19 | inherits SurfCurvFuncInv from Blend |
20 | |
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. |
