◆ MixBnd() [1/2]

static Handle< Law_BSpFunc > Law::MixBnd ( const Handle< Law_Linear > & Lin )

static

This algorithm searches the knot values corresponding to the splitting of a given B-spline law into several arcs with the same continuity. The continuity order is given at the construction time. Builds a 1d bspline that is near from Lin with null derivatives at the extremities.

◆ MixBnd() [2/2]

static Handle< TColStd_HArray1OfReal > Law::MixBnd	(	const Standard_Integer	Degree,
		const TColStd_Array1OfReal &	Knots,
		const TColStd_Array1OfInteger &	Mults,
		const Handle< Law_Linear > &	Lin
	)

static

Builds the poles of the 1d bspline that is near from Lin with null derivatives at the extremities.

◆ MixTgt()

static Handle< TColStd_HArray1OfReal > Law::MixTgt	(	const Standard_Integer	Degree,
		const TColStd_Array1OfReal &	Knots,
		const TColStd_Array1OfInteger &	Mults,
		const Standard_Boolean	NulOnTheRight,
		const Standard_Integer	Index
	)

static

Builds the poles of the 1d bspline that is null on the rigth side of Knots(Index) (on the left if NulOnTheRight is false) and that is like a t*(1-t)(1-t) curve on the left side of Knots(Index) (on the rigth if NulOnTheRight is false). The result curve is C1 with a derivative equal to 1. at first parameter (-1 at last parameter if NulOnTheRight is false). Warning: Mults(Index) must greater or equal to degree-1.

◆ Reparametrize()

static Handle< Law_BSpline > Law::Reparametrize	(	const Adaptor3d_Curve &	Curve,
		const Standard_Real	First,
		const Standard_Real	Last,
		const Standard_Boolean	HasDF,
		const Standard_Boolean	HasDL,
		const Standard_Real	DFirst,
		const Standard_Real	DLast,
		const Standard_Boolean	Rev,
		const Standard_Integer	NbPoints
	)

static

Computes a 1 d curve to reparametrize a curve. Its an interpolation of NbPoints points calculated at quasi constant abscissa.

◆ Scale()

static Handle< Law_BSpline > Law::Scale	(	const Standard_Real	First,
		const Standard_Real	Last,
		const Standard_Boolean	HasF,
		const Standard_Boolean	HasL,
		const Standard_Real	VFirst,
		const Standard_Real	VLast
	)

static

Computes a 1 d curve to scale a field of tangency. Value is 1. for t = (First+Last)/2 . If HasFirst value for t = First is VFirst (null derivative). If HasLast value for t = Last is VLast (null derivative).
