FOTD 03-11-07 (Eyes of Taurus [5.5])
by Jim Muth 03 Nov '07

03 Nov '07

FOTD -- November 03, 2007 (Rating 5.5) Fractal visionaries and enthusiasts: In the mail today I received the holiday offering from a popular- ized science book club I belong to. Most of the books offered were of the typical 'learn string theory in a day' variety. But on the back page of the advertising magazine I saw an offer for a $199.00 book titled "The New Encyclopedia of Unbelief", which when ordered for the special club member's price of $124.99 will come wrapped in holiday gift wrapping. It seems to me like some kind of macabre joke, giving someone a book about Atheism for Christmas. It is probably no accident that the book is published by a well-known skeptical organiza- tion that exposes phony psychics and generally debunks claims of the paranormal. Their real agenda is the promotion of Atheistic Rationalism. Hmmmm . . . I wonder if hard-core skeptics believe in the reality of fractals. Anyway, it doesn't matter what skeptics believe, since I am a true-believing born-again believer in fractal reality -- at least a true believer in the reality of pictures of fractals. And to prove my point, I have included the parameter file of a fractal that was created by the formula Z^(1.5)+C. To create the parent fractal I turned to the MandelbrotBC1 formula, which is a more versatile version of the MandelbrotBC2 formula. To add extra interest, I calculated the formula with the function set to 'cotan', rather than the hard-coded 'floor' function of the MandelbrotBC2 formula. The result is a totally different fractal. This new fractal is little more than a shapeless bay surrounded by filaments and chaos. Today's scene is located in a small, narrow, pinched-off valley on the northwest shore line of the shapeless bay. I named the image "Eyes of Taurus" because of the multitude of bulls-eyes scattered throughout the scene. The little minibrot just to the upper right of center adds a point of interest. But despite all this, I could not bring myself to rate the scene any better than a 5.5, and a half-point of this is due to the extra effort I put into the coloring. At least not too much time will be spent calculating the image. The included parameter file runs in 5 minutes. And for those who do not calculate, the finished image is available on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Only a slight nip in the air kept Friday from reaching total perfection here at Fractal Central. The cloudless skies and high temperature of 55F 13C made any outdoor activity except swimming a pleasure. The fractal cats voiced their agreement as they asked for their tuna. Other than the book offer, my day passed with nothing worth mentioning taking place. The next FOTD will be posted in more or less 24 hours. Until then, take care, and be where it's at.

xfractint-3
by John Wilson 02 Nov '07

Hey! Riko Voipio's xfractint version 20.4.00-1 is up and running in my Ubuntu computer. Don't know what I was doing wrong in my earlier attempts... might be as simple as which screen I had the focus on. Anyway I have only one problem left, (other than cleanup of my manual installation). My colours are all in the blue and green end of the spectrum. Got to investigate that, otherwise all looks good. John W.

Xfractint_2
by John Wilson 02 Nov '07

Well, well, well. As I mine through the innards of Ubuntu Gutsy, I find that the Synaptic Package Manager supports xfractint version 20.4.00-1, maintained by Riku Voipio in Finland. I installed this through the Manager with partial success. Upon activation, the initial scrolling screen appears in my Terminal and F1 starts up the "help" screens. However, the following screen remains black and any further commands return me to the prompt. My first, abortive, attempt to install xfractint was a manual installation of Scott Boyd's xfrac-binary-20.2.04.gz executable. As far as I know, this is still buried in the innards of my machine and I've no idea of how to clean it all up! (This is something which baffles me about Linux... how to manage an application for which the files are strewn around the four corners of the file system.) The package manager will look after removing Riko Voipio's xfractint for me. Scott Boyd's xfractint page mentions that "Xfractint was updated to Fractint 20.2.04 by Tim Wegner, Jonathan Osuch, and others." So where does Riko Voipio's xfractint version 20.4.00-1 come from? Puzzled JohnW.

