class SurfCurvConstRadInv from BRepBlend
|
|
|
|
inherits SurfCurvFuncInv from Blend
|
|
|
|
---Purpose: Class used to compute a solution of the
|
|
-- surfRstConstRad problem on a done restriction of the
|
|
-- surface.
|
|
-- The vector <X> used in Value, Values and Derivatives
|
|
-- methods has to be the vector of the parametric
|
|
-- coordinates wguide, wcurv, wrst where wguide is the
|
|
-- parameter on the guide line, wcurv is the parameter on
|
|
-- the curve, wrst is the parameter on the restriction on
|
|
-- the surface.

|
|
---Purpose: Returns in the vector Tolerance the parametric tolerance
|
|
-- for each of the 3 variables;
|
|
-- Tol is the tolerance used in 3d space.
|
|
|

GetBounds(me; InfBound,SupBound: out Vector from math);
|
|
---Purpose: Returns in the vector InfBound the lowest values allowed
|
|
-- for each of the 3 variables.
|
|
-- Returns in the vector SupBound the greatest values allowed
|
|
-- for each of the 3 variables.
|

|
IsSolution(me: in out; Sol: Vector from math; Tol: Real from Standard)
|
|
---Purpose: Returns Standard_True if Sol is a zero of the function.
