There are still some chipset issues to be worked out (the K-7 requires a new chipset to support it) but if it even comes close to the expected performance I will go with it. > I guess when you do not want to make a 60% profit, you can sell your processors for > less money! Amen! Isn't competition a wonderful thing? BTW, I have my K-6 networked right now and it works fine. It did take a few days for it to become happy with the network (now I know why, Thanks!) but the bugs are finally gone.

Do you mean that AMD has a 3DNow optimized, software rendering Direct3D driver, or what? 3DNow doesn't actually give you hardware 3D acceleration; in fact the only point on the rendering pipeline (whether OpenGL or D3D) that it really helps with is transforms (which most of the consumer 3D accelerators up until now don't handle). I believe the M$ OpenGL DDK has 3DNow acceleration for transforms, which helps speed things up a bit whether you have hardware acceleration or not, but the software GL driver still returns a nonaccelerated pixel format through WGL. If Direct3D always says you have acceleration if you have 3DNow, that's a bug.. If Motocross Madness will not run unless D3D returns an accelerated mode, that's also a bug Adam > It enables the system to use software that actively seeks a 3D accelerator > (ie:MS Motocross Madness), without an added card.

What happens then? Also, look in your 'sstools.ini' and see what the "video=" line is set to. Try commenting it out (put a ; in front of it) or set it to a lo-res mode like "video=F3" and see what happens. As to running Fractint in real-mode DOS (no windows running), check that you are not loading the real-mode compression drivers 'drvspace.bin' or 'dblspace.bin'. These are hidden files that are sometimes placed in your root directory and are loaded before windows boots, then unloaded and replaced by the windows 32-bit drivers if needed. If either of these files is in your 'C:\' directory, move them somewhere else, then boot up into dos and see if fractint will run. Hope this helps, Phil D.

It relates to question 2. Especially in the Julia set, which is in the "dynamic plane" it would be nice to be able to follow the orbits relative to the actual julia set. But since orbits and the actual fractal are in separate windows, it is hard track where the one is relative to the other. During picture generation, orbits appear in the same window as the fractal, and it would be nice to be able to do this with manual orbits explore mode. I tried using view windows and setting the view window of the main fractal to the size of the whole screen, hoping that the orbits window would overlap, but it is too clever, and the orbits window became small again.

My question is this: Where on earth did M. Barnsley *get* these from? Julia #3 is the only one which looks remotely recognisible (and indeed its graphical form is more "Juliaish"). That first term looks a bit like real(Z)^2 - imag(Z)^2, which is the result of real(Z^2). But the rest? What is the mathematical reasons behind it? I know a lot of people out there simply type formulas into FractInt and get pretty pictures, but I can't imagine someone like Barnsley inventing them out of thin air. What's the background? And how do you work out the derrivatives of functions like that?!?! P. S. I too would like to know out to super-impose orbits over the fractal and not a seperate window. FractInt does it while rendering, but not it seems once it's finnished... P. P. S. I'm talking to you Tim: So you can't generalise Complex Numbers into a 4D field... But *can* you generalise them into a 3D set without loosing any field properties? Just how complicated is the proof of there being no 4D fields (i.e. would someone like me understand it)?

