That's because in one case the image is the A plane with 3A^2z the z term, and in the other case the image is in the same plane but using the coordinate T = 3A^2. Changing between A and 3A^2 enlarges the Mandelbrot in that plane by a factor of three and doubles it up radially about the origin, into two somewhat distorted symmetrical copies -- a change of the coordinates in which the plane is viewed. _____________________________________________________________________________________ Get more from the Web.

Which would appear to be the rationale behind BoF's choice of parameterisation. You said as how "The BoF version gives less 'mangled' looking images.". Morgan L.

The journey will not be an easy one to visualize, but by taking it one step at a time, we may come to at least a vague understanding of that next higher space. One of the best ways of understanding four-dimensional geometry is by breaking it down into three-dimensional sections and comparing it to the solid geometry of three dimensions. Keeping this in mind, today's image and discussion remains within the realm of three-dimensional space. I have given today's image a new color palette, which emphasizes the contrast between the low-iteration features that I call Julia stuff and the high-iteration features that I call Mandelbrot stuff. In today's image, as well as in the images to follow, the Julia stuff, which lies mostly in the foreground, is colored with a banded dark blue and red palette. By comparison, the Mandelbrot stuff, which lies mostly in the background, is colored a brilliant bluish-white. Today's image is a perturbed version of the period-4 northeast bud of the Mandelbrot set, which appeared in all its perfection in yesterday's FOTD. The scene has been perturbed by setting initial Z to 0.36775+0i. This perturbation moves the position of the illustrated slice 0.36775 along the real(Z) axis, while keeping the orientation of the slice unchanged. The most striking feature of the new image is the ghost of the original bud, which is still there in the same position, glowing a brilliant blue-white, partially obscured behind the broad but dull Julia-stuff arms in the foreground. In fact, unless the Julia stuff totally obscures the background, giving a blank screen, the remnants of the original bud are always visible in the same position regardless of the value of initial real(Z). Since changing the value of initial Z moves the illustrated slice without rotating it, and the ghost of the period-4 bud always retains the same circular shape, size and position, the three-dimensional shape of the Mandelbrot bud must be a cylinder. This cylinder is not continuous, but broken in many places by the low-iteration Julia stuff. Wherever it reappears however, the cylinder is always in the same location and of the same size and shape. The entire border of the classic Mandelbrot set (but not the filaments) behaves in the same manner, thus the Mandelbrot set can be taken as a three-dimensional collection of parallel tangent cylinders lying along the real(Z) axis. To keep things three-dimensional I have ignored the imag(Z) axis, but I will discuss this aspect when we shift to higher space in a few days. Today's image renders in 30 seconds from the parameter file, and downloads in a minute or so from the Usenet binary group: alt.binaries.pictures.fractals In an hour or so, the image will also be available on Paul Lee's web site at the URL: The fractal weather today was cloudy and cold, with a few flurries of snow, which amounted to little. The temperature of 37F (3C) was too chilly for the cats, who passed the day by the radiators of their choice. It's now time for me to shut down the fractal shoppe and call it a night. But I'll be back tomorrow with a most curious continuation of the 4-D saga. Until then, take care, and don't let hyperspace make you hyper.

The first one slices the M-set in the a plane, with b fixed; the second slices the M-set in the b-plane (which interects the a-plane in only a point!) with a fixed; the third produces straightforwardly the Julia sets. (Want slices of other orientations through the 4D M-set? Write your own formula. :-)) The M-set images show four kinds of colored regions, and show the fate of both critical points. The regions are based on whether both, one, the other, or neither critical point escapes. Generally you see two Mandelbrot shapes overlapping -- the Mandelbrot images for each critical point -- but they influence one another, as will be shown by some of the images in the par to follow. _____________________________________________________________________________________ Get more from the Web.

