◆ facets_in_complex_2_to_triangle_mesh()

template<class C2T3 , class TriangleMesh >
void CGAL::facets_in_complex_2_to_triangle_mesh ( const C2T3 &  c2t3,
TriangleMesh &  graph 
)

#include <CGAL/IO/facets_in_complex_2_to_triangle_mesh.h>

converts a manifold surface reconstructed by make_surface_mesh() to a TriangleMesh.

This function exports the surface as a TriangleMesh and appends it to graph. It must be manifold. For this purpose, you may call make_surface_mesh() with Manifold_tag or Manifold_with_boundary_tag parameter.

Template Parameters
C2T3a model of SurfaceMeshComplex_2InTriangulation_3.
TriangleMesha model of MutableFaceGraph with an internal point property map. The point type should be compatible with the one used in C2T3.
Parameters
c2t3a manifold instance of C2T3.
graphan instance of TriangleMesh.

◆ output_surface_facets_to_off()

template<class SurfaceMeshComplex_2InTriangulation_3 >
bool CGAL::output_surface_facets_to_off ( std::ostream &  os,
const SurfaceMeshComplex_2InTriangulation_3 c2t3,
int  options = Surface_mesher::IO_ORIENT_SURFACE 
)

#include <CGAL/IO/Complex_2_in_triangulation_3_file_writer.h>

writes a manifold or non-manifold surface reconstructed by make_surface_mesh() in the OFF file format.

In case the surface is manifold the triangles can be oriented.

Template Parameters
SurfaceMeshComplex_2InTriangulation_3must be a model of the SurfaceMeshComplex_2InTriangulation_3 concept.
Returns
true if the surface is manifold and orientable.
Parameters
osstream in which to write.
c2t3Input surface.
optionsan int that is the binary union of values of Surface_mesher::IO_option.
Returns
true if the surface could be written to the stream.
