I have managed to compile and run fractint using Borland C 3.1 IDE My problem is that I cannot step through the code. When I try to 'step into' I get a popup message saying: ' WARNING: no debug info. Run anyway ? ' If you select Yes it just runs the whole program. Thanks, Newman

FOTD 30-08-02 (Curlers [7])
by Jim Muth 31 Aug '02

31 Aug '02

FOTD -- August 30, 2002 (Rating 7) Fractal visionaries and enthusiasts: Checking my e-mail box this morning, I found 23 messages, 18 of which were junk. I am not particularly annoyed by this junk mail, some of it is actually fun, especially those blatantly scam letters from the families of assassinated leaders I have never heard of in some unlikely African nations, who want to give me 8-million U.S. dollars if I send them my bank account number. And there is also the "very excite game" family of junk, which I have received hundreds of times, and delete immediately because they contains a virus. I simply delete most of this junk automatically. This morning however, when it took 20 minutes to download my queue of e-mail, I realized that things might be getting a bit out of control. I'm even getting undeliverable messages returned to me that I never sent. If the present trend continues, I might need to change my e-mail address in the not-too-distant future. But for the present, I'll stick with the 6-year-old 'jamth' address. Today's image existed for all eternity before I stumbled upon it yesterday afternoon. It is a scene in the fractal that results when 0.1 part of Z^12 is subtracted from Z^1.2 and 1/C is added. The fractal consists of a two-lobed Mandeloid with its main filament curling off to the east. The curl in this filament inspired the name "Curlers". Today's FOTD pictures a point far out on this curling filament, where a tiny midget lurks. Most of the impact comes from the coloring, on which I spent a few extra minutes. Thanks to the strong colors, the image, which otherwise would have rated a 6, rates a 7. The parameter file is unusually fast, running in the one-minute range on most machines. It will probably take longer to go online and download the completed GIF image file. But for those who will enjoy the trip, the completed image may be found online at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Thursday here at Fractal Central was of the fractal variety, as most everything in nature is, including the fractal cats, who endured 2 outdoor hours of heavy clouds and a tempera- ture of 70F 21C before surrendering to their need for food and coming in from the yard. As for me, I'd best get busy doing the things that need to be done here in the fractal shoppe. And that means work. So until the next FOTD three days from now on Sept 2, take care, and be of sound mind and nominally unsound fractals.

FOTD 28-08-02 (A Thorny Issue [8])
by Jim Muth 30 Aug '02

30 Aug '02

FOTD -- August 28, 2002 (Rating 8) Fractal visionaries and enthusiasts: The parent fractal of today's image is closely related to the parent of the image of Aug 26th. Negative portions of Z^(-2) and Z^(-3) are combined before (1/C) is added. The resulting fractal consists of a large central bay with a non-critical cloverleaf-like island at the center. This cloverleaf holds little of interest, but the western shore of the bay features a very prominent sub-bay, with critical buds and filaments. The filaments are not the simple jagged lines of the M-set filaments, but are twisted into loops and rings that hold countless midgets. Today's midget lies in a branch of a tiny ring near the tip of a filament. Actually, the midget is not there at all, for the escape radius of a full googol has totally evaporated the outside material, leaving only a blank inside of trapped points. But all is not lost. The inside fill of bof61 has revealed the ghost of the midget that once was there but now has gone. Curiously, the bof61 inside fill is the only fill that produces such a fine image. I think the bof61 fill colors the inside points according to which iteration comes closest to the origin, but I'm not sure. Regardless, the image rates an exceptional 8, which is the highest rating in several months. The name I gave to the image, "A Thorny Issue", is totally whimsical. The phrase simply came into my head as I studied the scene. (I'll bet a psych-something or other could learn a lot about my secret unconscious life from the titles I sometimes half-consciously give to my FOTD's.) The 3-minute render time of the parameter file is fair enough. A download of the finished image is even fairer. The completed image may be found on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and on Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather here at Fractal Central on Tuesday featured morning sunshine followed by increasingly thick afternoon clouds and a high temperature of 86F 30C. The duo of fractal cats must have approved, for they spent several hours prowling in the holly thicket at the bottom of the back yard, cleverly avoiding the burdock burrs and thistles that, despite all attempts at eradication, still grow there. And if I'm to avoid a late start in the morning, I must soon shut down the fractal shoppe and call it a night. Until the next mind-boggling FOTD appears on Friday the 30th, take care, and be as happy as the fractal duo.

