Definition of Animation

To begun, we will define the term « animation » because it’s a very vague term

The animation is to give the illusion of movement with the help of a sequence of images. These images can be drawn, painted, digital, photographed.

We have two aspect of this animation which are:

- Images by images: We must represent each movement phase performed and saved image by image whatever the system of representation chosen, whatever the means employed to acquire, whatever finally the restitution process visual animation

- Frequency of restitution: images are returned on a regular frequency basis enough for the brain and the phenomena of inertia within the vision, whose persistence reticence play their role in the illusion. In cinema, the minimum frequency was set at 12 fps. But to avoid an unpleasant flicker frequency of 16 frames / second is the absolute minimum.
