“…The camera motion graph data creation section collects the rotation value of motion frame referring to the relative value of camera X, Y, and Z so as to edit the rotation value for the axis of camera X, Y, and Z while playing. In this process, the way to collect the relative rotation value of camera is to subtract the original angle from the current angle and it becomes the data for camera motion graph just like "Vector3 angle = Vector3 (CurmainCamera-OriginMainCamera);" [10].…”
