◆ read_OFF() [1/2]

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

#include <CGAL/IO/OFF.h>

reads the content of the file fname into points and polygons, using the Object File Format (OFF).

Template Parameters
PointRangea model of the concept RandomAccessContainer whose value type is the point type
PolygonRangea model of the concepts SequenceContainer and BackInsertionSequence whose value_type is itself a model of the concept SequenceContainer and BackInsertionSequence whose value_type is an unsigned integer type convertible to std::size_t
NamedParametersa sequence of Named Parameters
Parameters
fnamethe path to the input file
pointspoints of the soup of polygons
polygonsa range of polygons. Each element in it describes a polygon using the indices of the points in points.
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 the reading was successful, false otherwise.
