VRML Introduction 

What Is VRML?

VRML, sometimes pronounced "vermal," is an acronym for the Virtual Reality Modeling Language. VRML provides a bare minimum of geometric modeling features and contains numerous features. VRML is a 3D analog to HTML. This means that VRML serves as a simple, multiplatform language for publishing 3D Web pages. This is motivated by the fact that some information is best experienced three dimensionally, such as games, engineering and scientific visualizations, educational experiences, and architecture. Typically these types of projects require intensive interaction, animation, and user participation and exploration beyond what is capable with a page-, text-, or image-based format (i.e., HTML). VRML provides the technology that integrates three dimensions, two dimensions, text, and multimedia into a coherent model.

How do I navigate the VRML world?

This site uses a VRML browser called Cortona VRML Client. 

Cortona runs inside Netscape or Internet Explorer. 

When a page is loaded with VRML, Cortona loads itself inside 

your internet browser.

You use the main controls on the Cortona dashboard to:

• move around in 3D worlds
  • zoom in/out-PLAN
  • PAN left/right/up/down
  • TURN or ROLL objects around
  • GOTO certain points on objects
  • ALIGN object with viewport
• examine objects in 3D worlds
• click on objects to display information
• change controls from study(used for this site), fly, or walk
• change viewpoint points VIEW
• change transparency on certain objects
• restore objects original position
• fit all objects in viewport

Clicking in designated areas will bring up 3D models

How do I know what I am looking at?

When the mouse rolls over an object, the object's name is displayed in the bottom panel of your web browser. Clicking on an object will display information in the bottom text window.

When I click on an object the correct text doesn't appear

Sometimes other objects block the object you desire. Transparent objects can be tricky when they block the view of another object. When this happens just rotate around the object and click in a different viewing location.

When I move around I get disoriented

If you get disoriented or lose your position, click the RESTORE button at the bottom right hand side.  This option will restore the view to the original position.
