No, this isn't about the M-set movies mentioned recently.
What I am seeking is a list of interesting places in the
Mandelbrot set to magnify. I have over a dozen or so,
mostly from Peitgen's & Richter's book, but I am looking
for more. So, anyone find anything great, or know of
any places that has this info?
I am also interested in good locations for Julia curves.
E-mail preferably, I'll post a summary if there's a summary
worth posting.
Thanks

We have an experimental graphics machine here at the University of North Carolina (Pixel-Planes) which allows you to walk around the Mandelbrot set (and Julia set) in real-time under joystick control. If you're ever in Chapel Hill, come by and have a look.

I saw the program FRACTINT mentioned a few articles back. This is an
excellent program for the IBM PC-types. The Mandelbrot implementation
it uses is the familiar iterate-until-magnitude-greater-than-2
algorithm, but it is implemented in 16- and 32-bit fixed-point(?)
and/or integer math. thus, when running it on a 286 or 386, it can do
a full 360x480x1024iter Mandelbrot in about 30 seconds. [well, that's
on a 386SX @16.7MHz]
but that is still pretty fast. they did the same thing to their julia
set [even faster than the MB set!], and to their newton-solution
technique. they still have a floating-point implementation of julia
and MB sets built into the program, for the sole purpose of:
"If you feel the need to reminisce about the days when
men were men, computers were computers, and fractals
took forever to generate."
sigh.
this program also includes lambda sets, lambda-sine, newton,
newton-basin-of-attraction, and 'plasma' clouds. in addition, it
supports a large amount of video modes, cycles colors, can save any
picture do disk, and can map any saved picture onto a sphere or do
other nifty 3d projections.
the C source code is avalable, but i think it is currently being
distributed over Compu$erve... i haven't looked that hard tho.
happy hacking,

Yes, fixed point. Note that when the constants in this program are non-zero, the results are not the same as the older versions (or any other program I've seen). To see this use the 't' command, select type 'mandel' and set Z0=.3 and Z1=.5 with any version previous to 10.0 and with 10.0. I have sent Email to several of the authors, but haven't gotten a reply yet. -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
