NurbsCurveFitParameters Properties

If true, the TangentMatching setting is applied at kinks. Otherwise, TangentMatching applies only to the ends of curves.

Number of control points if the NURBS curve will be clamped. Number of total control points if the NURBS curve will be periodic. This number is >= PointCount() Includes SubDFriendly constrained points and the duplicated point for a clamped closed curve.

Number of total control points if the NURBS curve will be periodic. This number is >= PointCount() and includes periodic duplicates.

If Closed() is true, the number of constrained points is (TangentMatchStart() || TangentMatchEnd() ? 1 : 0) + (TangentMatchStart()?1:0) + (TangentMatchEnd()?1:0). If Closed() is false, the number of constrained points is 2 + (SubDFriendly() ? 2 : 0) + (TangentMatchStart()?1:0) + (TangentMatchEnd()?1:0).

When CurvatureBiasIntensity == NurbsCurveFitParameters.Intensity::Custom, this value is used as the curvature bias parameter.

Curvature bias is used to make the fit curve stay close to regions of relatively high curvature. Use CurvatureBiasCoefficient() to convert this enum to the the value passed to the optimizer.

The default degree of the fit

Default number of points to sample from input curves and pass to the fitter that creates the output NURBS curve.

The degree of the resulting curve

The angle, in degrees, used to determine if when an abrupt change in tangent or curvature vector direction is a kink.

The angle, in radians, used to determine if when an abrupt change in tangent or curvature vector direction is a kink.

Gets or sets the kink splitting behavior used when fitting a NURBS curve. See also

The maximum degree of the fit

Gets the maximum number of points supported for NURBS curve fitting operations.

Maximum number of points to sample from input curves and pass to the fitter that creates the output NURBS curve.

The minimum clamped point count

The minimum closed point count

The minimum degree of the fit

Minimum number of points to sample from input curves and pass to the fitter that creates the output NURBS curve.

If OptimizeCurve = false, then all options below are ignored and the Greville interpolant is returned. Rhino 1 - Rhino 8 Rebuild command created a result similar to what's created when m_bOptimizeCurve = false.

Number of total control points if the NURBS curve will be periodic. This number is >= PointCount() and includes periodic duplicates.

Number of distinct control points in the NURBS curve fit. If a range of point counts is possible, this is the minimum number.

Gets or sets the point count range as an IndexPair.

When a range of point counts is permitted and PointCountRangeTolerance greater than 0, then searching for the NURBS curve fit terminates if the separation is less than or equal to PointCountRangeTolerance.

This is the number of points the NURBS curve is fit through. Is it common for these points to be sampled from an input curve.

When SmoothingIntensity == NurbsCurveFitParameters.Intensity::Custom, this value is used as the smoothing parameter.

Smoothing penalty used to make triples of consecutive control polygon points colinear. Use SmoothingCoefficient() to convert this enum to the the value passed to the optimizer.

Gets or sets the SubDFriendly property. When true, the resulting curve will be more likely to have good subdivision surface properties, such as fewer kinks and more even parameterization. This is accomplished by using a more aggressive kink splitting strategy and by using the SmoothingCoefficient to bias the fit towards smoother curves.

Gets ot Sets the TangentMatching value

When UniformityIntensity == NurbsCurveFitParameters.Intensity::Custom, this value is used as the uniformity parameter.

Uniformity penalty used to make the distance between control points more equal. Use UniformityCoefficient() to convert this enum to the the value passed to the optimizer.
