29//! The root class for bounded surfaces in 3D space. A
30//! bounded surface is defined by a rectangle in its 2D parametric space, i.e.
31//! - its u parameter, which ranges between two finite
32//! values u0 and u1, referred to as "First u
33//! parameter" and "Last u parameter" respectively, and
34//! - its v parameter, which ranges between two finite
35//! values v0 and v1, referred to as "First v
36//! parameter" and the "Last v parameter" respectively.
37//! The surface is limited by four curves which are the
38//! boundaries of the surface:
39//! - its u0 and u1 isoparametric curves in the u parametric direction, and
40//! - its v0 and v1 isoparametric curves in the v parametric direction.
41//! A bounded surface is finite.
42//! The common behavior of all bounded surfaces is
43//! described by the Geom_Surface class.
44//! The Geom package provides three concrete
45//! implementations of bounded surfaces:
46//! - Geom_BezierSurface,
47//! - Geom_BSplineSurface, and
48//! - Geom_RectangularTrimmedSurface.
49//! The first two of these implement well known
50//! mathematical definitions of complex surfaces, the third
51//! trims a surface using four isoparametric curves, i.e. it
52//! limits the variation of its parameters to a rectangle in
53//! 2D parametric space.
