INTRODUCTION
"It is not just that such images [CGIs] raise the
   stakes of what can be represented, but that
   they are ... more real than the real ... "

         Why did we chose this topic?
                 •  Common interest.
             •   Relevant to our course.
             •   Explore various aspects.

CGI IN SCI-FI:
FROM STAR WARS TO
  THE AVENGERS
THE EARLY DAYS
• CGI & Science fiction go hand in hand.
• 3D CGI first used in 'Futureworld' (1976)


                      ‘Star Wars: A New Hope’ (1977)
                        used 3D wire frame graphics.




• 1982 – ‘Tron’ - first
  movie to have extensive use
  of solid 3D CGI.
  Very little processing
  required.
RISE IN POPULARITY
• Sci-Fi movies become more prominent and successful through
  the use of CGI.

• CGI has helped make certain elements cheaper to create.

• Younger audiences in a video game culture.

• End of 20th century - New advances in CGI
  - 'The Matrix' (1999) - Bullet Time.

• Increase in big budget, CGI
  inspired, sci-fi movies.
•    'The Lord of the Rings' Trilogy (2001-2003) blended live
     action and CGI seamlessly.
•    AI used for digital actors
    - Eg. Gollum




                   'Avatar' (2009) - first full length movie to use
                   performance capture to create photorealistic
                   characters and environments.


•   'Avengers Assemble' (2012) - Used CGI throughout to make
    unrealistic characters and creatures look exactly like reality.
Realistic CGI &
 Animation
Realistic CGI & Animation
•   Character - Body Movements
•   Personality - Facial Expressiveness
•   Polygon Meshes - Fast rendering, common,
    lots needed.
•   Human Face - Bossels and Depressions,
    shading problems, motion and close-up
    detail.

•   Empathy, Agency (impacting an event)
•   No sudden movement
Methods
                  Realistic CGI
• Photographs
• Cross sections - topographic map, contours
• Magnetic-field 3D digitizing - faster
• Plaster, sculpting, projected grid
Making it easier
• Reusing old assets
• Symmetry
• Computer sculpting - Adding, removing,
  assembling - "Spaceball"
• Spheres, Cylinders, Points, Moulding
vs.
Realistic Animation
•   Actions follow screenplay and storyboard
•   Motion capture - expressiveness
•   Suite of emotions/motions
•   Not producing a generalization, but working
    off a blank slate.
•   Reusing animation assets
•   Colour, texture eg. blushing
•   Intermediate emotions can
    be generated by computers.
Cartoon Animation
Cell Animation
•   Traditional method of animation
•   Each image is drawn by hand
•   Main method until computer animation


             Method:
•   Artists drew on
    transparent pages ("cells")
•   Coloured in by hand
•   Sections could be moved
     without redrawing entirety
CAPS
•   "Computer Animation Production System"
•   Developed by The Walt Disney Company and Pixar in
    the late 1980's
•   The first computer paint system
•   Image outlines were scanned onto computers, then
    painted
•   Enclosed blocks of images could be painted with a
    mouse click
•   Improved colour blending, shading, camera movements
•   The Rescuers Down Under (1990) was the first film
    entirely made using CAPS
•   Images were 2D looking and CAPS stopped being
    popular in 2004
3D CGI Animation
•   Even outline drawings are drawn on the
    computer, not by hand
•   Small components can be
    modified, not just layers
•   Improves perspective and
    makes the image look 3D
•   Cel shading: "toon shading" used to make
    computer images appear hand drawn. Gives
    a more "traditional" feel
Conclusions
•   From doing this presentation we have learned that tricks
    of the trade are used across specialities.


•   Computer Generated Images in movies are improving
    at a fast rate. The detail in graphics available now were
    not even dreamt of years ago.


•   The things we have learned can help us in the future
    with projects and in the workplace.
