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 right 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 right 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).

1. _ _/ _ __/ __ /
   VFirst ____/
   VLast ____ First Last

ScaleCub()

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