CGAL::Qt_widget_Nef_3<Nef_polyhedron_3>

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.

#include <CGAL/IO/Qt_widget_Nef_3.h>

Parameters

The template parameter expects an instantiation of Nef_polyhedron_3<Traits>.

Creation

Qt_widget_Nef_3<Nef_polyhedron_3> W ( Nef_polyhedron_3 N);
	Creates a widget W for displaying the 3D Nef polyhedron N.

Example

This example reads a 3D Nef polyhedron from standard input and displays it in a Qt widget.
