## Functions
template<class Mesh , class GSOptions >
void | CGAL::draw (const Mesh &amesh, const std::vector< Surface_mesh_topology::Path_on_surface< Mesh > > &apaths, const GSOptions &gso)
| opens a new window and draws `amesh`, either a 2D linear cell complex or a model of the FaceGraph concept, plus the paths lying on this mesh given in `apaths`.
template<class Mesh >
void | CGAL::draw (const Mesh &amesh, const std::vector< Surface_mesh_topology::Path_on_surface< Mesh > > &apaths)
| A shortcut to `CGAL::draw(amesh, apaths, Graphics_scene_options_face_graph_with_paths{})`.
template<class Mesh , class GSOptions >
void | CGAL::draw (const Mesh &amesh, std::initializer_list< Path_on_surface< Mesh > > apaths, const GSOptions &gso)
| Same function than draw() but taking the paths from a list instead from an std::vector.

void | CGAL::draw (const Mesh &amesh, std::initializer_list< Path_on_surface< Mesh > > apaths)
| A shortcut to `CGAL::draw(amesh, apaths, Graphics_scene_options_face_graph_with_paths{})`.

void | CGAL::add_to_graphics_scene (const Mesh &amesh, CGAL::Graphics_scene &gs, const GSOptions &gso, const std::vector< Surface_mesh_topology::Path_on_surface< Mesh > > &apaths)
| adds the vertices, edges and faces of `amesh`, either a 2D linear cell complex or a model of the FaceGraph concept, plus the paths lying on this mesh given in `apaths`, into the given graphic scene `gs`.

## Function Documentation

## ◆ add_to_graphics_scene()

template<class Mesh , class GSOptions >

void CGAL::add_to_graphics_scene | ( | const Mesh & | amesh,
|  | CGAL::Graphics_scene & | gs,
|  | const GSOptions & | gso,
|  | const std::vector< Surface_mesh_topology::Path_on_surface< Mesh > > & | apaths
| ) |  |

`#include <CGAL/draw_face_graph_with_paths.h>`

adds the vertices, edges and faces of `amesh`, either a 2D linear cell complex or a model of the FaceGraph concept, plus the paths lying on this mesh given in `apaths`, into the given graphic scene `gs`.

Parameters of the cells are taken from the optional graphics scene options parameter `gso`. Note that `gs` is not cleared before being filled (to enable to draw several data structures in the same basic viewer).

Template Parameters

  Mesh | either a 2D linear cell complex or a model of the FaceGraph concept.
  GSOptions | a model of `GraphicsSceneOptionsFaceGraphWithPaths` concept.

Parameters

  amesh | the mesh to draw.
  gs | the graphic scene to fill.
  gso | the graphics scene options parameter.
  apaths | the paths to draw, which should lie on `amesh`.

## ◆ draw()

template<class Mesh , class GSOptions >

void CGAL::draw | ( | const Mesh & | amesh,
|  | const std::vector< Surface_mesh_topology::Path_on_surface< Mesh > > & | apaths,
|  | const GSOptions & | gso
| ) |  |

`#include <CGAL/draw_face_graph_with_paths.h>`

opens a new window and draws `amesh`, either a 2D linear cell complex or a model of the FaceGraph concept, plus the paths lying on this mesh given in `apaths`.

Parameters of the drawing are taken from the optional graphics scene options parameter.

A call to this function blocks the execution of the program until the drawing window is closed. This function requires `CGAL_Qt6`, and is only available if the macro `CGAL_USE_BASIC_VIEWER` is defined. Linking with the cmake target `CGAL::CGAL_Basic_viewer` will link with `CGAL_Qt6` and add the definition `CGAL_USE_BASIC_VIEWER`.

Template Parameters

  Mesh | either a 2D linear cell complex or a model of the FaceGraph concept.
  GSOptions | a model of `GraphicsSceneOptionsFaceGraphWithPaths` concept.

Parameters

  amesh | the mesh to draw.
  apaths | the paths to draw, which should lie on `amesh`.
  gso | the graphics scene options parameter.
