output_to_avizo()

template<class C3T3 >

void CGAL::IO::output_to_avizo	(	std::ostream &	os,
		const C3T3 &	c3t3
	)

#include <CGAL/IO/File_avizo.h>

outputs mesh to avizo format

Parameters

os	the stream
c3t3	the mesh complex

Avizo File Format

output_to_medit()

template<class C3T3 >

void CGAL::IO::output_to_medit	(	std::ostream &	os,
		const C3T3 &	c3t3,
		bool	rebind = false,
		bool	show_patches = false
	)

#include <CGAL/IO/File_medit.h>

outputs a mesh complex to the medit (.mesh) file format.

See [12] for a comprehensive description of this file format.

Parameters

os	the output stream
c3t3	the mesh complex
rebind	if set to true, labels of cells are rebinded into [1..nb_of_labels]
show_patches	if set to true, patches are labeled with different labels than cells. If set to false, each surface facet is written twice, using the label of each adjacent cell.

Examples:

Mesh_3/mesh_implicit_domains.cpp, and Mesh_3/mesh_implicit_domains_2.cpp.

output_to_tetgen()

template<class C3T3 >

void CGAL::IO::output_to_tetgen	(	std::string	filename,
		const C3T3 &	c3t3,
		bool	rebind = false,
		bool	show_patches = false
	)

#include <CGAL/IO/File_tetgen.h>

outputs a mesh complex to tetgen format

Parameters

filename	the path to the output file
c3t3	the mesh
rebind	if true, labels of cells are rebinded into [1..nb_of_labels]
show_patches	if true, patches are labeled with different labels than cells. If false, each surface facet is written twice, using label of each adjacent cell.

Tetgen File Format

output_to_vtu()

template<class C3T3 >

void CGAL::IO::output_to_vtu	(	std::ostream &	os,
		const C3T3 &	c3t3,
		IO::Mode	mode = BINARY
	)

#include <CGAL/IO/output_to_vtu.h>

writes a tetrahedron mesh using the UnstructuredGrid XML format.

Template Parameters

C3T3	a model of MeshComplexWithFeatures_3InTriangulation_3.

Parameters

os	the stream used for writing.
c3t3	the instance of C3T3 to be written.
mode	decides if the data should be written in binary (IO::BINARY) or in ASCII (IO::ASCII).

Examples:

Mesh_3/mesh_polyhedral_domain_with_features.cpp.
