NurbsSurfacePointList.SetPoint Method (Int32, Int32, Double, Double, Double, Double)

NurbsSurfacePointListSetPoint Method (Int32, Int32, Double, Double, Double, Double)

Sets a homogeneous control point at the given (u, v) 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 SetPoint(
	int u,
	int v,
	double x,
	double y,
	double z,
	double weight
)
Public Function SetPoint ( 
	u As Integer,
	v As Integer,
	x As Double,
	y As Double,
	z As Double,
	weight As Double
) As Boolean

Parameters

u
Type: SystemInt32
Index of control point in the surface U direction.
v
Type: SystemInt32
Index of control point in the surface V direction.
x
Type: SystemDouble
X coordinate of control point.
y
Type: SystemDouble
Y coordinate of control point.
z
Type: SystemDouble
Z coordinate of control point.
weight
Type: SystemDouble
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.