Just how complicated is the >proof of there being no 4D fields (i.e. would someone like me >understand it)? > No. Whether an explanation would satisfy you depends on what you already know (any group theory? Since you seem to know what a field is, I assume you know what groups/rings/fields are, in which case skip to the *-*-*-*; or even the **-**-**, but for the benefit of people who aren't familiar with either - and then only if they're interested enough ...) So first off I'll sketch out what a group is. A group is a set of things and an operation that combines pairs of things to produce a thing that is also in the set The defining properties of a group are as follows. Assuming that we use '+' to denote the operation (note that '+' doesn't necessarily mean addition as we know it, just something that is compatible with these rules): 1) For all a, b, c in the group, (a+b)+c = a+(b+c) (associativity) 2) There is an element e in the group such that a+e=e+a=a for all a. (identity) (It can be proved that there can be only one such identity). 3) For all a in the group, there is an element b in the group such that a+b=b+a=e (inverse). Quick example: addition mod 4 + | 0 1 2 3 0 is the identity --+-------- 1 is the inverse of 3 0 | 0 1 2 3 1 | 1 2 3 0 2 | 2 3 0 1 3 | 3 0 1 2 An extra property may be included, stating that the operation commutes: 4) For all a, b in the group, a+b=b+a. A group with this property (the example just given is one such) is known as an "Abelian group". Now, a ring. A ring is an enhancement of an Abelian group. As well as having all the structure of an Abelian group, rings have a second operation '*' and further rules: 5) For all a, b, c, a*(b*c)=(a*b)*c (so both operations are associative) 6) For all a, b, c, a*(b+c)=a*b+a*c and (b+c)*a=b*a+c*a (distributivity) Again, commutivity is optional: 7) For all a, b in the ring, a*b=b*a. A ring with this property is called a "commutative ring". An example would be the ordinary integers with the operations of addition and multiplication. Important thing to note about rings: There is no guarantee that every element of the ring has an inverse under '*', nor is there any guarantee that there is an element '1' such that 1*a=a*1=a. To point to the previous example, integers don't come with integer inverses (except 1 itself). To illustrate the second non-guarantee, consider the set of _even_ integers with familiar addition and multiplication. The resulting structure satisfies all seven rules, but there is no number n such that n times m equals m for all m. Now we can get on to a field. A field is a ring. It is a commutative ring. It is a ring in which the two properties noted just now _do_ hold. Every nonzero element has an inverse under '*', and '*'ing an element by its inverse gives the same unique element (known as 'unity' and conventionally written '1'.) Nonzero? Ah, remember that the '+' operation that makes our structure a group has an identity element. At the time I've written it 'e'. Now I'm changing my notation and writing it '0' and calling it zero. A nonzero element is any element other than 0. This, incidentally, is the rule broken by "hypercomplex" numbers. The rational numbers form a field. So do the reals. And the complex numbers. *-*-*-* Complex arithmetic has a group structure. Consider that a complex number is one of the form a+ib, where i has the property that ii=-1. For convenience one can draw up a little multiplication table: + | 1 -1 i -i (I'm using '+' because this is a group) ---+------------ 1 | 1 -1 i -i This group is named "Z2+Z2"; it is equivalent to the group -1 | -1 1 -i i formed by adding _pairs_ of integers mod 2. i | i -i -1 1 -i | -i i 1 -1 Quaternion arithmetic has a group structure as well. Consider that a quaternion number is one of the form a+ib+jc+kd, where i, j, k has the property that ii=jj=kk=ijk=-1. One can again draw up a multiplication table, but it would not necessarily be very illuminating. You can do it if you want: It has eight elements 1, -1, i, -i, j, -j, k, and -k. Just remember things like the fact that ij=-ji (multiplication is not commutative - violating property (7) above and disqualifying Quaternion arithmetic as a field). The group generated by quaternion arithmetic has a name as well: Q4. **-**-** At this point I'm going to wave my hands and gloss over some of the most powerful and deep theorems of group theory. But although _understanding_ them requires a textbook's worth of groundwork, for our purposes enough of their results can be obtained by straightforward brute force: Build up every possible multiplication table of sizes 1x1, 2x2, 3x3, 4x4, ...; making sure that each one satisfies properties (1)-(3) of a group, and is distinct and not simply a relabelling of elements or a reshuffling of rows and colums of another. I'm just going to give the result: how many groups there are of various sizes (I'll even name them). 1-element groups: One. Z1 2-element groups: One. Z2 3-element groups: One. Z3 4-element groups: Two. Z4, Z2+Z2 5-element groups: One. Z5 6-element groups: Two. Z6, D3 7-element groups: One. Z7 8-element groups: Five. Z8, Z4+Z2, Z2+Z2+Z2, D4, Q4 Zn represents "addition mod n", Zn+Zm means adding pairs of integers mod (+=). D3 and D4 are the symmetries of an equilateral triangle and a square, respectively (the elements of the group being rotations and reflections, and the operation a+b meaning "do a then do b" - the identity element is of course "do nothing"). Q4 is quaternion arithmetic. To generalise complex numbers into higher dimensions, what you need is an arithmetic structure that contains the structure of complex arithmetic. Of all the groups just listed, the _only_ groups that contain such a structure are the complex numbers themselves, and quaternions. In particular, for a 3D generalisation, the group would need six elements (1, -1, i, -i, j, -j). There are only two six-element groups: addition mod 6 (which obviously is inadequate), and the symmetries of an equilateral triangle - which can also be shown to be unable to support complex arithmetic.

There is another group with enough structure to support complex arithmetic, and I did list it. Hypercomplex arithmetic has the same structure as the group Z4+Z2. The relationship between the components of a hypercomplex number and pairs of integers mod <4,2> is as follows: 1 = <0,0> ij=ji=k <0,1><1,1>=<1,1><0,1>=<1,2> -1 = <0,2> jk=kj=-i <1,1><1,2>=<1,2><1,1>=<0,3> i = <0,1> ik=ki=-j <0,1><1,2>=<1,2><0,1>=<1,3> -i = <0,3> ii=jj=-kk=-1 <0,1><0,1>=<1,1><1,1>=<1,0><1,2>=<0,2> j = <1,1> ijk=1 <0,1><1,1><1,2>=<0,0> -j = <1,3> k = <1,2> -k = <1,0> > >Absolutly fasinating!

I tried changing the shortkey assignement to the video-disk modes, I tried changing them both in fracti= nt and in all of the makegif*.bat=B4s.

