Standard_EXPORT | FairCurve_MinimalVariation (const gp_Pnt2d &P1, const gp_Pnt2d &P2, const Standard_Real Heigth, const Standard_Real Slope=0, const Standard_Real PhysicalRatio=0) |
Constructs the two contact points P1 and P2 and the geometrical characteristics of the batten (elastic beam) These include the real number values for height of deformation Height, slope value Slope, and kind of energy PhysicalRatio. The kinds of energy include: - Jerk (0) - Sagging (1). Note that the default setting for Physical Ration is in FairCurve_Batten Other parameters are initialized as follow : - FreeSliding = False - ConstraintOrder1 = 1 - ConstraintOrder2 = 1 - Angle1 = 0 - Angle2 = 0 - Curvature1 = 0 - Curvature2 = 0 - SlidingFactor = 1 Warning If PhysicalRatio equals 1, you cannot impose constraints on curvature. Exceptions NegativeValue if Height is less than or equal to 0. NullValue if the distance between P1 and P2 is less than or equal to the tolerance value for distance in Precision::Confusion: P1.IsEqual(P2, Precision::Confusion()). The function gp_Pnt2d::IsEqual tests to see if this is the case. //! Definition of the geometricals constraints . | |
void | SetCurvature1 (const Standard_Real Curvature) |
Allows you to set a new constraint on curvature at the first point. . | |
void | SetCurvature2 (const Standard_Real Curvature) |
Allows you to set a new constraint on curvature at the second point. . | |
void | SetPhysicalRatio (const Standard_Real Ratio) |
Allows you to set the physical ratio Ratio. The kinds of energy which you can specify include: 0 is only "Jerk" Energy 1 is only "Sagging" Energy like batten Warning: if Ratio is 1 it is impossible to impose curvature constraints. Raises DomainError if Ratio < 0 or Ratio > 1 . | |
virtual Standard_EXPORT Standard_Boolean | Compute (FairCurve_AnalysisCode &ACode, const Standard_Integer NbIterations=50, const Standard_Real Tolerance=1.0e-3) |
Computes the curve with respect to the constraints, NbIterations and Tolerance. The tolerance setting allows you to control the precision of computation, and the maximum number of iterations allows you to set a limit on computation time. . | |
Standard_Real | GetCurvature1 () const |
Returns the first established curvature. . | |
Standard_Real | GetCurvature2 () const |
Returns the second established curvature. . | |
Standard_Real | GetPhysicalRatio () const |
Returns the physical ratio, or kind of energy. . | |
virtual Standard_EXPORT void | Dump (Standard_OStream &o) const |
Prints on the stream o information on the current state of the object. Is used to redefine the operator <<. . | |
