Defination of 3D (computer graphics)
3D (on G4D) is referred as computer graphics or graphics that used a three-dimensional representation of geometric data for the purpose of creating a rendering of a 2D image.A 3D model allows items that appeared flat to the human eye to be display in a way that allows various dimensions to be represented. These dimensions include width, depth, and height.
A 3D model is therefore a mathematical representation of any three-dimensional object. A model is not technically a graphic until it is displayed or rendered. A model can be displayed visually as a two-dimensional (2D) image through a process called 3D rendering.
