CGAL 6.0 - CGAL Basic Viewer
|
#include <CGAL/Qt/Basic_viewer.h>
CGAL::QGLViewer.
The class Basic_viewer is a Qt widget based on QGLViewer that allows to visualize 3D elements: points, segments, triangles, rays and lines.
This class stores a reference to a Graphics_scene. Elements are added through the scene. This class 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.
CGAL::QGLViewer is our internal fork of QGLViewer class which is A versatile 3D OpenGL viewer based on QOpenGLWidget.
