- Subject: [cgal-discuss] CGAL-Bindings (Python): Mesh_3 examples
- Date: Thu, 21 May 2015 02:21:52 -0700
Hi folks, is there a cgal-python-bindings implementation for Mesh_3 examples, particularly http://doc.cgal.org/latest/Mesh_3/Mesh_3_2mesh_3D_image_8cpp-example.html? I've been trying to get started on it but it seems that not all classes are exposed via swig,
Exact_predicates_inexact_constructions_kernel
and Mesh_Domain
have to be defined but are not part of the CGAL.CGAL_Mesh_3
module. Thank you.mesh_3D_image.cpp:
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Mesh_triangulation_3.h>
#include <CGAL/Mesh_complex_3_in_triangulation_3.h>
#include <CGAL/Mesh_criteria_3.h>
#include <CGAL/Labeled_image_mesh_domain_3.h>
#include <CGAL/make_mesh_3.h>
#include <CGAL/Image_3.h>
// Domain
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef CGAL::Labeled_image_mesh_domain_3<CGAL::Image_3,K> Mesh_domain;
// Triangulation
#ifdef CGAL_CONCURRENT_MESH_3
typedef CGAL::Mesh_triangulation_3<
Mesh_domain,
CGAL::Kernel_traits<Mesh_domain>::Kernel, // Same as sequential
CGAL::Parallel_tag // Tag to activate parallelism
>::type Tr;
#else
typedef CGAL::Mesh_triangulation_3<Mesh_domain>::type Tr;
#endif
typedef CGAL::Mesh_complex_3_in_triangulation_3<Tr> C3t3;
// Criteria
typedef CGAL::Mesh_criteria_3<Tr> Mesh_criteria;
// To avoid verbose function and named parameters call
using namespace CGAL::parameters;
int main()
{
// Loads image
CGAL::Image_3 image;
image.read("data/liver.inr.gz");
// Domain
Mesh_domain domain(image);
// Mesh criteria
Mesh_criteria criteria(facet_angle=30, facet_size=6, facet_distance=4,
cell_radius_edge_ratio=3, cell_size=8);
// Meshing
C3t3 c3t3 = CGAL::make_mesh_3<C3t3>(domain, criteria);
// Output
std::ofstream medit_file("out.mesh");
c3t3.output_to_medit(medit_file);
return 0;
}
