. 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/>

. ""how many 3-D spheres could fit in a 4-D hypersphere of the same diameter?"" isnt that like saying how many 2-D circles could "fit" into a 3-D sphere of the same diameter? rotate the circles along the 3rd axis and the number is infinity (i think) .

FOTD 31-07-07 (The Parent Fractal [Not Rated])
by Jim Muth 30 Jul '07

30 Jul '07

FOTD -- July 31, 2007 (Not Rated) Fractal visionaries and enthusiasts: We end the month of July with one of those mysterious parent fractals I so often mention but so rarely show. But this parent is so unique that I just could not let it fade into the shadows of lost fractals. It is so unique in fact that I intend to use it as the source of the next few days' images. And yes, it is the parent of yesterday's 'Endless Loop' image. Even more surprising, I reused the color palette of yesterday's image. The formula that created this parent combines 2.5 parts of Z^(-1.05) with 0.35 part of Z^(-5.05) and adds (1/C). Since it is an image which came about with no exploring, I could not fairly give it a rating. The name I gave the image -- "The parent Fractal" -- is a simple description. The calculation time of 40 seconds is brief enough to make the most impatient fractalist happy. But the most convenient way to see the image is still to visit the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and view it there. One final note -- today's image is not the last we will see of this parent fractal. Hazy, hot and humid (86F 30C) was the weather story here at Fractal Central on Monday. Thunder-showers were in the general area most of the day, but none ever came close enough to cool things down. The fractal cats kept cool by ignoring the heat. I kept cool by being too busy to notice it. And the air condi- tioning helped keep me cool also. The next FOTD will appear in 24 hours. At least it is supposed to. Only time will tell if it actually appears. Until next time, take care, and how many 3-D spheres could fit in a 4-D hypersphere of the same diameter?

FOTD 29-07-07 (Not a Blank Screen [7])
by Jim Muth 30 Jul '07

30 Jul '07

FOTD -- July 29, 2007 (Rating 7) Fractal visionaries and enthusiasts: Before I begin today's discussion, I must warn that there is a bug in the parameter file. When the image is run directly from the parameter file, the imag(p3) parameter comes up as some ridiculous negative number, resulting in a blank screen. To see the correct image, the imag(p3) parameter must be re-entered by hand to the correct value of 3900000000 or 3.9e+009. When this is done, the image generates normally. I have no idea what the bug is. And my apologies for the late FOTD. Fractal lady and I decided to take the day off on Saturday to enjoy the countryside. We did so much enjoying that it was almost 11pm when we made it back exhausted to Fractal Central. For today's fractal we return to the MandAutoCritInZ formula, and check the fractal that results when various parts of Z^(-1.1) and Z^(-7.7) are mixed before (1/C) is added. The resulting parent fractal is a grossly oversized thing with a prominent 'fan' on the X-axis, with the handle facing west. Today's image is located in a bit of fractal decoration on the blade of this fan. The bailout in today's image is almost 4-thousand-million. I was working with different parameters when I noticed that the fan evaporates as the bailout is raised. This evaporation starts at the handle and proceeds toward the edge. I set today's bailout to the point where the area of today's image is just about ready to evaporate, and rendered the fractal with the inside set to 'bof61'. The resulting image is a cross between a conventional image and an evaporated one. I named the image "Not a Blank Screen" for the obvious reason. If you see a blank screen, you have not changed the imag(p3) parameter. Then I rated it at a 7, which is the minimum rating that I consider satisfactory. In comparison to yesterday's image, which takes nearly an eternity to finish, today's finishes in under one minute on the fast P2000 machine and about 5 minutes on the P200. The image is also available for viewing on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> but because of the unusual time of day, and the bug in the parameter file, it may be a few hours before it is posted there. So be patient. It was a bit too warm and muggy for perfection here at Fractal Central on Saturday, but the fractal cats didn't mind. When we returned late in the evening, we found Nicholas sleeping in the magazine rack and Cassie curled on the coffee table, both of them happy but hungry. Tomorrow's FOTD will be another good one, and it will appear in only 12 hours. Until then, take care, and save energy; shower with a fractal.

If a time travel method was developed and you did set out to do this, some how, some WAY your effort would (would have) failed. Because it has "already happened".

FOTD 30-07-07 (An Endless Loop [7])
by Jim Muth 29 Jul '07

29 Jul '07

FOTD -- July 30, 2007 (Rating 7) Fractal visionaries and enthusiasts: In today's image we mix various portions of Z^(-1.05) and Z^(-5.05), then add (1/C). The parent fractal created by this formula is a grossly oversized thing -- a Mandeloid festooned with decorative rings -- a fractal that cries out for further exploration. Today's image is located inside one of the rings. I named the image "An Endless Loop". The circular arcs must have inspired the name. Then I rated it at a 7, which is the rating where satisfaction begins. The calculation time of 7-1/2 minutes is within reason. Viewing the image on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> is also reasonable. Sunday was cloudy and humid here at Fractal Central, with a short but heavy thunder-shower in the afternoon. The temperature reached a high of 82F 26C right before the rain arrived. The fractal cats didn't mind the rain, but they were very annoyed when their supper was late. My day was slow and lazy, which explains the short discussion. My excuse is laziness. If I can shake this lazy spell, the next FOTD will appear on schedule, and it will be a good one. I'm going to do further exploration in the parent fractal of today's image. Until next time, take care, and if one went back in time and killed his earlier self, would he be guilty of homicide or suicide?
