GeomAdaptor_Curve () | |
GeomAdaptor_Curve (const Handle< Geom_Curve > &C) | |
GeomAdaptor_Curve (const Handle< Geom_Curve > &C, const Standard_Real UFirst, const Standard_Real ULast) | |
ConstructionError is raised if Ufirst>Ulast | |

void | Load (const Handle< Geom_Curve > &C, const Standard_Real UFirst, const Standard_Real ULast) |
ConstructionError is raised if Ufirst>Ulast | |
const Handle_Geom_Curve & | Curve () const |
Provides a curve inherited from Hcurve from Adaptor. This is inherited to provide easy to use constructors. | |
Standard_Real | FirstParameter () const |
Standard_Real | LastParameter () const |
GeomAbs_Shape | Continuity () const |
Standard_Integer | NbIntervals (const GeomAbs_Shape S) |
Returns the number of intervals for continuity <S>. May be one if Continuity(me) >= <S> | |
void | Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) |
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() | |
Handle_Adaptor3d_HCurve | Trim (const Standard_Real First, const Standard_Real Last, const Standard_Real Tol) const |
Returns a curve equivalent of <me> between parameters <First> and <Last>. <Tol> is used to test for 3d points confusion. //! If <First> >= <Last> | |

Computes the point of parameter U. | |
void | D1 (const Standard_Real U, gp_Pnt &P, gp_Vec &V) const |
Computes the point of parameter U on the curve with its first derivative. Warning : On the specific case of BSplineCurve: if the curve is cut in interval of continuity at least C1, the derivatives are computed on the current interval. else the derivatives are computed on the basis curve. | |
void | D2 (const Standard_Real U, gp_Pnt &P, gp_Vec &V1, gp_Vec &V2) const |
Returns the point P of parameter U, the first and second derivatives V1 and V2. Warning : On the specific case of BSplineCurve: if the curve is cut in interval of continuity at least C2, the derivatives are computed on the current interval. else the derivatives are computed on the basis curve. | |
void | D3 (const Standard_Real U, gp_Pnt &P, gp_Vec &V1, gp_Vec &V2, gp_Vec &V3) const |
Returns the point P of parameter U, the first, the second and the third derivative. Warning : On the specific case of BSplineCurve: if the curve is cut in interval of continuity at least C3, the derivatives are computed on the current interval. else the derivatives are computed on the basis curve. | |
gp_Vec | DN (const Standard_Real U, const Standard_Integer N) const |
The returned vector gives the value of the derivative for the order of derivation N. Warning : On the specific case of BSplineCurve: if the curve is cut in interval of continuity CN, the derivatives are computed on the current interval. else the derivatives are computed on the basis curve. //! Raised if N < 1. | |
Standard_Real | Resolution (const Standard_Real R3d) const |
returns the parametric resolution | |
GeomAbs_CurveType | GetType () const |

Standard_Integer | NbPoles () const |
this should NEVER make a copy of the underlying curve to read the relevant information | |
Standard_Integer | NbKnots () const |

Handle_Geom_BSplineCurve | BSpline () const |
this will NOT make a copy of the BSpline Curve : If you want to modify the Curve please make a copy yourself Also it will NOT trim the surface to myFirst/Last. |
