deferred class CurvPointFuncInv from Blend
|
|
|
|
|
|
---Purpose: Deferred class for a function used to compute a
|
|
-- blending surface between a surface and a curve, using
|
|
-- a guide line. This function is used to find a
|
|
-- solution on a done point of the curve.
|
|
-- The vector <X> used in Value, Values and Derivatives
|
|
-- methods has to be the vector of the parametric
|
|
-- coordinates w, U, V where w is the parameter on the
|
|
-- guide line, U,V are the parametric coordinates of a
|
|
-- point on the partner surface.
|
|
|
|
|
