In 3D computer graphics, 3D modelling (or three-dimensional modelling) is the process of developing a mathematical representation of any surface of an object (either inanimate or living) in three dimensions via specialised software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. 3D Animation is the process of generating three-dimensional moving images in a digital environment. Careful manipulation of 3D models or objects is carried out within 3D software for exporting picture sequences giving them the illusion of animation or movement. However, this is completely based on the technique used for manipulating the objects. The procedure of generating 3D is sequentially categorised into three main sections and these are modelling, layout and animation and rendering. Modelling is the phase that describes the procedure of generating 3D objects within a certain scene. Layout and animation phase describes the process followed for positioning and animating the objects within a certain scene. Lastly, rendering described the end result or output of completed computer graphics.
