class PointsToBSplineSurface from GeomAPI
|
|
|
|
---Purpose: This class is used to approximate or interpolate
|
|
-- a BSplineSurface passing through an Array2 of
|
|
-- points, with a given continuity.
|
|
-- Describes functions for building a BSpline
|
|
-- surface which approximates or interpolates a set of points.
|
|
-- A PointsToBSplineSurface object provides a framework for:
|
|
-- - defining the data of the BSpline surface to be built,
|
|
-- - implementing the approximation algorithm
|
|
-- or the interpolation algorithm, and consulting the results.
