I am using [MediaPipe Face Mesh](https://google.github.io/mediapipe/solutions/face_mesh.html) to extract face landmarks using webcam input. Then I load a 3D sunglass model and display it on top of the webcam input. Assuming I have 3 key landmarks points of the face (one above the nose, and two above the ears) I want to position and rotate the sunglass model based on these three points.
