Public Member Functions | |
Standard_EXPORT | Law_Linear () |
Constructs an empty linear evolution law. . | |
Standard_EXPORT void | Set (const Standard_Real Pdeb, const Standard_Real Valdeb, const Standard_Real Pfin, const Standard_Real Valfin) |
Defines this linear evolution law by assigning both: - the bounds Pdeb and Pfin of the parameter, and - the values Valdeb and Valfin of the function at these two parametric bounds. . | |
Standard_EXPORT GeomAbs_Shape | Continuity () const |
Returns GeomAbs_CN . | |
Standard_EXPORT Standard_Integer | NbIntervals (const GeomAbs_Shape S) const |
Returns 1 . | |
Standard_EXPORT void | Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const |
Stores in <t> the parameters bounding the intervals of continuity <s>. The array must provide enough room to accomodate for the parameters. i.e. T.Length() > NbIntervals() . | |
Standard_EXPORT Standard_Real | Value (const Standard_Real X) |
Returns the value of this function at the point of parameter X. . | |
Standard_EXPORT void | D1 (const Standard_Real X, Standard_Real &F, Standard_Real &D) |
Returns the value F and the first derivative D of this function at the point of parameter X. . | |
Standard_EXPORT void | D2 (const Standard_Real X, Standard_Real &F, Standard_Real &D, Standard_Real &D2) |
Returns the value, first and second derivatives at parameter X. . | |
Standard_EXPORT Handle_Law_Function | Trim (const Standard_Real PFirst, const Standard_Real PLast, const Standard_Real Tol) const |
Returns a law equivalent of <me> between parameters <first> and <last>. <tol> is used to test for 3d points confusion. It is usfule to determines the derivatives in these values <first> and <last> if the Law is not Cn. . | |
Standard_EXPORT void | Bounds (Standard_Real &PFirst, Standard_Real &PLast) |
Returns the parametric bounds of the function. . | |
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const |
