CS4624 Animation

Animation Types

• Motion, dynamic action: Animation is simulating motion through computer displays.
  
• Cel animation: Motion is shown through a sequence of
  stills, with small variations from one to the next. Often the stills are artificial or cartoon objects, or of some virtual world, or some synthetic construction from computer graphics.
  
• Paths: Motion can be specified by identifying objects in the image that will move, and showing their path of motion, such as by indicating endpoints and arcs or curves
  or a sequence of intermediate points on the path.
  
• Sprite: Sprite animation refers to one or more independent objects that move from still to still, perhaps leaving everything else the same. Several sprites can operate simultaneously and differently. Sprites are often thought of as animate or active.
  
• Compression: Compression is often effective since there is a great deal of intra-frame redundancy (e.g., regions of uniform color where run-length encoding works well), and a great deal of inter-frame redundancy (with, say, only the sprites moving).