In today's image, which is centered on the same point as yesterday's, we'll rotate the view and observe what happens to the ghost of the bud. The orientation of today's image has been rotated 52 degrees around the Y-axis (imag[C]) toward the Rectangular direction. The slice of the image now cuts the cylinder at an oblique angle, causing the brilliant remnant of the bud to appear as an ellipse. I have done no stretching or skewing; the features of the image appear in their natural undistorted shapes. Though the Mandelbrot bud enlongates in an orderly manner, the banded Julia stuff stretches at random, with no apparent order at all. The same 4-armed spiral convergence still exists within the outline of the Mandelbrot bud, but the arms have undergone a complete change of appearance. In tomorrow's FOTD I'll rotate the image much further, leading to some totally unexpected results. Today's image is once again a very fast one from the parameter file. If the 30 seconds is still too slow, the GIF file of the image may be found at: and at: The fractal weather today was sunny but quite cold, with a temperature of 34F (1C) that kept the cats glued to their sources of heat. And speaking of being glued, I'm going to spend the rest of the evening glued to the TV, watching a junky old movie or two. Until tomorrow, take care, and see you in 24 hours.

We started with an everyday image of the period-4 bud on the northeast shore of the main bay of the Mandelbrot set. Then we shifted our view 0.36775 along the real(Z) axis, and saw that the bud was gone, but its ghost remained, showing that the bud is actually part of a cylinder. Next we rotated the view 45 degrees around the imag(C) axis, which caused the ghost of the bud to elongate into an ellipse. In today's image, which is rotated 80 degrees toward the Rectangular direction, we continue that rotation. When the plane of our view is rotated 80 degrees, it cuts the Mandelbrot bud-cylinder at such a sharp angle that the once circular bud is elongated almost beyond recognition. The low- iteration Julia material in the foreground is also elongated, in this case to an incredible degree. And whereas the ghost-bud is elongated in an orderly, predictable manner, the foreground material is stretched haphazardly, with no sense of order. This random stretching is characteristic of all Julibrot slices except those oriented in the Julia or Mandelbrot directions, or in certain equal double-rotations between the two. The parameter file of today's image once again renders in less than a minute. Also, the GIF image has been posted to: alt.binaries.pictures.fractals and soon will be posted to: The fractal weather today was mostly sunny but very cold. The temperature of 30F (-1C) kept the cats snug indoors. I see by the wall clock that it's 11pm -- time to shut down. But I'll return in less than a day with the surprising fifth in the series of images. Until then, take care, and you'll rarely get dizzy from rotating a fractal.

G. I'm going to have to analyse these formulas. I really did some of those pars (8, 15, 20 especially). I love the way the finaments seem to join to each other. Like I say, I'll have to have a dam good goggle at those formulas and try to figure how they work. PS. I bet no-one can make a formula that will show the A or B plane *and* the Julia sets using the ismand variable! It kinda fudges up for 4D mandeloids... PPS.

In the previous images we saw that the shape of the Mandelbrot set, with all its buds, exists as an interrupted cylinder in the 3-D section of the Julibrot defined by real(C),imag(C),real(Z). In fact the cylinder shape exists in all 3-D slices of the Julibrot that contain the whole C-plane of the classic Mandelbrot set. In yesterday's 4D-04 image, we saw that by slicing this cylinder at an increasingly acute angle, the cross section becomes an increasingly eccentric ellipse. The limiting case comes in today's image, where the slice has been rotated a full 90 degrees from the Mandelbrot orientation, and cuts the cylinder along its length. In this case, we see the walls of the cylinder as straight edges. The lower wall appears as what I call a bridge. This bridge is actually a side view of the lower valley of the original period-4 bud, which has now stretched to its limit. Such bridges and straight-edged areas exist in all the odd planes, (Elliptic, Oblate, Parabolic, Rectangular), of the Julibrot, in all the rotations between the odd planes, and in all the simple rotations between the odd planes and the Julia plane. It is immediately apparent that Mandelbrot midgets are impossible in the images that contain these straight-edges and bridges, for in such images the Mandelbrot shape has been stretched to infinity, and therefore any midgets will also be stretched to infinity. I have attached the parameters for two versions of the same image. The second image is identical to the first except that the center around which the image rotates has been dropped so that it falls on the straight upper edge of the lower bridge. It is the center of this second image that we will use as the center of the rotation to the Julia orientation. Notice also in today's image that the banded Julia stuff does not stretch to infinity, but it does twist and distort in a most curious manner in the Rectangular plane. For tomorrow's image, the 6th of the series, we shall leave the comforting familiarity of 3-D objects and launch out into the fourth dimension. The surprises we will find will make the trip worth the effort. The parameter files of both of today's images render in well under one minute. To save bandwidth, I have posted only the first image to: alt.binaries.pictures.fractals and to: The fractal weather today here at Fractal Central was sunny and not too cold. The afternoon temperature of 45F (7C) and warm sun lured the cats outdoors for a brief romp before that began worrying for their meal. That's it for another day, but I'll be back in 24 hours, when we'll take off on a trip to Julia land. Until then, take care, and keep those extra dimensions coming.

