|
//! 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.
