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.

Member Function Documentation

◆ Curve()

Handle< Geom2d_BSplineCurve > Geom2dConvert_ApproxCurve::Curve ( ) const

Returns the 2D BSpline curve resulting from the approximation algorithm.

◆ Dump()

void Geom2dConvert_ApproxCurve::Dump ( Standard_OStream o) const

Print on the stream o information about the object.

◆ HasResult()

Standard_Boolean Geom2dConvert_ApproxCurve::HasResult ( ) const

returns Standard_True if the approximation did come out with a result that is not NECESSARELY within the required tolerance

◆ IsDone()

Standard_Boolean Geom2dConvert_ApproxCurve::IsDone ( ) const

returns Standard_True if the approximation has been done with within requiered tolerance

◆ MaxError()

Standard_Real Geom2dConvert_ApproxCurve::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)
