Animation

 Classical animation
Classical animation is drawn animation and is the most traditional of all animation techniques. Even though cut out, sand and colour animation also involve the creation of the animation aslo involve the creation of the animation on a flat plane of images which are modified little by little continuously and the changes captured by a stop-frame camera pointing down onto the horizontal frame, they are mere extensions to the traditional drawn animation.
In classical animation, the drawings on papers are well drawn,
therefore, it is a very tedious and time consuming progress as the rentire sequence is drawn and painted frame by frame painstakingly with high precision. It requires accurate planning, timing and co-ordination that's why Classical Animation often involves many people working as a team.
Materials required for classical animation:
a) Pencils/ Markers/ Erasers
b) Ring file
c) A4 size paper
d) Lightbox
 Clay Animation
Clay animation is one of many forms of stop motion animation. Each animated piece, either character or background, is made up of a malleable substance, like Plasticine clay. The portmanteau term "Claymation" is a registered trademark in the United States, registered by Will Vinton in 1978 to describe his clay animated films. While the word is not considered a genericized trademark, it has become a trademark which is often used generically in the US, and is the predominent term in the UK, to refer to any animation using plasticene like substance.
All traditional animation is produced in a similar fashion, whether done through cel animation or stop-motion. Each frame, or still picture, is recorded on film or digital media and then played back in rapid succession. When played back at a frame rate greater than 10-12 frames per second, a fairly convincing illusion of continuous motion is achieved. While the play-back feature creating an illusion is true of all moving image (from zoetrope, to films to videogames), the techniques involved in creating CGI are generally removed from a frame-by-frame process.
In clay animation, which is one of the many forms of stop motion animation, each object is sculpted in clay or a similarly pliable material such as Plasticine, usually around a wire skeleton called an armature. As in other forms of object animation, the object is arranged on the set (background), a film frame is taken and the object or character is then moved slightly by hand. Another frame is taken and the object moved slightly again. This cycle is repeated until the animator has achieved the desired amount of film. The human mind processes the series of slightly changing, rapidly playing images as motion, hence making it appear that the object is moving by itself. To achieve the best results, a consistent shooting environment is needed to maintain the illusion of continuity. This means paying special attention to maintaining consistent lighting and object placement and working in a calm environment. Producing a stop motion animation using clay is extremely laborious. Normal film runs at 24 frames per second (frame/s).
 3D Animation
3D animation are the animations that use a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing. Despite these differences, 3D animations rely on many of the same algorithms as 2D animations in the wire-frame model and 2D computer raster graphics in the final rendered display. 
In computer graphics software, the distinction between 2D and
3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques. 3D animations are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical representation of any three-dimensional object (either inanimate or living). A model is not technically a graphic until it is visually displayed. Due to 3D printing, 3D models are not confined to virtual space. A model can be displayed visually as a two-dimensional image through a process called 3D rendering, or used in non-graphical computer simulations and calculations.
 Flash Animation
A Flash animation or Flash cartoon is an animated film which is created using Adobe Flash animation software and often distributed in the .swf file format. It can be created in Flash or with other programs capable of writing .swf files. The term Flash animation not only refers to the file format but to a certain kind of movement and visual style which, in many circles, is seen as simplistic or unpolished.
However, with dozens of Flash animated television series,countless more Flash animated television commercials,
and award-winning online shorts in circulation, Flash animation is enjoying a renaissance.
Flash animations are typically distributed by way of the World Wide Web, in which case they are often referred to as Internet cartoons, online cartoons, or webtoons. Web Flash animations may be interactive and are often created in a series. A Flash animation is distinguished from a Webcomic, which is a comic strip distributed via the Web, rather than an animated cartoon.
