Как правильно вращать камеру свайпами?

public class cam : MonoBehaviour,IPointerDownHandler,IDragHandler,IPointerUpHandler{ 
 
private Vector2 Origin;
private Vector2 Direction;
 
 
public GameObject camera;
public float sensX = 3f;
public float sensY = 3f;
private Quaternion OriginalRot;
 
private void Awake() 
{ 
Direction = Vector2.zero; 
OriginalRot = camera.transform.localRotation; 
}
public void OnPointerDown(PointerEventData eventdata) { 
Origin = eventdata.position; 
} 
 
public void OnPointerUp(PointerEventData eventData) 
{ 
OriginalRot = camera.transform.localRotation; 
Direction = Vector2.zero; 
 
} 
 
public void OnDrag(PointerEventData eventData) 
{ 
Vector2 currentPozition = eventData.position; 
Vector2 directionRaw = currentPozition - Origin; 
Direction = directionRaw; 
 
} 
// 
void Update() 
{ 
 
Quaternion Xqua = Quaternion.AngleAxis( Direction.x, Vector3.up); 
Quaternion Yqua = Quaternion.AngleAxis(Direction.y, Vector3.left); 
camera.transform.localRotation = OriginalRot * Xqua * Yqua; 
 
 
 
} 
}
