Re: [Fractint] Diode

Brings back memories - I'm an electronix tinkerer from way back, nothing recent though, just computers etc. "" Why attempt this ; because a better , more interesting insight might be obtained . Has anyone on this list delved into this ?"" If anyone can code the diode equation into something the fractint formula parser can understand, and make a "diode" fractal, and it loox cool enuf, I will try to animate it. It seems that many natural phenomenon, (like chemistry, my profession), can be modelled to some extent with fractals, often leading to interesting and unexpected results. stay amazed!

FOTD 01-05-09 (Yhrow-Away [3i])
by Jim Muth 30 Apr '09

30 Apr '09

FOTD -- May 01, 2009 (Rating 3i) Fractal visionaries and enthusiasts: I actually avoided getting dragged into a futile discussion on Thursday when FL uttered something about fighting climate change and I kept my opinion to myself. Finding a proper fractal was a more immediate if not quite as important task. Today's fractal image rates an imaginary 3. I have no idea how this rating fits into the usual rating scale, it must be off to the side somewhere, but after all the trouble the image gave me, I had to give it this rating. The clam-shell effect helped none at all. The problem was in the coloring. The scene looked promising when I found it, but nothing I tried produced colors that worked. I ended up rendering the scene with the outside set to 'summ', but even then the colors never approached anything near satisfactory. In frustration, I finally settled on today's too-blue-and-too- red color palette that is not helped by adding green. The name "Throw Away" refers to how I felt about the image when all my efforts at coloring failed. The calculation is thankfully fast, almost as fast as viewing the image, already calculated, on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Spring doesn't seem able to make up its mind. The temperature of 59F 15C and thick clouds kept the fractal cats close to the heat, which came on again here at Fractal Central on Thursday. My day was unusually busy. If it doesn't get even busier, the next FOTD will be posted in 24 hours. Until then, take care, and for those concerned, my opinion about climate change is that it is 50-percent politics, 49-percent commercial advertising and 1-percent real, and of this 1-percent-real part only 1-percent is man-made. To make matters worse, there is little we are able and truly willing to do about the 1/100 of 1-percent that is both real and man-made. But if it makes us feel good to imagine that we are actually doing something about climate change when we buy the products of the 'green' companies, all the better for both us and the companies.

FOTD 30-04-09 (In the Rectangle [6.5])
by Jim Muth 29 Apr '09

29 Apr '09

FOTD -- April 30, 2009 (Rating 6.5) Fractal visionaries and enthusiasts: I must have seen the mysterious Z^(2.003) rectangle over 100 times in my 20 or so years of fractal adventures, yet I have never gone very deep into it. Well, today we correct that oversight. Today's image lies deep within the same view of the rectangle that appeared in yesterday's image. Today's image shows a curious little thing, kind of like an alien being with a head on both ends, waving his arms, with smaller arms on his arms. BTW and not surprisingly, more mysterious rectangles lie where the smaller arms branch from the larger arms. I named the image "In the Rectangle". That's where it is. Then I rated it at a 6.5, which is adequate and reflects a 1/2-point bonus for coloring. The calculation time of 2-1/2 minutes means no one will be annoyed because they spent too much time calculat- ing a disappoining image. Of course, the easiest way, as always, to see the completed image is to view it in its full glory on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Hazy sun and a temperature of 70F 20C made for a pleasant day here at Fractal Central on Wednesday. The fractal cats, who on Tuesday had complained about the heat, complained instead about the lack of food in their dishes. I complained about the health- care job, which the customer is still making changes on and which he insists we deliver by Friday. FL complained about my cavalier attitude toward life and death. She said that some- times I 'upset' her when I talk about stuff like that. The next FOTD will be posted in 24 hours. Until then, take care, and how can it be bad news to talk about going to eternal happiness? (Then again, maybe we're not quite so certain that it's actually there.)

FOTD 29-04-09 (Mystical Rectangle [?])
by Jim Muth 28 Apr '09

28 Apr '09

FOTD -- April 29, 2009 (Rating ?) Fractal visionaries and enthusiasts: Tuesday was interesting here at Fractal Central. FL and I were at breakfast with the TV playing softly in the background, when FL suddenly asked, "are we going to die?" Without much thought, I answered, "Of course," and FL exclaimed something like 'oh my God!' I was reading the paper, and did not realize that the quarter-hourly swine-flu scare was being hyped on the TV morning news show and she was referring to the flu scare. When I realized what she was talking about, I assured her that the whole doomsday atmosphere was created to get people to worry so that they would spend more time watching the news channels and thereby enable the stations to charge more for their adver- tising. But the whole thing really started my philosophical juices flowing. I love mysteries, and next to the fourth dimen- sion, death must be the biggest mystery of all, so expect some morbid musings in the not too distant future. A more immediate concern is how to rate today's fractal. After at least 2 minutes of contemplation, I realized that I would never be able to honestly rate the latest appearance of my old friend, the rectangle in the Z^(2.003) Julibrot, so I rated it as a question mark. The name "Mystical Rectangle" refers to the mystery of trying to determine the true four-dimensional shape of the object that is rectangular in only two of its four dimensions. Today's orientation is very close to the Julia direction, just far enough removed to make the scene interesting. I'm not sure what slices the JulibrotZpwr formula cuts in Julibrot, but I have never found similar slices with any of the other four-dimen- sional formulas. The calculation time of 1-1/4 minutes is very fast. Equally fast is the trip to view the finished image on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> The April heat wave continued here at Fractal Central on Tues- day. The fractal cats made the most of things by avoiding the hot sun and temperature of 90F 32C. The humidity remained low however, so the cats were reasonably happy. My day started slow, but turned busy when an unexpected job arrived around 10am. Crises notwithstanding, the next FOTD fractal will be posted in 24 hours. Until then, take care, and why worry about the flu, when the disease that will kill everyone is already out there. It is not yet fully defined, but it is 100-percent fatal and everyone is certain to contract it and die of it. Its name is 'something'. (Don't blame me for mentioning the unpleasant and inescapable truth! I didn't make things this way. The Big Guy up in the sky did it, so blame Him.)

