The document outlines the steps involved in animation design, including storyboard layout, object definitions, keyframe specification, and the generation of in-between frames. It discusses concepts like motion verification, editing, and synchronization of sound, as well as the advantages of using computer solutions for various animation tasks. Additionally, it covers raster animations and key-frame systems, including morphing techniques.

- 2. Animation Design Steps • Storyboard Layout • Object Definitions • Keyframe Specification • Generation of in-between frames CS2401 - Computer Graphics 2
- 3. Storyboard • Storyboard is an outline of the action • Defines the motion sequence as a set of basic events that are to take place CS2401 - Computer Graphics 3
- 4. Object Definition • Object definition is given for each participant in the action • Basic shapes, such as polygons or splines • Associated movements for each object are specified along with the shape. CS2401 - Computer Graphics 4
- 5. Keyframe • Keyframe is a detailed drawing of the scene at a certain time in the animation sequence • Each object is positioned according to the time for that frame CS2401 - Computer Graphics 5
- 6. In-betweens • In-betweens are the intermediate frames between the key frames • Determined by the media to be used to display the animation – Film : 24 fps – Graphics Terminals : 30 to 60 fps CS2401 - Computer Graphics 6
- 7. Other Tasks • Motion Verification • Editing and Production • Synchronization of Sound Track CS2401 - Computer Graphics 7
- 8. General Computer Animation • Some steps in the development of an animation sequence are well-suited to computer solution. – Object Manipulation and Rendering – Camera Motions ( Zooming, Tilting etc..) – Generation of In-betweens – Store and Manage Object Database CS2401 - Computer Graphics 8
- 9. Raster Animations • On raster systems, we can generate real-time animation in limited applications using raster operations. • Simple 2D/ 3D transformations • Color Table Transformation CS2401 - Computer Graphics 9
- 10. Key-frame Systems • Morphing – Transformation of object shapes from one form to another CS2401 - Computer Graphics 10
- 11. Morphing CS2401 - Computer Graphics 11
