CGAL 多面体頂点の x、y、z 値にアクセスしたいと考えています。
私が見つけた最も近いコードはこれです
// polyhedron_prog_tetra.C
// -----------------------------------------------------------
#include <CGAL/Cartesian.h>
#include <iostream>
#include <CGAL/Halfedge_data_structure_polyhedron_default_3.h>
#include <CGAL/Polyhedron_default_traits_3.h>
#include <CGAL/Polyhedron_3.h>
typedef CGAL::Cartesian<double> R;
typedef CGAL::Halfedge_data_structure_polyhedron_default_3<R> HDS;
typedef CGAL::Polyhedron_default_traits_3<R> Traits;
typedef CGAL::Polyhedron_3<Traits,HDS> Polyhedron;
typedef Polyhedron::Point Point;
typedef Polyhedron::Vertex_iterator Vertex_iterator;
int main() {
Point p( 1.0, 0.0, 0.0);
Point q( 0.0, 1.0, 0.0);
Point r( 0.0, 0.0, 1.0);
Point s( 0.0, 0.0, 0.0);
Polyhedron P;
P.make_tetrahedron( p, q, r, s);
CGAL::set_ascii_mode( std::cout);
Vertex_iterator begin = P.vertices_begin();
for ( ; begin != P.vertices_end(); ++begin)
std::cout << "(" << begin->point() << ") ";
std::cout << std::endl;
return 0;
}
But when I try and compile I get a errors
/usr/lib/freecad/Mod/OpenSCAD/CGAL/CallCGAL.cpp:60: error: expected initializer before ‘<’ token
/usr/lib/freecad/Mod/OpenSCAD/CGAL/CallCGAL.cpp:61: error: expected initializer before ‘<’ token
