The documentation of GGL (Generic Geometry Library) is still scattered
and hard to follow. As usual the first test I do on a library is to
see how well it can be adapted to existing code. GGL seems to be able
to adapt c_arrays and tuples as nD points. I was wondering if
boost::array and fusion::vector can be adapted as well.
The manual says it is but the header file
boost/geometry/geometries/adapted/boost_array_as_ring.hpp
doesn't seem to have that purpose.
In the following example, p4 doesn't work as a point
#include
#include
#include
#include
#include
#include<iostream>
int main(){
using namespace boost::geometry;
point p1(1,2,3);
double p2[3] = {4,5,6};
boost::tuple p3(7,8,9);
boost::array p4={{10,11,12}};
std::clog << distance(p1,p2) << std::endl;
std::clog << distance(p2,p3) << std::endl;
std::clog << distance(p3,p4) << std::endl;
return 0;
}
In other words, why there is not
boost/geometry/geometries/adapted/boost_array_cartesian.hpp
?
And it indeed this adaptation of boost::array is not included in the
library, what steps should I follow to make a boost::array adapted to
GGL?
Thank you,
