  1. Virtual Reality Systems CPSC 411/611Course IntroductionAugust 22, 2012

  2. Welcome! • My name is Dr. Sab Babu • A bit about myself • http://people.clemson.edu/~sbabu • Background • Interests

  3. The Name game • Pair up with someone you haven’t met before. • Find: • Name • Class Standing • Where were you before you came to CU? • Something interesting about them • Take 5 mins, and you will take turns to introduce them in class

  4. Course Run-icity • Ask questions, participation is required!!! • Cheating will not be tolerated. You cheat == no longer in class. • Attendance is mandatory • Very APPLIED (lots of projects). You will work hard. • Go over course syllabus in a minute

  5. What’s this course about? • What is a Virtual Environment? • Computer generated environments • Virtual Reality • Augmented Reality • Immersive Environments • Mixed Reality • Learn what goes into VEs • Learn to make VEs • Building your own VE • What are the research areas in VEs?

  6. What will we get to do? • Explore a new area of computer science research • Q: How old is VR and who is the ‘father’ of VR? • A: 1965, Ivan Sutherland (The Ultimate Display, first reading) • What is unique about the picture? • What does having the head device get you? • Build your own environments • Build your own interfaces • Develop a significant group final project • Do things that have never been done before!

  7. Course Outline • Build Basic VR walkthrough • Build Basic AR • Background and history of VR • Software • Hardware • Design • Interaction (Wiiii!) • Research Issues

  8. OpenSceneGraph • Open Source Library with a Scene Graph • Rendering, Animation, Object hierarchy • Creating a Joystick enabled virtual walkthrough

  9. AR ToolKit/osgART • Open Source library • University of Washington HITLAB • You will building a AR environments with ARToolKit

  10. Pre-Requisites • Proficient in programming (C/C++) • Programming must not be an obstacle • Must be familiar with Microsoft Visual Studio 2008/2010 • General technical background • Algorithms and Data Structures • Familiar with computer graphics is a plus. However, you can still take this course without a lot of graphics knowledge.

  11. Pre-Requisites • Please drop on by if you have any questions/concerns • You will have to invest in some tools of the trade • Joysticks/gamepad • Earphones, microphone, etc. • No Slackers allowed… • those in search of an easy ‘A’ drop now! • those in search of a rewarding challenge stick around!

  12. Why should I take this course? • An excuse to build that VR program/game/3D project you always wanted • A Computer Science course that involves a variety of skills (other than coding!) • Art • Psychology • Sound • Creativity • To play with fun toys • To show off your projects! • End of the semester final projects (potential advisors!)

  13. Syllabus • http://people.clemson.edu/~sbabu/VEcourse2011.html

  14. Discussion Topic • Let’s design the ultimate VR system. • What are the issues to consider? • Which senses do we want to provide sensory input to? • How would you engineer this? • How much would it cost? • What is possible today, what needs to be invented? • What is the best virtual reality experience available today?

  15. Readings • Chapter 1 – Introduction • "The Ultimate Display," Sutherland, I.E., Proceedings of IFIPS Congress 1965, New York, New York, May 1965, Vol. 2, pp. 506-508. • "A Head-Mounted Three-Dimensional Display," Sutherland, I.E., AFIPS Conference Proceedings, Vol. 33, Part I, 1968, pp. 757-764. • http://www.artmuseum.net/w2vr/timeline/Sutherland.html#SutherlandText

  16. Background Survey: • Name: • Class standing: • What aspect of project development are you most interested in? (System development, 3D modeling, 3D UI development) • What are your strengths? (Familiarity with open source graphics/VE frameworks, modeling tools, etc.) • What would you like to learn? (Opportunity to learn modeling, system programming, UI design etc…) • Briefly describe any current VR project your are working on? • Or, Why you are interested in VR?
