Here are the config.sys and autoexec.bat files I use with my dedicated Fractint machine. I have also included the directory of all files on the DOS-6.22 boot disk, which on start-up takes the machine directly into the Fractint program, with 634,144 bytes of conventional memory free. The last line in the autoexec.bat file runs a file named fr.bat, which in turn runs fractint.exe. (It is simpler and faster to type <fr> than to type <fractint>.)

FOTD 16-11-02 (Curly Slices [4])
by Jim Muth 16 Nov '02

16 Nov '02

FOTD -- November 16, 2002 (Rating 4) Fractal visionaries and enthusiasts: Today's image is a scene in the fractal that results when 8 parts of Z^(-11) are added to 12 negative parts of Z^(-1.1) before adding 1/C. Normally, this parent fractal would be an island surrounded by an infinite ocean, but by adding 1/C instead of C the entire fractal has been turned inside out, or inverted, and instead of appearing as an island, the fractal resembles a marshy area with X-axis symmetry, which is filled with debris-choked ponds. Perhaps the most prominent feature of this parent fractal is the large fan-shaped feature just east of the origin. Similar fan- shaped features often appear in inverted fractals created with negative powers of Z. At first glance, these fractal fans appear to be totally non-critical and therefore devoid of midgets, but a careful search sometimes proves otherwise. Today's image lies in the outskirts of a larger midget in a cut-off feature in the northern part of its parent's fan. I gave it the name "Curly Slices" when I noticed the resemblance of the four prominent features surrounding the midget to slices of bread with curly extensions attached to their top corners. Maybe it is just my less-than-cheery mood, but I could find nothing in the image that would rate higher than the slightly- below-average rating of 4 that I gave it. The 13-minute render time can be avoided by downloading the completed GIF image from one of the FOTD web sites, which may be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The Friday weather here at Fractal Central was very pleasant, and the cats were very happy. Warm sun, light breezes, and a temperature of 63F 17C gave them a comfortable afternoon in the yard. But this morning is cold and rainy, and it will likely stay this way all day, and the dynamic, sun-loving cats will likely be far less satisfied. For me it will be a day to finish a small amount of work and watch the rain. When I tire of watching the rain, I will turn to the world of fractals. The best fractal I find will appear as tomorrow's FOTD. Until then, take care, and turn to fractals when reason fails.

FOTD 15-11-02 (Parabrot [7])
by Jim Muth 15 Nov '02

15 Nov '02

FOTD -- November 15, 2002 (Rating 7) Fractal visionaries and enthusiasts: I have named today's image "Parabrot" because in my opinion it lies just a little beyond the normal fractal scene. (Whether my opinion agrees with the opinions of others is another story.) The parent was found by the Fractint evolver feature, which IMO is one of the program's best features. The parent was created by combining portions of two different negative powers of Z, in this case, Z^(-1.6) and Z^(-3.6), then adding (1/C). This parent is an indescribable thing consisting of many bays filled with islands, with a large irregular ring extending to the east and north. Today's scene is located in a spiral at the southern origin of this ring, near the point where the ring vanishes into the center of a Mandeloid valley. The image itself is one of unusual smoothness, though this smoothness cannot be fully displayed with a palette of only 256 colors. The color bands are not arranged consecutively. The iteration count alternates back and forth in a curious manner, which might be natural or might be an artifact of the math routine. The rating of a 7 could be a bit overblown, but the image is at least a little above average. The render time of a little less than 15 minutes can be avoided by downloading the finished image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Thursday turned out to be very pleasant, with lots of sun and a temperature of 61F 16C. Accordingly, the cats were so pleased that they finished the day with a purr. And I finished the article in "Skeptical Inquirer" magazine. I found it to be rather routine, containing little new debunking material. Basically, it re-stated the obvious fact that before the existence of PSI can be assumed from experimental results, all the other things that might possibly have caused the small discrepancy from chance should be eliminated. Since it is impossible to totally eliminate all the other things that could possibly influence the outcome of such PSI experiments, the world-view of the 'hard skeptics' is still safe, and they will not need to admit the possibility of the existence of the paranormal. As for me, I am now forced to admit the existence of the work on the shelf, which must shortly be finished. It's time to get busy, so until next FOTD, take care, and be cautious with feral fractals.