Is that what you meant? To begin, I mentioned no program and no author, though the program to which I was referring was obvious, and I did comment that the program in question was a fine program. I did not state that the Fractint code had been stolen, though I did comment that some of it it might have supplied ideas, and in that way, have appeared in modified form in the other program. Finally, by my 'I'm an artist' comment, I implied that IMO it takes more than knowing how to use a computer program to be considered an artist. The word 'artist' implies creativity and originality. It does not imply doing the same things that the rest of the crowd is doing. Such people are better considered skilled craftsmen, which is what I consider myself. If you find this derogatory, I'm sorry. Jim M.

FOTD 26-08-02 (The Web of Terror [7])
by Jim Muth 26 Aug '02

26 Aug '02

FOTD -- August 26, 2002 (Rating 7) Fractal visionaries and enthusiasts: The midget at the center of today's image is located on the X-axis of its parent fractal, which has X-axis symmetry. This is demonstrated not only by the coordinates in the parameter file but by the straightness of the arms radiating from the midget. The 180 degree rotation of the image does not change the east-west orientation of the X-axis, so why do 2 out-zooms reveal a north-south oriented axis? The mystery is not very deep, a few more out-zooms reveal the true situation -- the X-axis is not continuous. Actually, only one out-zoom reveals an interesting scene -- a near-perfect array of square figures that almost made it as FOTD. The choice between the squares in the out-zoom and the octagons in today's image was a toss-up. The squares lost only because one of the two images had to lose. The generating formula subtracts 0.2 part of Z^(-3) from Z^(-2) before adding 1/C. If I had added the 0.2 part of Z^(-3) rather than subtract it, the resulting parent fractal would still have had X-axis symmetry, but its overall shape would have been totally different, and of course, today's image would not have existed. (More accurately, it still would have existed but it would never have been found.) I used the MandelbrotMix2 formula to find today's image. This formula works the same as the overworked MandelbrotMix4 formula, except that it includes the capability to change the starting point of Z. This capability is not used in today's image. The name of the image, "The Web of Terror", which sounds like the title of a horror movie, has no connection whatever to the appearance. I might have had a fleeting impression of a spider's web, but if so, I can no longer see the resemblance. The rating of 7 seems fairly accurate, and those who spend the 3 minutes to run the parameter file will not be disappointed. Those who download 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 not be disappointed either. The Sunday weather here at Fractal Central was perfect for most anything, with blue skies, puffy white clouds, gentle breezes, low humidity, and a temperature of 86F 30C. The fractal duo were happy all day, which is a rare event for them. My happiness however depends on finishing the work I now find before me. If I start now, I can be finished by 3pm. If I wait an hour, I will not finish before 4pm. If I put off some of the work until tomorrow, I can be finished by noon. Most likely, I'll choose the first option. Until next FOTD, which will arrive in all its glory within 48 hours, take care, and beware of fractals lurking in dark corners.

