Fan triangulation

Fan triangulation is a method used in computational geometry, particularly in the field of computer graphics and geographic information systems. The process involves breaking down a polygon (usually a simple polygon) into a set of triangles, which can be more easily processed in various applications such as rendering or spatial analysis. The distinguishing feature of fan triangulation is that it typically starts from a single vertex (the "fan" vertex) and connects it to all other vertices of the polygon, forming a series of triangles.
