  4. 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

  5. VRML • Posted to an Internet Server • You enter URL • May need a plug-in • VRML file downloaded • Depending on size may take a while

  6. 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.

  7. 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
