Available algorithms for creating UV margin/padding?

Question

3D

An example of what I'm talking about.

I can’t dig something on this topic in Google, it seems I can’t formulate the question correctly.

Any information is welcome, from code to all sorts of theories and descriptions of algorithms.
I need to implement something similar for myself, I don't need ready-made programs like blender, substances painter, 3d max, etc. need an algorithm.

Thanks to.

Answer 1

I found this and it seems to work as it should.
