CGAL::Qt_widget_Nef_3< Nef_polyhedron_3 > Class Template Reference

#include <CGAL/IO/Qt_widget_Nef_3.h>

Definition

The class Qt_widget_Nef_3 uses the OpenGL interface of Qt to display a Nef_polyhedron_3.

Its purpose is to provide an easy to use viewer for Nef_polyhedron_3. There are no means provided to enhance the functionality of the viewer.

In addition to the functions inherited from the Qt class OGLWidget via, Qt_widget_Nef_3 only has a single public constructor. For the usage of Qt_widget_Nef_3 see the example below.
