Is there a way to digitalize objects from real life and put them in a game?

I want to make my characters out of clay, then, I don’t know, take a bunch of pictures of them and then put them in some kind of 3D software as 3D models and use them in a game later. Can I do that? That’d make things so much easier.

there are quite a few ways to do that, but to be very honest most solutions that i know of will never produce a game ready mesh, at most they create a high res mesh to which you need to create a low poly version.
there are a few low cost solutions like David Scanner or photosculpt/ and reconstructme

see-ing as i have a beamer David will be an option for me as i’ve tested the demo, the others not sure about
