deferred class BoundedSurface from Geom inherits Surface from Geom
---Purpose : The root class for bounded surfaces in 3D space. A
-- bounded surface is defined by a rectangle in its 2D parametric space, i.e.
-- - its u parameter, which ranges between two finite
-- values u0 and u1, referred to as "First u
-- parameter" and "Last u parameter" respectively, and
-- - its v parameter, which ranges between two finite
-- values v0 and v1, referred to as "First v
-- parameter" and the "Last v parameter" respectively.
-- The surface is limited by four curves which are the
-- boundaries of the surface:
-- - its u0 and u1 isoparametric curves in the u parametric direction, and
-- - its v0 and v1 isoparametric curves in the v parametric direction.
-- A bounded surface is finite.
-- The common behavior of all bounded surfaces is
-- described by the Geom_Surface class.
-- The Geom package provides three concrete
-- implementations of bounded surfaces:
-- - Geom_BezierSurface,
-- - Geom_BSplineSurface, and
-- - Geom_RectangularTrimmedSurface.
-- The first two of these implement well known
-- mathematical definitions of complex surfaces, the third
-- trims a surface using four isoparametric curves, i.e. it
-- limits the variation of its parameters to a rectangle in
-- 2D parametric space.
