GeomConvert_ApproxCurve Class Reference

A framework to convert a 3D curve to a 3D BSpline.
This is done by approximation to a BSpline curve within a given tolerance.

#include <GeomConvert_ApproxCurve.hxx>

 GeomConvert_ApproxCurve (const Handle< Geom_Curve > &Curve, const Standard_Real Tol3d, const GeomAbs_Shape Order, const Standard_Integer MaxSegments, const Standard_Integer MaxDegree)
 Constructs a curve approximation framework defined by -

Handle_Geom_BSplineCurve Curve () const
 Returns the BSpline curve resulting from the approximation algorithm.

Standard_Boolean IsDone () const
 returns Standard_True if the approximation has
been done 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

GeomConvert_ApproxCurve::GeomConvert_ApproxCurve ( const Handle< Geom_Curve > &  Curve,
const Standard_Real  Tol3d,
const GeomAbs_Shape  Order,
const Standard_Integer  MaxSegments,
const Standard_Integer  MaxDegree 
)
  • the conic Curve,
  • the tolerance value Tol3d,
  • the degree of continuity Order,
  • the maximum number of segments
    MaxSegments allowed in the resulting BSpline curve, and
  • the highest degree MaxDeg which the
    polynomial defining the BSpline curve may have.
