Function Documentation

read_VTP()

template<typename Graph , typename NamedParameters = CGAL::parameters::Default_named_parameters>

bool CGAL::IO::read_VTP	(	const std::string &	fname,
		Graph &	g,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/boost/graph/IO/VTK.h>

reads a PolyData in the VTK (VTU / VTP) File Formats into a triangulated surface mesh.

The data is expected to represent a 2-manifold (possibly with borders).

Attention

The graph g is not cleared, and the data from the file are appended.

Template Parameters

Graph	a model of MutableFaceGraph
NamedParameters	a sequence of Named Parameters

Parameters

fname	the path to the file that will be read
g	the output mesh
np	optional Named Parameters described below

Optional Named Parameters

vertex_point_map a property map associating points to the vertices of g Type: a class model of WritablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type Default: boost::get(CGAL::vertex_point, g) Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in Graph.

Returns

true if reading was successful, false otherwise.

write_VTP() [1/2]

template<typename Graph , typename NamedParameters = CGAL::parameters::Default_named_parameters>

bool CGAL::IO::write_VTP	(	const std::string &	fname,
		const Graph &	g,
		const NamedParameters &	np = parameters::default_values()
	)

#include <CGAL/boost/graph/IO/VTK.h>

writes a triangulated surface mesh the file fname, in the PolyData XML format (VTK (VTU / VTP) File Formats).

Template Parameters

Graph	a model of FaceListGraph
NamedParameters	a sequence of Named Parameters

Parameters

fname	the name of the output file
g	the triangle mesh to be output
np	optional sequence of Named Parameters among the ones listed below

Optional Named Parameters

use_binary_mode indicates whether data should be written in binary (true) or in ASCII (false) Type: Boolean Default: true
vertex_point_map a property map associating points to the vertices of g Type: a class model of ReadablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type Default: boost::get(CGAL::vertex_point, g) Extra: If this parameter is omitted, an internal property map for CGAL::vertex_point_t must be available in Graph.
vertex_index_map a property map associating to each vertex of graph a unique index between 0 and num_vertices(graph) - 1 Type: a class model of ReadablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and std::size_t as value type Default: no vertex indices in the output
stream_precision a parameter used to set the precision (i.e. how many digits are generated) of the output stream Type: int Default: 6

Precondition

g contains only triangular faces

Returns

true if writing was successful, false otherwise.

write_VTP() [2/2]

template<typename Graph , typename NamedParameters = CGAL::parameters::Default_named_parameters>

	)

#include <CGAL/boost/graph/IO/VTK.h>

writes a triangulated surface mesh in the PolyData XML format (VTK (VTU / VTP) File Formats).

Template Parameters

Parameters

os	the output stream
