Hello,

I’m french so I’m not really familiar with face recognition related terms. It makes difficult to search with good terms. That’s why I ask here, showing a description of what i wanna do.

It’s based on face recognition, i found many libraries to put a rectangle on faces.

But in my case, I want get 3D face coordinates. I mean points or 3d coordinates of detection points, there is an image of my goal :

It’s 2D result but it’s the closest example. After this, i create an SVG and put circles then lines.

Anyone know if it’s possible with three.js or other library ?

Thanks

1. Three is probably not a good library to do what you are trying to do - while you can do 2D with three, [CanvasAPI](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API) is usually more readable and easier for that purpose.
2. The term you’re looking for is called `face landmarks` or `landmark detection`.
3. Maybe [face-api](https://github.com/justadudewhohacks/face-api.js/) can help you (they also share the source code, so if your aim is to learn ML - it may also be useful.)