The second one is the homepage of Michael Freeman (http://www2.capcollege.bc.ca/~mfreeman/). He has developed a suite of little programs (only Mandelbrot-Sets), requiring parameter inputs (i.e. coordinates) that can be obtained via a fractint par file. His programs have the following advantages: a) truecolor output (tga files / continous potential / colorfile editor included, but some manipulation with a text editor sometimes helpful) b) unlimited resolution, which is very interesting for high quality output (I made most of the pictures on my walls using resolutions of up to 8400 x 6300) [c) anti-aliasing program: useful for generating smaller images from a larger one / enhancing output quality] Ralph Feltens 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Gedeon Peteri Subject: (fractint) Updated Chebyshev formula file Date: 10 May 1999 10:13:39 -0400 Morgan L.

I intend to add in the capabilty to weight choices of several images in the next version but that really needs a break from the somewhat restrictive DOS memory limitations which we currently operate under. Phil McRevis is currently puting in some sterling work in that direction, nice one Phil! The main problem with building such GA systems is deciding on a fitness funcion, ideally it would be nice to be able to select a favourite image from a few generations and then let the program take over once your choices were reasonably consistent.... this sounds like a job for a neural network of some sort but I know little of such things and would welcome any input from anyone here who is experienced in programming them... drop me a line if you're experienced!

If you do not have much open space (say less than 300 MB) on the primary master, Windows will have a hard time with its virtual memory. (I personally have 256MB RAM, and Windows uses most of it.

Bresslau could you pretty please set your date to now instead of jan. 1998? It's a bit annoying to have to search through all my messages to get yours. And on the subject...Having your computer learn your prefs is a nice idea, and I saw this once on a special from Super Channel about Chaos/Fracrals etc...that was over 3 years ago however. It was at the IBM labs in Britain about evolving "lifeforms". Difficult to explain this since it's been a while. Though the whole system ran on AIX, instead of your everyday DOS/W9x systems, and was most difinitley not Fractint...But implementing such a thing into fractint would require a major rewrite of some of the code I think. But I do recall that the next version will have evolving fractals. How much you can tweak/control this (or not) I don't know. What I would like to see is a more complex system of functions, right now we have a lot of trigonometric functions (cos, tan, cosh etc.). It would be nice to have some really interesting things in fractint like, PDEs/ODEs (Partial- Ordinary Differential Equations). I like these a lot, since now i know there's a whole lot more to them than just the Lorenz/Rössler equations.

Can I choose between two modes, one normal and one with lots of free mem?<<< Hello again Bresslau, To get the most memory for DOS sessions in Windows95, put the following lines in CONFIG.SYS: device=c:\windows\himem.sys device=c:\windows\emm386.exe noems DOS=HIGH,UMB I think the noems parameter is OK because fractint uses xms, not ems, but I might be wrong. You could try it without noems. If you are loading anything else into memory in config.sys or autoexec.bat, try loading them into high memory, for example in config.sys: DEVICEHIGH=C:\WINDOWS\RAMDRIVE.SYS 1536 512 128 /E or in autoexec.bat: LOADHIGH c:\windows\command\doskey.com Also, if you are loading hardware drivers in config or autoexec, you can usually take them out and use the 32 bit Windows 95 drivers instead. For example, when you upgrade Win 3.1 to 95, it will leave the CD ROM drivers in config.sys. However, almost all CD drives now have Win95 drivers, so you can use those instead which will give you more DOS memory. You must reboot after making these changes. If you still get out-of-memory errors after trying the above, it could be that fractint.exe is corrupt. Corrupt or virus infected exes often give out-of-memory errors. Please feel free to email me privately if you have any more questions about this.

It runs for almost two months and had produced 5 generations. Two new appeared only in the last two days. It makes me happy to see progress on the page. I am a fractint fan since early highschool and I swore to my self a long time ago that I'd learn all what's behing all those breathtaking images. Recently I had to do a project in the field of GA and while searching for a subject I found out that it is possible to "mate" fractal formulas (a similar project somewhere on gatech.edu exists). So I developed Genum: I wanted to learn everything (except LHA compressing, so I used a library) and thereso Genum is a completely standalone in drawing and "mating" the fractals. Of course that's a problem: I can't get the same images using fractint with the same formulas. Genum has a bug but I haven't found it yet. But it produces nice images so I let it go. Concerning the fitness function Robin mentions and the ability to write a program that would "second-guess" someone's pick: Just to discurage you: read "Shadows of the Mind" by Roger Penrose on the subject. An atempt to write a program that would guess someones visual taste is an atempt to define the taste of a person, furthermore the attempt to predict such a taste I would consider highly entusiastic. Now, I guess that you don't want to do that. What could be done at our best is to base the choice (the fitness fn) on some kind of similarity to image (or images) previosly indicated by a human. But that of course would not be anything near to "implanting" one's taste into the code. _____ http://eon.pmf.ukim.edu.mk/~milkman/ [coming soon] 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Ognen Ivanovski" Subject: Re: (fractint) Re: Genum Date: 14 May 1999 21:26:59 +0200 I plan to distribute the source code freely as a simple instalation package but you have to give me time for that.

