Fractal Music Project
by Albrecht Niekamp 21 Oct '14

21 Oct '14

HI, : after a long time of silence I´m back again with a new project. After my Multifractal Project which has remained unique as it still is the only software creating fractals using up to five formulas simultaneously here is my Fractal Music project, possibly the only one which deserves that name, there are some details they have in common: : It uses a single algorithm to automatically create music of theoretically indefinite size which never repeats itself. The rhythm is my own definition of an endless shifting rhythm originally inspired by Steve Reich ("Drumming") and Terry Riley ("In C") and on their side by African native music for instance by the pygmies. : The melodies- of course being the other half of the structure "shifting melodies" - are created using pixels of a Bitmap (BMP) fractal, which is scanned using the dots and lines of a freely designed IFS fractal. : The basic software - in and out and conversion of a pixel into musical parameters of a single note - originates in the nineties, author David Strohbeen and is not available anymore. : In addition to the image the music is influenced to a high degree by the IFS fractal used, a pyramid for instance creates a harder rhythmic structure, a spiral a softer melodic structure. Listening closely and relaxed you may well find that the general atmosphere of the music is that of the originating fractal. : I converted Jim´s "End of the World" image, FOTD Aug27, loved it at first glance. Thanks for that, Jim. Including links of the WAV files - mp3 is not satisfactory - and the original MID files. Be careful when using Midi: The sound depends on the fonts used and therefore maybe disapointing.The soundfont used is WeedsGM3, google for it. Use only a player that does not change the parameters. The creative player destroys the music, Winamp is ok. : Albrecht Niekamp] : SPIRAL1.IFS { 0.788 -0.424 0.242 0.860 1.649 5.431 0.896 -0.121 0.258 0.152 0.053 -6.722 1.377 0.052 0.182 -0.136 0.091 0.182 6.086 1.568 0.052 } : http://www.crosscanpuzzles.com/Aug13/082713.html https://www.dropbox.com/s/1c7bl26vc44lqy6/120913D3.MID https://www.dropbox.com/s/kvastwz6oopb900/120913D3.wav https://www.dropbox.com/s/odhd6582zzu6cy1/11091301.MID https://www.dropbox.com/s/94mlkbmmdwvydlp/11091301.wav

Fractint under FREEDOS from USB drive
by Timothy Wegner 11 Jun '14

11 Jun '14

This is just a preliminary report, but I think I have found a solution for running the DOS fractint that will work for a lot of people, and one that the Fractint team (such as it is) might be able to support. This makes it possible to run the DOS fractint on modern combuters. The hardware requirements are: 1. Bios that permits booting from a USB drive 2. Graphics with decent VESA video mode support. I bought a bunch of Sandisk Cruzer Fit 8 gb USB drives. These are physically almost too small, they are not much larger than the USB connector itself. I have seen some complaints that some software recognizes them as fixed drives and won't format them. This actually worked to my advantage, because the Award BIOS of my XP machine treated it as a hard drive and let me select the Cruzer Fit to boot from. There's a terrific free tool called rufus available here: http://rufus.akeo.ie/ that runs under Windows (in my case Windows 8.1 64 bit) and can format the USB drive to boot to DOS. I used FreeDOS, but you can use just about any DOS instead. I like using FreeDOS because the default installation seems to do what Fractint needs with extended memory etc. I will verify that this is right. Then I dumped the entire fractint distribution on the USB, with the single difference that I used a fractint.cfg generated by makecfg.exe with the VESA modes for my XP machine. When I ran Fractint, every VESA mode worked, even modes that exceeded the native resolution of my cheap secondary LCD monitor. The problems using higher resolution modes on the same computer under Windows XP vanished. On a related note, I am thinking about putting up a wiki at fractint.net/.org. We could put up instructions like this, par files, images, etc. I wouldn't want to pre-empt others that have fractal sites, but the idea is just to provide more information that would help folks use this ancient DOS program. I would like to hear from anyone else who has used a DOS-from-usb-drive environment to run Fractint. One could literally have a DOS fractint environment booting from on a machine with no hard drives.

