33//! Deferred class for a function used to compute a
34//! blending surface between a surface and a curve, using
35//! a guide line. This function is used to find a
36//! solution on a done point of the curve.
37//!
38//! The vector <X> used in Value, Values and Derivatives
39//! methods has to be the vector of the parametric
40//! coordinates w, U, V where w is the parameter on the
41//! guide line, U,V are the parametric coordinates of a
42//! point on the partner surface.
