That still leaves the problem with the input screens. Having been writing medical software lately involving forms with a couple of hundred fields, I find myself resonating with this question! The problem I take it is that as the number of parameters bloats, so too does the number of lines required to display them in the screen. Four thoughts occur to me: Already, parameters are only listed in the screen if they actually appear in the code (if you only mention p1 and p3, then only p1 and p3 get listed). It's only sane to continue with this: if someone mentions (say) p12, p13, p14, p23, p24 and p34 (for representing rotations in 4-space) in their formula, then there is no point in the screen even trying to list thirty-four parameters. As I suggested, someone who asks for fifty parameters is asking for trouble, but some sort of scrolling may be the most graceful way of accommodating such stunts, rather than an ad hoc complaint from the parser (if it's the UI's problem, the parser shouldn't have to worry about it). At present, the parameters are listed like this: Real portion of p1 space for 20 digits. Imaginary portion of p1 0 Real portion of p2 0 Imaginary portion of p2 0 Real portion of p3 0 Imaginary portion of p3 0 But summat like: Real portion Imaginary portion p1 Space for 20 digits. Space for 20 digits. p2 0 0 p3 0 0 is only two characters wider, and almost halves the height. Tabbing between fields would zigzag from left to right down the list. It has the bonus advantage of more closely relating the real and imaginary parts of a complex number (and also groups the real parts and imaginary parts together for situations where only real parts are being used). The final thought is longer term: the text-mode UI will almost surely give way to a graphics-mode interface eventually, making much of this discussion moot by giving easy access to a more sophisticated interface widgetry (though I myself would insist on retaining the ability to simply hit to bring up the parameter dialogue, and typing numerical values for parameters).

Even with only p1 through p3 there were cases that didn't work. I ended up reworking the logic, so it should always work now. At least all my test cases worked.

Yes, that would work very well. It involves changing a routine used to display all the menus in Fractint. The changes will have to be done very carefully.

In honor of the damp occasion I produced a fractal that comes complete with dark billowing storm clouds and streaks of lightning. It should come as no surprise that in the midst of the turmoil lies the everpresent midget. The iterated formula that created today's stormy fractal is a close relative of the "Eutectic" formula of a week or so ago, though today I changed the second exponent of Z from -11 to -15 and changed the multiplication factor to -0.95. Though today's image was calculated by the MandelbrotMix4 formula, there may soon be a MandelbrotMix3 formula, which will take advantage of the additional parameter entries in the latest patch of Fractint. Yes, I realize that the sensible name for the next formula would be MandelbrotMix5, but I have never been one to do sensible things. With a running time of only a bit over one minute, the parameter file will recreate the image as fast as the GIF file can be downloaded from: or from: The fractal weather today was cloudy with moderate rain all afternoon, accompanied by thunder at times. The temperature of 75F (24C)was fair enough, but fractal cats don't like getting their paws wet, so they stayed indoors all day. The philosophy is coming, though it's not yet finished. Tomorrow may be the big day, so check then to see. Until next time, take care, and just because I say something doesn't make it true.

How close to the horizon is a graphic-mode windowing interface? Is it be worth the effort to do something fiddly if it will be trashed soon enough anyway? After all, the suggested layout would only stave off the problem of large numbers of parameters for a while, not solve it - and something that would (like a scrolling list) would be even harder to code.

Is it worth the effort to do something fiddly if it > will be trashed soon enough anyway? I wouldn't expect to see a graphic-mode windowing interface for a while (6-12 months). I am working on integrating the Allegro graphics package into the Xfractint source. This work is almost complete as far as the graphics modes is concerned. Once that is done, we need to port the code over to djgpp and/or a windows compatible compiler. The problem with making changes to the old source is that it takes time away from the new source. I do need a break occasionally, which is why I work on tracking down bugs that are reported.

