NurbsCurvePointList.GetPoint Method (Int32, Point4d)

NurbsCurvePointListGetPoint Method (Int32, Point4d)

Gets 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)
Syntax
Copy
public bool GetPoint(
	int index,
	out Point4d point
)
Public Function GetPoint ( 
	index As Integer,
	<OutAttribute> ByRef point As Point4d
) As Boolean

Parameters

index
Type: SystemInt32
Index of control point to get.
point
Type: Rhino.GeometryPoint4d
Coordinate and 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 the override that returns world 3-D, or Euclidean, coordinates.
