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>

<SerializableAttribute>
Public Structure ControlPoint
	Implements IEpsilonComparable(Of ControlPoint), IEquatable(Of ControlPoint)

The ControlPoint type exposes the following members.

Constructors

	Name	Description
	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).

Properties

	Name	Description
	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.

Methods

	Name	Description
	EpsilonEquals	Check that all values in other are within epsilon of the values in this
	Equals(ControlPoint)	Determines if two points exactly match.
	Equals(Object)	Indicates whether this instance and a specified object are equal. (Inherited from ValueType.)
	GetHashCode	Returns the hash code for this instance. (Inherited from ValueType.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType.)
