Member Function Documentation

 void Law_BSpFunc::Bounds ( Standard_Real & PFirst, Standard_Real & PLast )
virtual

Returns the parametric bounds of the function.

Implements Law_Function.

virtual

Implements Law_Function.

 Handle< Law_BSpline > Law_BSpFunc::Curve ( ) const
 void Law_BSpFunc::D1 ( const Standard_Real X, Standard_Real & F, Standard_Real & D )
virtual

Returns the value F and the first derivative D of the function at the point of parameter X.

Implements Law_Function.

 void Law_BSpFunc::D2 ( const Standard_Real X, Standard_Real & F, Standard_Real & D, Standard_Real & D2 )
virtual

Returns the value, first and seconde derivatives at parameter X.

Implements Law_Function.

 void Law_BSpFunc::Intervals ( TColStd_Array1OfReal & T, const GeomAbs_Shape S ) 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.

Implements Law_Function.

 Standard_Real Law_BSpFunc::Value ( const Standard_Real X )
virtual

Returns the value of the function at the point of parameter X.

Implements Law_Function.
