Find a 3D piece of art in your home. It can be something as simple as a bowl with a design on it if you don’t have many statues lying around. Take a picture of the object. How does the 2D image (picture) compare with the actual 3D object? When would the 2D image be more useful than the 3D? What gets lost or altered when a 3D object is represented in 2D?

Do you own any bowls with a design? Take a picture...

How a 2D image would compare to a 3D object would be drastic. The 3D object is something you can see all around, it's more complex. While a 2D image is something that would have to be carefully looked at, and thought about. (For example: If you were to see a 2D image of a bowl, you'd have to guess the design would be the same all around.) A 2D image could be more useful in a lot of ways, such as sending it to someone, or planning out something using multiple images, and identifying what you would make, while a 3D object would have to be shown to someone by hand, made by hand, or with an expensive website that can create 3D models.  Sometimes, a 3D object is changed when altered into a 2D image, like being unable to see the back, or laying it out in a 2D way, by spreading it out like a cardboard box, or, laying it out flat. (For example, a bowl could become something with corners if placed out in such a way.)