But all is not lost, for I substituted a nice, (there's that word again), minibrot from the M-Mix4 formula. And the 4-D series will continue one day behind schedule in tomorrow's FOTD. The expression that was iterated to produce today's fractal is 2Z^(-1.2)+0.4Z^(-12)+(1/C). I named the picture "Minibrot Interlude" because there is a Minibrot at the center and it is an interlude between the two parts of the 4-D rotation. I rated the image a 6, which seems about right. The parameter file is a slow one, requiring over 16 minutes to render, and making a download of the GIF image file the better choice. The image file may be found on Usenet at: and in an hour or so at: The fractal weather today was partly sunny, mild in the morning but turning cold in the afternoon. The fractal cats, unable to decide where to spend the day, passed the time indoors in a bad mood. That's it for today.

We generally don't leave many old developer packages up. Check out http://www.fractint.org/ftp/old/dos/ The "fradev" packages have executables. Looks like the earliest one is 20.0.10. Not sure why you would want to try. However if you think there's a good reason, I could put up more old packages. They are mainly good for discovering when a bug started. I do a kind of binary search, trying old versions until I pin point when a bug started, and then it is easy to fix.

Define "bug" :-) Integer math, by definition, has very limited dynamic range. Couple that with the manzpower type (clue: "power") and you see that you are coupling a datatype with limited dynamic range with a fractal type using exponentiation, which requires a lot of dynamic range. The star-shaped figure you found is a typical artifact of integer math, and a charming one at that. Some folks have made spectacular fractals images that depend on these artifacts, and have even complained when we made any change in integer math that changed the artifacts I suggest you leave the web page up (it's a nice image, though it could use something besides the default colors) but edit the text. It's not a bug and not a surprise to experienced fractint users. Just an interesting artifact of a software algorithm designed to exploit the very earliest, FPU-less computer CPUs of the late 1980's era. I don't expect integer math to survive many (if any) future fractint versions, unless we make an extra effort to keep it out of nostalgia.

At this angle the displayed slice cuts through the length of the Mandelbrot cylinder, resulting in features with perfectly straight edges and narrow straight bands which I call bridges. In the previous 4D-05 image, the screen X-axis represents imag(Z), the Y-axis imag(C), and the Z-axis real(C). How then are we to rotate the image to bring the real(Z) axis, which is now the fourth dimension, onto the screen? To find the rotation, we must rotate the entire 4-D Julibrot around the image on the screen, until the image's Z axis represents real(Z). In such a rotation, the screen image will be the axis of rotation, and therefore will show no change as every point turns in place on itself, but the rest of the unseen 3-D slice will change dramatically. Now, as we rotate around the screen's X-axis, the screen's Y-axis will rotate toward real(Z) instead of real(C). We are rotating from the Rectangu- lar direction toward the Julia direction. As the 3-D slice rotates through the fourth dimension in this manner, the shape of the cylinders themselves changes. The originally circular cylinders gradually elongate into ever more eccentric elliptic cylinders, and finally into flat, plate-like features of varying thickness. In today's image, the illustrated slice has been rotated 60 degrees from the Rectangular direction toward the Julia direction. The bridge, which appears as the brilliant feature in the background, is actually part of a 3-D plate. Since the slice of the image is cutting through this plate at an angle of only 30 degrees, the apparent width of the bridge has broadened to twice its previous value. The banded Julia stuff continues to shift and change in an almost random manner, though there is an apparent tendency for it to spread out along the bridge. In tomorrow's image, we'll continue the rotation, showing the changes that take place at an ever-increasing rate as we approach the Julia direction. The parameter file of today's image renders in one minute, about the same time it takes to get to and download the GIF image file from: or from: The fractal weather today at Fractal Central was partly sunny but quite cold, with a temperature of 30F (-1C) that kept even the thoughts of the outdoors from the minds of the fractal cats. I'll return in 21 hours or so with further rotation of the image. Until then, take care, and practice fractal conservation.

