FOTD 02-12-04 (Alfred E Big-Ears [4])
by Jim Muth 02 Dec '04

02 Dec '04

FOTD -- December 02, 2004 (Rating 4) Fractal visionaries and enthusiasts: Today's fractal was created by the 'sqr(1/fn)' formula, a rather harmless little formula with few grand aspirations. With no variable parameters and a choice of only one function, much of this function's exploration involves trying the different outside and inside options. To create today's image, I chose the 'atan' function, inside=bof61, and outside=atan. The result is a rather goofy picture that reminds me of a certain goofy comic character. So I named the image "Alfred E Big-Ears". The rating is only a 4, but with a render time of only 41 seconds on my ancient P200 machine, the image is worth a look. The smooth metallic texture of the pinkish head contrasts nicely with the rough grainy texture of the elephant-like ears, making the rating perhaps a bit conservative. And with such a short render time, the image has an absolute worth of 576. Mr. Big-Ears can be found on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> patiently waiting to be downloaded. The sun was warm enough during most of Wednesday here at Fractal Central, and the 57F 14C temperature was mild enough, but the wind blew at 50mph 80kph for most of the day, and the roaring in the trees made the cats far too skittish to enjoy the outdoors. They satisfied themselves instead with a treat of tuna in the evening. This morning is partly cloudy. The wind has abated, but it is colder. Time will tell how the dynamic duo makes out. The work is a bit heavy today, so I had best get busy. The next fractal will appear in 24 hours. Until then, take care, and watch your credulity.

Buddhabrot
by Gerald K. Dobiasovsky 02 Dec '04

02 Dec '04

This my try at the new "passes=o" option, coaxing Fractint *not* to plot all Mandelbrot orbits, but only those outside the set (aka the well-known Buddhabrot). The formula uses Hiram Berry's idea of a rectangular grid of starting points independent of the actual display window (however, the actual screen resolution is used to subdivide the rectangle into a grid - but there's an option to further subdivide those "pixels"). Another option allows to avoid plotting orbits below a given iteration threshold (that is, starting points too far away from the fractal's border). Warning, patience required ;-) On my ancient Pentium 233 MMX an 1024x768 image produced by this par took about 6 hours 40 minutes!

FOTD 12-11-04 (Infinite Passage [7])
by Jim Muth 02 Dec '04

02 Dec '04

FOTD -- November 12, 2004 (Rating 7) Fractal visionaries and enthusiasts: Today's fractal takes us to the mandphoenix formula, a formula that gave me quite a battle when I started working with it. The formula has three variations, which are chosen by setting the degree (the third parameter) to 0, 2, or -3. For today's image I set the degree to -3. I worked with the formula almost 1/2 hour, finding nothing but scenes that reminded me of uninteresting odd slices of the Julibrot. I was almost ready to give up and accept one of those inferior images, when I stumbled upon the area of order that appears in today's picture. Suspecting that I could make something of the scene, I began juggling the colors. Not too much happened. Then I tried the different inside fill options, and found that the 'fmod' fill works quite well. I left the outside at the default 'iter', and began rotating and changing the colors again. A few minutes later, today's image appeared, quite by accident. Only a small amount of color tweaking was needed to finish the job. The image reminds me of a long straight passage, with exotic light-poles illuminating the way. It might be the tunnel to the next world that is sometimes reported by those near death. Or it could be nothing more than a backdrop for a scene in some sci-fi film that has not yet been made. Whatever it is, the passage goes a very long way, which is the reason for the name "Infinite Passage". Unfortunately, the passage remains unchanged as it stretches to infinity. This makes for a rather boring trip, so I satisfied myself with a view down the passage from the place where it starts. The rating of a 7 might be a bit liberal, but I did put more than average time into it, and it has that quality that brings a second glance. (BTW, this is an all-important thing to design into advertisements, so I am constantly seeking it.) The render time of just under 2 minutes results in an overall worth of 374. Those who prefer not to render may see the infinite passage by downloading the completed GIF file from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> The passage might be infinite, but the download time will not. Warm sun and a temperature of 61F 16C on Thursday here at Fractal Central made the cats happy and me also . . . . but today is cold and rainy. I fear the duo will have a rough day. My day will be fair enough if I find a worthy fractal for tomorrow's FOTD. If not, then my day will be un-fair. Check tomorrow to see how things go.

