D3DXQuaternionRotationAxis

Rotates a quaternion about an arbitrary axis.

D3DXQuaternionRotationAxis( _ 
    QOut As D3DQUATERNION, _ 
    VAxis As D3DVECTOR, _ 
    angle As Single)

Parameters

QOut

D3DQUATERNION type that is the result of the operation, a quaternion rotated around the specified axis.

VAxis

D3DVECTOR type that identifies the axis angle.

angle

Angle of rotation, in radians. Angles are measured clockwise when looking along the rotation axis toward the origin.

Error Codes

If the function fails, an error is raised and Err.Number can be set to one of the following values.

For information on trapping errors, see the Microsoft® Visual Basic® Error Handling topic.
