FOTD 28-01-04 (The Quintessential Midget [8])
by Jim Muth 11 Feb '04

11 Feb '04

FOTD -- January 28, 2004 (Rating 8) Fractal visionaries and enthusiasts: Unless I am mistaken, today's FOTD is the third consecutive one that rates an 8. Combined with the render time of 19 minutes, its overall value is 41. This unexpected spate of excellence might have been equalled sometime in the past, but at the moment, I cannot recall when. But how did this excellence come about? Surely the extra time available for fractal exploration, due to the bad weather and resulting lack of work, is largely responsible. When I saw the golden ratio mentioned on the list, having nothing else to do, I was inspired to venture into the fractals that this mysterious number can produce. Turning to the MandelbrotMix4 formula, I checked the fractal that results when 0.8 parts of Z^(1.618) are subtracted from 0.8 parts of Z^(-1.618) and (1/C) is added. This fractal is an oversized thing consisting of three main Mandeloids, the largest of which barely appears in the southwest corner of the default screen. In today's scene I ignored this giant Mandeloid, which is mostly off the screen, and turned instead to the larger of the two Mandeloids that fit entirely onto the screen. This Mandeloid appears to be in what I call a condition of stress, as though it were ready to be cut off by a too-small escape radius. But stressed as it might be, the midget still has some interesting areas to check. The area I chose is the interior of the west branch of the valley leading to the large southern bud of this midget. Hidden there, deep in a cut-off area of interest, I found the midget that appears in today's image. And what a splendid midget it is. It is so splendid in fact that I named it "The Quintessential Midget", a title that is too long to fit into the allotted space in the parameter file. Actually, the midget looks as though it could use a few more iterations. This could easily be done, but if I raised the maxiter, it would mess up the color palette, which is what really makes the image. The render time of 19 minutes is a small price to pay for such a fine example of a midget. And there is even better news -- the completed GIF image is available for download on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Freezing drizzle prevailed all day Tuesday here at Fractal Central, making the area roads an ice-skating rink. The drizzle did not stop until it was replaced by heavy snow around sunset. With a temperature of 25F -4C, the day was a true winter wonder- land. Unfortunately, the fractal cats do not enjoy wonderlands, and passed the day indoors by the heat. I have lost track of the snow depth this morning. It appears to be around 1 foot in the U.S. measuring system, or 30cm in the rest of the world. Whatever the exact amount of snow, the dynamic duo will have another indoor day. For me, the work appears to have come to a halt, probably because everyone is snowed in. This means a good opportunity to find more great fractals. Any success I might have in Fractal Land will appear as tomorrow's FOTD. Until then, take care, and keep those fractals iterating.

The FOTD's are annotated quite nicely by Paul Lee with various web links. In the past there was a link to Paul Derbyshires "Quck Guide to the Mandelbrot Set" when describing various regions of the Mandelbrot set. The last known site where this guide posted seems to have gone 404. I been checking from time to time to see it might have found a new home. Then I found out about the Internet Wayback Machine at http://www.archive.org/web/web.php With it, you can find cached copies way back to 1996. A page might be cached several times. I was able to display the most recent cache of Paul Derbyshires Guide by going to this link.

