LFracs Version 1.0
Copyright © 1996 Alexander Welisch.
All rights reserved, FREEWARE.
DESCRIPTION:
LFracs is a program for drawing L-Fractals (Line-Fractals).
L-Fractals are fractals, that can be generated in the form of a string by
recursive expansion of a short origin code (in the following named
"Axiom"). After that this string can be translated into (drawed as) a pic-
ture.
For example: a = a[0] = "f-f++f-f" (string) <=> __/\__ (picture)
"f" means "draw a short line in the current direction"
"+" means "turn right for w=60 degrees"
"-" means "turn left for w=60 degrees"
If you replace each "f" in a with a itself, you'll have a new string:
a[1] = "f-f++f-f - f-f++f-f ++ f-f++f-f - f-f++f-f"
as a picture this would be:
__/\__
\ /
__/\__/ \__/\__
Again you can replace each "f" in a[1] with "f-f++f-f", and you'll get
a[2] = "f-f++f-f - f-f++f-f ++ f-f++f-f - f-f++f-f -
f-f++f-f - f-f++f-f ++ f-f++f-f - f-f++f-f ++
f-f++f-f - f-f++f-f ++ f-f++f-f - f-f++f-f -
f-f++f-f - f-f++f-f ++ f-f++f-f - f-f++f-f"
so
__/\__
\ /
__/\__/ \__/\__
\ /
/_ _\
\ /
__/\__ __/ \__ __/\__
\ / \ / \ /
__/\__/ \__/\__/ \__/\__/ \__/\__
In case you begin with another Axiom a, you'll get another picture
too.
Besides "f", "+" and "-" there are the special characters
"(" = "Save your present position"
")" = "Go back to the last saved position (without drawing the
path to it), then continue executing the command-string"
With the help of these special characters it's possible to ge-
nerate tree-like fractals too, e.g.:
a = a[0] = "f(ffx)(-ffx)+ffx" (Axiom)
f : "f" (means "replace 'f' by 'f'")
x : "f(ffx)(-ffx)+ffx" (replace each 'x' by 'f(ffx)(-ffx)+ffx')
a[0] as a picture (with start-angle 90°, turn-angle 30°):
\ | /
\|/
|
then is
a[1] = "f(ff f(ffx)(-ffx)+ffx )(-ff f(ffx)(-ffx)+ffx )+ff
f(ffx)(-ffx)+ffx"
and the picture:
\ |\ | /| /
___\| \|/ |/___

INSTALLATION:
LFracs consists of the following files and directories
(packed in the Lha-archive LFracs.lha):
LFracs (Dir) ____ LFracs (Program)
|
|__ Docs (Dir) ____ LF.deutsch.guide (German Documentation)
| |__ LF.english.guide (English Documentation)
|
|__ Catalogs (Dir) ____ deutsch (Dir) ____ LFracs.catalog
|
|__ FracsCodes (Dir) ____ Dragon.code (Data)
| |__ #?.code
| ...
|
|__ FracsPictures (Dir) ____ Dragon12.lfpic (Picture-data)
|__ #?.lfpic
...
LFracs.readme
LFracs-Source.lha
To install LFracs, simply unpack LFracs.lha in your prefered directory.
Then the directory LFracs and the other Files/Directories will be auto-
matically installed as you see above.
Of importance are the directories "FracsCodes" and "FracsPictures"; the
files "#?.code" and "#?.lfpic" are only example-files, they are not ne-
cessary for the correct functionality of LFracs.
The source-code is packed in LFracs-Source.lha (if you don't need it,
you can delete this file).
If you don't speak german, you can delete the Catalogs-Directory and
the LF.deutsch.guide.
