There is no particular mystery in animationits
really very simple, and like anything that is
simple, it is about the hardest thing in the
world to do. --Bill Tytla at the Walt Disney
Studio, June 28, 1937

Computer Animation

• Creating moving images through the use of
  computers
• Can be done using both computer graphics and
  animation.
• It is created by 3D computer graphics

Computer Graphics

• Computer graphics is digitally synthesizing and
  manipulating the visual content that one has.
• This often refers to 3D computer graphics but
  also includes two dimensional graphics and image
  processing.

5
Animation

• Animation can be produced in two ways
• Create a succession of cartoon frames, which are
  combined into a film
• Use physical models, which are positioned and
  then filmed

6
3D Computer Graphics

• Graphics that utilize a 3D representation of
  geometric data that is stored in the computer

Pixars Short Animated Films

• The computer animated industry started with short
  films.
• John Lasseter created the studios first short
  film Luxo, Jr. which is about a desk lamp and its
  child.
• This led to another animated film, which won an
  academy award called Tin Toy.
• Tin Toy led to the creation of Toy Story.

Toy Story

  Walt Disney of animation.

The Making of Toy Story

• Sculpture
• Gave an idea of what the character would look
  like and also a glimpse of what scale,
  complexity, movements, and expressions would be
  needed.
• Visualization
• Voices of Tom Hanks and Tim Allen were done first
  to visualize the faces and reactions of what the
  characters would look like.

The Making (Cont.)

• Animation
• RenderMan
• Allowed the visual effects artists to handle very
  large renderings at ease.
• Lines of Code
• Woody-52,865 lines of code, 712 different
  animation controls, and 212 in his face, 26
  texture maps
• Buzz-189 texture maps
• There were 25,000 storyboards and each and every
  move by the characters had to be animated

11
Finally

• Rendering took a total of 800,000 hours together.
• The sounds, graphics and more took 2 terabytes
  which is 2 trillion bytes of space.
• Made a 79 minute movie that was the first film to
  be entirely rendered by computer.
