TTFRACT V1.3
============
TT Fractal generator program
Programed by Dany Roth version 1.2 October 7th, 1991
This program was written for the Public Domain!
This program can be distributed and/or copied without any licence
or fee (unless for the saving media), but must include the
accompanying documentation "TTFRACT.DOC".
General Information
===================
This program will run on ATARI-TT in any of the six resolutions
(At least could be tested on those but, can probably work on the
color big screens, since it uses GEM for screen information).
***************
* NEW in V1.3 *
***************
1) Several bugs were removed
2) RSC file is now integrated in the PRG
TTFRACT description:
====================
Choosing MANDEL will open a dialog box asking for iteration
depth.
This is choosen using a click on up/down arrow to increment/dec-
rement iteration depth +/- 1. When finished click Accept or Can-
cel. The screen will clear and the fractal will be drawn.
You can wait till the drawing has terminated or press space-bar to
halt further drawing and be returned to the menu screen.
In case of choosing JULIA a dialog box for setting the constants
A and B will appear before "Iteration-depth dialog box", the values
will be incremented/decremented by 0.0005.
A and B are for Z=Z**2 + C (C=A+Bi)
JULIA1=> Z=Z**2+C
JULIA2=> Z=Z**3+C
JULIA3=> Z=Z**4+C
JULIA4=> Z=Z**5+C
JULIA5=> Z=Z**6+C
JULIA6=> Z=Z**7+C
(the MANDEL1...MANDEL6 are as JULIA sets above)
One can zoom into the previously drawn screen by choosing Zoom
from menu. A dialog box asking for changes in iteration depth will
appear. The menu will disappear, position the mouse on start (left
upper corner) of block, hold down left mouse button and drag a box
to the size you want the zoom to be.
In case of impatiancy one could press R during drawing of fractal,
in this case drawing will stop and the mouse pointer will appear.
SAVING:
=======
Save NEO:
This will save the drawn fractal in normal NEOCHROM format (In
case of TT-Graphic modes not all the old software will be able to
load or understand those formats).
Save IMG:
This will save the drawn fractal in standard GEM-IMG format (It
was found that alot of old programs assume that a GEM-IMG must be
monochrome and very small!!, programs as Calamus SL seem to have
no similar problems, also concerning NEO formats).
GRAY:
=====
Used on color monitors to switch between color or gray represen-
tation.
TT_DUMP:
========
If TT_DUMP.ACC is installed (ACC to screen dump on HP laser jet)
the entry will be active else disabled.
It will set menu bar off and switch into fractal page. After that
it will communicate with TT_DUMP.ACC available separatly to
produce printout on HP Laser Jet II and compatible.
The program was written in ANSI-C using Lattice C V.5.06.02 avai-
lable from HISOFT (DEVPAC assembler remember?) in the far away
England.
Since the program is under further development I will appreciate
any remarks, comments ideas ...(BUT NO MONEY!)