FOTD 31-01-04 (Sevateem [7])
by Jim Muth 31 Jan '04

31 Jan '04

FOTD -- January 31, 2004 (Rating 7) Fractal visionaries and enthusiasts: I have no idea what the name of today's image has to do with its actual appearance. The name is one I invented on a whim, pure nonsense, a word such as one might find in the 'Alice in Wonderland' books. But such nonsense is not surprising in this modern-day world of science, where we have books of popularized quantum physics speaking nonsense such as Carroll never dreamed of when he wrote his 'Wonderland' books, and then declaring the nonsense to be a model of some strange kind of 'reality'. At least I make no claims that today's fractal is real -- not real in the every-day objective sense, that is. The image is a scene in the fractal that results when 1/3 part of Z^4.5 is added to Z^2.5 and 1/C is then added. This parent fractal appears as a fragment of a Mandeloid that fills the screen, with a sharply-defined but very distorted Mandeloid just off the bottom of the screen. In today's image, I ignored this distorted Mandeloid and concentrated on the large fragment. Today's scene is located at the edge of one of the arms marking the entrance to a partly-obscured bay on the southern edge of the fragment. As is frequently the case in fractals where two or more powers of Z are combined, certain parts of the image appear eroded, and filled with holes of all shapes. Today's image lies in such an area, and the greater part of it consists of such 'inside' holes. I have made this 'inside' area do things by rendering it with the 'fmod' option, with the proximity set to 0.25. The result is a FOTD that rates a 7 -- not as good as I might have hoped for, but certainly better than some of the images that have made it to FOTD status. Is the image worth the 11-minute render time that, combined with the rating of 7, results in an overall value of 63? This is a question which each individual must answer for himself. But the question may be eliminated by downloading the finished GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and avoiding the rendering stage entirely. Friday was a very busy day for me here at Fractal Central. For the fractal cats it was a boring day. The temperature of 23F -5C and brisk winds kept them confined to their beds by the heat. In the evening, they demanded a treat of tuna, which I gave them willingly. After all, I had ignored them all day. This morning is even colder. It looks like another day curled by the heat for the dynamic duo. For me it looks like a far slower day. If I'm clever enough, I might get through the whole day without doing a bit of useful work. And I'll return on schedule in 24 hours or so with another fractal. Until next time, take care, and be forever fractalish.

The colors changed when the maxiter was increased because the 'logmap' was used with the image. When the logmap is set to zero, the 256-color palette is repeated over and over, one color per iteration band, until the maxiter is reached. Increasing the maxiter produces no change in the colors that are already on the screen. It merely adds additional rounds of the palette to the new higher-iteration features. When the logmap feature is activated, the color palette is applied only once across the entire range of iterations. The individual bands are increasingly broadened as the iteration count increases. In this case, increasing the maxiter will broaden and therefore change some of the color bands already on the screen. Jim M.

FOTD 29-01-04 (Fractal Cesspool [4])
by Jim Muth 29 Jan '04

29 Jan '04

FOTD -- January 29, 2004 (Rating 4) Fractal visionaries and enthusiasts: Today's image is named "Fractal Cesspool". Yes, I realize that it is an unpleasant sounding name, but the experience of unpleas- antness is a natural part of existence in the physical world. Why should unpleasantness not be a part of the world of fractals? The image, which consists of squirmy bits and pieces, is not actually as unpleasant as the name implies. It is merely a part of the fractal that results when 1/2 part of Z^(1.5) is subtrac- ted from 5 parts of Z^(-0.5) and (1/C) is added. As is so often the case, the parent fractal consists of numerous disconnected Mandeloids. Today's scene is located in the chaos surrounding one of the largest irregular ones. The rating of a 4 is a big come-down from the recent run of 8's, but when the render time of 3-1/2 minutes is taken into consider- ation, the overall value is 115. The image can be viewed either by running the included parameter file or by downloading the finished GIF image from Paul's FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> As expected, the cold, ice, and high winds here at Fractal Central kept the fractal cats sulking indoors all day Wednesday. The temperature reached a high of 28F -2C, which is not unbear- ably cold, but the wind made it feel like Barrow, Alaska. The good news is that Fractal Central just missed being part of the big power failure that struck most of northeast Maryland on Wednesday when transmission lines swinging in the high wind came together and shorted out. That 250,000-volt arc must have been truly spectacular. So far today appears acceptable. The temperature promises to rise to freezing, the cats have not yet become active, the work is at a minimum, and the electricity is on. Hopefully, the day will remain acceptable. Until next time, take care, and be kind to orphan fractals.
