  INTRODUCTION  Computer Animationis the process used for generating animated images using computer graphics.  Animators are artists who specialize in the creation of animation.  From Latin amatio, “the act of bringing to life”; from animo(”to animate” or ”give life to ”) and –atio (“the act of”). 2D Animation 3D Animation 3

  STORYBOARD LAYOUT  Itis the outline of a action. It defines the motion sequences as a set of basic that are to take place.  Depending on the type of animation to be produced, the storyboard could be consist of a set of rough sketches or it could be a list of basis ideas for motion. 6

  OBJECT DEFINITIONS  Eachobject participating in the action is given object definition, such as terms of basic shapes, such as polygons or splines. 8

  FRAMES  It isone of the many single photographic images in a motion picture. The individual frames are separated by frame lines. Normally, are needed for one second of flim. 10

  KEY FRAME  Akey frame in animation and filmmaking is a drawing that defines the starting and ending points of any smooth transition.  A sequence of key frames which movement the spectator will see, but the position of the key frames on the film, defines the timing of the movement. 2 or 3 can be present for a span of a second. 12

  IN BETWEEN  Itis a process of generating intermediate frames between 2 images to give appearance that the 1st image evolves smoothly into the second image. In-betweens are the drawing between the key frames which help to create the illusion of motion.  Film requires 24 frames per second and graphics terminals are refreshed at a rate of 30 to 60 frames per second. 14

  RASTER ANIMATION  Onraster systems, we generate real-time animation in limited application using raster operation.  Such as 2D or 3D transformations on objects.  We can also animate objects along 2D motion paths using the color table transformation. 16

  GENERAL COMPUTER ANIMATION FUNCTIONS AnimationPackages, such as wave font, provide special functions for designing the animation and processing individual objects.  Object manipulation and rendering  Camera motions  Generation of in-betweens 17
