Convert Facemesh landmarks into a UV texture and 3d Object obj file.

Please make sure that this is a feature request.

MediaPipe Solution (you are using): FaceMesh
Programming language : Python

Describe the feature and the current behavior/state: Was trying to build a solution that converts Facemesh landmarks into a Resolvable UV texture and an Object file. I've come across #1698 which I've tried to implement and was amazing, thanks to @apple2373 for their implementation, I just wanted to extend the solution a bit further.

The current implementation stretches out the UV at the very ends, where texture information isn't available, is there a way to add in an image of the same person looking a bit side-ways on the both ends to gain texture data from lower cheeks as-well and fill the UV accordingly?
The UV texture is strictly limited to the contours of the face that face-mesh provides, is there a way to extend it until the very end of the face i.e until ears, scalp-line on the top and a little bit towards the neck in the bottom?
The current implementation also doesn't generate any normalised result, it basically generates a result according to the current image size, resolution inputted, is there anyway we can normalise the result to generate same kind of obj every-single time? and possibly even an entire head.

Will this change the current api? How?

Who will benefit with this feature?

Anyone looking to generate 3d object heads from Facemesh landmark generations, 3d game developers.

Please specify the use cases for this feature:

Could directly be used to generate real word people as 3d models to be used directly in 3d spaces, such as games, or VR worlds.
