Essay On Computer Animation

Computer animation (also called digital animation) is the technique of creating moving images via the use of computers. Increasingly, the graphics are created in 3D, but 2D graphics are still used extensively for slow connections and real-time applications that need to render faster.

Sometimes the purpose of animation is the computer itself, others may be another means, like a movie. The designs are made with the help of design software, modeling, and finally rendering.

To create the illusion of movement, a displayed image is quickly replaced by a new image in a different frame. This technique is identical to the way that achieves the illusion of movement in movies and on television.

For 3D animations, objects are modeled in the computer

In biped or quadruped characters, many parts of the skeleton of the character corresponding to the bone. Animation with bones are also used to animate other things, such as facial expressions, a car or other object that want to provide movement.

In contrast, another type of animation would be more realistic motion capture, which requires an actor wear a special suit fitted with sensors, their movements being captured by a computer and later incorporated into the character.

For 3D animations, frames must be rendered after the model is completed. For 2D vector animations, the rendering process is key to the outcome. For recordings taped in advance, the frames are converted to a different format or medium as a film or digital video. The frames can be rendered in real time, while these are presented to end users. The animations for broadcast via the Internet at low bandwidth (eg 2D Flash, X3D) use programs on the user's computer to render in real-time animation as an alternative to transmission and pre-loaded animations for high-speed links.

A simple

More complex transformations of object properties such as size, shape, or color light effects, and rendering calculations required by the computer instead of a simple procedure to duplicate or re-draw pictures.

Explanation

To fool the eye and brain to think that someone is watching a moving object, the images should be shown to about 12 frames per second or faster (a frame is a complete image). With speeds up to 70 frames / second, you will not notice an improvement in realism or smoothness in the movement of the image due to the way the eye and brain process images. At speeds under 12 frames / sec most people can detect a flicker in time to display the sequence of images and drop the illusion of realistic movement.

Conventional animations made by hand, typically use 15 frames / second in order to decrease the amount of drawing required, but this is usually accepted because of the nature of cartoons. Therefore, to create a realistic computer animation, it requires a higher number of frames /
