\ingroup PkgDrawPointSet3D
opens a new window and draws `aps`, an instance of the `CGAL::Point_set_3` class. A call to this function is blocking, that is the program continues as soon as the user closes the window. This function requires `CGAL_Qt5`, 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_Qt5` and add the definition `CGAL_USE_BASIC_VIEWER`.
\tparam PS an instance of the `CGAL::Point_set_3` class.
\param aps the point set to draw.
