CGAL::Qt_widget_Nef_S2< Nef_polyhedron_S2 > Class Template Reference

#include <CGAL/IO/Qt_widget_Nef_S2.h>

Definition

The class Qt_widget_Nef_S2 uses the OpenGL interface of Qt in order to display a Nef_polyhedron_S2.

Its purpose is to provide an easy to use viewer for Nef_polyhedron_S2. There are no means provided to enhance the functionality of the viewer.

In addition to the functions inherited from the Qt class QGLWidget, Qt_widget_Nef_S2 only has a single public constructor. For the usage of Qt_widget_Nef_S2 see the example below.

Parameters

The template parameter expects an instantiation of Nef_polyhedron_S2<Traits>.

See Also

CGAL::Nef_polyhedron_S2<Traits>

Example

This example creates some random Sphere_segments and distributes them on two Nef_polyhedron_2. The two Nef polyhedra are combined by a symmetric difference and the result is displayed in a Qt widget.
