Public Member Functions | |
virtual Standard_EXPORT Standard_Boolean | D0 (const Standard_Real Param, TColgp_Array1OfPnt &Poles, TColStd_Array1OfReal &Weigths)=0 |
compute the section for v = param | |
virtual Standard_EXPORT Standard_Boolean | D1 (const Standard_Real Param, TColgp_Array1OfPnt &Poles, TColgp_Array1OfVec &DPoles, TColStd_Array1OfReal &Weigths, TColStd_Array1OfReal &DWeigths) |
compute the first derivative in v direction of the section for v = param Warning : It used only for C1 or C2 aproximation | |
virtual Standard_EXPORT Standard_Boolean | D2 (const Standard_Real Param, TColgp_Array1OfPnt &Poles, TColgp_Array1OfVec &DPoles, TColgp_Array1OfVec &D2Poles, TColStd_Array1OfReal &Weigths, TColStd_Array1OfReal &DWeigths, TColStd_Array1OfReal &D2Weigths) |
compute the second derivative in v direction of the section for v = param Warning : It used only for C2 aproximation | |
virtual Standard_EXPORT Handle_Geom_BSplineSurface | BSplineSurface () const |
give if possible an bspline Surface, like iso-v are the section. If it is not possible this methode have to get an Null Surface. It is the default implementation. | |
virtual Standard_EXPORT void | SectionShape (Standard_Integer &NbPoles, Standard_Integer &NbKnots, Standard_Integer &Degree) const =0 |
get the format of an section | |
virtual Standard_EXPORT void | Knots (TColStd_Array1OfReal &TKnots) const =0 |
get the Knots of the section | |
virtual Standard_EXPORT void | Mults (TColStd_Array1OfInteger &TMults) const =0 |
get the Multplicities of the section | |
virtual Standard_EXPORT Standard_Boolean | IsRational () const =0 |
Returns if the sections are rationnal or not . | |
virtual Standard_EXPORT Standard_Boolean | IsUPeriodic () const =0 |
Returns if the sections are periodic or not . | |
virtual Standard_EXPORT Standard_Boolean | IsVPeriodic () const =0 |
Returns if law is periodic or not . | |
virtual Standard_EXPORT Standard_Integer | NbIntervals (const GeomAbs_Shape S) const =0 |
Returns the number of intervals for continuity <s>. May be one if Continuity(me) >= <s> . | |
virtual Standard_EXPORT void | Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const =0 |
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 Standard_EXPORT void | SetInterval (const Standard_Real First, const Standard_Real Last)=0 |
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_EXPORT void | GetInterval (Standard_Real &First, Standard_Real &Last) const =0 |
Gets the bounds of the parametric interval on the function . | |
virtual Standard_EXPORT void | GetDomain (Standard_Real &First, Standard_Real &Last) const =0 |
Gets the bounds of the function parametric domain. Warning: This domain it is not modified by the SetValue method . | |
virtual Standard_EXPORT void | GetTolerance (const Standard_Real BoundTol, const Standard_Real SurfTol, const Standard_Real AngleTol, TColStd_Array1OfReal &Tol3d) const =0 |
Returns the tolerances associated at each poles to reach in approximation, to satisfy: BoundTol error at the Boundary AngleTol tangent error at the Boundary (in radian) SurfTol error inside the surface. . | |
virtual Standard_EXPORT void | SetTolerance (const Standard_Real Tol3d, const Standard_Real Tol2d) |
Is usefull, if (me) have to run numerical algorithm to perform D0, D1 or D2 The default implementation make nothing. . | |
virtual Standard_EXPORT gp_Pnt | BarycentreOfSurf () const |
Get the barycentre of Surface. An very poor estimation is sufficent. This information is usefull to perform well conditioned rational approximation. Warning: Used only if <me> IsRational . | |
virtual Standard_EXPORT Standard_Real | MaximalSection () const =0 |
Returns the length of the greater section. This information is usefull to G1's control. Warning: With an little value, approximation can be slower. . | |
virtual Standard_EXPORT void | GetMinimalWeight (TColStd_Array1OfReal &Weigths) const |
Compute the minimal value of weight for each poles in all sections. This information is usefull to control error in rational approximation. Warning: Used only if <me> IsRational . | |
virtual Standard_EXPORT Standard_Boolean | IsConstant (Standard_Real &Error) const |
Say if all sections are equals . | |
virtual Standard_EXPORT Handle_Geom_Curve | ConstantSection () const |
Return a copy of the constant Section, if me IsConstant . | |
virtual Standard_EXPORT Standard_Boolean | IsConicalLaw (Standard_Real &Error) const |
Returns True if all section are circle, with same plane,same center and linear radius evolution Return False by Default. . | |
virtual Standard_EXPORT Handle_Geom_Curve | CirclSection (const Standard_Real Param) const |
Return the circle section at parameter <param>, if <me> a IsConicalLaw . | |
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const |
