## Function Documentation

## ◆ read_GOCAD() [1/2]

template<typename PointRange , typename PolygonRange , typename NamedParameters = CGAL::parameters::Default_named_parameters>

bool CGAL::IO::read_GOCAD | ( | const std::string & | fname,
|  | PointRange & | points,
|  | PolygonRange & | polygons,
|  | const NamedParameters & | np = `parameters::default_values()`
| ) |  |

`#include <CGAL/IO/GOCAD.h>`

reads the content of the file `fname` into `points` and `polygons`, using the GOCAD (TS) File Format.

Attention
  The polygon soup is not cleared, and the data from the file are appended.

Template Parameters

  PointRange | a model of the concepts `RandomAccessContainer` and `BackInsertionSequence` whose value type is the point type
  PolygonRange | a model of the concepts `SequenceContainer` 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`
  NamedParameters | a sequence of Named Parameters

Parameters

  fname | the path to the input file
  points | points of the soup of polygons
  polygons | a range of polygons. Each element in it describes a polygon using the indices of the points in `points`.
  np | optional 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.

## ◆ read_GOCAD() [2/2]

template<typename PointRange , typename PolygonRange , typename NamedParameters = CGAL::parameters::Default_named_parameters>

|  | PolygonRange & | polygons,
|  | const NamedParameters & | np = `parameters::default_values()`
| ) |  |

`#include <CGAL/IO/GOCAD.h>`

reads the content of `is` into `points` and `polygons`, using the GOCAD (TS) File Format.

Attention
  The polygon soup is not cleared, and the data from the stream are appended.

Template Parameters

  PointRange | a model of the concepts `RandomAccessContainer` and `BackInsertionSequence` whose value type is the point type
  PolygonRange | a model of the concepts `SequenceContainer` 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`
  NamedParameters | a sequence of Named Parameters

Parameters

  is | the input stream
  points | points of the soup of polygons
  polygons | a range of polygons. Each element in it describes a polygon using the indices of the points in `points`.
  np | optional 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.

|  | const PolygonRange & | polygons,
|  | const NamedParameters & | np = `parameters::default_values()`
| ) |  |

`#include <CGAL/IO/GOCAD.h>`

writes the content of `points` and `polygons` in `fname`, using the GOCAD (TS) File Format.

Template Parameters

  PointRange | a model of the concept `RandomAccessContainer` whose value type is the point type
  PolygonRange | a model of the concept `SequenceContainer` whose `value_type` is itself a model of the concept `SequenceContainer` whose `value_type` is an unsigned integer type convertible to `std::size_t`
  NamedParameters | a sequence of Named Parameters

Parameters

  fname | the path to the output file
  points | points of the soup of polygons
  polygons | a range of polygons. Each element in it describes a polygon using the indices of the points in `points`.
  np | optional sequence of Named Parameters among the ones listed below

Optional Named Parameters

  a parameter used to set the precision (i.e. how many digits are generated) of the output stream Type: int Default: `6` |

Returns
  `true` if the writing was successful, `false` otherwise.
