Detailed Description

A framework to convert a 2D curve to a BSpline.
This is done by approximation within a given tolerance.

Constructor & Destructor Documentation

Geom2dConvert_ApproxCurve::Geom2dConvert_ApproxCurve ( const Handle< Geom2d_Curve > &  Curve,
const Standard_Real  Tol2d,
const GeomAbs_Shape  Order,
const Standard_Integer  MaxSegments,
const Standard_Integer  MaxDegree 
)

Constructs an approximation framework defined by

  • the 2D conic Curve
  • the tolerance value Tol2d
  • the degree of continuity Order
  • the maximum number of segments allowed MaxSegments
  • the highest degree MaxDegree which the
    polynomial defining the BSpline is allowed to have.
