Function Documentation

◆ draw() [1/2]

template<class T2 >
void CGAL::draw ( const T2 &  at2)

#include <CGAL/draw_triangulation_2.h>

opens a new window and draws a triangulation.

If the triangulation has constraints they are drawn. If the face type has a member function bool is_in_domain() the faces inside and outside of the domain are drawn in different colors.

A call to this function is blocking, that is the program continues as soon as the user closes the window. This function requires CGAL_Qt5, 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_Qt5 and add the definition CGAL_USE_BASIC_VIEWER.

Template Parameters
T2a triangulation class derived from Triangulation_2 or Constrained_triangulation_2
Parameters
at2the triangulation to draw.

◆ draw() [2/2]

template<class CT2 , class InDomainPMap >
void CGAL::draw ( const CT2 &  act2,
InDomainPMap  ipm 
)

#include <CGAL/draw_triangulation_2.h>

opens a new window and draws a constrained triangulation.

If the triangulation has constraints they are drawn. The faces inside and outside of the domain, based on the property map, are drawn in different colors.

A call to this function is blocking, that is the program continues as soon as the user closes the window. This function requires CGAL_Qt5, 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_Qt5 and add the definition CGAL_USE_BASIC_VIEWER.

Template Parameters
CT2a triangulation class derived from Constrained_triangulation_2
InDomainPMapa class model of ReadWritePropertyMap with CT::Face_handle as key type and bool as value type.
Parameters
act2the constrained triangulation to draw.
ipmthe property map defining the faces which are in the domain.
