21 | ---Purpose: Function of reframing between a restriction surface of the |
22 | -- surface and a curve. |
23 | -- Class used to compute a solution of the |
7fd59977 |
24 | -- surfRstConstRad problem on a done restriction of the |
25 | -- surface. |
26 | -- The vector <X> used in Value, Values and Derivatives |
27 | -- methods has to be the vector of the parametric |
28 | -- coordinates wguide, wcurv, wrst where wguide is the |
29 | -- parameter on the guide line, wcurv is the parameter on |
30 | -- the curve, wrst is the parameter on the restriction on |
31 | -- the surface. |
