Standard_EXPORT | Geom2dAPI_Interpolate (const Handle(TColgp_HArray1OfPnt2d)&Points, const Standard_Boolean PeriodicFlag, const Standard_Real Tolerance) |
Tolerance is to check if the points are not too close to one an other It is also used to check if the tangent vector is not too small. There should be at least 2 points if PeriodicFlag is True then the curve will be periodic. . | |
Standard_EXPORT | Geom2dAPI_Interpolate (const Handle(TColgp_HArray1OfPnt2d)&Points, const Handle(TColStd_HArray1OfReal)&Parameters, const Standard_Boolean PeriodicFlag, const Standard_Real Tolerance) |
if PeriodicFlag is True then the curve will be periodic Warning: There should be as many parameters as there are points except if PeriodicFlag is True : then there should be one more parameter to close the curve | |
Standard_EXPORT void | Load (const gp_Vec2d &InitialTangent, const gp_Vec2d &FinalTangent) |
Assigns this constrained BSpline curve to be tangential to vectors InitialTangent and FinalTangent at its first and last points respectively (i.e. the first and last points of the table of points through which the curve passes, as defined at the time of initialization). . | |
Standard_EXPORT void | Load (const TColgp_Array1OfVec2d &Tangents, const Handle(TColStd_HArray1OfBoolean)&TangentFlags) |
Assigns this constrained BSpline curve to be tangential to vectors defined in the table Tangents, which is parallel to the table of points through which the curve passes, as defined at the time of initialization. Vectors in the table Tangents are defined only if the flag given in the parallel table TangentFlags is true: only these vectors are set as tangency constraints. . | |
Standard_EXPORT void | ClearTangents () |
Clears all tangency constraints on this constrained BSpline curve (as initialized by the function Load). . | |
Standard_EXPORT void | Perform () |
Computes the constrained BSpline curve. Use the function IsDone to verify that the computation is successful, and then the function Curve to obtain the result. . | |
Standard_EXPORT const Handle_Geom2d_BSplineCurve & | Curve () const |
Returns the computed BSpline curve. Raises StdFail_NotDone if the interpolation fails. . | |
Standard_EXPORT operator Handle( | Geom2d_BSplineCurve () const ) |
Standard_EXPORT Standard_Boolean | IsDone () const |
Returns true if the constrained BSpline curve is successfully constructed. Note: in this case, the result is given by the function Curve. . | |
