Animation

  1. 1. Animation By: Abegail S. Comandao College of Computer Studies
  2. 2. Animation <ul><li>Is the rapid display of a sequence of images of 2-D or 3-D artwork or model positions in order to create an illusion of movement. </li></ul><ul><li>An optical illusion or motion due to the phenomenon of persistence of vision, and can be created and demonstrated in a number of ways. </li></ul>
  3. 3. Motion Picture or Video Program <ul><li>Most common method of presenting animation although several other forms of presenting animation also exist. </li></ul>
  4. 4. Computer Animation <ul><li>A.k.a. Computer Generated Imagery animation </li></ul><ul><li>Art of creating moving images with the use of computers. </li></ul><ul><li>A subfield of computer graphics and animation. </li></ul><ul><li>Created by means of 3D computer graphics, though 2D computer graphics are still widely used for stylistic, low bandwidth, and faster real-time rendering needs. </li></ul>
  5. 5. Computer Generated Imagery/ Computer Generated Imaging <ul><li>The target can be the computer itself or another medium, such as film. </li></ul>
  6. 6. Computer Animation <ul><li>A digital successor to the art of stop motion animation of 3D models and frame-by-frame animation of 2D illustrations. </li></ul>
  7. 7. 3D Animations <ul><li>Objects (models) are built on the computer monitor (modeled) and 3D figures are rigged with a virtual skeleton. </li></ul>
  8. 8. Tweening or Morphing <ul><li>A process wherein the differences between key frames are automatically calculated by the computer. </li></ul><ul><li>Then the animation is rendered . </li></ul>
  9. 9. 2D Figure Animations <ul><li>Separated objects (illustrations) and separate transparent layers are used, with or without a virtual skeleton. </li></ul><ul><li>The limbs, eyes, mouth, clothes, etc. of the figure are moved by the animator on key frames . </li></ul>
  10. 10. Animation on the Internet <ul><li>Animated text </li></ul><ul><li>Animated GIF’s </li></ul><ul><li>Macromedia Director applications </li></ul><ul><li>3-D environments </li></ul>
  11. 11. 3D Animations 2D Animations All frames must be rendered after modeling is complete Rendering process is the key frame illustration process while tweened frames are rendered as needed.
  12. 12. Prerecorded Presentations <ul><li>Rendered frames are transferred to a different format or medium, such as film or digital video. </li></ul><ul><li>frames may also be rendered in real time as they are presented to the end-user audience. </li></ul><ul><li>Low bandwidth animations transmitted via the internet – 2D Flash, X3D – often use software on the end-users computer to render in real time as an alternative to streaming or pre-loaded high bandwidth animations. </li></ul>
  13. 13. 2-D Animation <ul><li>Two types of animation exist: </li></ul><ul><li>Cel animation </li></ul><ul><ul><li>Based on changes that occur from one frame to the next. </li></ul></ul><ul><li>Path animation </li></ul><ul><li>Moves an object along a predetermined path of the screen </li></ul>
  14. 14. Three Steps of 3-D Animation: <ul><li>Modeling – creating the broad contours and structure of 3-D objects and scenes </li></ul><ul><li>Animation – defining the object’s motion </li></ul><ul><li>Rendering – giving objects attributes such as color, surface textures, and amounts of trasparency. </li></ul>
  15. 15. 3-D Animation Special Effects: <ul><li>Morphing – blending together two images into a series of images </li></ul><ul><li>Warping – distorts a single image </li></ul><ul><li>Virtual Reality – creates an environment that surrounds the user so that s/he becomes part of the experience. </li></ul>
