The D3DXQuaternionConjugate function returns the conjugate of the given quaternion.
D3DXQUATERNION* D3DXQuaternionConjugate( D3DXQUATERNION* pOut, const D3DXQUATERNION* pQ );
A pointer to a D3DXQUATERNION structure that is the conjugate of the given quaternion.
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.
