0025 //! The root class for bounded surfaces in 3D space. A
0026 //! bounded surface is defined by a rectangle in its 2D parametric space, i.e.
0027 //! - its u parameter, which ranges between two finite
0028 //! values u0 and u1, referred to as "First u
0029 //! parameter" and "Last u parameter" respectively, and
0030 //! - its v parameter, which ranges between two finite
0031 //! values v0 and v1, referred to as "First v
0032 //! parameter" and the "Last v parameter" respectively.
0033 //! The surface is limited by four curves which are the
0034 //! boundaries of the surface:
0035 //! - its u0 and u1 isoparametric curves in the u parametric direction, and
0036 //! - its v0 and v1 isoparametric curves in the v parametric direction.
0037 //! A bounded surface is finite.
0038 //! The common behavior of all bounded surfaces is
0039 //! described by the Geom_Surface class.
0040 //! The Geom package provides three concrete
0041 //! implementations of bounded surfaces:
0042 //! - Geom_BezierSurface,
0043 //! - Geom_BSplineSurface, and
0044 //! - Geom_RectangularTrimmedSurface.
0045 //! The first two of these implement well known
0046 //! mathematical definitions of complex surfaces, the third
0047 //! trims a surface using four isoparametric curves, i.e. it
0048 //! limits the variation of its parameters to a rectangle in
0049 //! 2D parametric space.
