Animation is a field of art or science that has the capability to impart life and zeal to non living characters. Basically it is based on the phenomenon of persistence of vision that allows the visual illusion of the objects. It is a phenomenon of an eye in which an image continues to appear in one’s vision after the exposure to the original image has ceased. This happens for about one twenty-fifth of a second. In early days animation was restricted to only hand drawings. But with the advent of technological knowhow animation has got a new face that is known as two dimensional and three dimensional animations. A three dimensional animation is far better than two dimensional. It adds more vigor and Bvivacity to animation. Animation is simulation of movement created by a series of pictures or frames. It starts with drawing independent pictures and putting them together in a frame to form the illusion of continuous motion. Two dimension means that the picture is drawn with help of two coordinates of geometry. These are designated as x (horizontal) coordinate and y (vertical) coordinate. 2D is flat which means that if a picture is turned to the side then it becomes a line. Whereas 3D includes an extra dimension known as z coordinate which stands for rotation and depth. The basic difference between 2d and 3d can be illustrated by drawing a rectangle and a cube. Rectangle is a 2D figure whereas cube is a 3D figure. 3D presents the object from every possible direction like in real life. 2D bitmap or vector graphics are used to create 2D animation figures.
Animation is a type of optical illusion; it is the process by which we see still pictures move. It involves the appearance of motion caused by displaying still images one after another at the rate of 24 pictures per second. The most common method of presenting animation is as a motion picture or video program, although several other forms of presenting animation also exist.
Animation is used for entertainment purposes. In addition to its use for entertainment, animation is considered a form of art. It is often displayed and celebrated in film festivals throughout the world. Also used for educational purposes, animation has a place in learning and instructional applications as well.
The most obvious difference between the two genres of animation is of course the three dimensional characteristics or the appearance of depth. While 2D animation is a flat animation and all the actions happen in the x-y axes, 3D animation includes an extra dimension and that is the z axis. The working method for creating 2d cartoon characters and 3d animated figures are entirely different. While in 2D animation the process of cartoon character creating involves sketching the character from different sides with the help of onion skin tools. Creating a 3d model requires digital modeling and is more similar to sculpting a character than drawing one. An animator working in 3d dimensional environment constantly has to be aware of how his/her changes to the model side view affect the front view or any other view for that matter. Creating a perfect looking model is a difficult task since all the different views have to be taken into the consideration. Creating a 3d model is often based on a pre-made two dimensional sketches of the character from different views. After the model is created a material has to be assigned to it and the model has to be textured properly. Although the process of character creating for 3D animation is usually taking more time than 2D character creation, the process of creating the animation itself can be considered easier by many animators. In 2d animation the animation is created by drawing almost every frame of the animated movie. In 3D , the animation is created by changing the poses and the placement of already created 3d models. The created scene can be viewed from different angles and by that it is easier and faster to create an illusion of change in the environment.
Various techniques that are acclimated in creating 2D abstracts are morphing, twining, onion skinning, Anime, and amid rotoscoping. Admitting 3D action involves agenda clay of characters. Various accomplish that are complex in 3D action are appearance sketching, appearance modeling,, Anime, arena building, texturing, abating and camera setup, rendering, abating and camera setup, rendering, alteration and bond etc. Other techniques, Anime that can be activated are the use of algebraic functions, apish fur or hair and the use of motion capture. In this way we can abstract greater use of multimedia through 2D and 3D animation.
