I tryed to use MeshBuilder.AddPolygon to draw a concave polygon and it does not work as expected. In fact the method uses a TriangleFan in case of more than 4 points. That is ok if the polygon is convex but does not work in the other cases.
I think Delaunay triangulation is something that can be used in this case.
Is it implemented in the toolkit?
Does exists any work around?
