What the hells tweening?

• Comes from the term in-betweening, the process by
  which an intermediate frame of animation is
  created by using two key frames (usually drawn
  by the head artist) as references to create
  smoother animation.
• CATs goal is to steal the human tweeners job by
  automating (to the greatest degree possible) the
  process of interpolating frames.

Program Organization

• Two main components CAT and the Server

4
Feature Descriptions

• CAT File simplified model of picture used for
  tweening
• Format Extractor converts an image into a CAT
  file
• Drawing Pad allows the creating of CAT files
  directly
• Player displays the animation sequence created
  with tweened frames at a given frames per second
• Tweener core of the program, configures the
  point arcs that ultimately determine the
  interpolated frames
• Server used to store and organize frame
  sequences, CAT files, and tweening data among
  different animators

5
Technical Target

• Somewhere between shape tweening and morphing
• Motion tweening
• Shape tweening
• Right about here
• Morphing

6
Phase Progression

• For each phase CAT should be able to draw,
  extract, tween, and play the following
• 1. Lines 2. Arcs 3. Colors

7
Implementation

• CAT Java/swing
• CAT files XML
• Server Wishful thinking/force of will
