FOTD 04-08-02 (Screw Propeller [5])

FOTD -- August 04, 2002 (Rating 5) Fractal visionaries and enthusiasts: After a day without power and a live wire sparking and sputtering on the ground in the alley beside Fractal central, the local electric utility has finally repaired the situation, and things are back to normal. (I wrote the above paragraph around 11am this morning, when I assumed things were under control. Unfortunately, the power went off again before I could post the FOTD, and just now, 10:15pm, has come back on for good . . . I hope.) With no time to search for an outstanding fractal, I had to settle on a run-of-the-mill high-iteration midget located in a remote valley of the Mandelbrot set. I named the image "Screw Propeller". I gave it this name because the elements around the midget remind me of a ship's propeller, and not as an insult to some imaginary fellow named 'propeller'. Since the scene is in the classic M-set, and the midget happens to be the first one I came to, I have rated the picture a perfectly average 5. The only really unusual feature of the image is the high maxiter of 100,000 and the logmap setting of over 13,000. Since its magnitude is still within the range of conventional math, the image renders in 10 minutes. The image will download from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> in even less time however. The fractal weather Saturday started with a violent thunder- storm with 80mph (130kph) winds, over 4 inches (10cm) of rain in one hour, hail and continuous lightning. Trees fell everywhere. The day then continued with heat, humidity and additional but less violent storms. The 95F 35C heat and thunder kept the fractal duo of cats confined to the indoors. The power failure that ensued when a tree across the alley fell on power lines kept me from fractalling and left me with no excuse to escape the task of cutting and collecting the fallen tree limbs that cluttered the front lawn. Today is just as hot, but at least no more storms are in sight. Until the next time on August 06, take care, and fractals may be the answer, but first one must know the question.

It was a live 4,500 volt power line sparking and smoking, not actually on the ground, but tangled in the tree which had pulled it down. I suppose the downed line was not grounded solidly enough to trip the breaker. But it was a curious sight as different parts of the fallen tree smoked and burst into flame as the current arced across the breaks in the wood. We first called the fire department, but when the company arrived they said they could do nothing about live wires. They notified the power company, which already had been notified six times. But since over 100,000 lost power in the storm, the power company was overwhelmed. It was 16 hours before the crew finally reached the scene, cut up the tree, restrung the wire and moved on to the next job. Just to keep this on topic, the lightning during the storm traced lovely fractal patterns in the sky. Jim (the enlightened) Muth

Due to another (no kidding) power failure at Fractal Central, the FOTD for August 4 will appear ASAP. (As Soon As Possible.) Jim (in the dark) Muth

Yeah, we believe you ! ;-) >>>http://mschreier.tripod.com/english/jam/pic/julia_band2d.png This can be also achieved with Fractint, by using the evolver feature. I don't have it installed right now, but I remember a post a while ago with the specific instructions to get a picture just like that one. Somebody in the list will probably find out the required evolver settings, in a matter of microseconds.

FOTD 02-08-02 (Twirling Banners [6])
by Jim Muth 02 Aug '02

02 Aug '02

FOTD -- August 02, 2002 (Rating 6) Fractal visionaries and enthusiasts: At first glance, today's image looks like an exotic midget created by the MandelbrotMix4 formula, but it is not. The image, with it's almost-disconnected appearance, is actually a scene in our faithful old friend, the Mandelbrot set. The scene is located deep on a filament in the northeast suburbs of the large midget on the negative stem of the M-set. The exact location can be found in a few seconds by outzooming. As one backs out, the magnitude soon falls within the range of conventional math, so the trip back to the surface is a fast one. Today's scene almost appears disconnected, but it is not. All parts of the Mandelbrot set, including the midgets and the elements around them, are connected to the main body of the set. The shoreline of every midget and the main body as well is a single unit. True, the connection is often made by an infinitesimally thin filament, but the connection is there. By comparison, many fractals created by the MandelbrotMix4 formula are not connected. In these fractals, there frequently is no main body, but only a cloud of fractal debris scattered around the area like ejecta around an explosion. And like at the scene of an explosion, isolated bits of debris are often found far from the center, totally disconnected from the rest of the fractal. I named today's definitely connected fractal "Twirling Banners" when I was reminded of synchronized gymnasts twirling their banners. If it were not part of the M-set, today's image might have rated a 7. As it is, a rating of a slightly-above-average 6 will have to suffice. Since the image is in the magnitude range where arbitrary precision math is required, it takes over 22 minutes to render on my P200 machine. A download of the completed GIF image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> will be considerably faster. The weather Thursday here at Fractal Central was of the typical high-summer variety -- a temperature of 97F 36C, blazing sun, high humidity, and light winds. In the evening, thunder clouds developed on the horizon, but never moved in. These conditions kept the fractal cats confined to the cool indoors through the afternoon. In the evening, when the sun sank low and they finally did venture outdoors, the local catbird began annoying them, apparently aware that their bird-catching days are nearly finished. And now it's Friday morning -- another hot day -- and I've got a pile of work to finish. It's time to reconfigure the fractal shoppe into a workroom and get busy. Until next FOTD on the 4th of August, take care, and fractals are too complex to be natural, yet they are not artifacts. So what are they?

Volumetric Fractals, Julia and Mandelbrot mysteries
by Marc Schreier 01 Aug '02

01 Aug '02

Dear Fractint users, Ever wanted to see fractals in 3D? Then use Fractint's built in stereo support. But there is an interesting alternative: volume rendering!!! A friend of mine is working with volumes in his PhD thesis and I did some nice datasets just for fun - and to explore fractals in a very different way. While my computer calculated lots of Julia sets I also discovered a surprising phenomena, but see yourself :) You are welcome to visit my latest work, the "Julia and Mandelbrot" page, at http://mschreier.tripod.com/ To my person: Actually I'm living in south of Germany, I'm working for a local car supplier compagny, and just got the MSc in Distributed Computing Systems Engineering at the Brunel University (Uxbridge, West London). I was exploring fractals since 20 years, first on the good old C64 (remember the Mandelbrot renderer that used also the 1541 floppy CPU?), then with Fractx86 and later with Fractint. I'm mostly interested in 3D graphics, surround sound and model railways. Best regards Marc --------------- JX-8P Resource Center http://www.synthzone.com/~mschreier/ ---------------
