UnsafeNativeMethods.Quaternion.ToAxisAngle Method

Language:

Computes a quaternion's axis and angle of rotation.

Note: For programming in Microsoft Visual Basic .NET or Microsoft JScript .NET, use the equivalent method in the Microsoft.DirectX structures.

Definition

Visual Basic Public Shared Sub ToAxisAngle( _
    ByVal pQuat As Quaternion, _
    ByVal pAxis As Vector3, _
    ByVal pAngle As Single _
)

C# public static void ToAxisAngle(
    Quaternion pQuat,
    Vector3 pAxis,
    float pAngle
);

C++ public:
static void ToAxisAngle(
    Quaternion pQuat,
    Vector3 pAxis,
    float pAngle
);

JScript public static function ToAxisAngle(
    pQuat : Quaternion,
    pAxis : Vector3,
    pAngle : float
);

Visual Basic	Public Shared Sub ToAxisAngle( _ ByVal pQuat As Quaternion, _ ByVal pAxis As Vector3, _ ByVal pAngle As Single _ )
C#	public static void ToAxisAngle( Quaternion pQuat, Vector3 pAxis, float pAngle );
C++	public: static void ToAxisAngle( Quaternion pQuat, Vector3 pAxis, float pAngle );
JScript	public static function ToAxisAngle( pQuat : Quaternion, pAxis : Vector3, pAngle : float );

Parameters

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

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

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

Remarks

This method requires unit quaternions.

pQuat	Microsoft.DirectX.Quaternion Source Quaternion structure. See Remarks.
pAxis	Microsoft.DirectX.Vector3 A Vector3 structure that identifies the quaternion's axis of rotation.
pAngle	System.Single A Single value that identifies the quaternion's angle of rotation, in radians.