Re: Fractint 20.04 DOS ver reproduces the posted WOW image correctly
by Vortex Swirling 01 Dec '04

Thanks Hal. Check my last post under the Can't reproduce WOW image thread (which should now be Can...). Once I got a setup where I could boot up to Dos and try it, it works ok in native Dos. I posted some pictures under different resolutions. Roger -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.289 / Virus Database: 265.4.4 - Release Date: 11/30/2004

FOTD 01-12-04 (Spider-Arches [8])
by Jim Muth 01 Dec '04

01 Dec '04

FOTD -- December 01, 2004 (Rating 8) Fractal visionaries and enthusiasts: Today's striking fractal takes us to the 'spider' formula. We are coming close to the end of the list, but, as today's image shows, the goodies are not yet quite exhausted. I did little exploring in today's formula. I did not need to, as the center of interest was obvious in the default image. The perturbed versions merely twist and distort the spidery arms that give this formula its name. The rating of an 8 is due almost entirely to the coloring. I could not resist the urge to turn the scene into another endless pathway to the infinite. The reason for the name Spider-Arches is obvious. The rating of a 6 may be a bit overdone, but I rather like the strong coloring. The arched pathway may be seen, but not traversed, by running the included parameter file, or by downloading the finished GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> The clouds increased as the day progressed here at Fractal Central on Tuesday, but the rain held off until after dark, which gave the fractal cat duo a pleasant afternoon in the holly thicket. The temperature of 52F 11C was a bit chilly, but they didn't seem to mind. When evening came, only a small treat was needed to keep them happy. This morning is starting with heavy rain and high wind -- two things the cats do not like. I fear they will not have another good day. My day will be within reason, which is all I could ask for. The next fractal is only 24 hours away. Until then, take care, and did fractals exist before the big bang?

Re: [Fractint] Can't reproduce WOW image
by Vortex Swirling 01 Dec '04

01 Dec '04

I connected and formatted an old disk to fat32, then copied Fractint onto it. Then I booted up under a Windows 98 startup disk and was able to access it in Dos mode. The effort paid off. I was able to generate the WOW par in three resolutions which I posted. I was able to set the parameter all the way up to 141. At 141 it generated a blank screen but at 140 it could generate an image. If I set it at 16 and tried different resolutions all the images were the same as this one only sharper or less sharp. http://rogerkaufman.mystarband.net/WOW.SF6.gif That is to say it didn't generate alternate images at different resolutions as it did running under XP. I suppose the different looking images could occur if the parameter said 16 but it was actually something different. So its a memory problem such that in XP there just isn't enough memory to allocate when the parameter is set to 100. At least not with any tweaking I did. http://rogerkaufman.mystarband.net/WOW_640x480.gif http://rogerkaufman.mystarband.net/WOW_800x600.gif http://rogerkaufman.mystarband.net/WOW_1280x1024.gif -- No virus found in this outgoing message.

FOTD 22-11-04 (Quantae [NA])
by Jim Muth 01 Dec '04

01 Dec '04

FOTD -- November 22, 2004 (Rating NA) Fractal visionaries and enthusiasts: Quantum mechanics has become quite trendy as of late. Those with only a layman's idea of what it is about (I am in that group) have given it almost a miraculous meaning. I doubt some way-out ideas such as the quantum world being the place where disembodied souls go after death, but one thing seems certain -- that in the quantum world that lies underneath the intuitive everyday world revealed by our senses, things are far different than they are up here. My own view is that a structure shares much of the nature of its building blocks, and therefore the objective world of material objects and energies, which is com- posed of quantum stuff, is not as real as it appears. This im- plies that, by comparison, the subjective world of thoughts and visions is not as unreal as it appears. My view is not scienti- fic -- it is not supposed to be. It is verging on mystical. I mention all this because I have named today's image "Quantae", which I have decided is the plural of 'quantum'. I gave it this name because today's marksmandel formula does nothing more than multiply the Mandelbrot set, and today's image is one that could have been found more simply and quickly with the mandel formula. To make things as interesting as possible, I set the extra para- meter to the integer 32767, which is as high as it can be set without the formula defaulting back to 1. The parent fractal appears as a simple blue ring. (This ring seems suspicious. It is most likely an artifact of the math routine.) Around the in- terior of the ring lie 32767 identical lobes, each one contain- ing all the detail of the Mandelbrot set. I chose to explore a lobe centered on the negative real axis. Since I found nothing new in my adventures, I could not give the image a rating. It will be forever unrated, a misplaced bit of a spurious Mandelbrot set that does not really exist. Fortu- nately, the unrated image renders in almost exactly one minute. With no rating, it has no absolute worth. The quantae may be seen by running the parameter file or by down- loading the completed GIF image from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Sunday remained cloudy here at Fractal Central, but with a temp- erature of 63F 17C it was mild enough for the dynamic duo to enjoy the afternoon in the holly thicket at the bottom of the yard. I checked their whereabouts every half hour or so, and no unusual activity was ever apparent, so I assume they had a peace- ful afternoon. Only a small treat was needed in the evening to bring their good day to a satisfying close. Today is starting cloudy again, but in contrast to Sunday, rain is predicted. We will see how the duo makes out. My work is light enough for me to finish early this afternoon, so it looks like a satisfying day for me also. Until tomorrow, when the next FOTD appears, take care, and watch your quantum number.
