Haze Triangulator is a small Unity tool which helps transforming 2D convex and concave non-self-intersecting polygons into collections of triangles which can be made into a Unity mesh to display. The tool allows creating clockwise and counterclockwise triangles so that faces can be selectively front-facing or back-facing depending on the geometry needed.
Download the Unity package from the latest release on GitHub, or simply place the file Triangulator.cs into your project's Assets folder.
To triangulate a 2D path, add using Haze; at the top of your code file, and call the static function Triangulator.Triangulate(), passing a List<Vector2> representing your vertices (this assumes the last vertex to be connected to the first, closing off the polygon; no two line segments of the polygon should intersect; the polygon can be either clockwise or counterclockwise). This will return a List<Triangulator.Triangle> which can then either be read through and operated upon by your code, or simply fed into Triangulator.AddTrianglesToMesh() to convert the triangles to a mesh (or add them to a pre-existing mesh).
For more information about the available functionality and how to use, please refer to the documentation included in the code.