Available hard drive memory was down to about 300 meg.. I thought that adding a second hard drive and restructuring the system would solve the problem. However, even with 1.5 Gig on the primary master, I was still having virtual memory problems. The swapfile seemed to be managed improperly by the system, growing to immense size. Switching the swapfile to the secondary master with about the same amount free solved the problem and the swapfile has remained at a reasonable size. I don't know why it works, but it does.

No, you are not correct. >If so, that seems to be a rather absurd implication. If it were so, it would indeed be absurd. >If not, please clarify. Okay, I'll try to spell it out. To start, it is obvious that those who enjoy fractals have an interest in math, and it is also obvious that those who enjoy fractals also have an artistic sense. Every person who runs any fractal generating program is to some degree both an artist and a mathematician. But some are more attracted to the math aspect, and others to the artistic side of fractals. I am assuming that by the term "programs other than Fractint" you mean Ultra Fractal. When the Fractint list began about two years ago, it was nearly engulfed by a flood of parameter files, which came in at a rate of sometimes near 100 per day. The comments accompanying these files constantly asked questions such as, "when will Fractint support true-color?" It was obvious that such features were much desired. Then the Ultra Fractal list was formed, and those who had filled the Fractint list with par files moved to the UF list, and began filling it with their par files. And why not -- UF is faster and has many of the features that the Fractint list posters were clamoring for. As a result, in a period of a month or so, the volume of traffic on the Fractint list dropped from 50 or so a day to only one or two messages per day. Concerned about the lack of traffic, one of the list subscribers, (I think it was Bresslau), posted a test letter to see if the list was still working. I replied, assuring him that it was. I added a comment to my reply, speculating about how we might raise a bit more traffic for the Fractint list. Since those who were seeking more artistic versatility in their fractal program have found it in UF, I suggested that the Fractint list should emphasize the math aspect of fractal seeking. I did not even think of denigrating the mathematical ability of those who switched to UF, just as I would not denigrate the artistic ability of those, like myself, who stayed with Fractint. BTW, I am a subscriber to the UF list, and have tried the program. I did not continue using it because I am really not that interested in things such as multiple layers, etc. (Again, no offense intended against those who use layers.) Also, I generate fractals on several machines, and two of them still run Windows-3.1, which does not support UF. If you still feel offended, quote the phrase that offends you, and I'll give further clarification.

I'm glad to hear that. I agree completely. Each has their own opinions about the various programs and why they use them. All the programs are tools, and while different programs have different capabilities, they are just tools for the user to gain whatever pleasure from that they choose. >BTW, I am a subscriber to the UF list, and have tried the >program.

Unfortunately some people are not as lucky as she is and do experience problems. Specifically, Windows 95 and 98 both can do strange things when managing memory in excess of 32MB.

I wrote a perl script some time ago that did what partobat does and more. However, the script was written to generate BAT files for msdos, not unix shell scripts. I don't even know where the script is anymore, since I wrote it for a need at the moment. However, its not hard to write something similar. (I have no idea why the partobat.exe author didn't include the source; it can't be more than a page or two of C code.) -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Bresslau" Subject: (fractint) Choose yur picture before downloading the par.

Anyway, a simple CGI would probably be fine, and all that would be necessary for the graphics would be a thumbnail. The user could download any pars that they were intrigued by and view the larger graphic at their leisure.

For example: f(x)=k * x ^ a In the 1/f fractal noise case, we have x being frequency, and the exponent a = -1. The 'fractal' bit here is self-similarity; when x is scaled by a factor (x -> Bx) the overall shape of the function remains unchanged, although the constant factor k is scaled (k -> k * B ^ a). Noting that our x is frequency, what we really have is a homogeneous power law which describes the frequency domain. This is essentially a Fourier Series. Now to the 'noise' bit. If we have an electrical or audio signal whose Fourier Transform ('cos we can't really take the Fourier Series in real life...) has a shape described by a homogeneous power law with exponent a = -1, then we have a signal that could be deemed '1/f fractal'. If it were simply noise, then it would be '1/f fractal noise'. This term has become quite ubiquitous due to the nature of many statistical systems in real life, for example rainfall figures, and the stock market. These systems show fluctuations that have self- similar shapes in the time domain (i.e. a period of fluctuation over a small amplitude range and a short period of time (e.g. stock prices in a week) could look very similar to a period of fluctuation over a large amplitude range and a long period of time (e.g. stock prices in 10 years)). This means these systems will obey homogeneous power laws in the frequency domain. Note that the exponent is not necessarily a = -1. Hence all 'fractal noise' is not necessarily '1/f' in nature! Lastly, a good reason for why '1/f' is significant. Apparently, when listening to audio with a frequency spectrum which obeys a homogeneous power law with an exponent of a = -1, the stimulation of the brain by the ear is very constant. This means that music which has a roughly '1/f' characteristic sounds pleasing, and is relaxing. Much of the music we listen to, especially classical, has this characteristic. Hope this provides the information you require. Iain G.