FOTD 02-11-07 (Ambiguous Blobs [7.5])
by Jim Muth 02 Nov '07

02 Nov '07

FOTD -- November 02, 2007 (Rating 7.5) Fractal visionaries and enthusiasts: To begin today's venture into fractal land, I mixed 1.5 parts of (1/Z) with straight Z and added (1/C). The combination produced a hyperbola with the open end facing west. On the surface, the edges of this hyperbola appear smooth and featureless, but a closer examination reveals that the edges consist of the typical Mandelbrot buds and their radicals. Today's scene is located in a kind of elephant trunk in the narrow band of Mandel stuff on the northern side of the parent hyperbola. It is rather surprising that the midget in today's image has an East Valley appearance, since the area in which it lies bears no resemblance at all to a valley. When I saw the four flat disks that appear to stand out in front of the rest of the scene, I named the image "Ambiguous Blobs". And since I did put a bit of extra effort into the coloring, I decided to reward myself with an extra half-point rating. The rating of 7-1/2 equals a little more than only an average amount above the FOTD average. The calculation time of 3-1/2 minutes is within reason for the rational fractalist. Those who are not rationalists may view the finished image without effort by going to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Thursday, the day on which we honor all the saints, began with heavy clouds here at Fractal Central. But at noon the dark clouds quickly moved out, leading to a very pleasant autumn afternoon, with brilliant sun on the colorful trees and small fluffy clouds in the background, while the temperature reached 61F 16C. The fractal cats, not even being close to sainthood, found their share of mischief. For me, the day was busy enough to prevent boredom and still leave time for the day's FOTD. In all probability, tomorrow will be the same. Until next time, take care, and save the best for last.

Xfractint
by John Wilson 02 Nov '07

I wonder if anyone on the list has installed Xfractint in Ubuntu? I've just abandoned Microsoft, and my Media Centre machine is now totally dedicated to Ubuntu 7.4, (Gutsy Gibbon). Very much a Linux newbie, I've downloaded Xfractint and tried to install it and run it in Terminal. It doesn't... yet! I just get a very transient message that Xfractint can't find something... a .HLP file is what it looks like, although why that should influence anything I can't say! I installed in my Desktop and maybe this is the problem? Help! John W.

. Someone asked, so... The fractint PAR for the buddhabrot is: Buddhabrot { reset=2004 type=mandelcloud passes=1 center-mag=-0.300522/-4.44089e-016/0.8079007/1/-90/-1.23373533611470521e-014 params=751 float=y maxiter=751 fillcolor=0 inside=0 outside=summ sound=off colors=200A84<20>oiPqjQslR<3>zsW<25>CB6A95874653442220000400<23>o00q00s00<3>z00<25>C00A00800<3>000<2>554776998BBACCB<18>\ iihjjillk<3>ssr<25>BBA998776<2>221000011<24>0bn0cp0er<3>0ky<25>09B089067<2>021000210<2>863 } The colors were saved out as a map, and referenced in sstools.ini. Thus it is simpler: Buddhabrot_ { reset=2004 type=mandelcloud passes=1 center-mag=-0.300522/-4.44089e-016/0.8079007/1/-90/-1.23373533611470521e-014 params=751 float=y maxiter=751 fillcolor=0 inside=0 outside=summ sound=off } A BASIC script prints out the whole thing as a literal string, but the params and maxiter numbers are variables; a simple loop varies them from 2->751 and prints out all the PAR entries to one file, along with a BAT file which runs fractint and references the entries sequentially. XFRACTINT? I tried it a few years ago when I was investigating linux. It didn't seem to be as fast or as versatile as DOS fractint so I shelved it. I'm still waiting for 64 bit Fractint ... In the mean time, I've finally got ultrafractal to read some of my fractint pars, like for the universe sequences, but I have to hack them up a bit. Maybe I can re-render the U3 viddie in 32 bit color if I can get it right. But I don't know if current systems can be run 24/7/365; they are not as robust as older systems and tend to overheat. I can fix that, but the rendering time should be much quicker since a windows app can take advantage of the full proc capabilities and 32 bit memory addressing, but they actually render slower than fractint. Don't know why that is ... JoTz .

FOTD 01-11-07 (Terraces Without End [6])
by Jim Muth 01 Nov '07

01 Nov '07

FOTD -- November 01, 2007 (Rating 6) Fractal visionaries and enthusiasts: Today's image returns us to the sqrt(2) Mandeloid as it appears sqrt(2) levels up the complex logarithmic ladder, where it resembles a limbless torso. Today's image is located in a rudimentary East Valley in the southeast part of the largest bay. Since I feel I am overdoing these low-order fractional images, I could rate today's effort no higher than a 6. I named it "Terraces Without End" because of the terraced effect created by rendering the image with the outside set to 'tdis'. The somewhat excessive calculation time of almost 12 minutes on the fast machine and one hour on the slow unit is due to the unusually large maxiter of 150,000. To save time, I have sent the finished image on ahead to Paul at the FOTD web site, where it may be viewed without needing to run the parameter file. The web site may be accessed at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Near perfect weather here at Fractal Central on Halloween kept the streets filled with assorted T-or-T ghosts and goblins, while the fractal cats kept themselves busy watching and chatter- ing at the local pigeons. My day was neutral, which is all I can say about it. The next FOTD is due in 24 hours. With any luck, it will actually appear at that time. Until then, take care, and did fractals have a special creation or did they just happen? And what's the dif- ference?
