FOTD 18-10-04 (October 18, 2004 [5])
by Jim Muth 18 Oct '04

18 Oct '04

FOTD -- October 18, 2004 (Rating 5) Fractal visionaries and enthusiasts: The problem with today's image is that I could find no satisfactory name for it. Normally, I find the FOTD names almost automatically as I study the images (yes, this sometimes produces duplicate names). But after studying today's image for nearly 1/2 hour, and finding no satisfactory name for it, I finally decided to identify the image by giving it the name of the date on which it appears. (If I had done this with all the past FOTD images, I would have a far easier time identifying and finding them.) I used the 'fn+fn' formula built into Fractint to create today's image. Like the recent formulas that use the Fractint functions, this formula can draw a vast variety of fractals. Not all of the possible fractals this formula can create are useful however, but many are quite interesting. To create today's image, I chose to combine 0.4 imaginary part of cosxx(Z) with 0.4 imaginary part of sqr(Z). (The cosxx function is not a legitimate math function. It is a coding error that appeared in an early version of Fractint, but drew enough interesting fractals to make it worth keeping in the program when the error was corrected.) To add some extra life to today's image, I rendered it with the outside set to 'atan' and the inside set to 'bof61'. Surprisingly, the maxiter of the image, which is 95, has a great effect on its appearance. As the maxiter is increased, the foreground objects grow rapidly larger, until the greyish-blue background is soon filled in, resulting in a more detailed, but IMO less interesting image. (I am one of those who appreciates vast empty spaces.) Maybe if I had found a proper name for the image, I would have rated it at a 6. But the fruitless search soured me on it, and in the end, all I could give it was a rating of an average 5. The humdrum rating really surges to life however when the almost instant render time of 4 seconds is considered, resulting in an overall worth of a shocking 5822. The completed GIF image is or soon will be available on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> A sunny but rather chilly day here at Fractal central on Sunday made for rather cool cats. The duo prefers a temperature above the 57F 14C, which was as warm as it got on Sunday. They showed their displeasure by demanding (and getting) an extra serving of tuna. Today is starting just as cool. The cats might turn even cooler. Lckily, we have a lot of tuna in the cabinet. My next task is to find a cool fractal. Since the number of fractals is infinite, my chance of doing so must be 100 percent. But somehow, it just doesn't seem to work out that way. I'll be back here in 24 hours with a cool fractal. If I can't find a cool one, I'll have a hot one. Until then, take care, and don't lose your cool when you see a hot fractal.

I'm Back
by Dorothy Gibbs 18 Oct '04

18 Oct '04

Hi There, After a very long time during which I acquired a new computer, new email address (and two new knees! ) I thought I would see what the Fractint crowd were up to. Even in the first digest I received I see a couple of names I know..... great! I have a question.... I haven't tried it to see but my PC is now running XP pro (service pack2)... will I be able to run Fractint on it? Dorothy -- Dorothy Gibbs (in Hertfordshire UK)

FOTD 17-10-04 (The Blue Eagle Flies [6])
by Jim Muth 17 Oct '04

17 Oct '04

FOTD -- October 17, 2004 (Rating 6) Fractal visionaries and enthusiasts: Today's formula, fn*z+z, multiplies a portion of Z by one of the functions then adds an extra part of Z. The images thus created are many and varied. A bit bewildered by the possibilities, I took 0.56 part of acosh(z) and added 0.5 part of Z to it, creating a fractal with X-axis symmetry that vaguely resembles a snowflake. Today's scene, which is rotated 90 degrees from the normal orien- tation, is located on the X-axis. I named the image "The Blue Eagle Flies", though there is little in it that resembles a flying eagle. When I see the picture, I am reminded more of a levitating chicken than a flying eagle, but an eagle is a far more noble bird, so the name will remain. Whether the image shows a chicken or an eagle is not that impor- tant. The image has a certain 'feeling' about it that earns it a rating of 6. When the render time of just under 5 minutes is considered, the overall value scores a rather routine 122. The completed GIF image is available on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> The fractal cats did not enjoy the weather here at Fractal Central on Saturday. The temperature reached 64F 18C, and there was enough sun, but a severe thunder-storm arose in the afternoon, which dropped enough hail for the neighbors to build a small hailman (a snowman made of slushy hail). Another heavy storm moved in an hour later, which eliminated the hailman. The cats spent the better part of the afternoon in the closet, hiding from the noise of the thunder. Today promises to be much better, but after yesterday's deception, will the cats trust the sunny skies? I am placing my trust in the world of fractals, where I will find the next FOTD image within 12 hours from now. What I find will appear as tomorrow's FOTD. Until then, take care, and the end is nowhere in sight.

