Miscellany/!4dMandia/docums/Instruct
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

<<<<<<<<Desktop:>>>>>>>>
Once the 4d fractals icon has been installed on the icon bar, the program is
loaded.
---select---
If you click select on the icon bar icon then you leave the desktop and
enter the actual fractal plotter, to learn how to use this see further down
under the subheading 'Monotasking Fractal Plotter:'
---menu---
Clicking menu on the icon will give you a menu with the following
options: Info �
Default...
Save Choices
Quit
>The quit and info options are obvious (I hope!) so there is no need to
explain them.
>Default... sets the current configurations to the saved settings.
>Save Choices saves the current configurations to disk so that they can be
loaded at a later date with Default...
---adjust----
Clicking on adjust brings up the configuration window. In this window
there are a number of different settings possible. First of all are the
q0-q3, c and d. These are the constants for a four dimensional julia set
fractal. (see 4dFractals file). Click on the icon with select and a caret
will appear in the white icon box. You can edit the values in the normal
way. (Only numbers please!).
The five large icons such as 'Four dimensional' are toggled on and off using
the small green icons to the right of them. The only two that need
explaining are 'Fast' and 'Count Down'; 'Fast' turns the screen off when
processing, this has the effect of speeding up the processor by at least 10
percent. 'Count Down' gives you a count down from 256 to 1 of how many lines
there are left to process, but does have the side effect of slowing down
calculations a small amount.
You may have noticed that if you click on the toggle size icon, you get a
few extra options visible, if not then try now.... There are 13 grey icons
labelled 1-12 and Orig; these set q0 etc to the values on page XII of the
Beauty of Fractals. 'Orig' sets the values to the original pre-set program
values. Some of these (1-12) set the 'Four Dimensional' toggle; this is
because, in my opinion, they look better in this mode. Clicking on one of
the radio icons (yes the funny triangular ones) selects that number of
iterations before the fractal exits a particular iteration.
<<<<<<<<Monotasking Plotter:>>>>>>>>
To enter this environment click select on the icon bar icon.
You must be in a mode with value more than or equal to 12. This is to make
sure that there is enough screen memory reserved.
There may be a pause of a few seconds (usually less than 10) while the base
fractal is calculated. If the 'Fast' option is selected from the desktop
then the screen will blank when processing. Depending on if a Julia set is
selected or not the base will be a Julia fractal.
So that you know which part of the set that you are viewing the xmin&max,
ymin&max are displayed. They show the the bit that is within the flashing
box. You can alter the size of the box using select and adjust. Menu zooms
in on that area and calculates the new fractal.
You can scroll the image up, down, left and right using ', /, z, and x
respectively. The panning left and right is larger due to registers needing
to be loaded from addresses divisible by 4.
If you are in Mandlebrot mode, then if you press 'j' then you can select the
q0 and q1 constants with the x,y positions. It then jumps to the Julia set.
This is useful for selecting nice Julia sets as the best ones are always
the ones nearest the 'Norwegian coastline'.
If you are in Julia mode, then pressing 'm' will make the plotter jump to a
Mandlebrot set using the same ranges. Could be useful I suppose...
R - resets you to the base fractal. (Usually the one which appeared when you
entered the fractal plotter from the desktop).
S - saves the current fractal as a sprite with the file name you supply. If
no directory structure is supplied, then the current CSD and file system is
used.
Q - quits back to the desktop.
Count shows a count down of how many lines there are to go.
That about wraps it up for the instructions. If there are any features not
documented, you should have no trouble in finding out for yourself!
PS if anyone knows how !FastBrot works, please tell me!
