NurbsCurvePointList.SetPoint (Int32, Double, Double, Double, Double)

Public Class

Sets a homogeneous control point at the given index, where the 4-D representation is (x, y, z, w). The world 3-D, or Euclidean, representation is (x/w, y/w, z/w).

Namespace: Rhino.Geometry.Collections

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**5.0

Syntax

public bool SetPoint(
  int index,
  double x,
  double y,
  double z,
  double weight
)

Parameters

index

Type:System.Int32
Index of control point to set.

x

Type:System.Double
X coordinate of control point.

y

Type:System.Double
Y coordinate of control point.

z

Type:System.Double
Z coordinate of control point.

weight

Type:System.Double
Weight of control point.

Return Value

Type:Boolean
true on success, false on failure.

Remarks

For expert use only. If you do not understand homogeneous coordinates, then use an override that accepts world 3-D, or Euclidean, coordinates as input.