I haven't even taken time to download UF because I'm working on extending fractint by getting rid of the "medium" memory model and adding a porting interface that makes it easier to port fractint to some other system like a Mac or BeOS. Lots of people who were in a position to contribute something to fractint were put off by all the restrictions of working in a 640K overlaid medium-memory model. The code itself goes through many contortions and backflips just to fit into this 8088 style model of programming. The next evolution of fractint will leave 8088/80286 machines behind but will provide a significantly easier environment for casual programmers to add new features. -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Allison, Joshua" Subject: (fractint) Fractint on NT Date: 20 May 1999 15:17:34 -0500 Has anyone had any experience with fractint on NT?

My impetus for extending fractint doesn't have anything to do with "pressure" from UF. I have written my own fractal software in the past, mostly to test out little tricks for isolated images -- see where I wrote my own software to compute the hue and texture colorings of M. I had considered doing an UF-like thing whereby I wrote my own fractal imaging app from the ground-up. However, every time I considered doing that it always stuck in my craw that I'd be reinventing everything fractint already had. In the end, I decided it would be better for me and the fractal community at large if I extended fractint rather than reinvent the wheel. My investigations into fractint source code quickly revealed that I wouldn't be able to add any of my whizz-bang ideas to fractint until a stake was driven into the heart of the medium memory model first. I was hoping someone else would do this, but noone waved their hands and said "I'll do this!". Sure, everyone wants to do a Win32 "port" but noone wants to deal with the realities of such a port: medium memory model must go. This is a rather unglamorous, extensive and tedious programming task that doesn't have the ego-salve of glory that most people seem to want. So rather than contribute back to the fractint community, they lurk on the sidelines or reinvent the wheel to build a shrine to their own ego. Does anyone here truly have any idea how huge fractint is? In source code its about 137,700 lines of source code comprising about 500K of storage. When printed out double sided it amounts to a 6 inch thick printout -- not including the help file sources. Its a minor miracle of software engineering that it still runs on an 8088 with 640K of memory. This is, of course, my opinion and not any "official" statement on behalf of fractint developers. If you were offended by what I said, then I must have said something important. :-) -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: RParracho@aol.com Subject: Re: (fractint) quickie pars Date: 20 May 1999 19:52:35 EDT In a message dated 5/20/99 6:59:02 PM Eastern Daylight Time, legalize@xmission.com writes: > If you were offended by what I said, > then I must have said something important. :-) I wasn't offended, nor did I mean to offend.

Having an intuitive understanding of how one can create a 1/f signal, and where they occur naturally is also worthwhile, so I will try and explain what I learnt. To start with, 1/f signals are contrasted with "white noise" and "brown noise" White noise is the typical hissing you hear if your radio receiving on a frequency that no one is transmitting on. To generate a white noise signal with dice would simply be a matter of having say 3 dice, and throwing all three and totalling their scores at each throw. The possible range would be from 3 to 18, but 3's and 18's would be rare compared to 10's and 11's, in fact on average the throw would be 10.5. The popularity of the various scores is a "bell curve"/ normally distributed. The sequence is a white noise signal, and example would be 8, 12, 15, 4, 17, 11, etc. (The sequence can be shifted to be 'symmetrical' about 0 by subtracting 10.5 from each value.) Brown (for Brownian) noise is obtained by renumbering one dice as follows -2.5, -1.5, -0.5, 0.5, 1.5, 2.5 Now, start on 0. To get the next value in the sequence throw the dice and add it to the previous value. This is like a "random walk", and the motion of microscopic particles in solutions is "brownian". Now, white noise is always totally random, and the signal never "correlates" with itself. I.e. take a splice of the signal and compare it with all other parts of the signal and there is always no correlation, no matter which splice you start with and which other part you compare it to. This is a "power function" which is 1 for a phase shift of 0 (i.e. the signal only compares to itself exactly), and 0 everywhere else. Gardner says this is a 1/f^0 signal. A brown signal is a 1/f^2 signal (I have no idea why), so midway between them is 1/f noise. Now, my point was to show how to use dice to generate a 1/f signal, since knowing that its power function is 1/f doesn't really help intuitively (at first anyway). My approach is as follows: similar to the way the dice was numbered for brown noise, number each of three dice -2.5, -1.5, -0.5, 0.5, 1.5, 2.5 Start with 0. For each subsequent value of the sequence, throw and total all three dice, but divide by three and add to the previous value. It is similar to brown noise. In both brown and 1/f, the next value depends on the previous value + some random value. But in a brown signal, this random value is "uniformly distributed", whereas in a 1/f signal this random value is "normally distributed" (i.e. bell curve). Where do 1/f signals arise naturally? Almost everywhere in nature, and in real life: the levels of a river, the price of a stock market share, the density of the traffic etc. The general rule is anything that that behaves almost randomly, but depends on its previous state. The next sample will vary from the previous sample by some normally distributed random value. The chances of a smaller variation from the previous value are higher than the chances of a larger variation. Melodic music is 1/f in that the next note differs from the previous note usually by a small number of tones, but sometimes by a larger difference. Also the note durations are like a 1/f signal. Martin argues that we enjoy melodic music because it is like our everyday experience in life which is full of 1/f signals. (Note, the process I have described for generating a 1/f signal is different from Gardner's simpler version which he states only generates an approximately 1/f signal. Also, the white signal process I described could have been "normalised with the others" by subtracting 10.5 and dividing by 3). Hope that helps. ------------------------- Randall Britten 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Guy Marson Subject: Re: (fractint) Some Useful Fractal Links Date: 21 May 1999 13:39:23 +0200 At 22:27 20.05.1999 -0500, you wrote: >http://archives.math.utk.edu/topics/fractals.html > >Submitted by Bob Margolis. > Thanks Bob, very useful!!!

