Syntax

public struct Vector4

The Vector4 type exposes the following members.

Constructors

	Name	Description
	Vector4(Double)	Creates a vector from an array. Sets w=1 if the array has less than four elements.
	Vector4(Vector3, Double)	Creates a vector from a 3-vector and a scalar.
	Vector4(Double, Double, Double)	Creates a vector from three doubles and sets w=1.
	Vector4(Double, Double, Double, Double)	Creates a vector from four doubles.

Properties

	Name	Description
	IsNaN	Returns a value indicating whether any elements evaluates to a value that is not a number (NaN).
	Item	Array access.

Methods

	Name	Description
	Add	Element-wise addition.
	AlmostEquals(Vector4)	Comparison method for vectors with default tolerance
	AlmostEquals(Vector4, Double)	Comparison method for vectors with tolerance
	Divide	Vector-scalar division method.
	Dot	Dot product.
	Equals	(Overrides ValueTypeEquals(Object).)
	GetHashCode	(Overrides ValueTypeGetHashCode.)
	GetType	(Inherited from Object.)
	Length	Returns the magnitude of this.
	Multiply	Vector-scalar multiplication.
	Normalize	Ensures that the magnitude of this is 1.
	Subtract	Element-wise subtraction.
	ToArray	Returns the elements (x,y,z,w) as an array
	ToString	Returns a string in the format [x y z w] (Overrides ValueTypeToString.)

Operators

	Name	Description
	Addition	Element-wise addition operator.
	Division	Vector-scalar division operator.
	Equality	Equality operator
	(Double to Vector4)	Array to vector conversion.
	Inequality	Inequality operator
	Multiply(Double, Vector4)	Scalar-Vector multiplication operator.
	Multiply(Vector4, Double)	Vector-scalar multiplication operator.
	Subtraction	Element-wise subtraction operator.
	UnaryNegation	Unary negation operator.
