In 3D computer graphics, 3D modeling (also known as meshing) is the process of developing a mathematical representation of any three-dimensional surface of object (either inanimate or living) via specialized software. The product is called a 3D model.

In 3D computer graphics, 3D modeling (also known as meshing) is the process of developing a mathematical representation of any three-dimensional surface of object (either inanimate or living) via specialized software. The product is called a 3D model.

3D models can be displayed as a 2D image using a process called rendering. 3D models are used in Games, CAD/designing applications, game engines, and in some drawing applications. They are also used in 3d simulations and visualizations.
