read_polygon_mesh()

template<typename PolygonMesh , typename NamedParameters >

bool CGAL::Polygon_mesh_processing::IO::read_polygon_mesh	(	const std::string &	fname,
		PolygonMesh &	g,
		const NamedParameters &	np
	)

#include <CGAL/Polygon_mesh_processing/IO/polygon_mesh_io.h>

reads the file as a polygon soup, repairs, and orients it as to obtain a polygon mesh.

Supported file formats are the following:

• Object File Format (OFF) (.off)
• Wavefront Advanced Visualizer Object Format (OBJ) (.obj)
• STereoLithography (STL) File Format (.stl)
• Polygon File Format (PLY) (.ply)
• GOCAD (TS) File Format (.ts)
• VTK (VTU / VTP) File Formats (.vtp)

The format is detected from the filename extension (letter case is not important).

Template Parameters

PolygonMesh	a model of MutableFaceGraph
NamedParameters	a sequence of Named Parameters

Parameters

fname	the name of the input file
g	the polygon mesh
np	sequence of Named Parameters among the ones listed 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<PolygonMesh>::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 PolygonMesh.
repair_polygon_soup a parameter used indicate whether CGAL::Polygon_mesh_processing::repair_polygon_soup() should be called on the intermediate polygon soup. Type: Boolean Default: true
verbose whether extra information is printed when an incident occurs during reading Type: Boolean Default: false

Returns

true if the reading, repairing, and orientation operations were successful, false otherwise.
