Stereogram
~~~~~~~~~~
What is stereogram?
---- -- -----------
Stwreogram is a fractal post-image processor for creating 3D random dot
stereograms out of images. A colour on the original image is translated into
depth on the stereogram. When rendered, try looking 'through' the monitor, and
you will see, after a lot of staring, a 3D picture in front of you.
Using Stereogram
----- ----------
First render a picture - use a Mode 13 Mandelbrot as an example. Then, select
Stereogram, and press redraw. If you are using a 14" monitor, and stare through
the image, you should see a 'sunk in' Mandelbrot. This takes a lot of practice
to get right, and some people cannot do it anyway.
The function does not multitask, as it is so very fast anyway.
Data Variables
---- ---------
In the data window, you will see: Mon. Width:
This is the width of the VISIBLE area of the screen in the desired viewing
mode. The default is for modes 13/15 on my Phillips model.
X shift:
This can be positive or negative, and adds an offset to the image on the X
axis. Under normal circumstances, you should not need to use this.
Eye Dist:
This is (roughly) the distance between your two eyes, which will (hopefully!)
remain constant over time. The default is, so far as I can tell, the distance
between my eyes, which works, so I'm leaving it alone.
Copyright
---------
The copyright of
RayCast, Stereogram, Sierpinski
belongs to Neil A Carson. No part of the code may be used in any other program
whatsoever without the author's permission.
However, Mike Curnow's word is my word, so if he says you can do something with
it, then it's fine by me.
Source code is obtainable together with the source for the rest of Fractal
(since it is not much use on its own) from Mike (with his permission) at the
address below.
