So What Is Animation ? / Computer Animation

This technique is most defiantly the hardest but most advanced Animation technique.


In the simplest terms, :s Computer Animation compromises a variety of techniques, the unifying factor being that the animation is created digitally on a computer.


Computer animation is almost a digital version of stop motion animation, still using the frame by frame process to animate of 2D illustrations.
To create the illusion of movement, an image is displayed on the computer screen and repeatedly replaced by a new image that is similar to the previous image, but advanced slightly in the time domain (usually at a rate of 24 or 30 frames/second). 
This as guessed gives a 'smoooooth' illusion of movement ! 
But the negative of this technique, would be that it can take (in comparison with other techniques I've looked at) a very long time for a 20second video.