An artifact due to the limited _precision_, which is inherent in integer maths, is, of course, a feature. In this case, I think, it's a problem of the limited _range_, but that means, that an overflow wasn't handled correctly, therefore I call it a bug.

Today's image has been rotated until it lies only 10 degrees from the Julia plane. When sliced at this angle, the bridges, which are made of Mandelbrot stuff and are actually plates, appear to have expanded to almost 6 times the width they have when sliced perpendicularly. In today's image, we see the entire lower half of the screen filled with the Mandel stuff that makes up the bridge. The straight edges of the bridge remain clearly visible. The banded Julia material in the lower half of the image has taken on a tortured, stretched, twisted look, which is not very attractive to look at. Also, the four arms in the upper right, which in yesterday's image converged in a vague spiral, have taken on a decidedly more spiral-like appearance. In the next FOTD, we'll rotate the view still closer to the Julia plane, and see what happens to the ever-broadening bridge of Mandel-stuff. Today's image renders in a quick 46 seconds, fast enough to make the download unnecessary. But for those who would still wish to download the finished GIF image file, the file is available at: alt.binaries.pictures.fractals and at: The fractal weather today was partly sunny with occasional flurries of snow. With a temperature of 32F (0C), the fractal cats didn't even think of going outdoors. But I'm thinking of getting busy and finishing that job that's been fighting me most of the evening. I'll reappear tomorrow at about this same time, with the next in the series of rotation images. Until then, take care, and when working with fractals, don't get cold feet.

It's a little problem with rich text and with at least one email client program. The kicker was this line: Oops, couldn't understand the argument: colors0ublahblah when the input was colors=000ublahblah -- somehow, some people had an "=00" go missing. When I saw that, it all fell into place. Clearly, these people have an email client that can handle a certain enriched-text format called "quoted-printable", which I have seen before, and which has markup tags for some function or other taking the form of an "=" and a 2-digit code. In that markup, an "=" itself is represented using such a code (specifically, "=3d"). Moreover, these peoples' email software is clearly interpreting plain text messages as though they were in markup. As a result, when it viewed the par file, it interpreted the "=00" in the color line as a markup tag (though it wasn't intended as such) and it evidently collapsed away into an invisible character or change of format. This disappeared when the line was copied and pasted into a plain text editor that couldn't represent rich text formatting or special characters. This, then, is just the reverse of a problem we had on here once before, in which someone was posting par files with an email client and unwittingly posting quoted-printable markup instead of plain text -- the result was stuff like "center-mag=3d0.3632/-0.7616/0.00001283", which Fractint choked on. The devil of it is that quoted-printable looks enough like normal text that the problem isn't glaringly obvious, unlike when something shows up as HTML. Just Say No to weird markup-using mail readers. :-) _____________________________________________________________________________________ Get more from the Web.

The 'net and I go back far enough that I still view it as a volunteer/amateur/academic/gummint deal rather than a taken-for-granted utility such as water and power. When it burps, I tend to wait and see...it's usually fine later. (This actually works well in many areas of life.) I'm impressed by the wealth, texture and richness of the web, and I'm constantly amazed by the contributions of the myriad authors of the content. I do have some idea how hard it is to create and maintain a website, both artistically and technically. I'm also very impressed by those that take on the pressure of a daily contribution. That is no small matter. (I can't begin to imagine how people like Scott Adams do it.) I ramble. The point is, this is supposed to be FUN. Relax, have an eggnog. The fractal will be there later. If not, and one is terribly concerned about it, perhaps direct email to the webspinner is a wise choice of action. -- |_ CJSonnack _____________| How's my programming? | |_ http://www.Sonnack.com/ ___________________| Call: 1-800-DEV-NULL | |_____________________________________________|_______________________| Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Barry N.

