VRML MODELS ~ virtual
reality       
 


Have fun with VRML. Walk around the Jaipur sundial observatory. This is an exciting and
under used feature of the web. I have used ISB for all the virtual worlds, ISB is from Parallel
Graphics, who have a
repository of worlds here. And here is the required plug in.
TurboCAD
Deluxe (has full 2d and 3d modeling)  
their main web page is
here
deluxe is inexpensive, professional is costly
                               but supports scripting
                                    
vrml models (require the Cortona plugin,
see here)      
Armillary   Equatorial    etc - see the vrml pages                              
My main TurboCAD files page (free)
includes macros and programming notes
(TurboCAD VBS sdk stuff)
MAIN vrml page - full worlds (built with ISB and
ISA) and separate sundial models built with
TurboCAD saved as vrml 2 - some linked to in the
worlds also
MAIN VIRTUAL REALITY PAGE (free)
Scilab, Euler, and Octave
( free, has a scripting language, while not really a CAD
system, they each have amazing programming abilities.)
My Scilab files page (free)
My Euler files page (free)
My Octave files page (free)
DeltaCAD
(is 2d only, but has a scripting language)
their main web page is
here
is inexpensive  
My main DeltaCAD files page (free)
includes macros and programming notes
animated dials, almanacs, and many dial types
NASS DeltaCAD page
PowerDraw
is free, has a Pascal like macro facility
needs SIN, COS, TAN ASIN, ACOS, ATAN
and SQRT assist
which I have in my macros
My Powerdraw page (free)
includes program and notes
FREE CAD OR VRML STUFF
ProgeCAD
(is free, has the LISP scripting language)
their main web page is
here
My LISP files page (free)
includes program and notes
NanoCADCAD
is free, has the VBS and Java Scripting
My VBS & JS files page (free)
includes program and notes
FreeCAD
is free, has Python scripting
My Python files page (free)
includes program and notes
My virtual reality (VRML) page
VRML plugin from Cortona (use the 32 bit version)
Virtual Reality Jaipur Observatory
A VIRTUAL "YOU WALK AROUND" TOUR OF JAIPUR SUNDIAL OBSERVATORY ~ AND OTHER USER MANIPULATABLE DIAL THINGS.   It needs the certified
VRML plugin
from Cortona which is very easy to install, and uses Active-X when a vrml figure is invoked.   It takes 10 to 20 seconds to load a VRML object in
ActiveX so do not panic if it takes a bit of time.
