Andrew Que's Fractal Software Manual
Fractal - 256 color fractal explorer
Frac24 - 16.8 million color (24-bit
The fractal software is a DOS program and should run
on any computer that (still) suports VESA.
This program isn't updated anymore, but most of the keys decribed
in the next section should work in the program.
Fract24 is a Mandelbrot Fractal explorer. It runs
in 24-bit color (i.e. 16.8 million colors).
This software requiers only suport of 32-bit VESA modes,
which most video cards are more than capibal. However, new video
cards may not suport this old standard.
NOTE: To run this program, you may need to first create a .PIF
About the color palette:
||Move zoom selection box
||Zoom into selected aira of current frame
||Zoom back %25
||Move left 1/4 screen
||Move right 1/4 screen
||Move up 1/4 screen
||Move down 1/4 screen
|+ and -
||Incresse/decress selection size
|* and /
||Incresse/decress selection size while maintaining center
|< and >
(Use 'Space' to redraw frame in order for this to take effect)
||Redraw current frame
||Save current frame as .BMP file
||Create zoom animation from top to current position
||Change to a diffrent video mode
||Create a new color palette
||Select color smoothness; 1=most corse, 8=smoothest
(Use 'C' after this command to create new color palette)
||Display job progress
The color palette is created at random. The smoothness
of the color is selected by hitting 1 through 8; 4 is default. Typicaly,
the lower into the fractal one zooms, the smoother the palette should be.
However, it all depends on prefrence.
Natraly, when exploring a fractals set, one can expect
to want to save what is on the screen as an image file. This program
can save screens as .BMP files.
The image size higth and width can be between 2 to 16,384.
The file prifix is the name of the output file appended before the file
number; default is "Frac". For example, the prifix "Frac" would first
create "Frac0.bmp". The second image would be "Frac1.bmp".
The number will increment until the a free filename is found. This
way, files never get overwritten.
||Image size X (width)
||Image size Y (higth)
The color palette used for saving is that of the current
When settings are saticfactory, "Enter" will start the
saving process. Now-- the magic: save jobs are processed in the background
so the user can continue to explore. One can queue sevral jobs and
alow them to process while still exploring. 'P' can be used to check
on the status of jobs currently pending. When quiting, all jobs queued
will first be finished. Escape aborts unfinished jobs.
To create a fractal zoom animation file, find an aira
of the fractal to zoom into. Hit 'Z' to begin zoom creation.
A zoom animation file (.ANI) will zoom from the top level of the fractal
to the current frame.
NOTE: Zoom files can take a long time to create, from minutes to sevral
ALSO: Zoom files may consume sevral hundrad megabytes of space.
The image size higth and width can be any value from
2 to 16,384. Keep in mind, the higher the resolusion, the long each
frame of the zoom will take.
||Image size X (width)
||Image size Y (higth)
Gradient refers to how many pixels will be traveled each
frame; default 4.0-- meaning 4 pixel of motion per frame. This directly
equates to how fast the zoom apears to move.
Max loops refers to the color depth. Typicaly, this
value does not need to change and reflects the current color depth of the
current frame. Remember, the high the color depth, the long it takes
to process airas of black.
File prefix is the same as with saveing .BMP files-- it
is the name apended a file number-- the file number being the first free
To begin the zoom creation, hit 'Enter'. Currently,
there is no job suport for zooms, so the zoom is done start to finish after
starting. Progress is displayed in terms of frame number and frame
progress precent. There is no way to determin the number of frame
nesscary to compleat a zoom, so there is no indication of overall progress.
Once an animation file is created, it can then be converted
into an .AVI file with Zoom2AVI or be viewed with ZoomView. The .ANI
file format is proprietary and not supported by anything but these two
Creating a .PIF file
Frac24 is a DOS program and must run as a full screen
application to function correctly. There are two ways of doing this:
one, running Frac24 for a full screen DOS prompt, or by creating a .PIF
To create a .PIF file to run Frac24, right click on Frac24.exe
and goto properties. Under the "Screen" tab is a selection for full-screen.
Select full-screen and hit okay. This will create Frac24.pif.
Now, Frac24 should always come up as a full screen application and function
