Animation
This document provides an overview of animation, including its definition, categories, techniques, principles, and file formats. It defines animation as bringing images to life by varying visual properties over time. There are two main categories: cell animation involving hand-drawn frames, and computer animation which can be 2D or 3D. Basic animation techniques include drawn, cut-out, model, and computer animation. Principles like squash and stretch, anticipation, and timing are described. Common file formats and animation software are also listed.

- 3. Introduction to Animation Theword “animation” derives from “animate,” which means “to bring to life”. Thus when a multimedia developer wants to bring an Image to life, animation is used. “Animation is the process resulting time-varying visual effects of motion, shape, color and so on.”
- 4. Why Do WeSee Images As Moving ? The Persistence of Vision Theory Our brain holds onto an image for a fraction of a second after the image has passed. If the eye sees a series of still images very quickly one picture after another, then the images will appear to move because our eyes cannot deal with fast-moving images.
- 5. Effects On PictureDuring Animation In Animation, you get moving images when the pictures change in some way. Here are some ways in which pictures can change :- Change in Size Change in Position Change in Angle Change in Color Change of Shape
- 6. Categories Of Animation Animationdeals with graphics drawn by hand or by animation software. Depending upon the techniques used to create and manage the frame. There are two broad categories of animation :- 1. Cell Animation 2. Computer Animation :- a) Computer Assisted (two-dimensional) animation b) Computer Generated (three dimensional ) animation
- 7. Animation Functions Zooming Tilting Panning Tweening Morphing
- 8. Zooming If we fixthe window on an object but reduce or increase its size, the object would appear bigger (zoom in) or smaller (zoom out), respectively.
- 9. Tilt (camera) Tilting isa technique in which the camera is stationary and rotates in a vertical plane (or tilting plane). Tilting the camera pitch rotation. results in a motion similar to someone nodding their head "yes" or to an aircraft performing a pitch rotation.
- 10. Panning A rotation ina horizontal plane is known as panning (yaw rotation). Tilting the camera results in a motion similar to yaw rotation someone nodding their head “no" or to an aircraft performing a yaw rotation.
- 11. Tweening Traditional animation sequenceis created by two types of artists :- 1. the lead artists or experts who draw those frames where major changes take place within the sequence, called key frames. 2. assistants draw a number of frames in between the frames, process is called tweening.
- 12. Morphing Transformation of objectshapes from one to another is called morphing.
- 13. Animation Techniques There arefour basic techniques used in animation. These are:- 1. Drawn Animation 2. Cut-out Animation 3. Model Animation 4. Computer Animation
- 14. Drawn Animation This coversany form where one drawing is replaced by another in a sequence. Each drawing is slightly different from one before. Disadvantages:- It takes a very long time to film from start to finish and is expensive needing many animators to complete the work.
- 15. Cut-out Animation This coversany form where cut-out shapes are moved around or replaced by other cut-out. Flat objects like buttons, matchsticks and string can also be used in this form of animation. Disadvantages:- It is difficult to have more than one or two cut-outs moving at the same time.
- 16. Model Animation This involvesthe filming of puppets or any form of three-dimensional models. Disadvantages:- This type of animation needs a lot of time and hard work. The makers of „James and the Giant Peach‟ were only able to complete 45 seconds of model animation a week, 10 seconds a day. This was because each puppet had so many joint.
- 17. Computer Animation This refersto drawing of three dimensional models and sets on the computer. Images can be scanned into the computer using digital photography or made within the computer itself.
- 18. 11 Basic Principleof Animation 1. Squash and stretch 2. Anticipation 3. Staging 4. Straight ahead action and pose to pose 5. Follow through and overlapping action 6. Slow in and slow out 7. Arcs 8. Secondary action 9. Timing 10. Exaggeration 11. Appeal
- 19. 1. Squash andStretch Defining the rigidity and mass of an object by distorting its shape during an action
- 20. 2. Anticipation Preparation foran action Example: Goofy prepares to hit a baseball.
- 21. 3. Staging Presenting anidea so that it is unmistakably clear
- 22. 4. Straight AheadAction and Pose- to-Pose Action 1. Straight Ahead Animator start from first drawing in the scene and draw all subsequent frames until the end of scene. 2. Pose-to-Pose Animator plans actions, draws a sequence of poses, in between frames etc.
- 23. 5. Follow Throughand Overlapping Action The termination of an action and establishing its relationship to the next action Example: Luxo Jr.‟s hop with overlapping action on chord.
- 24. 6. Slow inand Out
- 25. 7. Arcs • Visualpath of action for natural movement. • Makes animation much smoother and less stiff than a straight line.
- 26. 8. Secondary Action Theaction of an object resulting from another action Example: Body movement is the primary action, facial expression is the secondary action
- 27. 9. Timing andMotion Examples: 1. Timing: tiny characters move quicker than larger ones. 2. Motion: can define weights of objects.
- 28. 10. Exaggeration Accentuating theessence of an idea via the design and the action Example: Luxo Jr. made smaller to give idea of a child.
- 29. 11. Appeal Creating adesign or an action that the audience enjoys watching
