fexplore.doc - documentation for using Mandlebroit exploration program.
This program produces colored pictures of fractals on a Tseng-Labs 4000
extended vga card. It displays them with resolution 1024 X 768 with
256 colors. Since computing a pixels value takes so long, special logic
is used so faster pixels are computed first. Basically the program tries to
ignore any "black" areas, since they are time-consuming to calculate. So it
attempts to calculate the colored areas first. Over time it will
cover all points.
To use the program simply run it (redirect stdout if you don't
want to see the complex-number coordinates of the image).

Press Q at any time to quit.
Any other key brings up a box which lets you zoom into a region
of the complex plane (for a new fractal).
The following keys do stuff:
cursors - move zoom box in appropriate direction
x - shrinks view box in X dimension
y - shrinks view box in Y dimension
z - shrinks view box in both dimensions
X - expands view box in X dimension
Y - expands view box in X dimension
Z - expands view box in both dimensions
r - enable/disable color palette rotation
Q - quits
S - saves image in file (can be viewed with DISPLAY).
ENTER - accepts current change box, calculating new image
ESC - exits change box mode
About saving images:
Images are stored in a simple binary file. The format is four doubles
(specifying complex number coordinates of region image is from), followed
by the contents of the graphic frame buffer. So the files get huge: 768K.
Images are automatically saved in filename: IMAGE.n where n==1..18, one
for each image you've saved. You should rename image.* to another name
so the images won't be overwritten when the next series is saved. Note
that display always uses FIRST.IMG as the starting image, so you don't have
to save the first image to disk. See the FDISPLAY program for information
on displaying them.
