//! Describes the common behavior of surfaces which <br>
//! have a simple parametric equation in a local <br>
//! coordinate system. The Geom package provides <br>
//! several implementations of concrete elementary surfaces: <br>
//! - the plane, and <br>
//! - four simple surfaces of revolution: the cylinder, the <br>
//! cone, the sphere and the torus. <br>
//! An elementary surface inherits the common behavior <br>
//! of Geom_Surface surfaces. Furthermore, it is located <br>
//! in 3D space by a coordinate system (a gp_Ax3 <br>
//! object) which is also its local coordinate system. <br>
//! Any elementary surface is oriented, i.e. the normal <br>
//! vector is always defined, and gives the same <br>
//! orientation to the surface, at any point on the surface. <br>
//! In topology this property is referred to as the "outside <br>
//! region of the surface". This orientation is related to <br>
//! the two parametric directions of the surface. <br>
//! Rotation of a surface around the "main Axis" of its <br>
//! coordinate system, in the trigonometric sense given <br>
//! by the "X Direction" and the "Y Direction" of the <br>
//! coordinate system, defines the u parametric direction <br>
//! of that elementary surface of revolution. This is the <br>
//! default construction mode. <br>
//! It is also possible, however, to change the orientation <br>
//! of a surface by reversing one of the two parametric <br>
//! directions: use the UReverse or VReverse functions <br>
//! to change the orientation of the normal at any point on the surface. <br>
//! Warning <br>
//! The local coordinate system of an elementary surface <br>
//! is not necessarily direct: <br>
//! - if it is direct, the trigonometric sense defined by its <br>
//! "main Direction" is the same as the trigonometric <br>
//! sense defined by its two vectors "X Direction" and "Y Direction": <br>
//! "main Direction" = "X Direction" ^ "Y Direction" <br>
//! - if it is indirect, the two definitions of trigonometric <br>
//! sense are opposite: <br>
//! "main Direction" = - "X Direction" ^ "Y Direction" <br>
