The persistence of vision is when the human eye sees an object for a short time after it has disappeared. This is used in animation so that objects appear to move. It means that separate diagrams with slight changes in motion do not appear jerky

Flip Books
A slightly different diagram showing motion is put on each page. When the book is flipped, animation appears smooth.

Flash/Key Frame Animation
Flash is a piece of software used to create interactive and animated websites. Key frames are the starting frame and the finishing frame in animation. The software fills in the frames between the two key frames. This is called tweening

Advantages of Animation in Commercial and Educational Environments
-It can help explain a difficult concept (e.g. the greenhouse effect, the nitrogen cycle etc.) -It can be used to entertain young children -It can attract users to the website -It can make learning fun for young children

Disadvantages of Animation in Commercial and Educational Environments
-Good animation can be expensive to produce -It can distract users away from the content or the message being given -On a website, it can take a while to load which can put off some people

Storyboards
Explaining how an animation will work is quite difficult. Storyboarding provides a way of communicating visual ideas. It is a series of sketches showing the layout of animations in a multimedia website of presentation.

Mood Boarding
A mood board is a compilation of elements that will give the look and feel of the animation, website or multimedia product. It can include such things as examples of proposed types of animations, colour palettes, font styles etc.

Frame Rates
In an animation, each unique image used in an animation is called a frame. The frame rate is the frequency at which the frames appear on the screen. The greater the frame rate, the better the quality of the movement of the items in the animation.

Looping
Looping is used when you want a motion to be repeated over and over

Vector Animations
The motion is controlled by vectors rather than pixels. Adobe Flash produces vector based animations

Bitmap Animations
The arrangement of bits on the screen changes in some way and a new bitmap is produced

Claymation
A form of stop motion using materials such as clay or plasticine. Models are created and photographed after slight movements are made. Thousands of frames are created. Wallace and Gromit films are examples.

Pixilation
When you enlarge a bitmap image you start to see individual pixels. This is sometimes done deliberately for example in police programmes the maker doesn't want you to see a criminals face for legal reasons.

Rotoscoping
A piece of film with movement of live actors is drawn over so as to get an animation effect with realistic movement. Once the outline of the live actor has been captured, an artist can fill in the rest of the image.

Tweening
This is where you create a start frame and an end frame and the computer generates all the inbetween frames so tat the start image changes into the final image

Onion Skinning
A technique used in animation where several frames in animation are superimposed over each other. This allows the animator to keep track of the motion so they have a better idea where to create the next frame.

Grouping
Grouping images is often done so that they are treated as a single image rather than separate ones. This makes it easier to move and size them.
17 of 19
Cloning
Often in animations you need several items of the same thing (e.g. trees, people, cars, etc.). Rather than create each one from scratch, it is easier to create one and copy it. The copies are identical and are called clones.

Backdrops
This is the scenery against which the characters in the animation appear. For example, an animation of a talking cat might have the contents of a room for a backdrop.
