Function Documentation

◆ add_to_graphics_scene()

template<typename GeometryTraits_2 , typename Dcel , typename GSOptions >
void CGAL::add_to_graphics_scene ( const Arrangement_2< GeometryTraits_2, Dcel > &  arr,
CGAL::Graphics_scene &  gs,
const GSOptions &  gso 
)

#include <CGAL/draw_arrangement_2.h>

adds the vertices, edges and faces of arr 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
GeometryTraits_2a geometry traits type, a model of a 2D arrangement traits concept. At this point it must be an instance of either CGAL::Arr_segment_traits_2 or CGAL::Arr_conic_traits_2.
Dcelthe DCEL type, a model of the ArrangementDcel concept.
GSOptionsa model of GraphicsSceneOptions concept.
Parameters
arrthe 2D arrangement to draw.
gsthe graphic scene to fill.
gsothe graphics scene options parameter.

◆ draw()

template<typename GeometryTraits_2 , typename Dcel , typename GSOptions >
void CGAL::draw ( const Arrangement_2< GeometryTraits_2, Dcel > &  arr,
const GSOptions &  gso 
)

#include <CGAL/draw_arrangement_2.h>

opens a new window and draws arr, an instance of the CGAL::Arrangement_2 class template.

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
GeometryTraits_2a geometry traits type, a model of a 2D arrangement traits concept. At this point it must be an instance of either CGAL::Arr_segment_traits_2 or CGAL::Arr_conic_traits_2.
Dcelthe DCEL type, a model of the ArrangementDcel concept.
GSOptionsa model of GraphicsSceneOptions concept.
Parameters
arrthe 2D arrangement to draw.
gsothe graphics scene options parameter.
