Function Documentation

◆ read_polygon_soup()

template<typename PointRange , typename PolygonRange , typename NamedParameters = CGAL::parameters::Default_named_parameters>
bool CGAL::IO::read_polygon_soup ( const std::string &  fname,
PointRange &  points,
PolygonRange &  polygons,
const NamedParameters &  np = parameters::default_values() 
)

#include <CGAL/IO/polygon_soup_io.h>

reads a polygon soup from a file.

Supported file formats are the following:

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

Template Parameters
PointRangea model of the concept RandomAccessContainer whose value type is the point type.
PolygonRangea model of the concepts RandomAccessContainer and BackInsertionSequence whose value_type is itself a model of the concepts RandomAccessContainer and BackInsertionSequence whose value_type is an unsigned integer type convertible to std::size_t
NamedParametersa sequence of Named Parameters
Parameters
fnamethe name of the file.
pointspoints of the soup of polygons
polygonseach element in the range describes a polygon using the indices of the vertices.
npoptional Named Parameters described below
Optional Named Parameters
  • indicates whether output warnings and error messages should be printed or not.
  • Type: Boolean
  • Default: false
Returns
true if reading was successful, false otherwise.
