Describes a four-dimensional vector (x, y, z, w).

The Quaternion type exposes the following members.

Constructors

	Name	Description
	Quaternion	Initializes a new instance of the Quaternion class.

Methods

	Name	Description
	Add	Adds two quaternions.
	Conjugate	Returns the conjugate of a quaternion.
	Dot	Returns the dot product of two quaternions.
	Equals	Returns a value that indicates whether the current instance is equal to a specified object. (Overrides ValueType.Equals(Object).)
	Exp	Overloaded. Calculates the exponential of a quaternion.
	Finalize	Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for the current instance. (Overrides ValueType.GetHashCode().)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Invert	Overloaded. Conjugates and renormalizes a quaternion.
	Length	Overloaded. Returns the length of a quaternion.
	LengthSq	Overloaded. Returns the square of the length of a quaternion.
	Ln	Overloaded. Calculates the natural logarithm of a quaternion.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Multiply	Overloaded. Determines the product of two quaternions.
	Normalize	Overloaded. Creates the norm of a quaternion.
	RotationAxis	Builds a quaternion that is rotated around an arbitrary axis.
	RotationMatrix	Builds a quaternion from a rotation matrix.
	RotationYawPitchRoll	Builds a quaternion with the given yaw, pitch, and roll.
	Slerp	Interpolates between two quaternions, using spherical linear interpolation.
	Squad	Interpolates between quaternions, using spherical quadrangle interpolation.
	SquadSetup	Sets up control points for spherical quadrangle interpolation.
	Subtract	Subtracts two quaternion instances.
	ToAxisAngle	Computes the axis and angle of rotation for a quaternion.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Operators

	Name	Description
	Addition	Adds two instances of the Quaternion structure.
	Equality	Compares the specified quaternions to determine whether they are the same.
	Inequality	Compares the current specified quaternions to determine whether they are different.
	Multiply	Overloaded. Determines the product of two quaternions.
	Subtraction	Subtracts two quaternions.
	UnaryNegation	Returns the negation of the specified quaternion.

Fields

	Name	Description
	W	Represents the w component of the quaternion.
	X	Represents the x component of the quaternion.
	Y	Represents the y component of the quaternion.
	Z	Represents the z component of the quaternion.
