The principles of random dot stereograms were
first invented by Prof. B. Julesz in early 1960s who made the dual image
random dot stereograms. In 1989, Prof. C. W. Tyler made a significant
improvement to produce single image random dot stereograms which
are now found in many popular 3D pictures books around the world (see TIME
(1994) Oct.3, p.52).
The technology for constructing those 3D pictures
could be applied in the following areas:-
-
Research, Education and Industry: 3D mechanical
model, electronic circuit board, architectural model, R&D and educational
demonstration model with 3D viewing.
-
Information and encryption: protection of
data storage.
-
Medicine and Psychology: a very useful tool
for Visual Science research as well as the brain behaviour research.
-
Fine Art: 3D pictures, postcards, design,
advertising, wallpaper, tiles.
There are two usual ways to view the stereograms
which must be viewed horizontally:
-
Wall-eyed (or Far-eyed) Viewing Method
-
X-eyed (Cross-eyed) Viewing Method
About 10% of the population are always unable
to view the stereograms because of their eye defect or other reasons. |
