So, this is a little tool I did some time ago and was here getting dust. =)
It uses Mediapipe for face mesh capture – plus a trick of mine to convert it into textured 3D face model on-the-fly =) – and Babylon.js for 3D rendering. It can export the captured face as gltf.
Demo: face
Source-code: GitHub - imerso/facecap: Babylon.js + Mediapipe face capture
Requires a webcam!
this is INSANE! SO! COOL!
would be interesting if you published to github pages to make it more accessible!
Edit: 
click the demo link if you are as blind as me!
It is on github pages, the link is on the original post. =)
This is amazing! I believe this technique can be used for virtual space live conferencing calls by mapping webcam feeds to this and then map onto avatar meshes. Current approaches only display a square mesh of webcam feed beside the characters (could be for performance purposes).
