static Standard_EXPORT Handle_Geom_Curve | To3d (const gp_Ax2 &Position, const Handle(Geom2d_Curve)&Curve2d) |
Computes the curve 3d from package Geom corresponding to curve 2d from package Geom2d, on the plan defined with the local coordinate system Position. . | |
static Standard_EXPORT Handle_Geom2d_Curve | GTransform (const Handle(Geom2d_Curve)&Curve, const gp_GTrsf2d >rsf) |
Computes the curve 3d from package Geom corresponding to the curve 3d from package Geom, transformed with the transformation <gtrsf> WARNING : this method may return a null Handle if it's impossible to compute the transformation of a curve. It's not implemented when : 1) the curve is an infinite parabola or hyperbola 2) the curve is an offsetcurve . | |
static Standard_EXPORT void | SameRange (const Standard_Real Tolerance, const Handle(Geom2d_Curve)&Curve2dPtr, const Standard_Real First, const Standard_Real Last, const Standard_Real RequestedFirst, const Standard_Real RequestedLast, Handle(Geom2d_Curve)&NewCurve2dPtr) |
Make the curve Curve2dPtr have the imposed range First to List the most economic way, that is if it can change the range without changing the nature of the curve it will try to do that. Otherwise it will produce a Bspline curve that has the required range . | |
static Standard_EXPORT void | BuildCurve3d (const Standard_Real Tolerance, Adaptor3d_CurveOnSurface &CurvePtr, const Standard_Real FirstParameter, const Standard_Real LastParameter, Handle(Geom_Curve)&NewCurvePtr, Standard_Real &MaxDeviation, Standard_Real &AverageDeviation, const GeomAbs_Shape Continuity=GeomAbs_C1, const Standard_Integer MaxDegree=14, const Standard_Integer MaxSegment=30) |
static Standard_EXPORT void | AdjustExtremity (Handle(Geom_BoundedCurve)&Curve, const gp_Pnt &P1, const gp_Pnt &P2, const gp_Vec &T1, const gp_Vec &T2) |
static Standard_EXPORT void | ExtendCurveToPoint (Handle(Geom_BoundedCurve)&Curve, const gp_Pnt &Point, const Standard_Integer Cont, const Standard_Boolean After) |
Extends the bounded curve Curve to the point Point. The extension is built: - at the end of the curve if After equals true, or - at the beginning of the curve if After equals false. The extension is performed according to a degree of continuity equal to Cont, which in its turn must be equal to 1, 2 or 3. This function converts the bounded curve Curve into a BSpline curve. Warning - Nothing is done, and Curve is not modified if Cont is not equal to 1, 2 or 3. - It is recommended that the extension should not be too large with respect to the size of the bounded curve Curve: Point must not be located too far from one of the extremities of Curve. . | |
static Standard_EXPORT void | ExtendSurfByLength (Handle(Geom_BoundedSurface)&Surf, const Standard_Real Length, const Standard_Integer Cont, const Standard_Boolean InU, const Standard_Boolean After) |
Extends the bounded surface Surf along one of its boundaries. The chord length of the extension is equal to Length. The direction of the extension is given as: - the u parametric direction of Surf, if InU equals true, or - the v parametric direction of Surf, if InU equals false. In this parametric direction, the extension is built on the side of: - the last parameter of Surf, if After equals true, or - the first parameter of Surf, if After equals false. The extension is performed according to a degree of continuity equal to Cont, which in its turn must be equal to 1, 2 or 3. This function converts the bounded surface Surf into a BSpline surface. Warning - Nothing is done, and Surf is not modified if Cont is not equal to 1, 2 or 3. - It is recommended that Length, the size of the extension should not be too large with respect to the size of the bounded surface Surf. - Surf must not be a periodic BSpline surface in the parametric direction corresponding to the direction of extension. . | |
static Standard_EXPORT void | AxeOfInertia (const TColgp_Array1OfPnt &Points, gp_Ax2 &Axe, Standard_Boolean &IsSingular, const Standard_Real Tol=1.0e-7) |
Compute axes of inertia, of some points -- -- -- <axe>.Location() is the BaryCentre -- -- -- -- -- <axe>.XDirection is the axe of upper inertia -- -- -- -- <axe>.Direction is the Normal to the average plane -- -- -- IsSingular is True if points are on line -- Tol is used to determine singular cases. . | |
static Standard_EXPORT void | Inertia (const TColgp_Array1OfPnt &Points, gp_Pnt &Bary, gp_Dir &XDir, gp_Dir &YDir, Standard_Real &Xgap, Standard_Real &YGap, Standard_Real &ZGap) |
Compute principale axes of inertia, and dispertion value of some points. . | |
static Standard_EXPORT void | RemovePointsFromArray (const Standard_Integer NumPoints, const TColStd_Array1OfReal &InParameters, Handle(TColStd_HArray1OfReal)&OutParameters) |
Warning! This assume that the InParameter is an increasing sequence of real number and it will not check for that : Unpredictable result can happen if this is not satisfied. It is the caller responsability to check for that property. . | |
static Standard_EXPORT void | DensifyArray1OfReal (const Standard_Integer MinNumPoints, const TColStd_Array1OfReal &InParameters, Handle(TColStd_HArray1OfReal)&OutParameters) |
this makes sure that there is at least MinNumPoints in OutParameters taking into account the parameters in the InParameters array provided those are in order, that is the sequence of real in the InParameter is strictly non decreasing | |
static Standard_EXPORT void | FuseIntervals (const TColStd_Array1OfReal &Interval1, const TColStd_Array1OfReal &Interval2, TColStd_SequenceOfReal &Fusion, const Standard_Real Confusion=1.0e-9) |
static Standard_EXPORT void | EvalMaxParametricDistance (const Adaptor3d_Curve &Curve, const Adaptor3d_Curve &AReferenceCurve, const Standard_Real Tolerance, const TColStd_Array1OfReal &Parameters, Standard_Real &MaxDistance) |
this will compute the maximum distance at the parameters given in the Parameters array by evaluating each parameter the two curves and taking the maximum of the evaluated distance | |
static Standard_EXPORT void | EvalMaxDistanceAlongParameter (const Adaptor3d_Curve &Curve, const Adaptor3d_Curve &AReferenceCurve, const Standard_Real Tolerance, const TColStd_Array1OfReal &Parameters, Standard_Real &MaxDistance) |
this will compute the maximum distancef at the parameters given in the Parameters array by projecting from the Curve to the reference curve and taking the minimum distance Than the maximum will be taken on those minimas. | |
static Standard_EXPORT void | CancelDenominatorDerivative (Handle(Geom_BSplineSurface)&BSurf, const Standard_Boolean UDirection, const Standard_Boolean VDirection) |
Cancel,on the boudaries,the denominator first derivative in the directions wished by the user and set its value to 1. . | |
