  1. Chapter 11 ANIMATION • Group Name: Creative Web World • Jose T Barriga • Claudia L. Espinosa • Ranjana Agarwal

  2. Animation adds visual impact to your Multimedia projects and Web Pages • It is possible to animate a whole project or only part of it. • Visual effects are available in most authoroting packages. • Macromedia Director and Adobe Premier have many transition effects.

  3. PRINCIPLES OF ANIMATION • Animation is possible because of a biological phenomenon known as persistence of vision and a psychological phenomenon called phi. • When a person sees an object, it remains chemically mapped on the eye’s retina for a brief time after viewing it. • Our mind perceives this action as a visual illusion of movement.

  4. PRINCIPLES OF ANIMATION • Television uses 30 frames per second. Meanwhile, movies on film are shot at a rate of 24 frames per second. • If you plan to create an animation, first it is useful to create a written script with a list of activities and required objects. Then you can build your sequences and experiment with effects.

  5. CEL ANIMATION • Disney used a series of different graphics on each frame of movie film. A minute of animation may require 1,440 separate frames. • In order to create a movie, they used celluloid sheets for drawing each frame. Today it has been replaced by acetate or plastic. • Cel animation artwork begins with keyframes that are the first and last frame of an action.

  6. CEL ANIMATION • The series of frames in between the keyframes are drawn in a process called tweening. • Tweening an action requires calculating the number of frames between keyframes and the path the action takes. • The penciled frames are assembled and filmed to check smoothness, continuity, and timing. If they are satisfactory, they are inked and painted on.

  7. COMPUTER ANIMATION • Employs the same procedural concept as cel animation. It uses layer, keyframe, and tweening techniques. • The word inks means special methods for computing RGB pixel values so that the images can mix their colors to produce special transparencies and effects. • The smaller the object, the faster it can move.

  8. KINEMATICS • Kinematics is the study of the movement and motion of structures that have joints such as a walking man. • In order to animate a walking step, you need to calculate the position, rotation, velocity, and acceleration of all parts involved.

  9. MORPHING • Morphing is an effect in which one image transforms into another. It is possible not only using still images but also using moving images. • Some examples of products that offer morphing features are Avid’s Elastic Reality, Human Software’s Squizz, Image Ware’s Morph Wizard among others.

  10. MORPHING • The previous figure illustrates how the images of 16 kindergarten children are dissolved one into the other in a continuous compelling motion video. • These morphed images were built at a rate of eight frames per second, and the number of keypoints was held to a minimum to shorten rendering time. • The point you set in the start image will move to the corresponding point in the end image.

  11. ANIMATION FILE FORMATS • The file formats designed to contain animations include Director (.dir, .dcr), Studio Max(.max), Motion Video(.mpeg, .mpg), Compuserve(.gif), and Flash(.swf) among others.

  12. MAKING ANIMATIONS THAT WORK • The most widely used tool for creating multimedia animations for Macintosh and Windows environments is Macromedia;s Director. • If you want to create a rolling ball, you can use Photoshop and Kai’s Power Tools’ Spheroid Designer to do that. • First, create a new blank image file that is 100X100 pixels, and fill it with a sphere.

  13. A ROLLING BALL • The next step is to create a new layer in Photoshop, and place some text on this layer. • Spherize the text using Photoshop’s distortion filter, and save the results. To animate the sphere you need to make a number of rotated images of the sphere.

  14. A ROLLING BALL • Rotate the image in 45-degree increments to create eight images. • You can make a bouncing ball to animate your Web site using GIF89a. • You can also make the ball with a 3-D graphics tool that will shade it as sphere.

  15. A BOUNCING BALL • Then duplicate the ball by placing each copy of it in a vertical line at the ten locations 1,4,9,16,25,36,49,64,81,100. Our goal is to create a separate image file for each location of the ball. • You can also do this construction process with Director or Flash. • You can also add a back ground and other art elements. Then export each frame using the export function.

  16. A BOUNCING BALL • With applications like GifBuilder for macintosh or Gif Construction Set for Windows, you can turn your collection of images into GIF89a animation.
