INTRODUCTION
- What is stereo vision?
It is the way we see the world around us. Our 2 eyes give us visual
information from a slightly different angle, the brain combines these two images (the stereopair)
into one image with ‘depth’ in it - we can see the third dimension. The two images can be reproduced with a
stereocamera (which has two lenses at eye distance) or with two computer
generated images.
- What is an anaglyph?
Left and right images are
blended into one printed or displayed image in red and cyan. If you look at it with red and cyan glasses, you
will see a perfect stereo-image . The cyan glass eliminates the red, the red
glass eliminates the cyan .

Where can I get anaglyph glasses?
Many bookstores or toyshops
sell anaglyph-books with red /cyan-glasses. Surfing the internet for ‘anaglyph glasses’ will give
you many useful adresses like Viewmasterqueen

TUTORIAL
Stereopairs were modeled with the
following 3D-CAD (computer aided design) programs:
- TurboCAD Solid
Modeler http://www.imsisoft.com
- Rhinoceros 3D http://www.rhino3d.com/
- 3ds Max 3ds Max
For making the GIF animations I used:
- Gamani Gif
Movie Gear http://www.moviegear.com/
There are several programs for converting stereo pairs into Anaglyphs. Please read the next tutorial
in which I also give some adresses where to obtain
anaglyph programs.

Obviously a
GIF-animation is made from a series
of stereo pairs, which are converted
into anaglyphs
and then combined to a movie with the GIF animation
program. The animation may contain
movement
of the object(s) in any direction, rotation-loops,
scaling, fly-over and walk-through.

THE IMAGES
NB. Anaglyphs best can be viewed at a distance of about 50-80 cm.

About me 
I
have been interested in computer graphics ever since the beginning of PC-history (1980). In 1982
I
wrote my first 3D- program in Basic for the design of simple wireframes. In the
years thereafter serious
3D-CAD
was mainly employed by professional designers who used dedicated programs on
high
performance computers. Only during
the mid 1990’s, when the Pentium-processors came on the market,
3D-CAD
became within reach of a larger group
of non-professional aficionado's. The
combination of
2
hobbies, 3D-CAD and stereophotography, has led me to these experiments with
computer-anaglyphs.

If you're a
big fan of stereo glasses but your vision isn't quite what it
used to be, you might want to look into getting glasses online There
are many reasons why people wear glasses ,
but regardless as to what the reason is you'll
want to look into eye glasses sooner
rather than later to avoid further damage.There are even designer glasses
for those who are worried
about fashion sense.
