NurbsSurfacePointList.GetPoint (Int32, Int32, Point4d.)

Public Class

Gets 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)

**Since:**6.0

Syntax

public bool GetPoint(
  int u,
  int v,
  out Point4d point
)

Parameters

u

Type:System.Int32
Index of control point in the surface U direction.

v

Type:System.Int32
Index of control point in the surface V direction.

point

Type: Rhino.Geometry.Point4d.
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.
