NurbsSurfacePointListSetPoint Method (Int32, Int32, Point4d)

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
public bool SetPoint(
	int u,
	int v,
	Point4d point
)

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.
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 an override that accepts world 3-D, or Euclidean, coordinates as input.
