Language:

Conjugates and re-normalizes a quaternion.

Definition

Visual Basic Public Shared Function Invert( _
    ByVal q As Quaternion _
) As Quaternion

C# public static Quaternion Invert(
    Quaternion q
);

C++ public:
static Quaternion Invert(
    Quaternion q
);

JScript public static function Invert(
    q : Quaternion
) : Quaternion;

Visual Basic	Public Shared Function Invert( _ ByVal q As Quaternion _ ) As Quaternion
C#	public static Quaternion Invert( Quaternion q );
C++	public: static Quaternion Invert( Quaternion q );
JScript	public static function Invert( q : Quaternion ) : Quaternion;

Parameters

q Microsoft.DirectX.Quaternion
Source Quaternion structure.

Return Value

Microsoft.DirectX.Quaternion
A Quaternion structure that is the inverse of the quaternion passed into the q parameter.

Remarks

A unit quaternion is defined by the following equation.
q == (cos(theta), sin(theta) * v) where |v| = 1
The natural logarithm of q is ln(q) = (0, theta * v)
