How are Realistic Virtual Humans made?

The "metaverse" will be built based on realistic virtual persons, and this foundation will facilitate distant presence, cooperation, education, and entertainment. To make this possible, new 3D virtual human creation tools must be developed that are easy to use and can be easily animated. Traditionally, this has required a lot of time and money spent by the AI artist. Because of this, these methods are not scalable. Allowing people to build their own avatars from one or more photographs is a more realistic solution.
