LPD3DRMQUATERNION D3DRMQuaternionMultiply(LPD3DRMQUATERNION lpq,
LPD3DRMQUATERNION lpa, LPD3DRMQUATERNION lpb);
Calculates the product of two quaternion structures.
·Returns the address of the quaternion that was passed as the first parameter if successful, or zero otherwise.
lpq
Address of the D3DRMQUATERNION structure that will contain the product of the multiplication.
lpa and lpb
Addresses of the D3DRMQUATERNION structures that will be multiplied together.
