What is FractInt and what is it all about?
FractInt is a freeware fractal generator created for IBMPC's and compatible computers.   It is the most versatile and extensive fractal program available for any price.   The authors (of which I am not one), work very hard to keep it that way.   It has many great features and it is still being upgraded and improved by the Stone Soup team.   Keep this link as a reference to stay up-to-date with the latest developments.

Check out "What is New":

Getting FractInt
Version 20.4 of FractInt Now available.

New Image format on these Pages
Years ago, Noel Giffin started the long process of replacing all the GIF images, which were stored and displayed on these pages, over to the Portable Network Graphics (.PNG) file format.   He apologised for any inconvenience, but the issue was being forced by the stance that Unisys had chosen, in regard to LZW patent issues and the use of GIF images on Web servers.   However, this is all irrelevent now, since the U.S. patent expired on June 20, 2003, the counterpart patents in the United Kingdom, France, Germany and Italy expired on June 18, 2004, the Japanese counterpart patents expired on June 20, 2004, and the counterpart Canadian patent expired on July 7, 2004.

The FractInt WWW pages.
Noel Giffin <noel@triumf.ca> maintained the old, original site of this fractal database at spanky.triumf.ca.   In the latter few years, it was mirrored at spanky.fractint.org.   But this current version, which you are viewing now, was a copy from the original site, and is being updated and corrected on a more regular basis than the old site.

Bug Reporting
Yes, even the best of software can still have bugs.   If you come across a bug in the FractInt program you can report it to the developers (The Stone Soup Group) via the web.   The bug report page is:   http://web.ukonline.co.uk/robin.b2/buglist.htm.

Deep Zooming
If you have not seen it yet, it is time to check out FractInt's Deep Zooming capability.

FractInt email listserver
FractInt now has a list-server set up for general questions and discussion about the FractInt program and technical questions about fractals in general.   Here is where to get instructions on how to join the FractInt email listserver.

Searching FractInt's Documentation
Thanks to the Google search engine, FractInt's web-based online documentation now has a searchable index to make finding those hard-to-find references just a little bit easier.

FractInt Contest
FractInt also had a contest page maintained by Jay R. Hill <jayrhill@san.rr.com> during 1998, but it has been copied to this site.

FractInt ScreenSaver
Thore Berntsen <thbernt@online.no> in Norway has written a program which allows you to run FractInt as a Screen-saver with a list of selected parameters.

FractInt under Win95
I have created a short webpage with tips and instructions for running FractInt under the Win95 environment.   These hints were submitted at my request on the FractInt users email listserver.

FractInt Ports in Progress

Ongoing efforts to bring FractInt to Other Platforms

Windows NT port
Turner Rentz <treyr@atr.net> is working towards a windows NT port of FractInt 19.6 for DOS.   Visit his page and check out his progress reports and maybe you might even be able to help.

FractInt for the Macintosh
by Tim Gilman <tgilman@eudaemon.net> In order to graduate from the University of California at Santa Cruz, Tim ported FractInt to the Macintosh as a project for his senior thesis.   His site at www.eudaemon.net/macfract/ is now back on-line and he is again working on the Mac port.   I now have a copy of his last Beta 2 release in the Spanky archives!   Thanks to Aaron Eidinger and Matt Feinstein for keeping me up-to-date on the comings and goings of this link.

XFractInt for Linux
Scott D. Boyd <sdboyd56@swbell.net> has built a precompiled version of xFractInt that will run under:

Basic FractInt for Windows
Paul de Leeuw <pdeleeuw@deleeuw.com.au> has written MANPWin which is a port of the basic FractInt functionality but is written for Win95/98/NT and handles true colour.   He is working with Tim Wegner to get a new windows version up and running.

FractInt for BeOS
Erik Eriksson <ee@hernlabs.se> has an initial port of FractInt to the Be Operating System (BeOS).   The current version is 0.02 and is based on the port to the X/Windows-system (XFractInt) made by Ken Shirriff.

More about FractInt and these pages
There are several ports made to different environments including MS windows for the PC and xwindow systems for unix and they can be retrieved here or from various locations given in the list below.   However, if you are running windows/98 or windows 95 you are probably better off running the latest DOS version under a Windows/DOS box.   The last windows version was developed for windows 3.x and development on that thread has ceased.

This page is currently under construction.   Not all visible links are active.   The intent is to create a good representation of the FractInt program and its capabilities, drawing on selected contributions from users.   To start things off, the FractInt help files have been put in html format to provide a solid foundation to build on.   This was done with the blessing from the Stone Soup Group.   Eventually these pages will expand, taking contributions from other FractInt enthusiasts, reflecting the dynamic and generous nature that this program generates and which makes it great.   One of the first things I would like to add is a FractInt users gallery.   It would be a selection of images and pages of links to other web pages created by FractInt users.   Email me at <noel@triumf.ca> if you have a link that you want included here or an image that you might want to contribute.   There are collections of FractInt Parameter Files, FractInt Formula Files and FractInt Colourmap Files as well as the Fracxtr6 package which is an amazing collection of add-ons for the FractInt program compiled by Dan Goldwater, available in the database.   Feel free to send me more of your favourites.

Dan Goldwater <daniel_goldwater@brown.edu> has found a new home for the Fracxtra web page.

George Martin had written a very useful formula file organizing program, along with a comprehensive collection of formulas.   Thousands of parser formulas have been written by FractInt users, and George's old version containing these formulae is currently available.   This compilation is contained in the file ORGFRM.ZIP, and which constitutes an encyclopedia of formulas written for FractInt.   The compilation includes more than 15,000 formulas, arranged alphabetically by name, and with the original source file shown in each formula by comment.   The package includes a utility program, orgfrm.exe, which copies the formulas of ".frm" files into the compilation, skipping those formulas which are already included in the compilation.   Formula writers are urged to consult this compilation in order to avoid giving a new formula an existing formula name.   George can be reached on compuserve at <ggmartin@compuserve.com>.

Paul N. Lee <Paul.N.Lee@att.net> took over the organization of the original orgfrm files back in July 2000, and maintains a more complete and up-to-date collection at his ORGFORM Compilation web page.

FractInt Tutorial pages
Sylvie Gallet has created a tutorial explaining how to create Psuedo High Color and Psuedo True Color fractals.   Check out "The PHC Tutorial" now!

I have added a small page dedicated to High Iteration Fractals.

Bradley Beacham has kindly agreed to let me recreate a web version of his "FractInt Formula Tutorial".   If you have been looking for information on how to get that new formula of yours into FractInt but could not figure it out, then this is the document for you.   Even if you think you know all there is to know about the formula parser, this makes an excellent review.   Who knows?   You might even learn something.   I did!   If you would rather work with his original document rather then my web version then, that is also available.

William McWorter <mcworter@midohio.net> has created a very nice tutorial on L-systems using FractInt.   It starts off with very simple systems and develops quite nicely into a variety of L-system themes, such as plants, tilings, space-filling curves, true fractals etc.   I think it makes a very useful addition to the growing collection of tutorials and information about using the FractInt program.   If you are interested in L-systems then I am sure that you will find this a fascinating and useful study.

Damien M. Jones <dmj@fractalus.com> has put together a coloring-formula tutorial describing how to implement formula that create unique coloring algorithms for fractals.

Jim Watson has written a version of par2bat in perlscript.   If you run perl on your computer and like to run FractInt from batch files then this a great utility for you.

Janet Preslar created the original and now Jay Hill maintains A list of Resources for FractInt.

Theo Bakker has translated the FractInt Docs into Dutch and put them in MS Word format.   They are now available at Spanky.
