*
* \brief This class manage the OpenGL scene where the plots will be rendered.
*
* Plotter3D provides an agnostic way to manage a 3d scene for draw math plots,
* Contains just OpenGL calls, so is uncoupled with QWidget nor QtQuick. This
* class needs the PlotsModel (to create the geometry for 3D plots) and also
* exposes some methods to change the scene (like hide/show the axis or
* reference planes for example)