Dollevoet" Subject: (fractint) printing fractals -- recent messages Date: 21 May 1999 23:23:02 -0500 I have managed to print a few fractals at 8"x10" without paying for an image editor or a printer. The results were more or less satisfying to me. Bundled with my Microsoft Office 97 software package is Microsoft Photo Editor: reads/saves common graphic file formats converts 256 color GIF image to 24 bit true color resize/crop brightness/contrast/gamma despeckle sharpen/soften texturizing printing only one level of un-do no batch processing Using MS Photo Editor, I converted Fractint GIF format images, generated at 1600x1200 resolution, to true color JPG files which I saved on diskettes. The JPG files averaged about 130 KB. I printed the images at slightly larger than 8"x10" on a Kodak Picture Maker printer located in a near-by department store. The price was $7 US per print on 8.5"x11" heavy photo print paper with glossy coating. The Kodak Picture Maker is a kiosk style machine that includes printer, monitor, scanner, CD-ROM reader and 1.44 MB diskette reader. The CD-ROM reads only a Kokak proprietary file format, and the diskette reader accepts Kodak and JPG formats. Some brightness/contrast/color adjustments are available. The printer is a continuous tone dye sublimation type at 600x600 dpi resolution in four passes. I have found this to be an economical port of entry for printing fractal images.

The correct way to bring bugs to our attention is to email myself, Jonathan, or Robin (just one of us). Include as much detailed information as possible so we can duplicate the bug. This is a necessary but not sufficient condition for us to work the bug. We also have to have some time, and some clue what to do. I don't object to discussion of bugs on the list as long as everyone understands that such discussion is not a substitute for a good, detailed, specific bug report emailed to me or the other authors.

Try 1024x768. It's sensitive to the exact zoom factor and pixel size in mandelunits.

Date: 23 May 1999 23:31:08 -0700 Hi, Vanna! Well, I think my top 5 (and not necessarily in any particular order) are (at this moment in time): 1 - Practice makes perfect. It takes awhile to learn the program, and you have to (or at least, I had to) develop an eye for identifying local areas of interest to zoom in on. So don't give up! Keep trying. 2 - Dissecting the par files that are posted to this mailing list can be a great help, too. By changing one variable at a time, you will begin to see patterns that you can use in developing your own images. 3 - Print out the documentation included in the Fractint program. And learn how to navigate through it. Great stuff there! 4 - Try to reason out the problems that confront you in using the program. But if you can't figure something out, ask questions. This is a good forum for questions. 5 - Learn how to design your own colormaps. Or you can download some nice ones from http://wizzle.simplenet.com/fractals/fractint_maps/newmaps.htm. It's amazing the difference that a good colormap can make! Happy fractaling!

This is at a 45 deg angle, and bilateral. In orders 2 & 38 the images produced are very close to being identical! Zooming in and changing the angle to 45 deg results ni the symmetry becoming vertical, and quite striking. So far these are the only 3 orders I have found with this symmetry, and I can't discover a numerical pattern progression so far. I have read the notes on Lyapunov types in Fractint - is there any more documentation out there on the type? Any answers about to the symmetry of these orders - or is it just a strange coincidence?

That way if passes=3Db is making errors on a particular= image, you can go to passes=3D1 accuracy and keep the nice feature that passes=3D= b with inside=3Dnnn will eliminate all of the lake areas with just their boundar= ies.

Another idea would be to make an option that uses passes=3Db behavior on = lakes but passes=3Dt behavior outside. ____________________________________________________________________ Get free e-mail and a permanent address at http://www.netaddress.com/?N=3D= 1 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Tim Wegner" Subject: (fractint) Re: last bug report Date: 24 May 1999 06:46:49 -0600 Paul wrote: Paul wrote: > Regarding "bug1", I interrupted it and hit tab.

