CAT Project(Computer Aided Tweening) Andrew Yurovchak
What the hell’s 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. • CAT’s goal is to steal the human tweener’s job by automating (to the greatest degree possible) the process of interpolating frames.
Program Organization • Two main components: CAT and the Server
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
Technical Target • Somewhere between shape tweening and morphing Motion tweening: Shape tweening: Right about here Morphing:
Phase Progression For each phase CAT should be able to draw, extract, tween, and play the following: 1. Lines 2. Arcs 3. Colors
Implementation • CAT: Java/swing • CAT files: XML • Server: Wishful thinking/force of will
