Samples and Descriptions

An Important Observation
Back SMYC Forward

The approach used to represent the dynamics (i.e., to animate the visual content) is independent of the approach that is used to represent the (static) visual content.

  • Examples:
    • Flip-Book Animation
    • Movie Film
  • Some Terms:
    • Frame animation
    • The frame rate
Described Dynamics
Back SMYC Forward
  • The Concept:
    • Describe the way the visual "stream" changes over time
  • Approaches:
    • Start with a discrete set of frames and then describe frame-by-frame changes
    • Start with a set of components (i.e., the "participants" in the "action") and then describe component-by-component changes

Terminology for Described Dynamics

  • Sprite:
    • Common Usage - an imaginary being or elf
    • Animation - a discrete piece of visual content that can respond to descriptions of changes
  • Stage:
    • The "component" that sprites act "on"
