Cel Animation - Computer Animation

Making an animation by using this method, all characters are drawn on a separate piece of transparent paper. Also a background is drawn on a separate part of opaque paper. After that, as it comes to shooting the animation, the various characters are overlaid upon top of the background in all frames. This technique also saves time in such the artists do not have to draw in whole frames, although rather just the parts that require to change as particular characters, yet separate parts of a character's body are put on separate pieces of transparent paper. For further knowing about this, let us have an illustration. As you want to demonstrate that an aero-plane is flying. You can sketch an aero-plane on a transparent sheet and on the other opaque sheet you can have clouds. Then, along with the opaque sheet like a background you can shift the transparent sheet over it that gives the feeling of flying aero-plane.

Such traditional methods were extended to the era of computer animation techniques and thus various animation systems are developed. We cannot say that technique is better as various techniques are used in various situations. Actually all these animation techniques are huge, although they are most useful as all of them are used together. Cel animation through itself would not assist out much if it wasn't for key frames and being capable to distribute the workload across several people. Here, let us also discuss the computer animation techniques that are in broad use, two of the classical computer animation techniques are 'frame' animation and sprite animation.
