WebThe class Polygon_with_holes_2 models the concept GeneralPolygonWithHoles_2. It represents a linear polygon with holes. It is parameterized with two types ( Kernel and Container) that are used to instantiate the type Polygon_2 < Kernel, Container >. The latter is used to represents the outer boundary and the boundary of the holes (if any exist). WebA polygon must also be non-self-intersecting. Multipolygons are merely a list of polygons bundled together, but the structure of each consituent polygon in the list follows the same structure as for a single 'stand-alone' polygon. So, The interior rings of the constituent polygons of a multipolygon are also holes. ray white port hedland south hedland