FOTD 28-04-09 (Stripes in Sight [4.5])
by Jim Muth 27 Apr '09

27 Apr '09

FOTD -- April 28, 2009 (Rating 4.5) Fractal visionaries and enthusiasts: Even with its half-point bonus for the coloring, today's image is nothing to write home about. The parent fractal resembles a Julia set with a grossly enlarged Mandelbrot bud in the back- ground. In the southeast corner of the parent lies a prominent spiral. Today's image shows that spiral with stripes added, plus one of the smaller but much-enlarged Mandelbrot ghost buds lurking in the background. I posted the image after trying for almost an hour to bring it to life, with very little success. I named the image "Stripes in Sight". One look at the image will explain the name. I have done many images of this type over the years, and most of them are notably better than today's. The maxiter of 32,767 is barely adequate for the ghost-bud effect. A maxiter of some- thing like 200,000 would improve the definition, but it would also almost double the calculation time. Oh, what the heck. I think I'll go ahead and raise the maxiter to 200,000. The calculation time has now been raised from 10 minutes to just under 17 minutes, which is far too slow for an image of such questionable quality. I strongly recommend sufing to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the finished image there. Too much of a good thing prevailed here at Fractal Central on Monday. The temperature of 93F 34C combined with an unbroken hot sun made for heat that sent the fractal cats searching for the coolest place they could find. With the cool air vents in the living room not yet producing cool air, the cats chose to lie on the cool tile of the bathroom floor. My day was very close to average. Most likely, tomorrow will be the same. The next FOTD, a much-improved one without doubt, will be posted in 24 hours. Until then, take care, and be at peace with your iterations.

. PNL say: ""WOW !!! Is that running a PC 24x7, or just part of a week?? And when did you start the project?? I assume it will be a really lengthy video (or maybe a full-length movie)."" The "universe #6" posted on my site goes to E+87. It was originally targeted to a minibrot at E+112 but I gave up on it at first cause I thought it impractical. However, after purchasing 2 new P3-933 systems to add to my render farm, and recalculating the sequence, it looks like it can be done by years end. The images so far look astounding - it is interesting how things keep getting more intricate and complicated the deeper in you go, nevertheless they still "look the same" due to self-similarity. It will be a full 6 minutes long. Patience ...patience.... If fractaleers have nothing else it has to be patience ....... .

FOTD 27-04-09 (Half Asleep [6])
by Jim Muth 26 Apr '09

26 Apr '09

FOTD -- April 27, 2009 (Rating 6) Fractal visionaries and enthusiasts: The Saturday trip to Old Fractal Central, where Thomas, the one remaining old fractal cat still lives, went well enough, but I didn't get back to new F.C. until almost midnight, and this is my excuse for having a very lazy day on Sunday. Today's image, which I found effortlessly with the Fractint evolver feature, is another of those MandNewt things that are a total puzzle to me. But whatever the image is, it rates a 6, and is relatively easy on the eye. A large part of the image consists of 'inside' stuff brought to life by the 'bof60' inside fill. Some interesting scenes might lie deeper inside the image, but I was too lazy to check. The name "Half Asleep" refers not only to the appearance of the fractal but to the awareness level of the fractalist as well. The calculation time of 3-1/4 minutes will bring joy to the hearts of every fractal fan, as will a trip to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> where the finished image is posted for immediate viewing followed by absolute bliss. The bright sun on Sunday here at Fractal Central looked promis- ing at first, but when the air temperature reached 91F 33C, the sun no longer brought comfort. The fractal cats tried lying in the sun for a couple minutes, then stretched beneath the cool air vent. Needless to say, April is too early to turn on the cool air, so the cats complained and cooled down on their own. After the trip to Old Fractal Central on Saturday, I spent Sunday doing little or nothing. FL spent the day working in her garden, while I checked her progress every hour or so to give the impression I would be ready to help . . . if she needed it. Luckily, she never did. The next FOTD will be posted in 24 hours. Until then, take care, and I just saw a Higgs particle fly past the window. And it stopped long enough to look in. I guess this makes me world famous.
