ControlPoint (Double, Double, Double, Double)

Public Constructor

Constructs a new homogeneous control point, 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

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**5.0

Syntax

public ControlPoint(
  double x,
  double y,
  double z,
  double weight
)

Parameters

x

Type:System.Double
X coordinate of the control point.

y

Type:System.Double
Y coordinate of the control point.

z

Type:System.Double
Z coordinate of the control point.

weight

Type:System.Double
Weight factor of the control point. You should not use weights less than or equal to zero.

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.
