Presentation Transcript

  1. ICS 415Computer Graphics Introduction Dr. Muhammed Al-Mulhem March 1, 2009 Dr. Muhammed Al-Mulhem

  2. Topics • Graphics Concepts • Modeling transformation, viewing transformation, hidden surface removal, illumination / shading / textures, scan conversion / clipping • OpenGL • Morphing, curves and surfaces, animation • Not a course about graphic design, using graphics tools like PhotoShop or Maya Dr. Muhammed Al-Mulhem

  3. Assignment - Honor Code • When in doubt… • Don’t use resources other than class notes and textbook • Typically… • Using examples from the web is a great way to learn and it is encouraged… reference what you use • Never • Share code with another student or debug code together Dr. Muhammed Al-Mulhem

  4. Impact of Computers • Moore’s Law • Power of a CPU doubles every 18 months / 2 years Dr. Muhammed Al-Mulhem

  5. Lee Majors Impact of Video Games (Nvidia) • Number of transistors on GPU doubles each 6 mos. • Three times Moore’s Law • Good article on Jen-Hsun Huang, Nvidia CEO: http://www.wired.com/wired/archive/10.07/Nvidia_pr.html Worldwide revenues $5.6 Billion Man $7 Billion Man Dr. Muhammed Al-Mulhem

  6. Future of Consoles • 33 million PS2s (in 2002) • 3.9 million Xboxes (in 2002) • Predicted 200 million PDA/Cell game players in 2005 Dr. Muhammed Al-Mulhem

  7. Graphics Applications • Entertainment: Cinema Pixar: Monster’s Inc. Square: Final Fantasy Dr. Muhammed Al-Mulhem

  8. Entertainment Final Fantasy (Square, USA) Dr. Muhammed Al-Mulhem

  9. Entertainment A Bug’s Life (Pixar) Dr. Muhammed Al-Mulhem

  10. Graphics Applications • Medical Visualization The Visible Human Project MIT: Image-Guided Surgery Project Dr. Muhammed Al-Mulhem

  11. Graphics Applications • Everyday Use • OS use graphics seriously • Graphics visualizations and debuggers • Visualize complex software systems Dr. Muhammed Al-Mulhem

  12. Everyday use Dr. Muhammed Al-Mulhem

  13. Everyday use Window system and large-screen interaction metaphors (François Guimbretière) Dr. Muhammed Al-Mulhem

  14. Graphics Applications • Scientific Visualization Dr. Muhammed Al-Mulhem

  15. Scientific Visualization Airflow around a Harrier Jet (NASA Ames) Dr. Muhammed Al-Mulhem

  16. Graphics Applications • Computer Aided Design (CAD) Dr. Muhammed Al-Mulhem

  17. Graphics Applications • Training Designing Effective Step-By-Step Assembly Instructions (Maneesh Agrawala et. al) Dr. Muhammed Al-Mulhem

  19. Games Circus Atari (Atari) Dr. Muhammed Al-Mulhem

  20. Education Outside In (Geometry Center, University of Minnesota) Dr. Muhammed Al-Mulhem

  21. The Basics • Computer graphics: generating 2D images of a 3D world represented in a computer. • Main tasks: • modeling: (shape) creating and representing the geometry of objects in the 3D world • rendering: (light, perspective) generating 2D images of the objects • animation: (movement) describing how objects change in time Dr. Muhammed Al-Mulhem

  22. Why Study Computer Graphics? • Graphics is cool • I like to see what I’m doing • I like to show people what I’m doing • Graphics is interesting • Involves simulation, AI,algorithms, architecture… • I’ll never get an Oscar for my acting • But maybe I’ll get one for my CG special effects • Graphics is fun Dr. Muhammed Al-Mulhem
