[comp.sys.atari.st] Fractint

Due to overwhelming demand I have placed my incomplete port of Fractint
on terminator. I'm going to be pretty busy for the next few weeks, but
expect to return & finish it around the end of the month. The parts that
work work really well, the parts that don't will lock up your ST.

This is a port of Fractint version 12.0 from MSDOS. The PC authors are
already completing version 14.0. Hopefully I'll be able to merge the
stuff when they're done.

This port was done using gcc 1.37 and 16 bit integers. As with the PC
code, some of the more intense stuff has been written in assembler. I've
clocked it at about 10% slower than an IBM PS-2 Model 70 386 box in the
integer-only routines, so it's reasonably snappy. (Of course, I've also
got a Turbo-16 accelerator...) 

It's not as fast as APFELMAN, oh well. (APFELMAN is this really fast
mandelbrot generator from a German ST magazine. I unfortunately lost my
only copy of it before I could disassemble it... If someone out there
would be so kind as to email me another copy, I'd be grateful.)

Of course, it's got more color than APFELMAN too, so I guess it's a
fair tradeoff.  }-)  16 ugly colors in medium rez, 256 unique colors in
low rez. 4 level grayscale in monochrome. It's cool, it'll be really
awesome when it's finished, but you can sneak a peak at it right now
by grabbing ~ftp/atari/graphics/fractint.arc from terminator.
