  1. 1. COMPUTER ANIMATION BY, B.SHUSRUSHA III YEAR IT-B.
  2. 2. LET USENTER INTO THE MAGICAL WORLD OF ANIMATION
  3. 3. • INTRODUCTION • APPLICATIONS • DESIGN OF ANIMATION SEQUENCES • GENERAL COMPUTER ANIMATION FUNCTIONS • RASTER ANIMATIONS • COMPUTER ANIMATION LANGUAGES • KEY FRAME SYSTEMS • MOTION SPECIFICATIONS
  4. 4. • Computer animation is the process used for generating animated images (moving images) using computer graphics. • Animators are artists who specialize in the creation of animation. • From Latin animātiō, "the act of bringing to life"; from animō ("to animate" or "give life to") and -ātiō ("the act of"). INTRODUCTION 2D ANIMATION 3D ANIMATION
  5. 5. APPLICATIONS Video games cartoon Mobile phones
  6. 6. DESIGN OF ANIMATION SEQUENCES • Steps for designing animation sequences. 1.Storyboard Layout 2.Object definitions 3.Key frame specifications 4.Generation of in-between frames
  7. 7. Storyboard Layout
  8. 8. Object Definitions
  9. 9. Key frame Specifications
  10. 10. In-between frames
  11. 11. GENERAL COMPUTER ANIMATION FUNCTIONS Amorphium Art of illusion • Animation software provide basic functions to create animation and process the individual object. FUNCTIONS Manipulate data object database. Motion generation. Object rendering.
  12. 12. Raster Animations •Real-time animations can be generated using raster operations.
  13. 13. ORGANISATION OF A VIDEO COLOUR TABLE 0 1 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 255 65 0 41H 65 Red Green Blue Monitor Pixel value 24-bit
  14. 14. Computer Animation Languages • GENERAL PURPOSE LANGUAGES:C,C++,Pascal, or Lisp(control animation sequences).
  15. 15. SPECIALIZED ANIMATION LANGUAGES • Key frame systems • Parameterized systems • Scripting systems
  16. 16. Key frame Systems
  17. 17. Motion Specifications •Various ways in which motions of objects ca be specified as: •Direct Motion Specification. •Goal-Directed Systems. •Kinematics and Dynamics.
  18. 18. Direct Motion Specification
  19. 19. Goal Directed System
  20. 20. Kinematics and Dynamics • KINEMATICS: • Motion parameters such as position , velocity and acceleration are specified without reference to the forces. • INVERSE KINEMATICS: • Initial and final positions of objects at specified times and from that motion parameters . • DYNAMICS: • The forces that produce the velocities and accelerations are specified(physically based modeling). • It uses laws such as Newton’s laws of motion , Euler or Navier -stokes equations.
