BezierSurface.GetControlVertex4d Method

RhinoCommon API

BezierSurfaceGetControlVertex4d Method

Get location of a control vertex.

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

Syntax

public Point4d GetControlVertex4d(
	int i,
	int j
)

Public Function GetControlVertex4d ( 
	i As Integer,
	j As Integer
) As Point4d

Parameters

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

Return Value

Type: Point4d
Homogeneous value of control vertex. If the bezier is not rational, the weight is 1.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	when index is out of range
