Function Documentation

◆ add_to_graphics_scene()

template<class CT2 , class InDomainPMap >

void CGAL::add_to_graphics_scene	(	const CT2 &	ct2,
		InDomainPMap	ipm,
		CGAL::Graphics_scene &	gs
	)

#include <CGAL/draw_constrained_triangulation_2.h>

adds the vertices, edges and faces of ct2 into the given graphic scene gs.

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. Note that gs is not cleared before being filled (to enable to draw several data structures in the same basic viewer).

Template Parameters

CT2	which must be an instantiation of a `CGAL::Constrained_triangulation_2<...>`.
InDomainPMap	a class model of `ReadablePropertyMap` with `CT2::Face_handle` as key type and `bool` as value type.

Parameters

ct2	the constrained triangulation to draw.
ipm	the property map defining the faces which are in the domain.
gs	the graphic scene to fill.

Advanced

The real declaration of this function template is:

template<class Gt, class Tds, class Itag, class InDomainPMap>

void CGAL::add_to_graphics_scene(const CGAL::Constrained_triangulation_2<Gt, Tds, Itag>& ct2, InDomainPMap ipm, CGAL::Graphics_scene& gs);

◆ draw()

template<class CT2 , class InDomainPMap >

void CGAL::draw	(	const CT2 &	ct2,
		InDomainPMap	ipm
	)

#include <CGAL/draw_constrained_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 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.
