3D 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 termed a 3D model. Someone who works with 3D models could also be referred to as a 3D artist. The model also can be physically created using 3D printing devices.
Models can be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts like sculpting.