It's a free- standing (and free) program that plots the beautiful attractors created by Scott Draves, which he describes as "cosmic recursive fractal flames". For further information on these images, refer to the online help file, and check Scott's Web site: http://www.cs.cmu.edu/~spot/flame.html The program is intended to use 24 or 32 bit "true color" graphics modes (16 million colors). But it also will work, with some limitations, in 8 bit modes (256 colors) and also 15 and 16 bit "high color" modes (the latter are not recommended). It will render images in resolutions up to 1600 x 1200. They can be saved to disk as GIF or TARGA files, depending on the graphics mode. The program uses 256-color palettes, which you can import from standard Fractint MAP files. The colors are blended by a filtering algorithm in true color modes. The parameter sets of individual images can be saved as small binary files to allow re-rendering of the images. The program, along with my other fractal programs, is available at my Web site. You also can find sample images there.

Right now its only available in the developer's version "mathtolerance=3D.05/.05 command. The first number controls the integer/float transition, and the second number controls the float/arbitrary precision transition. The default value of .05 means that the ratio between the exact and calculated width and height is between .95 and 1.05. A larger value than .05 (say .10) makes the tes= t looser so that the lower precision math is used longer. A value <=3D = 0 means the test is always failed and the higher precision math type is= used. A value >=3D 1 means that the test is always passed and the low= er precision math type is used. The automatic precision toggle is resolution dependent. The same imag= e may use float at 320x200 and arbitrary precision at 640x480. This is not a bug; it has to work this way. At a given magnification more pixels require more precision. There are other tests so even with mathtolerance=3D1/.05, eventually Fractint will have to use float. Th= e same is not true for mathtolerance=3D.05/1. If you keep zooming Fract= int will not rescue you; eventually you'll get a nasty error message and the corners will be lost."

One of the PARS was just illustrative of the area under question, so two of the PARs indicated bugs. Is this right? Upping the precision allowed bug1 to run as I mentioned before. The PARS Whrlbrot and Whrlwhrl ran fine with no changes. All the above were with the new developer executable. I used diskvideo. My working hypothesis is that you have found rare cases where the automatically-selected precision is too low. When this happens, just bump up the precision. We may find a better solution later, but there is a genuine tradeoff here. If the precision is bumped up for all fractals, arbitrary precision will be selected earlier, and all fractals will be slower. I'm not planning to do any more on this now, other than beef up the docs about the bfdigits command. I do have on my list revisiting precision issues at some point. What you should do on your end is confirm my solution.

That's supposed to be filled and if it weren't 80% of the passes=3Db spee= d savings would be lost for some fractals... > 2. Try to locate exact pixel when it happens. There is no specific pixel. It restarts if you interrupt it in a supposedly-resumable manner, such as color cycling or palette editing. Al= so make and then destroy a zoom box, go to a doodad window without changing anything. Only tab and F1 fail to trigger it on susceptible parameter set= s. It also occurs spontaneously (yes, with savetime turned off) on susceptib= le images in an unpredictable manner.

I shall perform an experiment later tonight; I shall bfdigits=3D16 a defa= ult Mandel image and see if it becomes buggy. Then we can be fairly certain i= t occurs when and only when it's using 16 digits precision. > I could do something really dumb like write each pixel corrdinate > to a file to see where it crashes. Useless. The restart is not specific to a pixel unlike the whrlwhrl hang.= It is caused by interrupting and resuming and by some occasional POM-depende= nt event behind the scenes. >> On a side note: What's the status of truecolor and synchronous orbits?= > truecolor - haven't done anything yet.

And no overlays etc. I recommend using DJGPP and Allegro to port a 32 bit version. Then you ca= n use Xwinallegro and WinAlleg to automatically compile simultaneously a Fracti= nt, Winfract, and Xfract of a given version.

I didn't mean to imply that a DOS version of fractint would disappear as it evolved to support natively more environments like Win32/Mac/BeOS/unix/etc. Support for 8088/80286 will disappear though as the DOS version will evolve to require a DPMI which means 386 or better. -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Phil McRevis Subject: Re: (fractint) Bug in Fractint 19.6 Date: 25 May 1999 11:17:16 -0600 In article <19990522040029.15273.qmail@nw178.netaddress.usa.net>, Paul Derbyshire writes: > Please submit a corrected version 19.7 on the Spanky website within 24 ho= > urs, > as this problem needs to be resolved urgently. ROTFLMAO! Please get real Paul. If the problem is *that* urgent, then download the source and fix it yourself. Fractint isn't a product for which you can "demand" bug fixes since you didn't purchase any such support agreement from anybody. -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: davides Subject: Re: (fractint) Bug in Fractint 19.6 Date: 25 May 1999 17:53:50 -0400 At 11:17 AM 5/25/1999 -0600, you wrote: > >In article <19990522040029.15273.qmail@nw178.netaddress.usa.net>, > Paul Derbyshire writes: > >Please submit a corrected version 19.7 on the Spanky website within 24 hours, as this problem needs to be resolved urgently. > >ROTFLMAO! > >Please get real Paul. Somehow I suspect that when Paul wrote the above he was doing so more as an attempt at some humor in order to bring a smile along with notification of a bug. It is the same kind of humor I have been accused of in the past, and just about as often met with the same kind of response.