Fractint Question
by Michael Miller 16 Oct '04

16 Oct '04

Hello, I upgraded my system to an Asus a7n8x vm400 motherboard with sempron 2800 cpu 512 mb 3200 ddr 400 ram and nvidia geforce4 onboard video. This gives me more video options than I had before except that unless I use 320x200 16 colors I get "overrange" error where before with an 8mb agp 6356 video adaptor I could use up to 1280x1024 256 colors. Is there something I can do to be able to use the DOS version of Fractint at higher than 320x200 (prefereably 1024x768 256 + colors) ? Thanks, and my deep appreciation of your effots <s>. Sincerely Michael J. Miller Brio Follow the Son +

Just wondering if anyone's tried running DOS Fractint under Linux DOS Emulator (DOSEMU) or the BOCHS virtual x86 software? I'm moving to Linux, and XFractint isn't cooperating yet in basic ways (see other note about XFractint and SSTOOLS.INI). David gnome(a)hawaii.rr.com

FOTD 16-10-04 (Fractal Fossil [7])
by Jim Muth 16 Oct '04

16 Oct '04

FOTD -- October 16, 2004 (Rating 7) Fractal visionaries and enthusiasts: Today's image, which rates a 7, was created by the fn*fn formula. This formula doesn't bother with a constant term such as Z or C, it merely multiplies two functions and plugs the product back into the formula. When I brought up the formula, I expected little of interest to come from it, and indeed, for a while nothing did. But then I tried multiplying the cotan and cotanh functions, and activating the mainly blank screen with the bof61 inside fill. The result was a screen filled with chaos, but with little delicate and interesting objects of order scattered among the chaos. Today's image reveals one of these bits of order. It is not surprising that a formula that includes a hyperbolic function should draw a hyperbola. And that is exactly what we find at the center of the large semi-orderly area. Don't bother zooming into the center of this hyperbola -- I already did, and found that it's hyperbolae all the way down. The large central object in today's image reminds me of a fossil, so I named it "Fractal Fossil". The rating of a 7 might be a bit exaggerated, but the image really is a rather unusual one. When the 4-minute render time is figured in, the overall worth rates a respectable 173. The rendering may be avoided by downloading the completed GIF image from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> The heavy clouds and occasional rain hung around all day here at Fractal Central on Friday, holding the temperature to 64F 18C and keeping the dynamic duo of fractal cats confined to their lookout shelf by the side window, where, due to the rain, there was very little to look at. The duo took their disappointment rather well. Today is starting blustery and chilly, but only a few clouds are in the sky. It is too early to determine what the duo will make of it. For the fractal human, the work is caught up, leaving a day with not much to do but watch some games on TV and find a great fractal. The next FOTD will appear in 24 hours or I'll have a good alibi ready. Until next time, take care, and if nothing is real, is the knowledge of that fact real?

