21 ---Purpose: Class used to compute a solution of the
22 -- surfRstConstRad problem on a done restriction of the
23 -- surface.
24 -- The vector <X> used in Value, Values and Derivatives
25 -- methods has to be the vector of the parametric
26 -- coordinates wguide, wcurv, wrst where wguide is the
27 -- parameter on the guide line, wcurv is the parameter on
28 -- the curve, wrst is the parameter on the restriction on
29 -- the surface.
