INTRODUCTION:
XaoS is a fast portable real-time interactive fractal zoomer.
It displays the Mandelbrot set (among other escape time
fractals) and allows you zoom smoothly into the fractal.
Various coloring modes are provided for both the points inside
and outside the selected set. In addition, switching between
Julia and Mandelbrot fractal types and displaying planes is
provided. The first version was a poorly written Mandelbrot
view by Thomas later modified by Jan to support high frame-rate
zooming. Other additions were later made including autopilot
(for those of you without drivers licenses), palette changing,
PNG saving, and fractal inversion.

FTP:
XaoS comes in various files:
XaoS-3.0.tar.gz sources
XaoS*.rpm Red-hat packages
xaos30s.zip Sources in zip format for DOS users
xaos30b.zip .exe file for DOS
XaoS30-OS2.zip .exe file for OS/2
Following versions are not done yeat, but I hope they are comming
soon:
XaoS*.deb Debian packages
Macxaos_3.0.sea.hqx Macintosh distribution
xaos30.lzh Amiga binarry. Note that this
file is uploaded only to aminet.
All can be found at following site:
ftp.ta.jcu.cz /pub/linux/hubicka
UNIX version:
sunsite.unc.edu /pub/Linux/Incoming (will be moved somewhere)
tsx-11.mit.edu now in /incoming..will be placed into
/pub/linux/binaries/usr.bin or
/pub/linux/sources/usr.bin
ftp.x.org /contrib/graphics
MS-DOS version:
ftp.simtel.net /pub/simtelnet/msdos/graphics

REQUIREMENTS:
XaoS uses floating point math for its calculations. This may
be slow on some computers. The program was developed on
a Pentium running at 120 MHz, but it can work quite well (20fps)
on 486Dx/2. I also received nice letters from users using
XaoS at 386/40 or so. Coprocessor is _REALLY_ required.
Faster computer is better so alpha/600MHZ recomended.
To compile XaoS you need ANSI compliant compiler with _GOOD_
optimizations. Unix version uses configure script. Other
platforms uses different ways. GNU CC is highly recommended.
Graphics drivers usually have some additional requirements.
(for example xlib for X11, djgpp and allegro for dos port)
Also fast malloc/free routines are recomended because they
are called quite often (10 times per frame). For full
featured XaoS (with image saving code) you also need zlib
and libpng.
MAILING-LIST:
XaoS now have following mailing lists at
majordomo AT horac DOT ta DOT jcu DOT cz

this list is for general xaos discusion
(ideas, questions, bugreports..)
xaos-announce
keeps you informed about new versions