FOTD 14-11-02 (Four Corners [7])
by Jim Muth 14 Nov '02

14 Nov '02

FOTD -- November 14, 2002 (Rating 7) Fractal visionaries and enthusiasts: Today's fractal is unusual in that it contains flat, nearly featureless areas surrounded by areas of total chaos. The flat areas are of more interest, since many hold midgets at their centers. Today's image shows one of these flat areas, with its midget sitting proudly at its center. To emphasize the difference between the chaotic and flat areas, I have given the scene a color palette that highlights the flat areas. The largest flat area, which surrounds the midget at the center, has four well-defined spirals at its corners, thus the name "Four Corners". The other obvious flat areas in the image appear to also have midgets at their centers, but I have not yet checked these. The parent fractal was created by combining some Z^(-2.1) with a lesser amount of Z^(-8.9), and adding (1/C). The exact portions were chosen at random with the program's evolver feature. The parent's shape resembles a clover-leaf, with no immediately apparent critical areas. But sometimes things can be critical where least expected, and today's parent is a fine example of this always-enjoyable phenomenon. A trip back up to the surface of the parent fractal will reveal how unlikely the existence of today's midget would seem to be when seen from the surface. And some other interesting things will be seen on the way, including a tiny, most unlikely bud, in the valley of which today's scene is located. Not wanting to under-rate myself, I rated today's image at an above-average 7. Yes, I realize that if every image is rated at a 6 or 7, then the standard for an average image will increase until the typical image once again rates a perfectly average 5. But that is a consideration for the future. The render time of 24 minutes is slow. The download of the completed GIF image file is fast. The download can be found at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather here at F.C. on Wednesday was cloudy, breezy and chilly, with light rain in the morning. The wet grass and temperature of 50F 10C kept the fractal cats pretty much house bound, but they accepted their confinement with only a modicum of displeasure. Today is starting sunny, and it is due to be warmer. The cats should have a better day. My day will improve when the work is finished and I have had time to settle down to read the latest issue of "Skeptical Inquirer" magazine, which I picked up last evening. In it I see an article which, at first glance, appears to state that psychokinesis (mind-over-matter) has been con- firmed by the rational scientific method that skeptics place so much faith in. The article then tries to escape the rational conclusion by stating that something must be wrong with the standard scientific method of doing statistics. I haven't read the entire article yet, but if it in fact claims what it appeared to claim when I skimmed it, I'll have much to philosophize and be cynical about in the near future. If the standard statistical method could lead to a wrong conclusion about psychokinesis, how many other currently accepted statisti- cal proofs could also be in error? On the other hand, if psycho- kinesis is true, how many other 'paranormal' things could also be true? Things could be getting interesting. (Or perhaps I got the wrong impression when I skimmed the article.) Until next time and next FOTD, take care, and though skeptics doubt the existence of a non-material world beyond the senses, why do they still fear that it might exist? (One thing for certain is that the non-material world of fractals does exist.)

