Fractint is a freeware open source software package that can render and display many kinds of fractals. Its name comes from the words fractal and integer, since the first versions of it computed fractals by using only integer arithmetic (fixed-point arithmetic), which led to much faster rendering on x86 computers without math coprocessors. Since then, floating-point arithmetic and "arbitrary-precision" modes have been added, the latter of which emulates an arbitrarily large mantissa in RAM. The arbitrary-precision mode is slow even on modern computers.
Fractint can draw most kinds of fractals that have appeared in the literature. It also has a few "fractal types" that are not strictly speaking fractals, but may be more accurately described as display hacks. These include cellular automata.
The program originated on the MS-DOS platform, but has since been ported to X and Microsoft Windows. It is currently at version 20.0, and no new versions have been released for several years. As of early 2006, the Microsoft Windows version does not include arbitrary-precision mode, and the X version is somewhat counterintuitive to use.
[edit] History
Fractint originally appeared in 1988 as FRACT386, a computer program for rendering fractals very quickly on the Intel 80386 processor using integer arithmetic. Most '386 processors of the era did not come with floating point units (387), so the integer approach was much faster.
Although the early versions of FRACT386 were written by Bert Tyler, they were based on an even older program for rendering the Mandelbrot set called DKMANDEL.ARC, which was written by J. Douglass Klein. By the time of the FRACT386 v2.1, which was the first popular version of FRACT386, no original code from DKMANDEL remained.
In February 1989, the program was renamed Fractint.
It was written and maintained by the "Stone Soup Group" who took their name from the fable of the stone soup. Along with Emacs and NetHack, it is one of the oldest still-maintained free programs.
