class PointsToBSpline from Geom2dAPI
|
||||
|
||||
---Purpose: This class is used to approximate a BsplineCurve
|
||||
-- passing through an array of points, with a given
|
||||
-- Continuity.
|
||||
-- Describes functions for building a 2D BSpline
|
||||
-- curve which approximates a set of points.
|
||||
-- A PointsToBSpline object provides a framework for:
|
||||
-- - defining the data of the BSpline curve to be built,
|
||||
-- - implementing the approximation algorithm, and
|
||||
-- - consulting the results
