The D3DXQuaternionSquad function interpolates between quaternions, using spherical quadrangle interpolation.
D3DXQUATERNION* D3DXQuaternionSquad( D3DXQUATERNION* pOut, const D3DXQUATERNION* pQ1, const D3DXQUATERNION* pQ2, const D3DXQUATERNION* pQ3, const D3DXQUATERNION* pQ4, float t );
A pointer to a D3DXQUATERNION structure that is the result of the spherical quadrangle interpolation.
The function uses the following sequence of spherical linear interpolation operations: Slerp(Slerp(Q1, Q4, t), Slerp(Q2, Q3, t), 2t(1-t))
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXQuaternionSquad function can be used as a parameter for another function.
