There is such a project: www.ThatsMyFace.com With it, you can make a material mask (or, as they call it - sculpture) based on a 3D model of any person.
Basically, the video above explains everything. I will write just a few words about the process. ')
Upload your two photos (regular and in profile), specify the necessary parameters, create a profile with a 3D model of your head, edit it in 3D, place an order for a real mask ... and get it. For $ 2000. Or for a lower price, but smaller .
Judging by the video, from 3D you can do anything; for example, figurines or key rings with your three-dimensional image. You can also create groups of various 3D-models (friends or acquaintances).
