For three dimensional (3-D) objects, there are three foundations which raised them into art, and upon which all 3-D art is built. These foundations are subject matter, content, and form. Digital art is a general term for a range of artistic works and practices that use digital technology as an essential part of the creative or presentation process. Since the 1970s, various names have been used to describe the process including computer art and multimedia art, and digital art is itself placed under the larger umbrella term new media art.
3 dimensional art is something like sculpture, clay art, metal works, pottery, beading or really anything that can be handled, touched or preceived to be 3 dimensional. The Mona Lisa is 2-D while the statue of David is 3-D.