xfractint questions and quirks
by Natalie 13 Nov '02

13 Nov '02

Hi, I've been playing with xfractint 20.2.04 for about a week. (I've used Fractint since version 8.) Here is a list of some (strange) things I've observed. (I *did* read the doc and the man-page. The BUGS-section in the man-page points to the README file for a list of bugs, the README file only says: You will almost certainly need to edit the directories at the top of the makefile! I downloaded the complete mailing-list archives, searched for anything related to xfractint, but didn't find an answer to these problems. I submitted the boundary trace bug to the Fractint Buglist (twice), but so far I teceived no response.) 1. ---------- passes=b does not work, it freezes up xfractint. Sometimes the 'freeze' occurs at the very start, sometimes it draws about three quarters of the fractal, but until now I haven't been able to finish a fractal in boundary tracing mode. All keypresses are useless, both in the fractal xterm-window and in the input/output xterm-window. The windows can be closed by <Alt-F4> or by using the mouse. I started xfractint again, zoomed in on the default mandel and changed passes to tesseral. No problems there. Saved the parameters. Changed passes to boundary tracing, xfractint froze (as expexted). Since I couldn't save the gif in xfractint, I made a screencapture in the Gimp, and saved the file as a gif. Copied the par to an old DOS-only machine. Restored the par in fractint (Version 2002 Patchlevel 4). Saved the parameters for comparison. Changed passes to boundary tracing, no problems, saved the par and saved the gif. I now have a par-file with three entries: - tesseral_linux - tesseral_dos - boundary_dos two giffiles - b_dos.gif (57622 bytes) - b_x.gif ( 8622 bytes) If anyone wants them I can mail them. 2. ---------- Why is the initial colormap different from the DOS-version? It has blues and greens, and white where the default.map has blue. I use xfractint map=default.map to get the old familiar default colors back. 3. ---------- In the DOS version I always had separate directories for par, frm, ifs, l, and map files. In xfractint I have to dump them all in the same dir or they won't be found. Is there no way to use multiple directories in xfractint? 4. ---------- In DOS I could move to another dir or to another drive, xfractint doesn't seem to know there are subdirs in the default dir. 5. ---------- Is it possible to create an xfractint.rc file (like sstools.ini)? I know I can add options on the command-line, but I don't think the command-line is long enough to hold a complete sstools.ini file. 6. ---------- When I use <Page-Up> to call up a zoombox it is not always visible. I tried <Ctrl-Ins> and <Ctrl-Del> to change the colors, no effect whatsoever. I tried <Ctrl-I> and <Ctrl-D> too, still no change of color. When using the mouse, the zoombox is visible. It makes no difference if I use the left or the right button. Manipulating the zoombox while using the mouse seems impossible. As soon as I release the button, the zoom-in is drawn. 7. ---------- Sound doesn't work always. Sometimes it beeps (through the speakers) when an image is completed, sometimes it stays silent. I tried the music pars. Message: Oops. I couldn't understand the argument hertz=220 Any key to continue. 8. ---------- In the Helpscreens: Backspace to get to the Last Topic dooesn't work. The Helpscreens get scrambled after moving from one link to another and after moving around with the cursor-keys. I captured the screen-output in a textfile and added a short description of what I did and what happened. Ths file is also mailable. (5642 bytes) Anyone? But... despite the bug(ette)s, quirks and oddities, I still DO love it! Thanks! Natalie -- Stolen tagline: Linux is like a wigwam, no windows, no gates, apache inside.

FOTD 13-11-02 (Scattered Fractals [6])
by Jim Muth 13 Nov '02

13 Nov '02

FOTD -- November 13, 2002 (Rating 6) Fractal visionaries and enthusiasts: With its dull, earthy brown shapes floating before a glowing, celestial blue background, today's fractal has a pronounced 3-D effect. It could be a glimpse of heaven as seen from one of the lower regions, presuming that heaven has blue skies, that is. But it is not. It is a fractal created by combining portions of Z^(-1.77) and Z^(-8.8). The ridiculous escape radius of 10^100 signals that the image is an evaporated one consisting entirely of trapped inside points. The picture consists of spirits of dead outside material made visible by a non-flat inside fill, in this case the < bof61 > fill. I believe this fill colors the inside points according to which iteration comes closest to the origin. I have named the image "Scattered Fractals". I gave it this name when I heard the phrase 'scattered showers' on the weather report on the F.C. radio. It is a true name because, as is the case with most all images, an infinity of smaller fractals is scattered throughout the scene. The rating of 6 might be a bit optimistic for an image with so many dark somber colors in the foreground, but the blue in the background speaks of better things beyond, and justifies the slightly above average rating. The render time of 6 minutes is a bit slow, but regardless of the render time, the completed GIF image can be downloaded in a minute or so from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> With the temperature at 50F 10C, the rain fell all day Tuesday here at Fractal Central, and the cats complained all afternoon, running from one door to another, searching futilely for the door that led to a sunny warm day. They never found the sun, and had to settle for treats of tuna and turkey. Today is starting cloudy and brisk. I've got cats to keep happy and work to finish. Until next time, take care, and enjoy your fractals while you have them.

