Virtual Reality page    

The vrml worlds use the Cortona browser plug-in, which supports vrml animation, and you can wander around the worlds.
Most of these vrml worlds link to each other, but in case you have difficulty, separate urls are listed below.

STUFF ABOUT BUILDING VIRTUAL WORLDS

These worlds can be browsed with any VRML browser, i.e. Mozilla, Netscape, and Internet Explorer with the Cortona vrml plugin,
Browsing online works, but double clicking a saved vrml file on disk does not. The standalone vrml viewers below work on Vista win64
however while they support vrml models, they do not support vrml worlds such as Jaipur:-

On
Windows Vista win64, using the Cortona plugin, may sometimes crash. Mostly it works. It does work with my Jaipur world of
sundials, and it also works for my individual dials. BUT for standalone viewing offline, and not all models work so persevere, use a
standalone viewer such as:-

These worlds were created with the ISB product from
Parallel Graphics using the PUBLISH function. These worlds are also on the CD
that goes with the book.  The animation was added after the basic worlds were created using ISA from Parallel Graphics also, and
they use the PUBLISH function, and also require the SAVE function. The ISB and ISA programs have trial download versions. Use ISB
to first build the main world, and to establish viewports, and only when happy with it, then and only then use ISA to animate it.
The ISB
builder user may wish this
BASIC program to cross check urls of a published .wrl world, written using Just BASIC which is free here.
Other vrml files are here as links on the main web page.
VIRTUAL REALITY WORLDS OF SUNDIALS ~ you can walk around them.

VRML and later X3D is to 3d virtual reality what HTTP is to text and simple graphics. With VRML you may maneuver around 3d objects. Illustrating
Shadows brings virtual reality to both web users as well as to stand alone computers when it comes to sundials.

Web browsers (Netscape, Mozilla, Internet Explorer) do not support VRML or X3D directly, they need a plugin. There are many plugins, for XP and
Vista win64 the Cortona plug-in is fully usable.
BOTTOM LINE:  for internet stored worlds, use the Cortona Plugin.

File browsers for large virtual worlds: if the virtual worlds are on your computer and not on the internet, then you may use Instant Player on
Windows Vista, or you may use Internet  Explorer with the Cortona plugin if you are using Windows XP.
BOTTOM LINE: for worlds stored on your computer
use INSTANT PLAYER for late XP serivce packs or Vista, and Cortona for early XP systems. NOTE: If you get file associations right, Cortona enabled,
and answer YES to all sorts of ActiveX messages, the Internet Explorer+Cortona works on Vista, if any problems then use Instant Player.

File Browsers for small sundial models: the Cortona Browser plugin works if internet based, for computer based it also works for old XP
systems. For later XP systems or Vista use  SWIRL.
NOTE: If you get file associations right, Cortona enabled, and answer YES to all sorts of ActiveX
messages, the Internet Explorer+Cortona works on Vista, if any problems then use Instant Player.

CAUTIONS:     Using a web browser with a plugin for computer (as opposed to internet) files may get you into a circle of the computer asking
       permission to open the vrml (.wrl and .wrz) file which never ends, so, use INSTANT PLAYER instead.
       Cortona may crash your Vista win64 computer once or twice, however persevere and it will work very well.

Useful links:     
cic.nist.gov/vrml/vbdetect.html            a useful set of links for misc operating systems and computers
       
www.cortona3d.com/cortona               the plugin for most browsers, for internet based worlds and models.
       
www.instantreality.org                          INSTANT PLAYER works standalone and lets Windows Vista users view computer
                                                                   stored worlds in vrml which is helpful since Vista and later XP service packs prohibit
                                                                   a web browser with a plugin from viewing local files which they allow if from the
                                                                   internet. For small computer based models use SWIRL.
       
www.pinecoast.com                            SWIRL is a good viewer for small models stored on the computer (for worlds use
                                                                   INSTANT PLAYER)