FOTD 22-08-02 (Square in Sight [7])
by Jim Muth 25 Aug '02

25 Aug '02

FOTD -- August 22, 2002 (Rating 7) Fractal visionaries and enthusiasts: Checking the fractal gossip lines, I see that a new version of the fractal generating program preferred by the trendy fractal crowd has just been released. I already have the previous version of the program, though I rarely use it, so I may or may not eventually pick up this newest version, for which the program's author is charging a nominal upgrade fee. In any case, I'll wait until a debugged version appears. I have nothing against the performance of this other program, it's a fine fractal generator, but I remember several years ago, when the Fractint list was receiving queries from the author of the other program, asking questions about the operation of the Fractint code. Shortly thereafter, the other program appeared on the scene as a shareware product, and the 'I'm an artist' crowd left the Fractint list to flock to the other program. So far, so good, but I wonder how much of the original Fractint code now resides in slightly modified form in the other program, which is being sold for profit. Something not quite ethical appears to have happened somewhere along the line, but neither I nor apparently anyone else can pin it down. Well, I guess it's time to move on from ethics to today's fractal, which was generated by the old-fashioned Fractint program aided by the MandelbrotMix4 formula. The expression 6Z^(-0.7)-0.12Z^(2.2)+(1/C) was iterated to create the parent fractal, which consists of a large double-lobed Mandeloid with a smaller satellite Mandeloid just to the east. Today's midget lies deep in the main valley on the east side of the large Mandeloid. I named today's image "Square in Sight". No square features actually exist in the image, but the coloring gives the appearance that the midget lies in the center of a square. This illusory square inspired the name. I feel that the rating of 7 is justified in light of the fact that the pattern around the midget is different enough to warrant notice. The render time in the 4-minute range is short enough to make running the parameter file practical and long enough to make it interesting. As always, those who would rather avoid parameter files may download the completed image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather was typical mid-summer fare here at Fractal Central on Wednesday. The high temperature of 88F 31C was just about average; the moderately high humidity and stagnant air were also average for mid-summer. The fractal cat duo had an average day -- one hour outdoors lounging in the shade, 22-3/4 hours indoors lounging on the floor, 1/4 hour eating. With another day's work before me, I'd best get busy without delay. Until the next glorious FOTD appears on August 24, take care, and remain steadfast.

FOTD 24-08-02 (Sliced Melons [7])
by Jim Muth 24 Aug '02

24 Aug '02

FOTD -- August 24, 2002 (Rating 7) Fractal visionaries and enthusiasts: Today's image is named "Sliced Melons". If the first three letters of the second word are reversed, the title becomes "Sliced Lemons". But there is nothing sour about the image, which uses the < tdis > outside coloring option. In fact, after careful consideration, I rated the image at a 7. The parent fractal combines portions of Z^2 and Z^3. The whole- number exponents result in a fractal that has no branch-cut discontinuities when calculated with the outside set to display the standard equal-iteration bands, but the < tdis > outside- coloring algorithm used in today's image introduces the disconti- nuities that are visible in the image. The parent fractal is a distorted Mandelbrot set rotated 180 degrees, with lots of interesting activity on its negative (in this case, positive) stem. East (in this case, West) valley of the parent fractal is also decorated with interesting spurious activity, though I did not explore this area. With a render time of 6 minutes on my humble fractal machine, today's fractal is a bit slow, making a download of the completed image the marginally better choice. The download is available on the W.W.W. at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Friday here at Fractal Central was overcast and very humid -- wet enough to swim in. The temperature of 86F 30C was about average. A few drops of rain fell in the after- noon, which is too bad, since we're in a rather severe drought. The fractal cats finished their outdoor activity before the raindrops appeared, so, unlike the local farmers, they were not displeased. With thunder-showers prowling the area this morning (Saturday), and some real rain hopefully soon to occur, I'd best wrap up this edition of the FOTD and see whether I can console the dynamic duo. Until next FOTD on Monday the 26th, take care, and be serendipitous.

Re: [Fractint] FOTD 22-08-02 (Square in Sight [7])

Hi Jim, >So far, so good, but I wonder how much of the original Fractint >code now resides in slightly modified form in the other program, >which is being sold for profit. Something not quite ethical >appears to have happened somewhere along the line, but neither I >nor apparently anyone else can pin it down. It's an intersting question but my answer is "probably none." Ultra Fractal is written in Delphi and Fractint in C. The Fractint compatibility formulae are written in Ultra-Fractal's formula language. The source of these is available and IMHO it is indiscernable from the fractint code. Plenty of other programs implement the same forumlae as fractint and many of these are hard-coded in C - I think these are more questionable. btw: can someone give me a link to the old fractint archives from the majordomo days?
