Date: Fri, 4 Oct 1996 10:16:48 +0200 (MET DST) From: Jan Hubicka To: djgpp-announce AT delorie DOT com Subject: XaoS - Fast realtime fractal zoomer Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII >X a o S< CREDITS: Jan Hubicka (hubicka AT limax DOT paru DOT cas DOT cz) Thomas Marsh (amadeus AT bga DOT com) (not avaiable for now..) INTRODUCTION: XaoS is a real-time interactive fractal zoomer for DOS, Plan9, X11 and SVGAlib. 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 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, GIF saving, and fractal inversion. WHATS NEW: This is mainly bugfix release but some of new features were added too: o New recalulating with non rectangular pixels. (for full screen modes) great for modes X :) o New palettes with white background o Added coprocesor configuration into MS-DOS port - some coloring modes are MUCH faster because of no more SIGFPE ignoring.. o Added support for 1280x1024 and 1600x1200 into MS-DOS port o Default type changed back to double because long double is non standard o 9x15 font changed to more compatible and better looking fixed. o First release of plan9 port (very interesting OS see http://plan9.att.com..trial version if free)-not complette yet..colors looks ugly and keys like arrows does not work.. someone who can help me? o Added key defines for old svgalib compatibility. REQUIREMENTS: XaoS, by default, uses floating point math for its calculations. This may be slow on some computers. The program was developed on a Pentium running at 100 MHz, so we can't guaranty that it will run well on any slower system. If you just want to catch a cursory glance at XaoS' capabilities on faster systems then you might try compiling it for fixed point arithmetic by editing config.h accordingly. To compile XaoS, DOS, Plan9 or UNIX and X11 (or SVGAlib for Linux) is required. We are discussing the possibility of porting it to OS/2. Your C compiler must be ANSI compliant. GNU CC is highly recommended. An 8-bit display is required at this point since we haven't coded for TrueColor displays yet. FTP: XaoS comes in various files: XaoS-1.2.tar.gz sources XaoS*.rpm Redhat packages Debian packages is coming soon xaos12b.zip MS-DOS binaries xaos12s.zip MS-DOS sources(unix one works too..just for those w/o tar and gzip) All files are placed at: ftp.ta.jcu.cz/pub/linux/hubicka UNIX releated: sunsite.unc.edu/pub/Linux/Incoming...will be moved tsx-11.mit.edu ftp.x.org/contrib/graphics Redhat package: ftp.redhat.com/pub/contrib/... DOS version: ftp.simtel.net/pub/simtelnet/msdos/graphics HOMEPAGE: Europe: http://www.paru.cas.cz/~hubicka/XaoS/ U.S.: http://www.realtime.net/~amadeus/XaoS/ (it is omposible to update it now. Pleause use European one) INSTALL: Installation methods are described in the file "INSTALL". USAGE: XaoS has no command line options as of yet. It is one entirely self contained executable. Runtime help is provided by typing "H". THANKS TO: Stanislav "XaoS" Mikes - for the name of our program Borislav Deianov - for sharing ideas Isaac Newton - for discovering his method Benoit B. Mandelbrot - for ordering the Julia sets Linus Torvalds - for the best operating system Tim Wegner & Bert Tyler - for Fractint Darryl House - for making Fractint's code readable NO THANKS TO: Bill Gates >X a o S<
