Computer animation is considered an art. It is the art of making images move using a computer program. The animation can be done in two ways. One is by making cartoon frames in series and then combining it to create a film. Another way of producing animated characters is by making a model and then placing it in the monitor. The position will be recorded and then moved again. The process of placing and recording will be done continuously until the scene is done. A rendering machine is used to produce computer animation wherein images in the frames can be varied. This is done to take some actions of the models involved in the scene. Using of physical models and simply moving the camera is already considered animation. Nowadays, more complicated computer animation is done in many ways, such as the inclusion of a curved trail and applying the law of physics to determine the performance of the models. Visualization also uses animation for sophisticated and time-dependent systems. This is done to determine the current condition of the object.
