NurbsSurfacePointListGetPoint Method (Int32, Int32, Point4d) |
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
)
Public Function GetPoint (
u As Integer,
v As Integer,
<OutAttribute> ByRef point As Point4d
) 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. - point
- Type: Rhino.GeometryPoint4d
Coordinate and weight of control point.
Return Value
Type:
Booleantrue 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.
