Technologies are moving very quickly now, and not everyone has time to follow them. So Google's algorithms are developing quite quickly and rapidly, and there is nothing to be surprised at. But somehow I don't really delve into this area, it is more interesting for me to understand 3D technologies, how they develop, the same bodyfit from Texel  https://texel.graphics/software-3d/bodyfit/ allows  you to very quickly make accurate measurements and digital models of people in less than a minute. Is not that great?
