...one of the most highly
regarded and expertly designed C++ library projects in the
world.

Boost.Polygon's rectangle type (boost::polygon::rectangle_data) is adapted to the Boost.Geometry Point Concept.
Boost.Polygon's points (as well as polygons) can be used by Boost.Geometry. The two libraries can therefore be used together. Using a boost::polygon::rectangle_data<...>, algorithms from both Boost.Polygon and Boost.Geometry can be called.
#include <boost/geometry/geometries/adapted/boost_polygon.hpp>
The standard header boost/geometry.hpp
does not include this header.
Shows how to use Boost.Polygon rectangle_data within Boost.Geometry
#include <iostream> #include <boost/geometry.hpp> #include <boost/geometry/geometries/adapted/boost_polygon.hpp> int main() { typedef boost::polygon::rectangle_data<int> rect; rect b = boost::polygon::construct<rect>(1, 2, 3, 4); std::cout << "Area (using Boost.Geometry): " << boost::geometry::area(b) << std::endl; std::cout << "Area (using Boost.Polygon): " << boost::polygon::area(b) << std::endl; return 0; }
Output:
Area (using Boost.Geometry): 4 Area (using Boost.Polygon): 4
