Animation is considered to be one of the exciting forms of pictorial presentation.Animation consists of three main features picture , motion and simulated. Animation adds visual impact to the multimedia project. Many multimedia applications for both the Macintosh and Windows provide animation tools, but you should first understand the principles to the eye interprets that changes it sees as motion. Most Web animation requires special plug-ins for viewing. The exception is the animated GIF format, which is by far the most prevalent animation format on the Web, followed closely by Macromedia's Flash format.

The animation option of the GIF format combines individual GIF images into a single file to create animation.You can set the animation to loop on the page or to play once, and you can designate the duration for each frame in the animation. There is a place for animation on the Web, however. Simple animation on a Web site's main home page can provide just the right amount of visual interest to invite users to explore your materials. There, the essential content is typically a menu of links, so the threat of distraction is less than it would be on an internal content page. Also, subtle animation such as a rollover can help guide the user to interface elements that they might otherwise overlook. Animation can also be useful in illustrating concepts or procedures, such as change over time. When you have animation that relates to the content of your site, one way to minimize the potential distraction is to present the animation in a secondary window. This technique offers a measure of viewer control: readers can open the window to view the animation and then close the window when they're through.



Animation is possible because of biological phenomenon known as persistence of vision.The object seen through human eye retina seemingly blend together into a visual illusion of movement.

In other words, if you just change slightly the location or shape of an object rapidly enough the eye will perceive the changes as motion. The perception of motion in an animation is an illusion. The movement that we see is, like a move, made up of many still images, each in its own frame.


Because multimedia comes with a high price tag, it should be used sparingly and judiciously.  A significant amount of downsampling and compression is required to create a file that is small enough to be delivered via the Web. In some cases, these compromises may be too significant to warrant the effort. When you are considering adding multimedia to your pages, make sure the technology can meet the demands of your content. You don't want users to spend extra time and energy retrieving files that cannot be illustrative owing to limitations of the technology.

Also be wary of fledgling technologies. Plug-ins that allow users to see new and exciting things using their favorite browser software are constantly being introduced. This is especially true of multimedia; the options for encoding and delivering audio, animations, and video are dizzying. When designers may be tempted to create files that employ the functionality offered by custom plug-ins, they should bear two things in mind. First, the bother and potential confusion of downloading and installing plug-ins will deter many users. Second, it is not prudent to create content in a custom file format that could quickly become obsolete. It is best to create your multimedia content in the standard formats for operating systems and browser software.


There are FOUR main types of animations which are used in multimedia applications.

The first type of animation :2D animation or linear animation, is the simple movement of objects on the screen, generally through linear translation. Multimedia development environments often provide the necessary tools to perform this simple animation procedure.

The original creation of animation :3D animation, however, is very technically and artistically involved, as well as time consuming. Three dimensional objects are created using a mathematical model. Each object may be shown in various views, giving the user a realistic sense of third dimension.


Motion to appear smooth a minimum of 15 frames per second generally required.

There are two dimensions



It involves techniques as well




Although 2D animation can be effective in enhancing a multimedia title, 3D animation takes the entire experience of multimedia to another level. Three dimensional animation is the foundation upon which many multimedia CD games and adventure titles are constructed. Top selling products such as Myst and WarCraft use 3D animation to bring the user into the setting and make him or her seem a part of the action.

Creating 3D animation is considerably more complex than 2D animation and involves two steps : modeling and rendering before the real animation takes




There are two kinds of special effects




Morphing is useful not only in showing how two images blend together, but also in showing how an image might change over time.

Photo Morph, Hijact Morph, and Elastic Reality are examples of programs than can produce quite sophisticated morphing animations.


Warping is a related special effect that allows you to manipulate a single image. For example, you could stretch a facial feature to change a frown into smile.


Virtual Reality

Virtual Reality (VR) attempts to create an environment that surrounds the user so that he or she becomes part of the experience. The term Virtual Reality has been used to describe various types of applications, some that are more experiential than others.


It is nearly impossible to construct a multimedia presentation that will be accessible by every user on the World Wide Web. Whenever you put multimedia content on your Web pages you potentially shut out users. For example, vision-impaired users cannot see content such as graphics, video, or animations. To access visual content, they need a text alternative that can be spoken by a screen reader. Hearing-impaired users rely on content they can see, and so they need a visual alternative to any audible materials. Initiatives such as Section 508 and the Web Accessibility Initiative (WAI) have produced guidelines and mandates requiring that nontext content be rendered in an alternate format that is accessible to disabled users, such as text captions for audible content and text descriptions of visual content. This is why it is particularly important when planning for multimedia content to consider users with disabilities: both technology-disabled users who are connecting to the Internet via slow modems on outdated machines and physically disabled users for whom multimedia content may be out of reach.


"Humankind has always been fascinated by moving images. The desire to make pictures move has provoked some of the most innovative developments in the fields of science and technology during the twentieth century" (Bendazzi, 1994). Animation had made fantasy of human kind come true. It has brought a drastic change in the present world. Every sector in particular field has a production.All media communicate most effectively in their language of animation.

"Animation is everything from Pinocchio learning to walk,skeletons fighting classical heroes, a pumpkin king ditching Halloween for chrismas" (James Clarke 2004).Animation brings stationary objects into motion.Movement should be used for essential communication.In animation anything is possible.Animation brought pictures to life.Animation is used in video games,filims,robotics.

"Animated worlds need logic, consistency and boundaries".(Bryce Hallett, 2008) In animation ,idea development must include visual exploration. To achieve animation write for action first.In animation,any real or imaginary, can be made into a character. It has two levels, basic and advanced.

The merit of the computer animation-based activities has also been questioned(IEEE journal on essential animation 1998). Most of children at homes use their computers for playing games, doing homework, chatting with friends which reduces their interest in other co-curricular activities.But there are also positive side of animation.with the help of animation children interaction increases which helps them to learn in a affective way.