FOTD 05-11-02 (Creepy-Crawlies [5])
by Jim Muth 13 Nov '02

13 Nov '02

FOTD -- November 05, 2002 (Rating 5) Fractal visionaries and enthusiasts: True, it's a few days past Halloween, but today's image has something creepy about it. With its somber dark blue color palette and its eight objects that could be taken as leeches, it might serve as an adequate cover for a paperback horror novel with a title such as "The Leeches that Sucked the World Dry". (Yes, I could be thinking of certain local politicians running for office. It's election day here in Fractal Central country.) Not wanting to name the image after something as unappealing as a dish of leeches, I gave it the more childish name "Creepy- Crawlies". The parent fractal is a grossly bloated Mandeloid rotated 180 degrees and on the verge of turning inside-out. The main period-2 bud, which is on the east side of the large bay has been totally obliterated by the ballooning bay itself. The bay has expanded so far that instead of the period-2 bud being the most prominent, buds with a periodicity around 30 or 40 are most prominent. Today's scene lies in the northern chaos that has accumulated as the whole fractal has expanded. I am sometimes asked how I find these midgets in unfamiliar areas of unfamiliar fractals. I'm not entirely sure how I do it. My attention is often attracted by elements that appear to have two-way symmetry. Then I simply get a feeling that a midget lies deep down at that spot, and when I go look, I am right as often as wrong. The route I took to today's midget can be retraced in reverse by turning off the logmap and outzooming. The trip back out will go faster if the passes is reset to <g> and thumbnail-sized images are calculated. Today's image, which was calculated in the basic default manner, with equal iteration bands on the outside and blank black on the inside, rates a 5. This is an average rating; the image is an average fractal. The 11-minute render time from the parameter file is somewhat excessive, but relief is always at hand at Paul's web site: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or at Scott's site: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> where the finished GIF image will soon be posted. The weather on Monday was uneventful here at Fractal Central. The partly cloudy skies, light winds, and temperature of 54F 12C made for a pleasant enough afternoon as the dynamic ones checked and explored the yard, finding nothing out of the ordinary in the process. It's now Tuesday morning and sun is once again illuminating the area. I've got a bit of work to accomplish before I can call it a day, so until tomorrow and the next FOTD, take care, and has anyone considered a fractal chess set?

twin graphics card problem
by Richard 12 Nov '02

12 Nov '02

Hi, I haven't posted much here, but I love the whole fractal thing since I found Fractint 19.1 on a CDROM. I have a problem, which I will detail below. I am running a desktop pc (duh) with a new Pentium 4 1.8ghz, with 2 graphics cards : the main is an NVidia Geforce 4 MX440 64mb, and the other is my aging Ati 3DCharger 2mb. What I would like to know is this : Can I run Fractint in DOS on my ATI Card's monitor at 800x600 fullscreen yet continue to run normal windows operations on my NVidia's monitor? If you need any more info, please ask, but I hope someone can help here. Richard. PS - How do you get the par files in a text format? --- Outgoing mail is certified Virus Free.

