7. Components in CGI

8. Fractals
 “A fractal is a mathematical set
that typically displays self-similar
patterns.”
 Generation Techniques :
 Iterated Function 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:
i. Geometric-Mechanical
structure at yarn crossings.
ii. Mechanics of continuous
elastic sheets.
iii. Geometric Macroscopic
features of cloth.

14. Skin Imagery
► Human skin images:
i. Photo Realism.
ii. Physical Realism.
iii. 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
