Can i get info on Digitizing solid objects plz?

Hey I’m a student/Tech atm and I want to do some research on digitizing: plants, animals, people, ect., and what you can do with it. Is there anyone out there that can point me to some info on the subject or maybe even give me some? My email adress is my name xD. Plz feel free to email me any time. I’m realy very interested especaily in what they are doing now. I’ve seena company that digitizes objects(people, designs, blah blah) and then makes them larger out of polyurithane using computers entirely.. So I’m thinking there might be a way to use it other ways :/.. Well anyway any info i can get will be helpfull
