A polygon is said to be simple (or a Jordan polygon) if the only points
of the plane belonging to two polygon edges of are the polygon
vertices of .
Such a polygon has a well-defined interior and exterior.
Simple polygons are topologically equivalent to a disk.
The breaking up of self-intersecting polygons into simple polygons (illustrated above) is also called polygon
tessellation (Woo et al. 1999).
