<P> In 3D computer graphics , 3D modeling ( or three - dimensional modeling ) is the process of developing a mathematical representation of any surface of an object ( either inanimate or living ) in three dimensions via specialized software . The product is called a 3D model . Someone who works with 3D models may be referred to as a 3D artist . It can be displayed as a two - dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena . The model can also be physically created using 3D printing devices . </P>
