Computer Graphics Animation

Computer Graphics Animation - It is a subfield of computer graphics and animation. It's increasingly created using 3D computer graphics, 2D computer graphics but are still widely used for low bandwidth and faster real-time rendering needs used. Sometimes the goal of animation is the computer itself, but sometimes the target is a different medium, like film.

It is also known as CGI (computer generated imagery or computer-generated imaging) is called, especially when used in films. To create the illusion of movement, an image on the computer screen then quickly replaced by a new image that is similar to replacing the previous image is displayed, but shifted slightly.

This technique is the same as the illusion of movement is achieved with television and feature films. Computer animation is essentially a digital successor to the art of stop-motion animation of 3D models and frame-by-frame animation of 2D illustrations. For 3D animations, objects (models) on the computer monitor (modeled) and 3D figures are built rigged with a virtual skeleton. For 2D-motion animation to be separate objects (illustrations) and separate transparent layers are used, with or without a virtual skeleton.

Then the limbs, eyes, mouth, clothes, etc. the figure by the animator on key frames moved. The differences in appearance between key frames are automatically calculated by the computer in a method of tweening or morphing known methods. Finally, the animation is shown. For 3D animations, all images calculated after modeling is completed. For 2D vector animations, the rendering process, the key frame illustration process, while tweened frames are rendered as needed.

For pre-recorded presentations, the rendered images in a different format or media such as film or digital video transmission. The frames can also be played back in real time, as they presented the end-user audience. Low bandwidth animations transmitted via the Internet (eg 2D Flash, X3D) use common software on the end-user computer in real time as an alternative to streaming or preloaded high bandwidth animations to render.
