Computer Animation
Term | Definition |
---|---|
Persistence of Vision | The way our eyes retain images for a split second longer than they actually appear. |
Frame-by-Frame Animation | Rapidly displaying images, or frames, in a sequence to create the optical illusion of movement. |
Computer Assisted Animation | Usually involves 2D images. The images are positioned into keyframes containing the most important movements. Tweening is then performed by the computer to create images between keyframes. |
Computer Generated Animation | All images, objects and animations are created on the computer. Typically uses 3D images. Adds two steps to the animation process. |
Path Animation | Also called vector animation. An object follows a path which is a line, or vector, inserted by the animator. The computer calculates the correct position of the object as it moves along the path and generates the frames to create the animation. |
Morphing Animation | Changing one image into another. The transformation of one thing into another. |
Programming or Scripting-Based Animation | Requires knowledge of a programming or scripting language. Example: Rollover or Mouseover |
Rollovers | 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. Then the frames are put together to make a movie. |
Stage | The part of the animation program window where the animation's content is composed and manipulated. |
Frame | Holds the content that the movie displays or plays at that point in time. |
Keyframe | Shows where the key actions occur. The frames you create. |
Timeline | The part of the animation program window that organizes and controls an animation's content over time using layers and frames. |
Library | Stores frequently used graphics, movie clips, and buttons. |
Playhead | Vertical red marker in the timeline that shows which frame is the current frame. |
Scrubbing | Dragging the playhead across the timeline in order to preview the animation. |
Tweening | The images between keyframes. |
Compression | The compression process removes sounds that humans can't hear. |
MP3 | A standard format for music files sent over the Internet that compresses music or other types of audio. |
WAV | The standard format for sound on computers running the Windows operating system. WAV files produce high-quality sound and generate large file sizes. |
Executable File | Bundles both the animation and the program to play in a single file. |
Plug-in | A program that works with the browser to expand its capabilities. |
Standalone Player | A separate program that can play video and audio files without the browser software being open. |
Bandwidth | The amount of data that can be transmitted over a network in a given amount of time. |
Streaming | A technique for transferring audio and video files over the Internet as a continuous stream of data. |
Streaming Rate | The rate in frames per second at which videos can be downloaded or transferred to a computer. |
Playback Rate | The rate in frames per second at which the video plays. |
