Law Function based on a BSpline curve 1d. Package
methods and classes are implemented in package Law
to construct the basis curve with several
constraints.

Public Member Functions | |
Law_BSpFunc () | |
Law_BSpFunc (const Handle< Law_BSpline > &C, const Standard_Real First, const Standard_Real Last) | |
GeomAbs_Shape | Continuity () const |
Standard_Integer | NbIntervals (const GeomAbs_Shape S) const |
Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S> | |
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_Real | Value (const Standard_Real X) |
Returns the value of the function at the point of parameter X. | |
void | D1 (const Standard_Real X, Standard_Real &F, Standard_Real &D) |
Returns the value F and the first derivative D of the function at the point of parameter X. | |
void | D2 (const Standard_Real X, Standard_Real &F, Standard_Real &D, Standard_Real &D2) |
Returns the value, first and seconde derivatives at parameter X. | |
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. | |
void | Bounds (Standard_Real &PFirst, Standard_Real &PLast) |
Returns the parametric bounds of the function. | |