WINDOWS:      Browser plugin:  Cortona                      Navigation uses the mouse and SHIFT or CTRL speeds it up. Hyperlinks to other worlds
                                                                   may or may not work depending on how Windows feels that day. Works for large worlds
                                                                   and small models if internet based, and for computer based files if an earlier XP
                                                                   system. If later XP or Vista and computer based then use INSTANT PLAYER for
                                                                   large worlds such as Jaipur, or Swirl for small models.
       Standalone browser
Instant Player       Works for full scale worlds stored on your computer, worlds such as Jaipur Observatory,
                                                                   not as good for small models.
       Standalone
small model viewer          The Swirl Viewer from Pine Coast works very well for small models of sundials, not
                                                                   usable on large worlds.   
       Another standalone viewer                   An alternative to Pine Coast's Swirl viewer.

INSTANT PLAYER and SWIRL are all free, as is CORTONA.  

Navigation using Instant Reality is best done with NAVIGATE and FLY then use the mouse or arrow, and to speed it up do +++++, and if you hit an object
you must back up.

THE FINE PRINT STUFF ~ IF YOU HAVE TROUBLE READ THIS

Internet Explorer MAY block the VRML as a pop-up, let it proceed.  Consider  the TOOLS, INTERNET OPTIONS, ADVANCED,
ACTIVE CONTENT feature in IE.

Internet Explorer may need you to tell it to
check the cache versus the web site. Consider TOOLS, INTERNET OPTIONS,
GENERAL, TEMPORARY INTERNET SETTINGS, EVERY VISIT TO THE PAGE or AUTOMATIC.

CORTONA FIT helps if the vrml model seems tiny, but only with models, avoid using it on full worlds..  STUDY lets you
manipulate the object Mouse and arrow keys allow navigation.  RIGHT CLICK brings up options, including other viewports.

In CORTONA, SHIFT key speeds movement. Right click get good things, especially viewports. In INSTANT PLAYER use the + or
- numeric pad key to control navigation speed.

The main world is
simon.wrl,  it links to simonHA (hour angle dials), simonJAIPUR, and other  worlds, and those worlds have
links back to the main world. Some have links to detailed vrml dial models you can manipulate. These web urls ARE CASE
SENSITIVE. Some models are not in the link, so separate urls are available below.

Models you can manipulate and study

Windows XP service pack 1 or 2 - Cortona plugin works if using the internet link to my Jaipur world, or, if on
the CD you get with Illustrating Shadows.

Windows Vista and late model Windows XP -
Cortona plugin works if using the internet link to my Jaipur
world, but, if using files on the CD you get with Illustrating Shadows do not use the internet browser, use
Instant Player. Cortona may crash the first time or two, so reboot and persevere, the experience is well worth it.

Here are a few models
The Durer model
Four armillarys
The ecliptic
ANIMATIONS:  The main world has the moon, earth, and sun in orbit, and
the sun orbiting the earth at the solstices and equinox. Jaipur has an earth,
moon, sun orbit system. The sundial garden has the moon, earth, and sun
in orbit, and polaris together with cassiopeia and ursa minor rotating.
Above are a few hot links, the worlds link to many vr models you can
explore, walk around or manipulate and see how they are made.
N and S faces of vertical decliner in vrml 3d  
Jaipur and other full worlds you can walk around this world, click on dials to explore them, and so on.

Windows XP service pack 1 or 2 -
Cortona plugin works if using the internet link to my Jaipur world, or, if on
the CD you get with Illustrating Shadows.

Windows Vista and late model Windows XP -
Cortona plugin works if using the internet link to my Jaipur
world,
but, if using files on the CD you get with Illustrating Shadows, use Instant Player. Cortona may crash
the first time or two, so reboot and persevere, the experience is well worth it.

There are other worlds also, such as
"*" means animation in the model
The entire solar system is about 2mb
so don't even think of using dial up
entire solar system *
Earth, moon, sun *
A sundial garden *
Main world *
Jaipur observatory *
A house and the dials
