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.

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.