It may render in only a few seconds, but it's still more convenient to view it on the Web. It only takes a few seconds to download and display, and to view it on the Web involves three mouse clicks and a few seconds of time. To render it myself, on the other hand, involves * Painstakingly selecting all of the text and hitting ctrl-C to copy it. * Opening a text editor and hitting ctrl-V to paste it. * Saving it to some .par filename or another in the fractint directory. * Opening a DOS window, going to the fractint directory, and starting fractint. * '@', f6, enter the par name, enter, enter. * Wait for it to render. This is a fairly long and tedious sequence of steps that cannot be automated. I much prefer three mouse clicks, especially as the download is generally as fast on my 56k modem as the fastest FOTD renders at 1024x768. Usenet is even worse, of course: * Find abpf, if my ISP even carries binaries -- most don't. (If it doesn't, find it on deja news, assuming they carry binaries...) * Find the messages with the FOTD, somewhere amid all the spam. * Download and view each message with a part of the fractal, and hope they are all there. Paste them (careful to put them in order; they might have arrived on my news server out of order) in sequence into a file in a large-capacity text editor. Save it. * Search the Web for a uudecoder of some sort. * Scan the uudecoder for viruses, assuming I can even find one in this day and age. * Assuming it proves free of infections, use it on the saved text, thereby generating a gif. * Run an image viewer (or Fractint). * Open the gif. _____________________________________________________________________________________ Get more from the Web.

Does he have the ability to get an ext cable modem, or DSL from the phone co??

It's never the promised T1speed, but it's a heck of a lot faster than dial-ups are.

I know my general level of frustration w/ the world (in my case, governed almost entirely by download-intensive internet functions, for work and pleasure) almost vaporized as soon as I ceased having to spend 40-45s/online minute waiting.

Life became less irritating and more fun. Perhaps 100mg of T1 speed downloads, administered 2-3 times / day, would be just what the doctor ordered.

Just a thought . . . .

What have you been smoking? Either the page is there on home.att.net, or it
is not; which ISP I happen to be on doesn't affect what home.att.net's Web
server serves for a given URL. At least, it shouldn't; if home.att.net's Web
server serves different stuff for the same URL depending on what the
requester's IP address happens to be, then IMO that Web server is broken,
and it's *your* ISP that ought to be changed.

I have a working email via my ISP. I don't use it to post on Usenet or open
mailing lists, for reasons that ought to be obvious.

>...if you were too lazy to spend the few seconds render time...

It may render in only a few seconds, but it's still more convenient to view
it on the Web. It only takes a few seconds to download and display, and to
view it on the Web involves three mouse clicks and a few seconds of time. To
render it myself, on the other hand, involves

* Painstakingly selecting all of the text and hitting ctrl-C to copy
  it.
* Opening a text editor and hitting ctrl-V to paste it.
* Saving it to some .par filename or another in the fractint
  directory.
* Opening a DOS window, going to the fractint directory, and starting
  fractint.
* '@', f6, enter the par name, enter, enter.
* Wait for it to render.

This is a fairly long and tedious sequence of steps that cannot be
automated. I much prefer three mouse clicks, especially as the download is
generally as fast on my 56k modem as the fastest FOTD renders at 1024x768.

Usenet is even worse, of course:

* Find abpf, if my ISP even carries binaries -- most don't. (If it
  doesn't, find it on deja news, assuming they carry binaries...)
* Find the messages with the FOTD, somewhere amid all the spam.
* Download and view each message with a part of the fractal, and hope
  they are all there. Paste them (careful to put them in order; they
  might have arrived on my news server out of order) in sequence into
  a file in a large-capacity text editor. Save it.
* Search the Web for a uudecoder of some sort.
* Scan the uudecoder for viruses, assuming I can even find one in this
  day and age.
* Assuming it proves free of infections, use it on the saved text,
  thereby generating a gif.
* Run an image viewer (or Fractint).
* Open the gif.

Oops! The limit for disk video in version 20.0 is 32767x32767. We forgot to update the discussion about disk video modes. I'll fix it in patch 5, since I'm uploading patch 4 this evening. If you use the latest developer's version, you can pick any disk video mode, start the fractal, and then go to the screen to set the resolution up to the limit of 32767x32767.