FOTD 12-11-02 (Solar Wind [7])
by Jim Muth 12 Nov '02

12 Nov '02

FOTD -- November 12, 2002 (Rating 7) Fractal visionaries and enthusiasts: In yesterday's fractal I colored the outside with the < real > option. In today's image I color the inside with the < epsiloncross > option. This option assigns colors to trapped points if they come within a certain 'proximity' distance of the X or Y axes. As far as I can remember, this is the first time I have used this option in an FOTD image. In today's image, the option creates the dark parabolic shapes in the foreground. The brilliantly colored arms consist of normal outside material. The parent fractal, which is created by combining portions of Z^(-1.85) and Z^(-5.5), was found with Fractint's evolver feature. It consists of an indescribable mass of various shaped bays surrounded by equally indescribable outside material. A ring of non-critical debris lies off the screen in the far distant southeast suburbs, but this ring does not figure in today's image, which is located in a valley at the tip of a filament extending from a bud in a small critical area at the northern end of the main body of bays. After studying today's image a few minutes, I was reminded of the solar corona. The name "Solar Wind" soon followed. The problem of rating the image was to decide between a 6 or a 7. In the end, I decided to flatter myself with a rating of 7. The render time of 11 minutes can be avoided by downloading the completed image from one of the FOTD web sites. Paul's site is at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Scott's site can be found at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Monday morning brought heavy thunder-storms to F.C., but the rain ended by noon, leading to a warm breezy afternoon that, by 3:30pm, dried the grass just enough for the dynamic duo to have a brief romp in the yard. The temperature of 70F 21C made up for any left-over dampness. This morning is once again starting rainy. It remains to be seen how well the fractal duo will handle the fresh dampness. As for me, I've got some work to handle. And the best way to handle the work is to do it. When the work is behind me, I'll start the search for tomorrow's fractal. Until next FOTD, take care, and bomb the enemy with fractals -- they are a lot less damaging.

FOTD 11-11-02 (Something_Fernny [8])
by Jim Muth 11 Nov '02

11 Nov '02

FOTD -- November 11, 2002 (Rating 8) Fractal visionaries and enthusiasts: State-of-the-art hi-tech is great, but it can also be quite annoying. One of its more annoying aspects is the constant need to 'upgrade'. Hardly a week passes where I fail to receive a file in a format that I cannot use. It is most annoying to try to load a file saved in super-publisher-36.2 format into version 36.1 of the same program and get nothing but an error message. Usually, a call to the customer only makes things worse, when I find that the document contains features that only version 36.2 can produce. Then I am faced with the choice of telling the customer that I cannot handle the document unless he makes changes, which he usually does not want to do, or spending several hundred dollars to 'upgrade' to the latest version of the super-publisher program. It must be a plot of the forces of evil -- most likely an invasion of off-world aliens set on bankrupting us so that we will be unable to resist the coming takeover. But I'm not concerned. We'll probably be better off once we have been taken over. ;-) Today's fractal is certainly not bankrupt. And I believe it is the first time I have colored an image with the outside coloring option set to < real >. This option does nothing but add the real part to the iteration count when a point escapes. But at least in today's case, it makes a surprising image. I named the picture "Something Fernny" when I had the impression of ferns growing on a forest floor. The iterated expression subtracts Z^(1.1) from Z^(-1.2) and adds (1/C). The resulting fractal consists of several large open areas, only one of which is an obvious Mandeloid. This Mandeloid is rotated -90 degrees so that its main bud points south and its East Valley lies on its north side. Today's scene is located in a small area of cut-off debris in the interior of this East Valley. I have rated the image at an 8. I was undecided on a 7 or an 8. Since the image appears somewhat different from my usual fare, and because of its 'illuminated from behind' effect, I finally decided on the rating of 8. The render time of under 2 minutes is surprisingly fast for the scene. The potential viewer may become an actual viewer by running the attached parameter file and enjoying the gradual appearance of the image, or by downloading the completed image from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and missing some of the enjoyment. The Sunday weather was quite mild here at F.C., but heavy clouds obscured the afternoon sun, and a few sprinkles of rain dampened the grass enough to make things a bit unpleasant for the fractal duo. Being courageous cats, they endured their displeasure stoically, taking their comfort in the temperature of 71F 22C. Today is starting cloudy again, and to make things worse, it is raining and there is a tornado watch in effect. I have a fresh supply of work that could keep me busy until nightfall if I don't get busy on it. Since I would like to be finished before nightfall, I had best get started. As for the cats, they will have to shift for themselves. Until next FOTD in 24 hours, take iterative care, and keep iterating.
