A basic look into what is CGI, it's need in today's time, it's history and future scope.

1. COMPUTER GENERATED iMAGERY Pribhat singh sharma

2. Introduction What is CGI? Need for CGI. History of CGI. Applications of CGI.

3. History of CGI… A look into past…

4. From the Beginning… 1928 Hollerith introduces the 80-column “punch card” 1939 Bill Hewlett and Dave Packard design the Audio Oscillator 1200 Chinese Abacus 1617 Napier’s Bones

5. 1950 - 1970 1950s 1956 Alex Poniatoff ( Ampex ) introduces the VR1000 videotape recorder (2"tape) - the first practical broadcast quality VTR  . 1960s 1960 William Fetter of Boeing coins the term "computer graphics" for his human factors cockpit drawings 1970s 1977 Larry Cuba produces Death Star simulation for  Star Wars  using GRASS ( GRAphics Symbiosis System ) at UICC.

6. 1960 - 2000 1980s 1982 Skeleton Animation System (SAS) developed at CGRG at Ohio State (Dave Zeltzer ) 1990s 1997 IBM Deep Blue wins at chess 2000s 2000 PlayStation 2 Dinosaur produced by Disney

7. Components in CGI

8. Fractals “A fractal is a mathematical set that typically displays self-similar patterns.” Generation Techniques : Iterated F unction Systems Strange Attractors Escape-time fractal Fractal Flame

9. Fractal Landscape

10. Fractal Terrain Fractal Pasture

11. Architectural Scenes Visualize Space Perform Walk-throughs Interactive Environments Applications: Specification of building structures Walk-Throughs Effects of Light

12. Anatomical Models Computer generated models. SCII developed anatomically correct models. Used for instructional and operational purposes.

13. Cloth Imagery Models of  cloth : Geometric-Mechanical structure at yarn  crossings. Mechanics of continuous elastic sheets. Geometric Macroscopic features of cloth .

14. Skin Imagery Human skin  images:  Photo Realism . Physical Realism. Functional Realism

15. Computer Animation “Computer animation or CGI animation is the process used for generating   animated images   by using   computer graphics ”

16. Computer Animation Computer Animation  only refers to moving images. Modern Animation – 3D & 2D computer graphics. Digital successor to Stop Motion Techniques. How is Computer Animation achieved? Tweening – Morphing – Rendering.

17. 1993 – The Nightmare before Christmas. 2009 – The Fantastic Mr. Fox 2009 - Coraline 2005 - Wallace & Gromit : The Curse of the Were-Rabbit Feature films which used Stop Motion Technique

18. Tweening – Example of a tween. Morphing – George Bush to Arnold S.

19. Rendering

20. Applications Medical Imaging. Visible Human Project. Zygote Body. Living Human Project. Realism in computer animation. Video Games. Feature Films. Computer-Aided Design for engineering and architectural systems. Presentation Graphics. Computer Art.

21. Applications Medical Imaging Zygote Body

22. Visible Human Project

23. Sideview Frontview

24. Animated Feature Films

25. Applications Animated Models in games Realism in games

26. Future of CGI… What does the future has in store for cgi …?

27. Future of CGI Realism. Virtual Reality. Examples.
