Boost.Polygon's point_data

The Boost.Polygon point type (boost::polygon::point_data) is adapted to the Boost.Geometry Point Concept.

Description

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::point_data<...>, algorithms from both Boost.Polygon and Boost.Geometry can be called.

Model of

Point Concept

Header

#include <boost/geometry/geometries/adapted/boost_polygon.hpp>

The standard header boost/geometry.hpp does not include this header.

Example

Shows how to use Boost.Polygon points within Boost.Geometry

#include <iostream>
#include <boost/geometry.hpp>
#include <boost/geometry/geometries/adapted/boost_polygon.hpp>

int main()
{
    boost::polygon::point_data<int> a(1, 2), b(3, 4);
    std::cout << "Distance (using Boost.Geometry): "
        << boost::geometry::distance(a, b) << std::endl;
    std::cout << "Distance (using Boost.Polygon): "
        << boost::polygon::euclidean_distance(a, b) << std::endl;

    return 0;
}

Output:

Distance (using Boost.Geometry): 2.82843
Distance (using Boost.Polygon): 2.82843
