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

negativeInfinityShorthand for writing Vector4(float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity, float.NegativeInfinity).
oneShorthand for writing Vector4(1,1,1,1).
positiveInfinityShorthand for writing Vector4(float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity, float.PositiveInfinity).
zeroShorthand for writing Vector4(0,0,0,0).

Properties

magnitudeReturns the length of this vector (Read Only).
normalizedReturns this vector with a magnitude of 1 (Read Only).
sqrMagnitudeReturns the squared length of this vector (Read Only).
this[int]Access the x, y, z, w components using [0], [1], [2], [3] respectively.
wW component of the vector.
xX component of the vector.
yY component of the vector.
zZ component of the vector.

Constructors

Vector4Creates a new vector with given x, y, z, w components.

Public Methods

EqualsReturns true if the given vector is exactly equal to this vector.
SetSet x, y, z and w components of an existing Vector4.
ToStringReturns a nicely formatted string for this vector.

Static Methods

DistanceReturns the distance between a and b.
DotDot Product of two vectors.
LerpLinearly interpolates between two vectors.
LerpUnclampedLinearly interpolates between two vectors.
MaxReturns a vector that is made from the largest components of two vectors.
MinReturns a vector that is made from the smallest components of two vectors.
MoveTowardsMoves a point current towards target.
Normalize
ProjectProjects a vector onto another vector.
ScaleMultiplies two vectors component-wise.

Operators

operator -Subtracts one vector from another.
operator *Multiplies a vector by a number.
operator /Divides a vector by a number.
operator +Adds two vectors.
operator ==Returns true if two vectors are approximately equal.
Vector2Converts a Vector4 to a Vector2.
Vector3Converts a Vector4 to a Vector3.
Vector4Converts a Vector3 to a Vector4.
Vector4Converts a Vector2 to a Vector4.
