Animation Design Steps
• Storyboard Layout
• Object Definitions
• Keyframe Specification
• Generation of in-between frames
CS2401 - Computer Graphics 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 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 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 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

Other Tasks
• Motion Verification
• Editing and Production
• Synchronization of Sound Track

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

Raster Animations
• On raster systems, we can generate real-time animation in limited applications using raster operations.
• Simple 2D/ 3D transformations
• Color Table Transformation

Key-frame Systems• Morphing
– Transformation of object shapes from one form to another