They said there were over 3000 lightning strikes in the area this evening. At least 1000 must have been within a half kilometer of Fractal Central. Luckily, I had found my fractal before the power went off. The formula 10.45(Z^(-1.2))+0.95(Z^(-11))+(1/C) was iterated, and the bailout was raised to 10,100 to produce the fractal. The parent fractal is another variation of the parent fractal of the "Circle" image of a week or so ago. This image was once again created with the MandelbrotMix 4 formula. I'm working on MandelbrotMix3, which will begin producing FOTD fractals as soon as I get it right. I named the image "Hopi" because of the hoop around the tiny midget at the center, and also because the Hopis of the southwest USA supposedly have the ability to create rain by performing their rain dance. After seeing the deluge of rain this evening, I'm convinced that some Hopis must have been doing a rain dance in the vicinity. With a render time of 5 minutes, the parameter file is a bit slow. Relief may be found by downloading the fully rendered GIF image from the Usenet binary group: or from Paul Lee's web site at: The fractal weather today was very warm and muggy, with a light thunder-shower in the afternoon and a real whopper in the evening. The temperature of 93F (34C) was a bit too warm for the fractal cats, who remained inside, within a short dash of their hiding places when the storms came up. Sorry, philosophy-starved fans, the philosophy went nowhere again today. But keep checking -- one of these days you'll be pleasantly surprised. Until tomorrow, when philosophy or not, there will be a fractal, take care, and never give up hope.

Although the parameters appear quite a bit different from those of the past several days, the changes amount to no more than a simplification of the old parameters. The images the formulas draw remain unchanged. I named today's fractal "A Fractal for the Ages", not because it is so great that it will be remembered through the ages, but because I liked the sound of the phrase. The image is rather striking, with a kind of ceremonial effect that is hard to describe. In my current opinion it rates a 7; tomorrow or next month I may feel entirely different about it. The 5-minute draw time stretches the limits of reasonability. To make things more reasonable I have posted the GIF image to the Usenet group: and to the Web at: The fractal weather today was sunny with no rain for a change. But the fractal cats decided that the temperature of 95F (35C) was a bit too warm, and passed the day in the coolness of the air-conditioned Fractal Central. The philosophical ponderings, which have been so conspicuously absent lately, are once again absent today. But anything worth having is worth waiting for, so keep the faith and eventually the enlightenment will come. For now, I'm going to call it a night, close down Fractal Central, enlighten myself into the chair in front of the TV, and see how junky a show I can find. Until tomorrow, take care.

The reason was that I had saved the original and far better discussion and image on a floppy disk, to transfer the files from the Fractal Central branch office to Fractal Central itself. Somehow I lost the disk during the transport, which made me very angry. So I whipped out a new image in a few minutes, wrote a few words, and found that my Mindspring ISP was down. But all that was yesterday. This is today, and after yesterday's pathetic offering, we once again crank it up with a fractal that IMO rates an 8. The formula responsible for today's image is -1Z^(-11)-11Z^(-1.1)+(1/C), a formula that draws a parent fractal that must be seen to be believed. The parent is so unusual in fact that I might devote the entire month of September to exploring it. I named today's picture "Homespun Midget" because that phrase came to mind while I was studying the image for a fitting name. Actually, I would rather simply give my fractals numbers than attach names to them. But names do add a certain individuality to a picture, and occasionally I actually surprise myself with the poetry in a few of the FOTD names. The parameter file of today's image takes 10 minutes to render on a 200mhz Pentium, 5 minutes or less on the fastest machines. The GIF file downloads in less than two minutes. The choice of which route to take to the image is up to the potential viewer. The GIF image is available on Usenet at: and on the Web at: The fractal weather today was mostly sunny. Surprisingly, no rain fell. The temperature of 87F (30.5C) was just right for the cats. Tippy even chased a squirrel, which scampered up a tree and scolded furiously. Disappointingly, I have no fractal philosophy today. In fact, I have no philosophy of any kind. I have plenty to write about, but I just can't seem to get started. It must be a case of writer's block. Perhaps I'll get unblocked tomorrow, perhaps not. Check then to see. And even if you find no philosophy, the fractal will arrive on schedule and be worth viewing. Until then, take care, and see you soon.
