NurbsCurvePointListSetPoint Method (Int32, Point4d) |
Sets a homogeneous control point at the given 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: 5.0
Syntax public bool SetPoint(
int index,
Point4d point
)
Public Function SetPoint (
index As Integer,
point As Point4d
) As Boolean
Parameters
- index
- Type: SystemInt32
Index of control point to set. - 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 an override that accepts world 3-D, or Euclidean, coordinates as input.
