facetracking - faceMask vs transformmatrix

[yrostudio]

Hi, in you're example i'm trying to match the white faceMask to the canonical_face_model connected to the transformmatrix you put on your example. rotation, ... seems to be ok. But the Z (zoom in / out with head distance from camera. When i'm closed to the camera the canonical_face_model is smaller and bigger when i'm far for the camera.

Any idea ?

My idea is to make a "kind of snapchat filter" with a 3D head oculter that follow the head size.

Thanks
