virtual Handle_GeomFill_TrihedronLaw | Copy () const |
virtual void | SetCurve (const Handle< Adaptor3d_HCurve > &C) |
virtual void | SetInterval (const Standard_Real First, const Standard_Real Last) |
Sets the bounds of the parametric interval on the function This determines the derivatives in these values if the function is not Cn. | |
virtual Standard_Boolean | D0 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &Normal, gp_Vec &BiNormal) |
compute Triedrhon on curve at parameter | |
virtual Standard_Boolean | D1 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &DTangent, gp_Vec &Normal, gp_Vec &DNormal, gp_Vec &BiNormal, gp_Vec &DBiNormal) |
compute Triedrhon and derivative Trihedron on curve at parameter Warning : It used only for C1 or C2 aproximation | |
virtual Standard_Boolean | D2 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &DTangent, gp_Vec &D2Tangent, gp_Vec &Normal, gp_Vec &DNormal, gp_Vec &D2Normal, gp_Vec &BiNormal, gp_Vec &DBiNormal, gp_Vec &D2BiNormal) |
compute Trihedron on curve first and seconde derivatives. Warning : It used only for C2 aproximation | |
virtual Standard_Integer | NbIntervals (const GeomAbs_Shape S) const |
Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S> | |
virtual 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() | |
virtual void | GetAverageLaw (gp_Vec &ATangent, gp_Vec &ANormal, gp_Vec &ABiNormal) |
