Syntax

[SerializableAttribute]
public struct Point2d : ISerializable, IEquatable<Point2d>, 
	IComparable<Point2d>, IComparable, IEpsilonComparable<Point2d>,

The Point2d type exposes the following members.

Constructors

	Name	Description
	Point2d(Point2d)	Initializes a new instance of Point2d by copying another Point2d.
	Point2d(Point3d)	Initializes a new instance of Point3d by copying the first two coordinates of a Point3d.
	Point2d(Vector2d)	Initializes a new instance of Point2d by converting a vector.
	Point2d(Double, Double)	Initializes a new instance of Point2d from coordinates.

Properties

	Name	Description
	IsValid	If any coordinate of a point is UnsetValue, then the point is not valid.
	Item	Accesses the coordinates of this point.
	MaximumCoordinate	Gets the largest valid coordinate, or RhinoMath.UnsetValue if no coordinate is valid.
	MinimumCoordinate	Gets the smallest (both positive and negative) valid coordinate, or RhinoMath.UnsetValue if no coordinate is valid.
	Origin	Gets a point at 0,0.
	Unset	Gets a point at RhinoMath.UnsetValue,RhinoMath.UnsetValue.
	X	Gets or sets the X (first) coordinate of the point.
	Y	Gets or sets the Y (second) coordinate of the point.

Methods

	Name	Description
	Add(Point2d, Point2d)	Adds a point with a point. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	Add(Point2d, Vector2d)	Adds a point with a vector. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	Add(Vector2d, Point2d)	Adds a vector with a point. (Provided for languages that do not support operator overloading. You can use the + operator otherwise)
	CompareTo	Compares this Point2d with another Point2d. Coordinates evaluation priority is first X, then Y.
	DistanceTo	Computes the distance between two points.
	DistanceToSquared	Computes the square of the distance between two 2d points. This method is usually largely faster than DistanceTo().
	Divide	Divides a Point2d by a number. (Provided for languages that do not support operator overloading. You can use the / operator otherwise)
	EpsilonEquals	Check that all values in other are within epsilon of the values in this
	Equals(Object)	Determines whether the specified System.Object is a Point2d and has the same values as the present point. (Overrides ValueTypeEquals(Object).)
	Equals(Point2d)	Determines whether the specified Point2d has the same values as the present point.
	GetHashCode	Computes a hash number that represents the current point. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Multiply(Double, Point2d)	Multiplies a Point2d by a number. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Multiply(Point2d, Double)	Multiplies a Point2d by a number. (Provided for languages that do not support operator overloading. You can use the * operator otherwise)
	Subtract(Point2d, Point2d)	Subtracts the second point from the first point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	Subtract(Point2d, Vector2d)	Subtracts a vector from a point. (Provided for languages that do not support operator overloading. You can use the - operator otherwise)
	ToString	Constructs the string representation for the current point. (Overrides ValueTypeToString.)
	ToString(String, IFormatProvider)	Formats the value of the current instance using the specified format.
	Transform	Transforms the present point in place. The transformation matrix acts on the left of the point. i.e., result = transformation*point

Operators

	Name	Description
	Addition(Point2d, Point2d)	Adds a point with a point.
	Addition(Point2d, Vector2d)	Adds a point with a vector.
	Addition(Vector2d, Point2d)	Adds a vector with a point.
	Division	Divides a Point2d by a number.
	Equality	Determines whether two Point2d have equal values.
	GreaterThan	Determines whether the first specified Point2d comes after (has superior sorting value than) the second point. Coordinates evaluation priority is first X, then Y.
	GreaterThanOrEqual	Determines whether the first specified Point2d comes after (has superior sorting value than) the second point, or it is equal to it. Coordinates evaluation priority is first X, then Y.
	Inequality	Determines whether two Point2d have different values.
	LessThan	Determines whether the first specified point comes before (has inferior sorting value than) the second point. Coordinates evaluation priority is first X, then Y.
	LessThanOrEqual	Determines whether the first specified point comes before (has inferior sorting value than) the second point, or it is equal to it. Coordinates evaluation priority is first X, then Y.
	Multiply(Double, Point2d)	Multiplies a Point2d by a number.
	Multiply(Point2d, Double)	Multiplies a Point2d by a number.
	Subtraction(Point2d, Point2d)	Subtracts point2 from point1.
	Subtraction(Point2d, Vector2d)	Subtracts a vector from a point.
