Made in TurboCAD, these 3d images were built using the antique stereogram technique. To view, just look in the
middle of the two pictures of the pair you want to see in 3d, and let your eyes drift. Then three pictures will be seen, the
midde one being in 3d. For example, using the 3d mesh below, let the eyes drift until the black hemispheres at the
focus of the mesh on the brick plate both merge together, Then the center of the three pcitures is in 3d. Or if you like,
cuth them out and view them with an old stereo viewer. The book has several such examples. More may be added
here depending on how often this web page is accessed.       

Some of the dials in the book are on the
virtual page of this web site, either asis, or in the virtual worlds. As vrml
objects you can rotate and study them. The Jaipur India virtual world has a virtual world you can walk around, and click
to learn more about the dials there. Also, there is a garden of virtual dials you may walk around and study. Most virtual
worlds on this web site include an animated moon/eart/sun model, as well as a full solar system in animation.

Some of my 3d CAD images first appeared on The
Sundial Primer web site which has a CAD dial section.
