ControlPoint Constructor (Double, Double, Double, Double)

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

Parameters

x
Type: SystemDouble
X coordinate of the control point.
y
Type: SystemDouble
Y coordinate of the control point.
z
Type: SystemDouble
Z coordinate of the control point.
weight
Type: SystemDouble
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.
