I/O Functions

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.
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.

Function Documentation

write_VTU() [1/2]

template<class CDT , typename InDomainPmap >

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.

Template Parameters

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.

Parameters

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).

write_VTU() [2/2]

template<class CDT >

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.

Template Parameters

CDT	a Constrained_Delaunay_triangulation_2 with face type model of DelaunayMeshFaceBase_2.

Parameters

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).
