Parameters: nurbs_curve - [out] NURBS representation returned here tolerance - [in] tolerance to use when creating NURBS representation. subdomain - [in] if not nullptr, then the NURBS representation for this portion of the curve is returned. Returns: 0 unable to create NURBS representation with desired accuracy. 1 success - returned NURBS parameterization matches the curve's to wthe desired accuracy 2 success - returned NURBS point locus matches the curve's to the desired accuracy and the domain of the NURBS curve is correct. On However, This curve's parameterization and the NURBS curve parameterization may not match to the desired accuracy. This situation happens when getting NURBS representations of curves that have a transendental parameterization like circles Remarks: This is a low-level virtual function. If you do not need the parameterization information provided by the return code, then ON_Curve::NurbsCurve may be easier to use. See Also: ON_Curve::NurbsCurve
