Gets the homogeneous (4D) value of a control vertex at the specified index.

Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll)

Since: 5.0

Syntax

public Point4d GetControlVertex4d(
	int index
)

Public Function GetControlVertex4d ( 
	index As Integer
) As Point4d

Parameters

index: Type: SystemInt32
Control vertex index (0 <= index < ControlVertexCount).

Return Value

Type: Point4d
The homogeneous value of the control vertex. If the Bezier is not rational, the weight is 1. Returns Unset if the index is out of range or the control vertex cannot be retrieved.

Exceptions

Exception	Condition