In fact, we are only 4 degrees from the Julia orientation. At this angle, the Mandelbrot stuff, which has already expanded to infinity horizontally, has stretched to over 14 times its normal measure vertically. Only the top part of the Mandel-bridge now appears in the close-up 4D-08 image, while the emerging spiral toward the upper right has become quite well defined. A narrow band at the top of the main band of brilliant Mandel stuff is the side view of a sub-valley in the main valley. A careful examination will show the Mandel bridge beginning to lose its definition as the increasingly narrow angle emphasizes the irregularities along its edges. However, a high enough maxiter would smooth these irregularities. The bottom of the image has been overwhelmed by an intruding mass of banded, low-iteration Julia stuff. This mass will clear away as we rotate ever closer to the Julia direction in future FOTD's. The image is filled with spirals, all of which converge clockwise. But look carefully in the lower left corner, where one small spiral converges counter-clockwise. The spirals are like people -- there are some that just have to be different. As I mentioned at the start, two images are attached to this discussion, the second image being a view of the entire fractal. This image, 4D-08a, which is already taking the shape of a Julia set, is perhaps more striking than the first. In it we see a proto-Julia set, with a grossly enlarged band of Mandel stuff cutting straight through it. This band is still a side view of the lower valley of the northeast period-4 bud, though it has long since lost any resemblance to a Mandelbrot valley. The supernumerary bands at the edges of the brilliant band are sub-valleys of the main valley. The first image renders in one minute; the second takes 1/2 minute. These times do not include the cutting, pasting and renaming necessary to change this letter into an executable parameter file. Those who would rather not cut, paste and rename may find the GIF image files posted to Usenet at: and in an hour or so to the W.W.Web at: The fractal weather today was cloudy and a bit milder. But the temperature of 43F (6C) was still too cold for the pampered fractal cats, who spent the day by their radiators, wishing summer were here. Well, the day is done and I'm exhausted. It's time to shut down the fractal shoppe, call it a day, and watch the continuing election nonsense on TV. My guy has become as big a jerk as the other guy, so I've long since stopped caring who finally gets to be president. Until next time, take care, and have the patience of Job.

The first image shows the local scene; the second image backs off far enough to reveal the entire almost-Julia set. Yes, we're almost there. Today's rotation takes us to within 3/4 degree of the Julia plane. At this angle the thickness of the brilliant Mandelbrot bridge has been increased to over 76 times its normal thickness. We see the straight edges of the bridge now becoming quite ragged and increasingly indistinct, but the increasingly well- developed spiral in the upper right corner is now fully formed. All spirals converge clockwise, except the brilliant blue spiral near the center, which to be different converges counter- clockwise. This first image is almost but not quite a Julia set. The second image of the day, which shows the entire fractal, reveals how the width of the bridge has increased until it fills almost the entire scene. Only the top 1/4 of the image and a tiny area near the bottom are not covered by the grossly enlarged projection of the lower valley of the period-4 northeast bud of the M-set. The first image renders in 3-1/2 minutes, the second in 23 seconds. For those who prefer their fractals pre-rendered, the rendered images are available on Usenet at: alt.binaries.pictures.fractals and on the Web at: The fractal weather today was typical of this part of the world at this time of year. The partly sunny skies were fine, but the temperature of 41F (5C) was too chilly for the fractal cats. And it's now time to shutter the fractal shoppe and settle down for the evening. I'll return tomorrow with the next to last in the series of Mandelbrot to Julia rotations. Until then, take care, and I'd walk 100 kilometers to see a four-dimensional object that was not a projection into three dimensions.

Date: 09 Dec 2000 22:25:01 -0500 Finally got around to trying it last night. Fractint animator has a bug -- it always looks for fractint in "c:\fractint" regardless of the setting on the "system" tab. (I changed it to "e:\fractint", which is its location on my system, and tried to do the first.par demo, and it balked complaining that it couldn't find fractint in "c:\fractint".) Unfortunately, this is a showstopper on my system, and for anyone else who has put fractint in a non-standard directory or on a different partition or drive. _____________________________________________________________________________________ Get more from the Web.

Rude? I wasn't implying any laziness or anything -- just remarking that although I found it in a less-than-most-recent version I had reason to believe it existed in the most recent version as well, in case someone might otherwise think I was reporting an old, possibly fixed bug. _____________________________________________________________________________________ Get more from the Web.
