Persistence of Vision
Refers to the way our eyes retain images for a split second longer than they actually appear, making a series of quick flashes appear as one continuous picture.
Frame by Frame Animation
what appears to be continuous motion is actually a series of many different frames Each frame shows the same graphic with a tiny amount of position change to simulate motion.
Computer Assisted Animation
The computer is used to make the animation process quicker and easier. It usually involves 2-D images that can be hand-drawn and scanned into the computer or drawn directly into the computer using graphics tablets.
Computer Generated Animation
All images, objects and animation are created on the computer.Typically uses 3-D images. It adds two steps to the animation process.
Modeling
Process of creating a wireframe structure of the 3D objects and scenes
Rendering
Process of applying colors, textures, shadows, Transparency, etc. to create the final image or animation Motion capture techniques can be used to animate objects.
Path Animation
Also called vector animation. An object follows a path which is a line, or vector, inserted by the animator.
Morphing Animation
A shortened term for metamorphosing. A technique in which one image is gradually turned into another.
Programming or Scripting Based Animation
Requires knowledge of a programming or scripting language. Created by using scripting languages such as Javascript.
Rollovers
Also called mouseovers. When the mouse is moved over an image, it changes to a different image so quickly that it looks as if the change has occurred in a single instant.
Stop Motion Animation
Process of manipulating real-world objects and photographing them one frame at a time. Very popular method with the film industry until computer generated imagery became possible. Now used mainly in clay animation.
Stage
The part of the animation program window where the animation's content is composed and manipulated.
Frame
a single still image in a video or animation
Keyframe
Shows where the key (most important) actions occur.
Timeline
The part of the animation program window that organizes and controls an animation's content over time using layers and frames.
Library
Used to store frequently used graphics, movie clips, and buttons.
Playhead
The vertical red marker in the timeline that shows which frame is the current frame when previewing an animation.
Scrubbing
Dragging the playhead across the timeline in order to preview an animation.
Tween(ing)
An animation process in which frames are created between the keyframes that are needed to create the illusion of movement.
Compression
The process of reducing the space required to store data by efficiently encoding the content.
MP3
A standard format for music files sent over the Internet that compresses music.
WAV
The standard format for sound files on Windows-based computers.
Executable File
A program file that can cause an application to run on your computer when it is opened.
Plug-in
A hardware or software application that adds a specific feature to a browser.
Standalone Player
A program that can work independently of a browser to play audio or video files.
Bandwidth
The amount of data that can be transmitted over a network in a given amount of time.
Streaming
A procedure for transmitting media files so they can start playing as soon as a computer begins receiving them rather than waiting for the complete files to download first.
Streaming Rate
The rate in frames per second at which the movie is downloaded.
Playback Rate
The rate in frames per second at which the movie plays.
