Quaternion.ToAxisAngle Method

Language:

Computes a quaternion's axis and angle of rotation.

Definition

Visual Basic Public Shared Sub ToAxisAngle( _
    ByVal q As Quaternion, _
    ByRef axis As Vector3, _
    ByRef angle As Single _
)

C# public static void ToAxisAngle(
    Quaternion q,
    ref Vector3 axis,
    ref float angle
);

C++ public:
static void ToAxisAngle(
    Quaternion q,
    Vector3% axis,
    float% angle
);

JScript public static function ToAxisAngle(
    q : Quaternion,
    axis : Vector3,
    angle : float
);

Visual Basic	Public Shared Sub ToAxisAngle( _ ByVal q As Quaternion, _ ByRef axis As Vector3, _ ByRef angle As Single _ )
C#	public static void ToAxisAngle( Quaternion q, ref Vector3 axis, ref float angle );
C++	public: static void ToAxisAngle( Quaternion q, Vector3% axis, float% angle );
JScript	public static function ToAxisAngle( q : Quaternion, axis : Vector3, angle : float );

Parameters

q Microsoft.DirectX.Quaternion
Source Quaternion structure. See Remarks.

axis Microsoft.DirectX.Vector3
A Vector3 structure that identifies the quaternion's axis of rotation.

angle System.Single
A Single value that identifies the quaternion's angle of rotation, in radians.

Remarks

This method requires unit quaternions.
