VRML Worlds (Please note that all of the sites listed below are external sites and may contain bad or missing links):
 

1. http://www.avatara.com/vrml/  This site has many different worlds that show places that exist in real life, such as Stonehenge in England and the Sphinx in Egypt.  This is a great tool to use when showing students what other places in the world are like.  The geometry used in many of these places corresponds to the real dimensions of many of the buildings, showing the use of geometry and mathematics in the real world.
    
2. http://www.atom.co.jp/vrml2/  This website contains mostly games that are not unlike video games that many students play.  This a great site to use to begin learning how to navigate around VRML programs.  Trying to win the game provides motivation to become familiar with VRML tools.
    
3. http://www.parnasse.com/vrml.shtml  Some of the programs on this website deal with harmonics and sounds.  One such program distorts the sounds in different ways by echoing the sound in a bowl-shaped object.  Another program produces ecstatic harmonies that have been derived from the harmonic sequence.
    
4. http://www.georgehart.com/virtual-polyhedra/vp.html  This site has plethora of geometric objects that can be viewed and examined in three-dimensional space.  They range from a wide variety of simple objects like cubes and pyramids to complicated figures like a great icosihemidodecahedron and rhombic dodecahedrons with different stellations.
    
5. http://vrmlworks.crispen.org/worlds.html  This site has a large amount of hyperlinks to different worlds.  There are several different topics that one can choose from to see VRML used in many different contexts.  There are different topics under subheadings such as the sciences, the arts, places, and other various subheadings.  This collection can be used to demonstrate the diverse assortment of uses for VRML.
    
6. http://www.planet9.com/demos.html  This site is intriguing as it uses VRML to demonstrate, in three dimensions, different aspects of government security.  It has cities that can be explored through VRML; also, it has media demonstrations that show how the government uses VRML for homeland defense, military uses, and a few more.
    
7. http://www.ocnus.com/models/  This site has a variety of different topics to choose from that displays the different uses of VRML.  This site goes one step further, however, by putting the gallery of topics inside another VRML program.  This second program is called “VRML Mall” and is a gallery of the models.  The models also have hyperlinks if the mall doesn’t load.
    
8. http://www.honeylocust.com/Stars/  This site can be used to demonstrate the galaxy in three-dimensional space.  The VRML programming is used to show the 375 brightest stars in the night sky, displaying their positions in relation to one another.  On the page there are links to two other sites that have “Stars in VRML” and “Galaxies in VRML.”  This site is useful for demonstrating the positional relationships between stars and galaxies in the universe.
    
9. http://evlweb.eecs.uic.edu/pape/vrml/CAVE/  This site has a group of different interactive VRML programs.  It’s a good place to go when first working with VRML to learn the VRML navigational tools.  These programs used to be written in a different language and were translated to VRML, so some of the programs (for example, Crayoland) appear differently than other programs, but they will still help improve understanding of VRML.
    
10. http://www.murdermystery.com/vrml/index.html  This site demonstrates the full capabilities of VRML in a way that is fun and exciting.  It is a “whodunit” game that uses many different aspects of VRML.  It is a great tool to use to familiarize oneself with VRML.
     
11. http://mars.sgi.com/vrml/vrml.html  This site contains a variety of programs that deal with our solar system; more specifically, with the planet Mars.  One program shows the entire layout of our solar system, while another program includes a land rover traveling across the surface of Mars.  There are more VRML models of the Lander site, more rovers, and different space- and Mars-related objects.
     
12. http://www.kahunanui.com/vrml20.html  The different games and models on this site show the use of CGI in a VRML program.  There are different learning games that can fall under the categories of space, ocean, objects, and many others.  The models illustrate the use of different nodes in VRML and what they look like.
     
13. http://www.geocities.com/Paris/6502/  Go to this site and scroll down to the VRML section where there are four simple programs that show different scenes.  Throughout the whole page of this site there are links to different programs for physics, algebra, ecology, and more.  This site has a wide variety of demonstrations of VRML.
     
14. http://www.vrmlworlds.com/  This site has different scenes with links to informative sites that explain the site.  One such example is a model of a NASA launch pad with a hyperlink to www. space.com, where there is a wide variety of NASA and space stories.  There are other programs with varying scenes that can prove to be useful learning tools.
     
15. http://id.mind.net/~zona/VRML/vrml.html  This site is put on by the National Institute of Standards and Technology.  It has a fair amount of scientific, engineering, and mathematical VRML worlds.  There are worlds with matrix plots, different geographical terrains that can be explored, and even a model of an SSN-688 hull and reactor compartment.  There are many more models that deal with engineering.
     
16. http://www.visualizationsoftware.com/3dem/vrml.html  This site contains a number of VRML models that deal with mountainous land-forms.  There are programs that show Mount Saint Helens, Olympus Mons on Mars, the Pacific Ocean Ridge, and quite a few more.  Each model is exactly to scale, and the appearance comes from pictures from sources such as NASA and Landsat.
     
17. http://www4.tpg.com.au/users/gperrett/links.html  This site is one to explore at leisure because it contains a lot of links to different sites with VRML games, random VRML worlds, and avatars.  It’s a great place to go when trying to find a specific program to demonstrate a certain principle with VRML.
     
18. http://www.geom.uiuc.edu/software/weboogl/zoo/  This site has a lot of geometrical figures that can be explored.  There are some objects that are compiled of more than one hundred objects positioned in different places.  These models are great examples of what can be formed from the simple objects that are used in VRML programming.
     
19. http://www.frontiernet.net/~imaging/math_is_a_game.html  This site contains programs that look a lot different from most VRML programs because the programming is combined with Java to form models.  It contains different math tools that can be useful in the classroom, such as a calculator, a vector grapher, and an equation grapher.  There are also many more things that can be used in different education areas.
     
20. http://poncelet.math.nthu.edu.tw/chuan/vrml/vrml.html  This site contains quite a few different models of geometric figures, some of which are interesting to look at and examine once in the program.  At the bottom of the page there is a list of the different names of the objects.  Each name in the  list is a hyperlink to more models of that kind of figure, and some of them have a definition of the shape.
       
21. http://tecfa.unige.ch/vrml/  This site contains a list of several different links to follow.  Each link contains either lists of VRML programs or more links to lists of VRML programs.  Each of the programs is fairly simple but they are of real world objects that can be added into other programs with ease to simplify the program.  There is a wide variety of objects from refrigerators to sailboats, and many more.
     
22. http://www.cybertown.com/vrml20/apta/apta.html  This site is a free example of what is known as “Cybertown” for those on the web.  Cybertown is an online version of real town, with jobs, communities, houses, stores, and much more.  This example is an apartment building within Cybertown.  The furniture is movable, the lights can come on, and a few other things.  Cybertown is an interactive world, complete with 3D chat so the users can communicate with one another.
     
23. http://www.htmlcenter.com/tutorials/tutorials.cfm/97/vrml  This site contains seven VRML programs that can be used in home scenes.  There is a chair, a table, a desk, a tree, a sofa, a bed, and a television.  The programs are simple and the coloring makes them difficult to see, but that can easily be modified when entered into another program.
