class Interpolate from GeomLib
---Purpose: this class is used to construct a BSpline curve by
-- interpolation of points at given parameters The
-- continuity of the curve is degree - 1 and the
-- method used when boundary condition are not given
-- is to use odd degrees and null the derivatives on
-- both sides from degree -1 down to (degree+1) / 2
-- When even degree is given the returned curve is of
-- degree - 1 so that the degree of the curve is odd
uses
Array1OfPnt from TColgp,
Array1OfReal from TColStd,
InterpolationErrors from GeomLib,
BSplineCurve from Geom
raises
NotDone from StdFail,
OutOfRange from Standard
is
Create( Degree : Integer from Standard ;
NumPoints : Integer from Standard ;
Points : Array1OfPnt from TColgp ;
Parameters : Array1OfReal from TColStd)
returns Interpolate from GeomLib ;
IsDone(me) returns Boolean from Standard
---Purpose:
-- returns if everything went OK
---C++: inline
is static;
Error(me) returns InterpolationErrors from GeomLib
---Purpose: returns the error type if any
---C++: inline
--
is static ;
Curve(me)
---Purpose: returns the interpolated curve of the requested degree
returns BSplineCurve from Geom
raises
