Description

Representation of four-dimensional vectors.

This structure is used in some places to represent four component vectors (e.g. mesh tangents, parameters for shaders). In the majority of other cases a Vector3 is used.

Static Properties

Property	Description
negativeInfinity	Shorthand for writing Vector4(float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity).
one	Shorthand for writing Vector4(1,1,1,1).
positiveInfinity	Shorthand for writing Vector4(float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity).
zero	Shorthand for writing Vector4(0,0,0,0).

Properties

Property	Description
magnitude	Returns the length of this vector (Read Only).
normalized	Creates a normalized copy of a vector based on the current vector.
sqrMagnitude	Returns the squared length of this vector (Read Only).
this[int]	Access the x, y, z, w components using [0], [1], [2], [3] respectively.
w	W component of the vector.
x	X component of the vector.
y	Y component of the vector.
z	Z component of the vector.

Constructors

Constructor	Description
Vector4	Creates a new vector with given x, y, z, w components.

Public Methods

Method	Description
