D3DXQuaternionConjugate function
Note
The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Returns the conjugate of a quaternion.
Syntax
D3DXQUATERNION* D3DXQuaternionConjugate(
_Inout_ D3DXQUATERNION *pOut,
_In_ const D3DXQUATERNION *pQ
);
Parameters
-
pOut [in, out]
-
Type: D3DXQUATERNION*
Pointer to the D3DXQUATERNION structure that is the result of the operation.
-
pQ [in]
-
Type: const D3DXQUATERNION*
Pointer to the source D3DXQUATERNION structure.
Return value
Type: D3DXQUATERNION*
Pointer to a D3DXQUATERNION structure that is the conjugate of the quaternion.
Remarks
Given a quaternion (x, y, z, w), the D3DXQuaternionConjugate function will return the quaternion (-x, -y, -z, w).
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXQuaternionConjugate function can be used as a parameter for another function.
Use D3DXQuaternionNormalize for any quaternion input that is not already normalized.
