In 3D computer graphics, 3D modeling (or three-dimensional modeling) is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software. The product is called a 3D model.
3-D modeling is the use of software to create a virtual three-dimensional model of some physical object.
3-D modeling is used in many different industries, including virtual reality, video games, 3D printing, marketing, TV and motion pictures, scientific and medical imaging and computer-aided design and manufacturing CAD/CAM. 3-D modeling software generates a model through a variety of tools and approaches including:
