Rotates a quaternion about an arbitrary axis.
Syntax
D3DXQUATERNION *D3DXQuaternionRotationAxis(
D3DXQUATERNION *pOut, CONST D3DXVECTOR3 *pV, FLOAT Angle );
Parameters
- pOut
- [in, out] Pointer to the D3DXQUATERNION structure that is the result of the operation.
- pV
- [in] Pointer to the D3DXVECTOR3 structure that identifies the axis angle.
- Angle
- [in] Angle of rotation, in radians. Angles are measured clockwise when looking along the rotation axis toward the origin.
Return Value
Pointer to a D3DXQUATERNION structure rotated around the specified axis.
Remarks
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXQuaternionRotationAxis function can be used as a parameter for another function.