FOTD 15-10-04 (The All-Seeing Eye [8])
by Jim Muth 15 Oct '04

15 Oct '04

FOTD -- October 15, 2004 (Rating 8) Fractal visionaries and enthusiasts: Today's unusual fractal takes us to the fn(z*z) fractal formula, a formula that at first glance appears to have little to offer, but proves quite rewarding when explored. Like yesterday's formula, today's formula draws some images that consist mostly of blank 'inside' stuff that does not come to life until it is activated by a suitable non-flat rendering method. Today's image consists almost entirely of 'inside' stuff brought to life by the 'fmod' inside fill. Only the brilliant center 'sun' and the brilliant turquoise center dots surrounding it are made of 'outside' material. Quite surprising is the effect the 'fmod' inside fill has on today's image. This fill normally produces overlapping bubbles, but in today's image it creates virtually the entire fractal with its spider-like arms and smoothly gradated background. This is the best job I have yet seen the 'fmod' fill do on a fractal. I must one day check to see what additional surprises this fill has hidden in it. In the fn(z*z) formula the function is obviously a major part of the calculation. To generate today's image I chose the cotanh or hyperbolic cotangent function. When the bailout radius is set to 1, this function fills the screen with an unsurprising hyperbolic pattern. As the bailout radius is increased, the solid pattern breaks down into separate bits and pieces that grow smaller as the bailout is increased further, until they finally vanish entirely, leaving a blank black screen of 'inside' stuff. For today's image, I settled on a bailout of 1600, where the bits and pieces have grown quite small, but have not yet entirely vanished. When I am in scientific mode, I call such blank or nearly blank screens 'virtual fractals' because they resemble sub-atomic virtual particles that are caught halfway between existing and not existing, and need only some extra energy to bring them to full existence. In today's case, the 'fmod' inside fill supplies that energy. In mystical mode, I call such blank screens ghost images, because they resemble ghosts or spirits that really exist but are invisible to our everyday sight. In this case, the 'fmod' fill gives us the psychic sight needed to see the ghosts. Today's image resembles nothing as much as a great eye. I named it "The All-Seeing Eye" I leave it to the viewer to decide the owner of the all-seeing eye. With its rating of 8, today's image is the highest rated image yet of my tour through Fractint. The render time of under 2 minutes raises that rating to an overall worth of an impressive 430. As always, the minor job of image rendering may be avoided by downloading the completed GIF image from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> A nondescript day here at Fractal Central on Thursday left the fractal cats in an ambiguous mood. Variably cloudy skies and a temperature of 64F 18C, with light winds, were pleasant enough for humans, but the duo could not decide how they wanted to spend the afternoon. They finally divided their time between the porch and the holly thicket. The clouds are thick this morning, and rain is threatening, so I doubt that the cats will have a better day. For me, even if it rains, the day will be fair enough once the work is finished. And if all goes very well, I'll find a great fractal. Whatever happens, I'll return in 24 hours with the next FOTD. Until then, take care, and a great fractal is better than a flu shot.

Re: [Fractint] FOTD 13-10-04 (Circle Limit [6])
by Fr. Jim Lacasse 15 Oct '04

15 Oct '04

Jim, For artistic or esoteric beauty I'd make this closer to an 8. Jim LaCasse >>> jamth(a)mindspring.com 10/13/04 06:56AM >>> FOTD -- October 13, 2004 (Rating 6) Fractal visionaries and enthusiasts: Today's fractal is named "Circle-Limit". And why not? The formula that drew it is named 'escher_julia', and Escher drew several similar pictures which he named 'Circle Limit'. The 'escher_julia' formula draws circles filled with a variety of Julia-set parts. For today's image I chose a point near Seahorse Valley of the Mandelbrot set as the starting para- meters. These parameters only partly fill the circle with 'outside' features. Much of what appears inside the circle is 'inside' stuff. This presents no problem. I rendered the image with the inside set to 'bof61', which gives a nice shaded back- ground to the 'outside' features inside the circle. The image is a kind of graphic representation of a space of negative curvature, in which there is more space out there than would seem possible. In such a space, things appear smaller than their distance would indicate. If our universe has such a curvature, it will expand forever until it dies a slow death from increasing entropy. At least that is the old idea. But we are currently wrestling with all kinds of new forces and new ideas about the fate of the universe, and I'm not sure what its fate is now theorized to be. And even if we do determine its fate, how do we know that the universe will actually do what we theorize it must? It's all simply an interesting intellectual exercise. Today's image is a little above the average run of FOTD images, and earned an honest 6. Its speedy render time of 25 seconds results in an overall value of a huge 1395. The image may be viewed by booting the Fractint program and running the included parameter file, or by downloading the completed GIF file from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Tuesday was a bit chilly here at Fractal Central, but the sun was warm and the wind was light, permitting the fractal cats two pleasant midday hours of lounging on the porch, enjoying the sun. They took all the porch sun they could get. The sun is dropping lower, already skimming the tops of the holly trees even at midday, and in a week or so, the porch will be shaded all day. This morning I see clouds already moving in. With clouds and occasional rain expected for the rest of the week, the cats will likely be disappointed. With the today's fractal rating above average, I feel reasonably satisfied, but far better things should be possible, so I'll try again tomorrow on another formula. Until then, take care, and be careful not to bump into a fractal in the dark. Some of them have very jagged edges.
