What is computer animation?

Computer animation can be described as an artistic form that includes reviving static images using computer technology. Animation in this form can apply to pictures on a computer or to those in a movie. When computer animation is used for movies, it is often called computer -generated images (CGI).

To create a computer animation, still or a different image, it will appear for the first time. With regard to speed, this image is replaced by another picture. The new picture is very similar to the first, but has been changed in several small ways. Each subsequent image changes slightly. This combination of rapid image replacement and slight changes in images creates the illusion of movement. Although computer technology is used for computer animation, the technique of creating the appearance of movement is the same as the technique used for television and film animation.

You want to understand how movement is created using computer animation, consider an empty screen. Now Imagine Person DraseLena on the left side of the screen. Then imagine that the screen is empty again, and the next time you see a picture of the person, it is located just a little to the right of its initial position. Once again, the screen is blinded and the person is moved a little more to the right. At high speed, this slight movement of the image will lead to the appearance of smooth movement to the right.

speed is the key to the success of computer animation. In order to give the illusion of smooth movement, complete images, often called images , must be displayed at least 12 images per second. At smaller speeds, the human eye is able to detect a certain amount of jerk. However, it is interesting that there is no advantage for displaying images at speeds of 70 frames per second or more, as there is no significant improvement in perception of movement at speed so high.

when an IS animation created using conventional hand -drawn methodsIt is not unusual to use 15 frames per second. This is done to economize the amount of drawings necessary to create animation. However, computer animation is often used to create more realistic looking pictures. Therefore, it is usually necessary to use multiple images per second.

To create a computer animation, a computer and special animation software are required. Today, there is a wide range of animation software on the market, while prices differ according to the intended use. Generally, animation software is designed for a beginner to enjoy entertainment or for simple animation, less expensive. Software for more professional animation is not only more expensive but also more complex. However, even the most basic animation programs are able to create some amazing animations.
