Rol of UV468 array in facemeshcoords.ts

[saeidn95]

I would appreciate an explanation to on the role of UV468 in (https://github.com/vladmandic/human/blob/62396317f5c31b2ec5bc7de2e9eb53b8978b9f28/src/face/facemeshcoords.ts#L81C14-L81C20). The best that I have been able to trace it is to this line code (

human/src/human.ts

Line 167 in 6239631

this.faceUVMap = facemesh.uvmap;

). But I cannot figure out where and how it is being used.

that's a precalculated standardized uvmap for ease-of-use with 3d libraries such as three.js or babylonjs.
