ITIS 1210Introduction to Web-Based Information Systems Chapter 40 How Virtual Reality Works
Introduction • Advantage of the Internet • Brings computing power into your home • Examples • Word processing • Spreadsheets • Databases • Programming • Makes specialty applications available to the masses
Introduction • Virtual Reality • “Like” reality (only different) • Enables simulations of reality • Not as good as … • But WAY better than what was available before • Many virtual worlds you can explore on the Internet
VRML • Created using a Virtual Reality Modeling Language (VRML) • Used to build 3-D objects • Describes geometry of the scene • VRML • Creates as ASCII text file (.wrl) • Perhaps some graphics files also • Easily (quickly) downloaded to your PC
VRML • Posted to an Internet Server • You enter URL • May need a plug-in • VRML file downloaded • Depending on size may take a while
VRML • VR plug-in launched • Takes over control of browser • Using VRML data, • Your computer creates the virtual world • VRML contains 3D information • You can navigate around in virtual world • “Fly”, walk, run, etc.
VRML • Objects in virtual world can be links to • Sites • Animations • Other virtual worlds • May require another download & set up • Virtual world doesn’t have to be completely constructed • Graphics can be “painted” on objects
VRML • Examples • http://www.bostonvirtualimaging.com/gallery-virtual-tours.html • http://www.seeinsidemyhome.com/1234VeroBeach/1234.html • http://www.quantumvr.com/usstour.html
