Animation in Computers

An animation is defined as a visual change in a scene with respect to time. The visual change in the scene is not only associated with the change in the position of the object, but also with its shape, color, transparency, structure and texture. An important point about animation is that it usually signifies the hand drawn or artificially drawn sequence of images, which contrasts to the movies where actors' performances with real-world scenes are recorded. In early times, animations were made by hand by drawing every scene one by one on paper and then painted.  If you have any concerns pertaining to in which and how to use Free Models, you can get in touch with us at our web site. This method was obviously very troublesome and time-consuming. Nowadays, the use of computer technology has made the animation process progressively simpler and more powerful. The process of drawing images and playing them back at a high speed with the help of computer software in order to create an illusion of movement is referred to as computer animation. The illusion of movement is created by displaying an image on the computer screen, then quickly replacing it by a new image, which is similar to the previous image, but shifted slightly.

The field of computer animation is a subset of both computer graphics and animation technologies. Computer animation is generally achieved through a series of geometric transformations-scaling, translation, rotation or any mathematical technique-to produce a sequence of scenes. In addition, the animation can be produced by varying any of the following:

Camera parameters: It involves the camera position with respect to the object, distance from the object, orientation, and focus.

· Lighting conditions: It involves direction and color of light, number of lights, and so on.

These days computer animation is widely used in the entertainment industry for producing motion pictures, cartoon movies, and video games. In addition, it is being used in education and training, industrial applications, virtual reality systems, advertising, scientific visualization and many engineering applications.
