Geom2dConvert_ApproxCurve Class Reference

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

#include <Geom2dConvert_ApproxCurve.hxx>

DEFINE_STANDARD_ALLOC 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

Handle_Geom2d_BSplineCurve Curve () const
 Returns the 2D BSpline curve resulting from the
approximation algorithm.

Standard_Boolean IsDone () const
 returns Standard_True if the approximation has
been done with within requiered tolerance

Standard_Boolean HasResult () const
 returns Standard_True if the approximation did come out
with a result that is not NECESSARELY within the required tolerance

Standard_Real MaxError () const
 Returns the greatest distance between a point on the
source conic and the BSpline curve resulting from the
approximation. (>0 when an approximation
has been done, 0 if no approximation)

void Dump (Standard_OStream &o) const
 Print on the stream o information about the object


Constructor & Destructor Documentation

  • 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.
