BSplineCreateNURBSCurve(IListPoint3D, IListDouble, Int32) Method

Returns a Point3DCollection that defines the NURBS curve (Non-uniform rational B-spline) based on the controlPoints, weights and positionsPerSegment. The curve positions are created using a fixed number of positions per segment. This is very fast to computer, but can generate too many points along nearly straight sections and too few where the curve bends sharply.

Assembly: Ab3d.PowerToys (in Ab3d.PowerToys.dll) Version: 12.0.9484.2048
Syntax
C#
public static Point3DCollection CreateNURBSCurve(
	IList<Point3D> controlPoints,
	IList<double> weights,
	int positionsPerSegment
)

Parameters

controlPoints  IListPoint3D
list of control points
weights  IListDouble
list of weights
positionsPerSegment  Int32
number of additional points to make the curve smooth - bigger value creates smoother curve

Return Value

Point3DCollection
Point3DCollection that defines the NURBS curve
