﻿ControlPoint Structure  # ControlPoint Structure

Represents control point geometry with three-dimensional position and weight.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll) Syntax
```[SerializableAttribute]
public struct ControlPoint : IEpsilonComparable<ControlPoint>,
IEquatable<ControlPoint>```

The ControlPoint type exposes the following members. Constructors
NameDescription ControlPoint(Point3d)
Constructs a new world 3-D, or Euclidean, control point. The 4-D representation of this is (x, y, z, 1.0). ControlPoint(Point4d)
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). ControlPoint(Point3d, Double)
Constructs a control point from a world 3-D, or Euclidean, location and a weight. The world 3-D, or Euclidean, representation is (x/w, y/w, z/w). ControlPoint(Double, Double, Double)
Constructs a new world 3-D, or Euclidean, control point. The 4-D representation is (x, y, z, 1.0). ControlPoint(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).
Top Properties
NameDescription Location
Gets or sets world 3-D, or Euclidean location of the control point.  Unset
Gets the predefined, unset control point. Weight
Gets or sets the weight of this control point. X
Gets or sets the X coordinate of the control point. Y
Gets or sets the Y coordinate of the control point. Z
Gets or sets the Z coordinate of the control point.
