1. CGMB214: Intro. To Computer Graphics Chapter 1 Introduction

2. What You Need to know What is computer graphics? What is our approach?

3. What is Computer Graphics? What? What is it for? Where it is being used? How it is used? Motivation? Why learn CG?

4. What is Computer Graphics? Pictures generated by computer Tools to make pictures Hardware tools – monitor, mouse etc Software tools – OS, debugger, graphics libraries etc Field of study that involves pictures produced and tools used

5. What exactly is Computer Graphics? Pretty Pictures Data Structures AlgorithmMathematics

6. What CG is used for? To produce RAPID and ECONOMICAL PRODUCTION of pictures

7. Where CG is being used? Computer Graphics Art, Entertainment, Publishing Computer Graphics and Image Processing Monitoring a Process Displaying a Simulation Computer Aided Design Scientific Analysis and Visualizations

8. CG in Art, Entertainment, Publishing Movie Production, Animation, Special Effect 2012 LOTR Shrek Harry Potter Computer Games Ragnarok Mario Bro. EA Sport series Browsing the WWW Groovy Slide, Book and Magazine Design Paint Microsoft Publisher Microsoft Power Point Mapmaking

9. CG in CG and Image Processing CG create images IP enhance images Image from camera Image created (CG) Satisfied with Image? Image accepted NO Enhance Image (IP) YES

10. CG in CG and Image Processing CG combines with IP

11. CG in Monitoring Process Usually used in factory, research

12. CG in Displaying a Simulation Virtual Reality – Research – Education – Entertainment

13. CG in Computer Aided Design Computer Aided Architectural Design Electric Circuit Design Benefits of CAD Drives the high-end of the hardware market Integration of computing and display resources Reduced design cycles

14. CG in Scientific Analysis and Visualization Computer graphics makes vast quantities of data accessible. Numerical simulations frequently produce millions of data values. Satellite-based sensors amass data at rates beyond our abilities to interpret them by any other means than visually. Mathematicians use computer graphics to explore abstract and high-dimensional functions and spaces. Physicists can use computer graphics to transcend the limits of scale.

15. How CG is used? Computer Graphics Create ToolsHardware Output Devices Input Devices Graphi c Card Software OSCompilerDebugger Graphic Library Create Libraries Functions/ routines to draw Elaborated – e.g. menus Using APIs – e.g. OpenGL, DirectX, Java3D

16. Motivation for CG Appealing pictures produced Humans respond better to pictorial information Human brain recognizes visual patterns “If it looks right, it is right”, Jim Blinn, CG pioneer

17. Why Learn CG? Better information presentation Job in computer graphics (games, movies, etc) New medium for artistic expression Communicate ideas better Create more user-friendly systems

18. What is Our Approach? learn algorithms use OpenGL as concrete example
