### RDA Viewer by Barton Stander.
Version 2.6
Text can be converted into an RDA. This version allows you to enter
text, but
does not convert it to an RDA. This option is solely for the
registered versions.
For all of you that have registered, thank you. Please send a disk for
free upgrade.
For those of you that registered and purchased the source code, you
will be sent
the new code directly and there is no need to send a disk for this
upgrade.
Thank you for all of your support, and those of you that haven't
registered should
join the rest.
For the educators using this product as a tool to help understand
mathematical
equations, there is now available a special class room price for many
copies.
Thank you for your support also.
If the image is damaged (RDA image), just hit applekey-r to redraw the
image.
Damage to the image can occur if it is generated in the background and
something
is overlapping the RDA window.
The Subsample in the Editor allows you to do a rough calculation to
see
how it will look before doing the longer calculations for every pixel.
Instead
of calculating a new Z value for every pixel (this would be 1), it
could calculate
the Z value for every 5 pixels ( a setting of 5). Another way to put
it is that if
the setting is 5, the resolution of one pixel is now the size of 5
pixels. Experiment
and you will see. Do something easy like just plotting x (z = x).
The range of the x and y values are -1.0 to 1.0 for y, and -1.6 to 1.6
in x.
Files can now be opened on any drive in any folder.

### INTRODUCTION to RDAs
Random Dot Autostereograms (RDAs) are images that contain three
dimensional
information in a single image instead of a pair of images typically
refered to
as a stereo pair.
When the RDA is properly viewed, the random dots appear to come out of
or go
into the viewing plane (Monitor, Paper, etc...).
To view an RDA one must focus infront of the viewing plane, or behind
the
viewing plane. Focusing in front of the viewing plane is done by
becoming crossed eyed.
Focusing behind the viewing plane is done by becoming wall eyed.
The RDA Viewer can read RDA images. It can also display PICT images.
The Viewer can
generate the same RDA images as provided. Generation takes a
considerable amount of time. If
you are running a 68000 or a machine without the 68881 FPU, then you
shouldn't generate any
images unless you have plenty of time (30 minutes or more). The
advantage of generating images is that
you can display the contours of the data.
The RDA viewer has an equation editor. You can enter in your own
mathematical equations
and view their results as an RDA or as a contour.
The Viewer can save the images generated as PICT files, and examples
can be downloaded.
Open an RDA image with the Viewer Application. I suggest the file
"circle.PICT".
Under the View menu, select "Show Repition Rate". This is the amount
the eyes must be crossed
or wall eyed to view the image.
The two dots shown by Show Repition Rate are a guide to help you
focus. Focus your eyes (by
crossing of walling) util the two dots fuse to make three dots, on
focused in the middle, and
two fuzzy dots, one on each side of the focused middle dot.
If you see four dots you have not crossed or walled enough. Sometimes
it helps to put your
finger in front of the image and focus on it, and in the background
notice if there are three
dots yet. Move your finger closer and further away until you have
three dots.
Once you have three dots, you must keep them focused and start to look
down and towards the
middle of the image. You will see the dots on different levels, at
different depths.
