In GMSH, a volume (3D) is defined by its surfaces, a surface (2D) by its (closed) curves and a curve (1D) by its endpoints. Each of these, Volume, Surface, Curve and Point are named elementary entities in GMSH. The first one that is studied here are the 0D entity: Point. They are defined as follows.
