Detailed Description

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)
