Polygon Concept

Description

The Polygon Concept describes the requirements for a polygon type. All algorithms in Boost.Geometry will check any geometry arguments against the concept requirements.

A polygon is A polygon is a planar surface defined by one exterior boundary and zero or more interior boundaries. (opengeospatial).

So the definition of a Boost.Geometry polygon differs a bit from e.g. Wiki, where a polygon does not have holes. A polygon of Boost.Geometry is a polygon with or without holes. (A polygon without holes is a helper geometry within Boost.Geometry, and referred to as a ring.)

Concept Definition

The Polygon Concept is defined as following:
