. 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 .

FractInt for Windows (beta 4) -- open for testing
by Richard 13 Aug '07

13 Aug '07

Welcome to the FractInt Makeover! For those of you on the fractint list that may not have heard, I've been overhauling the FractInt source base to move it out of the 16-bit DOS world. Things have been progressing nicely and I'm now at a point where I think widespread testing would be helpful. Download and install beta 4 of FractInt for Windows: <http://tinyurl.com/26dvd7> I've just resubscribed to the fractint list so you can send bug reports to me or to the list. If you have any doubt, just send any bugs to me. A memory dump file will be produced upon a crash, but that shouldn't be happening anymore :-). This is what I would call "Phase I" of the overhaul. It is a migration of the existing DOS source base to a 32-bit Windows application. The user interface looks and acts like DOS because it is just a port of the DOS ui. A minimal amount of "Windows-ification" has been done, but you'll notice a lack of normal Windows things like a menu bar, context menu, paying attention to the mouse, dialog boxes, etc. The next phase will be to backfill these changes into the X Window System version to make all these features available to xfractint. Once that is tested, the beta will be over and a new release made. Known Issues There is no sound output support. There is no mouse support. Panning and zooming is by keyboard only. Video modes with pixel dimensions other than 4/3 aspect ratio assume non-square pixels. The images all render fine, but they appear stretched or squashed. The choice of resolutions in fractint.cfg reflect this. With debugflag=10000, error messages are reported for disk video mode when: start fractint, pick any disk video mode (e.g. 320x200), let it render, wait for completion, then go to the <v> screen, change 320 to 32, submit it. Without the debugflag settings, FractInt for Windows will most likely crash. This problem is present in the DOS fractint and not a result of the port. There are a few gaps in functionality associated with fractal types that were computed via assembly language, but these were mostly integer versions of some of the more common fractal types. If you encounter this situation a message will be displayed informing you that you should switch to floating-point for a useful image. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

FOTD 27-05-07 (Perturbed Brotrise [Not rated])
by Jim Muth 03 Jun '07

03 Jun '07

FOTD -- May 26, 2007 (Not Rated) Fractal visionaries and enthusiasts: Today was quite busy here at F.C., but I still found time for a quick visit to the Hyper-Mandelbrot set, where I checked the hole at the center of a midget on the filament extending from the large north bud of the Hyper-M-set. I pictured the hole just as it was ready to be engulfed by the encroaching chaos. With almost no effort being put into the image, I could not honestly give it a rating, though I did name it "Perturbed Brotrise". The image is a very fast one, finishing in a mere 24 seconds on the fireball P-2000 machine. On the snowball P-200 unit, it would take about 2 minutes to finish. But why not forget calculating the parameter file? The finished image is or soon will be available for instant viewing on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> A very warm muggy day with a temperature of 84F 29C was refreshed by an afternoon thunder-shower, which dropped the temperature to 68F 20C. The fractal cats looked out the window long enough to see that it was raining heavily. Then they returned to their mischief. My day was quite busy. The next FOTD will appear in 24 hours. Until then, take care, and live your life like a fractal.

FOTD 01-06-07 (Searching for Silk [5])
by Jim Muth 31 May '07

31 May '07

FOTD -- June 01, 2007 (Rating 5) Fractal visionaries and enthusiasts: It's a new month here at Fractal Central, where our job is to try to make silk purses out of the sow's ears some customers send in. Sometimes we succeed, sometimes not. In today's image I have tried once again to make something of nothing. The nothing is the midgets I have so far found in the Mandeloids between 1 and 2; the something would be to actually find a really great midget in one of these fractals. Today I tried, with only a bit of success, to make something of a tiny midget I found in the debris on the northern side of the main bay of the parent fractal that is generated when the formula Z^(1.5)+C is reiterated 439-1/2 levels down the infinite complex logarithmic ladder. What I got was just another bunch of broken filaments converging on a tiny midget in the center, which is so small that it might as well be invisible. By working on the coloring a bit I was able to rate the whole thing at a 5. But by FOTD standards, any rating below a 6 is unacceptable. I named the image "Searching for Silk", which was what I was doing when I stumbled upon the midget. Am I ready to give up the so-far-fruitless search? No way! But I will confine my efforts to the Z^(1.5)+C fractals until I find something worth the effort. In fact, I already have an idea for tomorrow's FOTD. Today's image is lightning fast. It calculates in under one minute. And just as fast and even more convenient is going to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the completed image there. Let's face it, the weather has been a bit too perfect here at Fractal Central these past several weeks. True, the sunshine was plentiful on Thursday, but the high temperature of 91F 33C and noticeable humidity were just too oppressive to be called perfect, and the lack of rain is causing real concern among the area farmers. The fractal cats only concern was the noise from the road work 1/2 block up the street. But even that minor annoyance went away when the workers quit for the day at 5pm. As for me, the day was acceptable, neither great nor terrible, but simply acceptable. The next FOTD fractal will appear in 24 hours. Until then, take care, and when measuring the volume of a theoretically perfect vacuum, exactly what are we measuring? In other words, how can there be more or less of nothing?

FOTD 31-05-07 (Still Searching [5])
by Jim Muth 30 May '07

30 May '07

FOTD -- May 31, 2007 (Rating 5) Fractal visionaries and enthusiasts: I never give up searching for a great midget in a Mandeloid fractal with an exponent of Z between 1 and 2. The search continues in today's image, which lies in the Z^(1.5)+C Mandeloid as it appears 55 levels down the logarithmic ladder. The midget at the center is a bit too gaudy for a rating higher than a 5. I named the image "Still Searching" because I am still searching for that elusive spectacular scene in a Mandel- oid of the order 1.n. I will continue searching indefinitely, for I will not fail until I stop searching. Today's image calculates in 7 minutes on the fast machine. On the slow machine it would take around 1/2 hour to finish. So why not forget the burdensome task of calculation and view the finished image on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Another perfect day went un-appreciated here at Fractal Central on Wednesday. There have simply been too many perfect days during the past month. At least today's fractal has enough imperfections to avoid boredom. Speaking of fractals, the next one, the first for the month of June, will appear in 24 hours. Until then, take care, and who knows where fractals end.

FOTD 30-05-07 (Pop-a-Brot [?])
by Jim Muth 29 May '07

29 May '07

FOTD -- May 30, 2007 (Rating ?) Fractal visionaries and enthusiasts: I see that the FOTD for Jan. 29, 2002 has received an unusually large number of hits. But I can't see why. In my opinion, the image, which rated a 7, is above average, but many other past FOTD images have also rated a 7. I guess the style of the image reminds viewers of the 60's, a time that is long lost in the past. As a matter of interest, the discussion for that FOTD mentions the futility of trying to make a living selling fractal prints. Today's image also has a bit of a pop-art look about it. The pop effect is perhaps not as obvious as that of the 5-year-old image, but it is still apparent. In recognition of its pop-art style, I named today's image "Pop-a-Brot". And when it came time to assign a rating, I was totally undecided, so I rated it at a big question mark and let it go at that. Today's FOTD is an evaporated image that was produced by combining 2 negative parts of Z^(-2.2) with 1/2 negative part of Z^(-4.4), and then adding (1/C). The parent fractal is an indescribable thing with X-axis symmetry. Today's scene is located in the northeast suburbs of the parent. The calculation time of 56 seconds is true on the fast 2000mhz fractal computer. The slower 200mhz machine will take around 5 minutes to complete the job, but even 5 minutes is a short wait in the slow world of fractals. The minor wait may be totally eliminated however by going to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the image there. Tuesday was an absolutely perfect day here at Fractal Central, and the fractal cats agreed. As for me, I find one perfect day after another rather boring. I guess there's no way to make everyone happy at the same time, which raises thoughts about the claims of absolutely perfect happiness for everyone in heaven. But that's a topic for a future philofractal discussion. My immediate plans are to post another fractal in 24 hours. So until then, take care, and be with fractals wherever you may go.

FOTD 29-05-07 (Once a Rectangle-- [5])
by Jim Muth 28 May '07

28 May '07

FOTD -- May 29, 2007 (Rating 5) Fractal visionaries and enthusiasts: There is a curious rectangle in the Julia set of the formula Z^(2.003)+C with initial C set to -1.7453,0. Its Z coordinates are 0.00019,0.07388. It is best seen at a magnitude around 100. I have featured this Julia rectangle and various distortions of it many times over the 10-year life of the FOTD. Not surprisingly, similar rectangles surround the Mandelbrot midgets in the -1.7453,0 area of the Z^(2.003)+C Mandelbrot set. But there are an infinity of other directions in which the 4-dimensional Julibrot can be sliced at this point. Does the rectangle exist in any of these odd slices? As today's image shows, it most certainly does exist in at least some of the odd slices. Today's scene is sliced very near the Oblate direction, and the rectangle, if anything, is even more spectacular. The appearance of origin symmetry in the image is deceiving. A close examination reveals subtle differences at the corners. But if the slice had been exactly in the Oblate direction, the symmetry would have been preserved. I rated the image at a 5, since there are only so many times the same fractal object can be shown and rated above average. I named the image "Once A Rectangle--", because no matter how the orientation is twisted, the rectangle is always hiding somewhere nearby. The calculation time of under 3 minutes on the P2000 would be around 12 minutes on the P200 unit. But why calculate when the finished image is posted for viewing on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Near perfect weather prevailed here at Fractal Central on Monday. Only a slight bit too much humidity kept it from being absolutely perfect. Of course, weather perfection is a subjective thing. With almost no rain for the past month, the local farmers certainly are not calling the weather perfect. The fractal cats spent the day being cats. I spent the day trying but not quite succeeding avoiding activity. The next FOTD will appear in 24 hours. Until then, endure.

FOTD 28-05-07 (Green Enough [5])
by Jim Muth 27 May '07

27 May '07

FOTD -- May 28, 2007 (Rating 5) Fractal visionaries and enthusiasts: Today's evaporated image lies in the fractal that results when 3 negative parts of Z^(-1.5) are combined with 0.5 negative part of Z^(-5.5) and (1/C) is added. This fractal consists of a north-south chain of 3 bays, surrounded by much interesting semi- chaos. Today's scene is found in a small area of this semi- chaos at the northern end of the chain of bays. I named the image "Green Enough" when I was impressed by the greenish spider arms that appear to be swirling about the central midget. This midget is partly camouflaged by the 'bof61' inside fill that was necessary to bring the entire evaporated scene to life. I thought for a few minutes before I rated the image at a perfectly average 5. I would have rated it higher, but I could find nothing in it that really is above present-day fractal average. The one-minute render time on the P2000 would be extended to five minutes on the P200. Both times are well within reason. The most reasonable way to see the image however is to visit the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and view it there. A warm and somewhat muggy day here at Fractal Central on Sunday was ideal for outdoor activity of all kinds. There was a slight scare in the afternoon when a thunder-shower passed close enough to the south to produce a cooling gust of wind, but the rain stayed well away. The fractal cats had their activity indoors, so the 86F 30C weather did not concern them. My day was busier than I would have liked, but not so busy that I had no time for fractals. The next fractal will appear in 24 hours. Until then, take care and when you search for the answer to the universe, be sure you know the question.

No show in Windows.

This is an old par, for which I used one of Albrecht Niekamp's Multifractals. It renders just fine in DOS Fractint, but in Fractint for Windows is a "no-show". Am I just asking too much of the Beta?
