CGAL 5.6.1  2D Conforming Triangulations and Meshes

In addition to the stream extraction and insertion operators for CGAL 2D triangulations, the following functions can be used.
Functions  
template<class CDT >  
void  CGAL::IO::write_VTU (std::ostream &os, const CDT &tr, IO::Mode mode=IO::BINARY) 
writes the faces of a domain and its constrained edges embedded in a 2D constrained Delaunay triangulation using the PolyData XML format. More...  
template<class CDT , typename InDomainPmap >  
void  CGAL::IO::write_VTU (std::ostream &os, const CDT &tr, InDomainPmap ipm, IO::Mode mode=IO::BINARY) 
writes the faces of a domain and its constrained edges embedded in a 2D constrained Delaunay triangulation using the PolyData XML format. More...  
void CGAL::IO::write_VTU  (  std::ostream &  os, 
const CDT &  tr,  
IO::Mode  mode = IO::BINARY 

) 
#include <CGAL/IO/write_VTU.h>
writes the faces of a domain and its constrained edges embedded in a 2D constrained Delaunay triangulation using the PolyData
XML format.
The faces output are those for which DelaunayMeshFaceBase_2::is_in_domain()
returns true
, the edges are those for which ConstrainedTriangulationFaceBase_2::is_constrained()
returns true
.
CDT  a Constrained_Delaunay_triangulation_2 with face type model of DelaunayMeshFaceBase_2 . 
os  the stream used for writing. 
tr  the triangulated domain to be written. 
mode  decides if the data should be written in binary (BINARY ) or in ASCII (ASCII ). 
void CGAL::IO::write_VTU  (  std::ostream &  os, 
const CDT &  tr,  
InDomainPmap  ipm,  
IO::Mode  mode = IO::BINARY 

) 
#include <CGAL/IO/write_VTU.h>
writes the faces of a domain and its constrained edges embedded in a 2D constrained Delaunay triangulation using the PolyData
XML format.
The faces output are those for which get(ipm, f)
returns true
where f
is a CDT::Face_handle
, the edges are those for which ConstrainedTriangulationFaceBase_2::is_constrained()
returns true
.
CDT  a Constrained_Delaunay_triangulation_2 with face type model of DelaunayMeshFaceBase_2 . 
InDomainPmap  a class model of ReadWritePropertyMap with CDT::Face_handle as key type and bool as value type. 
os  the stream used for writing. 
tr  the triangulated domain to be written. 
ipm  the property map storing if a face is in the domain. 
mode  decides if the data should be written in binary (BINARY ) or in ASCII (ASCII ).
