A Quick Reference In Computer Animation Technology

To be able to give life to something created through illusion of thoughts that cannot move itself through use of a computer is defined as computer animation technology. The birth of computer technology gave rise for many of us to fully appreciate its high speed efficiency and the tedious hours of doing things manually. The introduction of computer animation technology has benefited animators particularly in trying to cope with the fast development in new technologies such as the release in the market scene of digital television, virtual reality games and multi media products. With these developments, viewers will try to look for more ways to interact with new programs. Computer animation technology has provided several processes of creating animations from creating digital frames, painting systems, photographing and scanning. With these technologies, any changes or revisions on the animation can be easily edited or additions can be made. Examples of these processes are 'in-betweening', painting systems,
camera stands and edit. In-betweening is the process of creating intermediate frames to fill in the action from key scene to key scene. Under the traditional process, it takes 23 cels for an animator to put colors into animated cels. Computer painting tends to increase animator painter production and eliminates the chances of errors.
Computer painting also uses a coloring or filling process where the artist selects the color and pixel. It allows the system to adjust pixel setting which are same in color to the newly selected color. In creating animation, once the frames are painted, they are ready to be filmed. Under the traditional process, the animation stand is positioned where both the cels and the camera implement to allow the layers of cels and the camera to move independently. With computers, animation stand and the camera are simulated. The computer controls this virtual camera in three-dimensional space, while series of two-dimensional images or cels in the computer's memory are given focused. Another technology in computer animation is the realistic three-dimensional scene called rendering.

Information is provided giving a detailed description of the objects that is required from the scene, together with the camera's specifications. For a photographic-like images, the computer calculates the viewers' perspective of the image, the visible objects and surfaces. It also adds shading by determining the available light on each surface, adding reflections and shadows, providing surfaces with textures, patterns, and roughness in order to make objects appear more realistic. Finally, it adds transparency to objects and removes surfaces hidden by other objects. As new technologies evolve, the computer animation process will continue to grow and changes will occur. Likewise, the need for faster and powerful computers may be needed to be able to explore new techniques and provide potential photorealistic effects in the future.
