Description:
 def nlerp_quat(from_quat, to_quat, percent):
 """Return normalized linear interpolation of two quaternions. Less computationally expensive than slerp (which not implemented in this lib yet), but does not maintain a constant velocity like slerp. """


    result = lerp_quat(from_quat, to_quat, percent)
    result.normalize()
    return result
