Geometry |
Any type fulfilling a Geometry Concept |

Must be specified |
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) |
The constructed geometry, here: a 3D point
Either
#include <boost/geometry.hpp>
Or
#include <boost/geometry/algorithms/make.hpp>
Using make to construct a three dimensional point
#include <iostream> #include <boost/geometry.hpp> #include <boost/geometry/geometries/point.hpp> int main() { typedef boost::geometry::model::point<double, 3, boost::geometry::cs::cartesian> point_type; point_type p = boost::geometry::make<point_type>(1, 2, 3); std::cout << boost::geometry::dsv(p) << std::endl; return 0; }
Output:
(1, 2, 3)
