assign_values (3 coordinate values)

Assign three values to a geometry (usually a 3D point)

Synopsis

template<typename Geometry, typename Type>
void assign_values(Geometry & geometry, Type const & c1, Type const & c2,
                   Type const & c3)

Parameters

Type	Concept	Name	Description
Geometry &	Any type fulfilling a Geometry Concept	geometry	A model of the specified concept
Type const &	numerical type (int, double, ttmath, ...) to specify the coordinates	c1	First coordinate (usually x-coordinate)
Type const &	numerical type (int, double, ttmath, ...) to specify the coordinates	c2	Second coordinate (usually y-coordinate)
Type const &	numerical type (int, double, ttmath, ...) to specify the coordinates	c3	Third coordinate (usually z-coordinate)

Header

Either

#include <boost/geometry.hpp>

#include <boost/geometry/algorithms/assign.hpp>

Example

Use assign to set three coordinates of a 3D point

#include <iostream>
#include <iomanip>

#include <boost/geometry.hpp>
#include <boost/geometry/geometries/point.hpp>

int main()
{
    boost::geometry::model::point<double, 3, boost::geometry::cs::cartesian> p;
    boost::geometry::assign_values(p, 1.2345, 2.3456, 3.4567);

    std::cout << boost::geometry::dsv(p) << std::endl;

    return 0;
}

Output:

(1.2345, 2.3456, 3.4567)
