Constructs a 3D NURBS curve from a list of control points.
Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0
C#
public static NurbsCurve Create(
bool periodic,
int degree,
IEnumerable<Point3d> points
)VB
Public Shared Function Create (
periodic As Boolean,
degree As Integer,
points As IEnumerable(Of Point3d)
) As NurbsCurve
- periodic
- Type: System.Boolean
If true, create a periodic uniform curve. If false, create a clamped uniform curve. - degree
- Type: System.Int32
(>=1) degree=order-1. - points
- Type: System.Collections.Generic.IEnumerable(Point3d)
control vertex locations.
Type: NurbsCurve
new NURBS curve on success null on error.
