◆ 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).