Back on 10 March I made a rare posting to this list. I was primarily responding to the query from Tim Wegner about the platform, graphics, and monitor that people use. I said that I am a lurker and I have been subscribed to the Fractint list since 1991, and have followed it closely ever since. I did say to Albrecht that I greatly enjoy his fractals, as I have for more than twenty years those from Jim Muth. I also passed my thanks to the Stone Soup group. My message sparked some correspondence off the list with Hal Lane, mostly about things other than fractals. In turn this prompts me to say a BIG THANK YOU to The Stone Soup Group, and those like Tim Wegner who are still working away Others like Richard who have built new software All those like Jim Muth, Paul Lee and Hal Lane who have discovered fractals, enhanced them, and maintained great web sites, and now of course Albrecht People like Jack of Iradez who have posted animations (I especially like those with baroque music) ... and the rest of the Fractint community.

FOTD for 4/30/14
by Brian Prentice 30 Apr '14

30 Apr '14

I've been enjoying the high quality of the FOTD images for the past few months. Unfortunately, today's image is disappointing by comparison. However, the selected parent fractal does contain some fine details. Here are two examples: http://bprentice.webenet.net/Fractal%20Images/Set%2018/BP_18_85a.png http://bprentice.webenet.net/Fractal%20Images/Set%2018/BP_18_85b.png Brian Prentice

FOTD 30-04-14 (Uncoordinated Color [A-5,M-5])
by Jim Muth 30 Apr '14

30 Apr '14

FOTD -- April 30, 2014 (Rating A-5,M-5) Fractal visionaries and enthusiasts: Today's image rates a totally mediocre 5 in both its art and math aspects. I'm not sure what happened, but the more I worked on the colors, the less satisfying they became. I finally gave up and decided to make the mish-mash of colors the theme of the image, hoping that something worthwhile might emerge. The parent fractal was created when I combined 10 parts of Z^100 with 0.1 part of straight (Z) and added straight (C) on each iteration. This parent is nothing more than a lopsided open circle with 99 tiny buds around its perimeter. Today's scene is located in a small area of interest along the negative X-axis where it emerges from the circular main bay. The name "Uncoordinated Color" describes my impression of the scene. But even though the colors are gaudy and clashing, this does not mean the image is worthless. And the relatively fast calculation time of 1-1/2 minutes makes it a small task to see the meager worth. The web sites will make it even easier. The finished image is online at: <http://www.crosscanpuzzles.com/Archives.html> <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> <http://www.Nahee.com/FOTD/> <http://user.xmission.com/~legalize/fractals/fotd/about.html> Clouds, rain and temperature of 50F 10C made today another day to be forgotten here at Fractal Central. The fractal cats forgot the day early and decided to find satisfaction in their food dishes, while the fractal humans had another routine day. The next FOTD will be posted in about one more day. Until then, take care, and watch your words.

FOTD 29-04-14 (The Fourth Dimension [A-6,M-7])
by Jim Muth 29 Apr '14

29 Apr '14

FOTD -- April 29, 2014 (Rating A-6,M-7) Fractal visionaries and enthusiasts: Today's scene in the East Valley area of the Z^2+C Julibrot was created by the 'ranges' feature of Fractint, a feature that I very rarely use. It is such a rarely used feature that I am not even sure the more current Fractint-emulating programs have the ability to reproduce it. As far as I know, the 'ranges' feature can be accessed only through a command-line entry. The 'ranges' instructions, which are rather complicated, are available in the program documentation. The image slices the Julibrot in an orientation halfway between the Elliptic and Rectangular. The vaguely elephant-shaped open area in the foreground shows that we are roaming the East Valley area. The brilliantly blue bars in the background show that regardless of where the points in the Mandelbrot set begin their journeys, if they do not escape first, they will eventually settle into the same orbits as points that begin at 0,0. And if we look closely, we can actually see the dull red, low iteration foreground stuff gradually merging into the high iteration stuff making up the horizontal blue bars in the background. There is no problem with the colors section of the parameter file. Since the final 242 color registers are all solid black, I have combined them into a single register to save space. I named the image "The Fourth Dimension". After all, the Julibrot certainly does exist in four spatial dimensions. The art earns a rating of an acceptable 6, while the math, which involves four dimensions, rates an improved 7. The calculation time of 1-2/3 minutes is fast enough to keep impatience under control and slow enough to give time to watch the scene unfold on the screen. But calculation is still a chore, and this chore may be avoided by checking the finished image on the web sites. To avoid calculation, check the web sites at: <http://www.crosscanpuzzles.com/Archives.html> <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> <http://www.Nahee.com/FOTD/> <http://user.xmission.com/~legalize/fractals/fotd/about.html> Clouds and rain made today a day to be forgotten here at Fractal Central. The temperature of 48F +9C did nothing at all to help make the day more pleasant. The fractal cats, who are now getting hard to tell apart, spent a little time sulking about the poor weather, but a lot of time working off their dissatisfaction tussling with each other. The humans spent the day pondering the world's human problems. The next FOTD will likely be posted in 24 hours. Until then, take care, and one person can hardly worry about every over-hyped problem on earth.

