).

This is a very ugly method for getting things started.

public Mesh Mesh(List<Vector3> p, List<List<Vector3>> h)
    {
        // Create geometry.
        TriangleNet.Geometry.Polygon polygon = new TriangleNet.Geometry.Polygon();
        List<TriangleNet.Geometry.Vertex> v = new List<Vertex>();

        foreach(Vector3 v3 in p)
        {
            v.Add(new TriangleNet.Geometry.Vertex(
                    (double)v3.x,
                    (double)v3.z));
        }
        polygon.Add(new TriangleNet.Geometry.Contour(v.ToArray()));

        foreach(List<Vector3> hole in h)
        {
            List<TriangleNet.Geometry.Vertex> vh = new List<Vertex>();
            foreach(Vector3 v3 in hole)
            {
                vh.Add(new TriangleNet.Geometry.Vertex(
                        (double)v3.x,
                        (double)v3.z));//, marker));
            }
            polygon.Add(new TriangleNet.Geometry.Contour(vh.ToArray()), true);
        }
        IMesh triangulatedMesh = polygon.Triangulate();

        // Counts.
        int vertexCount = triangulatedMesh.Vertices.Count;

        // Mesh store.
        Vector3[] _vertices = new Vector3[vertexCount];
        Vector2[] _uv = new Vector2[vertexCount];
        List<int> _triangles = new List<int>(); // Size may vary

        // Vertices.
        int index = 0;
        foreach(TriangleNet.Geometry.Vertex eachVertex in triangulatedMesh.Vertices)
        {
            _vertices[index] = new Vector3(
                (float)eachVertex.x,
                0,
                (float)eachVertex.y
            );

            _uv[index] = _vertices[index];

            index++;
        }

        // Triangles.
        foreach(TriangleNet.Topology.Triangle eachTriangle in triangulatedMesh.Triangles)
        {
            // Get vertices.
            Point P2 = eachTriangle.GetVertex(2);
            Point P1 = eachTriangle.GetVertex(1);
            Point P0 = eachTriangle.GetVertex(0);

            // Add only if centroid contained.
            //if(this_.ContainsPoint(centroid) || skipCentroidTest)
            {
                _triangles.Add(P2.ID);
                _triangles.Add(P1.ID);
                _triangles.Add(P0.ID);
            }
        }

        // Create / setup mesh.
        Mesh mesh = new Mesh();
        mesh.vertices = _vertices;
        mesh.uv = _uv;
        mesh.SetTriangles(_triangles.ToArray(), 0);
        mesh.RecalculateNormals();
        return mesh;
    }
