23 ---Purpose: This package describes all the classes needed to approximate
24 -- points in Bezier curves. It is used in the package
26 -- The points of the same range for the approximation are
27 -- organised in MultiPointConstraints. These MultiPointConstraints
29 -- are organized in a MultiLine.
30 -- The corresponding result of a MultiLine approximation is
31 -- a MultiCurve (set of Bezier curves) which has the same
32 -- structure as a MultiLine: The MultiCurve is a set of
34 -- A point of a MultiLine can have many significations: the approximation curve
35 -- can go through this point or not, can have a given tangency, or can
36 -- have a given curvature.
37 -- Note: a CurvaturePoint is also a PassPoint and a TangencyPoint.
38 -- A TangencyPoint is also a PassPoint.
