Bounding box array of points

Good night,

I am looking for a way with the face points array, get its bounding box and face rotation (tilt, yaw, roll).

`mat = np.array(face_landmarks.landmark)`

It returns the array of face points if I can't find out how it's rotated, at least through the boundigbox knowing its size

Can you help me

CODE

```

camera = cv2.VideoCapture("F:/C0010.MP4")

mp_face_mesh = mp.solutions.face_mesh
mp_drawing = mp.solutions.drawing_utils

with mp_face_mesh.FaceMesh(
static_image_mode = False,
max_num_faces = 1,
min_detection_confidence=0.5) as face_mesh:

while True:
ret, frame = camera.read()
if (ret == 0):
break

frame_rgb = cv2.cvtColor(frame,cv2.COLOR_BGR2RGB)
results = face_mesh.process(frame_rgb)

if results.multi_face_landmarks is not None:
for face_landmarks in results.multi_face_landmarks:
mp_drawing.draw_landmarks(frame,face_landmarks)

ys, zs, xs = getaxis(face_landmarks.landmark)
mat = np.array(face_landmarks.landmark)
print (rotation_angles(mat, "XYZ"))

cv2.imshow("FRAME",frame)
k = cv2.waitKey(1) & 0xFF

if (k == 27):
break

camera.release()

```

The issue mentions FaceMesh's face_landmarks.landmark and the np.array(mat) conversion, but no repository file, test, or pyntcloud entry point. First determine whether bounding-box and face-rotation support is in scope, then define the expected inputs and outputs before locating the relevant tests or adding one.
