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