Vector2 Structure (Microsoft.DirectX)

Describes and manipulates a vector in two-dimensional (2-D) space.

Definition

Visual Basic	Public Structure Vector2
C#	public struct Vector2
C++	public value class Vector2 sealed
JScript	In JScript, you can use structures, but you cannot define your own.

Members Table

The following table lists the members exposed by the object.

Fields

Field	Description
X	Retrieves or sets the x component of a 2-D vector.
Y	Retrieves or sets the y component of a 2-D vector.

Methods

Method	Description
Add	Adds two 2-D vectors.
BaryCentric	Returns a point in barycentric coordinates, using specified 2-D vectors.
CatmullRom	Performs a Catmull-Rom interpolation using specified 2-D vectors.
Ccw	Returns the z component by calculating the cross product of two 2-D vectors.
Dot	Determines the dot product of two 2-D vectors.
Equals	Returns a value that indicates whether the current instance is equal to a specified object.
