Namespace: Microsoft.WindowsMobile.DirectX
Assembly: Microsoft.WindowsMobile.DirectX (in Microsoft.WindowsMobile.DirectX.dll)

Syntax

'Declaration
Public Shared Sub ToAxisAngle ( _
    q As Quaternion, _
    ByRef axis As Vector3, _
    ByRef angle As Single _
)
'Usage
Dim q As Quaternion
Dim axis As Vector3
Dim angle As Single

Quaternion.ToAxisAngle(q, axis, angle)

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

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

static member ToAxisAngle : 
        q:Quaternion * 
        axis:Vector3 byref * 
        angle:float32 byref -> unit

Parameters

q
Type: Microsoft.WindowsMobile.DirectX.Quaternion
Source Quaternion structure.

axis
Type: Microsoft.WindowsMobile.DirectX.Vector3%
A Vector3 structure passed by reference, that identifies axis of rotation of the quaternion.

angle
Type: System.Single%
A number, passed by reference, that identifies the angle of rotation, in radians, of the quaternion.

Remarks

This method requires unit quaternions.