FOTD 28-04-14 (Fractal Anticlimax [A-7,M-6])
by Jim Muth 29 Apr '14

29 Apr '14

FOTD -- April 28, 2014 (Rating A-7,M-6) Fractal visionaries and enthusiasts: After yesterday's ultimate image, today's near average one seems an anticlimax. I named it "Fractal Anticlimax" accordingly. The scene of the action lies in the distorted East Valley of the parent Mandelbrot set, which is totally corrupted in its depths by cubic energies, and even on its surface is starting to show quite a few cubic tendencies. The art rates a 7. A little more effort might have raised the rating a half point or so. The math rates a 6. Corrupted Mandelbrot sets have been a staple of the FOTD for quite a few years, so the image holds little that has not been seen before. The calculation time of 1-1/6 minutes is quite reasonable. Avoiding the calculation entirely by checking the web sites is equally reasonable. Avoid the calculation by viewing the finished image at: <http://www.crosscanpuzzles.com/Archives.html> <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> <http://www.Nahee.com/FOTD/> <http://user.xmission.com/~legalize/fractals/fotd/about.html> Today dawned clear here at Fractal Central, but clouds moved in as the day progressed, and by mid-afternoon it was totally overcast, with rain predicted by nightfall. The fractal cats exhausted themselves tussling with each other all morning, then slept most of the afternoon. The fractal humans were rather sullen, but considering the world situation, who can blame us. The next FOTD will be posted in about 24 hours. Until then, take care, and let's avoid all the feel-good talk about a bright side.

FOTD 27-04-14 (Saucer Convention [A-10,M-10])
by Jim Muth 27 Apr '14

27 Apr '14

FOTD -- April 27, 2014 (Rating A-10,M-10) Fractal visionaries and enthusiasts: Finally, after all these years, we have a FOTD that rates a double 10. And it took an invasion of flying saucers from outer space to earn this astounding rating. My first impulse was to name the image 'Saucer Invasion', but then I decided to give the aliens the benefit of a doubt, and not automatically assume they are war-like creatures. I finally decided that the aliens are here on nothing more threatening than a galactic convention, and named the image "Saucer Convention". The art rates the holy grail of a 10 because after hours of working on the 48-colors of the palette, I finally got the image to appear almost 3-D photographic. The math earns the same rating because I have no idea what is going on with the math, which appears to have something to do with both Mandelbrot images and Newton's method of finding roots. This could well be the only FOTD that will ever be posted rating a double ten. The flying saucers are all made of some burnished hi-tech copper-colored metal. Some of them resemble huge flying kettledrums, while others resemble thin, flattened dish-like craft, barely able to hold an intelligent alien. It's anyone's guess what the inhabitants of the saucers might look like. The saucers must be mother ships carrying fleets of smaller craft. How else could the many smaller groups flying in formations be explained? The image takes 3-1/4 minutes to calculate, which is likely a lot less than the time it took the saucers to reach the earth from their home worlds scattered throughout the galaxy, if not the universe. See the finished image instantly at: <http://www.crosscanpuzzles.com/Archives.html> <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> <http://www.Nahee.com/FOTD/> <http://user.xmission.com/~legalize/fractals/fotd/about.html> The partly cloudy sky, chilly north winds and temperature of 57F 14C were fine for spring gardening here at Fractal Central today, though not quite so good for the fractal cats, who were unhappy about the chill and waited for the sunshine to become dependable, which never happened. The fractal humans were in kind of a down mood. The next FOTD will in all likelihood be posted 24 hours from now. If not, it will appear in 48 hours.