Your tutorial on using colormaps is superb! I couldn't agree more with you about the effects of color on a fractal image. With the hope of getting some interesting palettes, I have made a couple of programs that generate algorithmic palettes that can be saved as Fractint map files. My most useful "find" is a four-range palette made from Bezier curves. Each range has a gradient that goes from dark to bright to dark, which gives a 3-d effect to many images. This type of palette is like the one you described in Example #5 of your web page tutorial: Example 5 is my favorite. It uses only 3 different bands of gradient color; orange, white and purple. But they are very wide bands and they work together to create a definite 3 dimensional look. I've used this type of palette for many of the images on my web site: www.clark.net/pub/jfield. There's also a gold and silver map that I find particularly effective for bringing out strong compositional lines or forms in an image. This map, which started as a two-range Bezier map and was tweaked into perfection by Michael Sargent, can be downloaded from the "gold and silver" page on my site. You probably hand-craft your own palettes, but if you or anyone would like to try the palette making programs, please let me know. I also have a GIF palette grabber. This program extracts the palette from the header of a GIF file and saves it as a Fractint MAP file. Most folks seem to be making true color fractals these days, so this program has limited usefulness. One can, of course, convert a JPEG into a GIF, and then grab the GIF palette, but the quantization that goes on behind the conversion scene makes what seems to be a disorderly GIF palette, when viewed as a gradient bar. For this situation, I have incorporated a palette smoothing algorithm developed by Scott Draves. The algorithm sorts a seemingly random palette into a series of short gradients with bright centers. This type of multi-mini-gradient palette is very effective for use with complex attractor programs, such as Michael Sargent's qsflame, and it also works well for many fractal images. Scott Draves, creator of the original flame program that Michael ported to Win9x/NT (with many improvements!), used his smoothing algorithm to create palettes from scanned images. --Jeff jfield@clark.net www.clark.net/pub/jfield 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Phil DiGiorgi" Subject: (fractint) Nifty freeware Date: 26 May 1999 20:03:13 -0400 Sorry, no fractal content, but I thought this little program might be of interest to the subscribers to this list.

Hi !
 
1 or 2 years ago I found (on the = Web) a map=20 pointing at nice locations where to zoom in a Mand.
 
Some area are poor of beautifull = things, other=20 have plenty !!! Spendig zooming time in a poor area is frustrating ..=20
 
Is there such a map somewhere ? =
 
Many thanks

Producing a fractal is a complex process even to= a fast computer. Each figure requires a lot of calculations, and those take time. The deeper you go, t= he slowest the process will be. Keep the image relatively small (between 300x300 and 600x600, but not sma= ller or you won't discern the details) while searching for the area that attracks your creative self. O= nce you finish working with it, change to a big resolution for the final file. Regularly it will take just a few minutes to calculate a fractal, but som= etimes it could take as long as several hours or even days (and even a lot more). That depends on the com= plexity of the fractal and the number of iterations you choose. A small change in the parameters - the values of each variable - will res= ult in an entirely different image. Once you find something interesting, save it or write the values on paper= or to a text file (using NOTEPAD, for example). Otherwise, you won't probably be able to return to= that same spot again. You could end up with two dozen fractals before finishing a single image, but= you won't regret it if suddenly an unexpected and unwelcome error happens. Most of the fractal generators I know produce a parameter's file whenever= they save a bitmap (that's the case with all of Ferguson's generators). Some others (FractInt among = them) store that information in the same image's file; thus, be sure to keep an unadulterated copy of the= original file if you plan to alter the fractal in a graphics editor later. INFI and Kaos Rhei won't do any o= f that automatically, so get used to do it manually. For INFI, create a new bookmark for every image you co= me up with; for Kaos Rhei, choose "Save Parameters" from the FILE menu item. It's also practically impossible to produce two identical images except w= hen using the same, and only the same, parameters. So keep those files in a save place. They are the t= he only way you have to reproduce an image (if need be) and could be a proof of authorship. It is absolutely probable that you won't know what an image will look lik= e beforehand. You'll be exploring an imaginary and never-ending world, searching for new vistas t= o bring to the real one. There are certain basic features that are easy to remember and recognize,= but while you "travel" along the Mandelbrot regions, for example, new patterns never seeing before wil= l come into view. That's part of the thrill that attracts us to fractal art. If you have been zooming in a region for a while, chances are that you ha= ve noticed that several features look whashed out, with dark patches and without any detail. It's= just that you are too deep into the figure at "low resolution". Adjust the number of iterations to a high= er value and the small Mandelbrots, ridges, spirals, smoothness and spikes will return to view. It's not possible to explore the whole Mandelbrot set in a lifetime, let = along all other fractal types out there. Although you can see many fractal images in a lot of publications,= web sites and other products (including nature), the chances of getting an original composition are hi= gh. Most fractal generators are capable of applying filters such as stalks, a= tan, strands and bubbles, to an image. Those are also mathematical expressions that enhance or adds featu= res to these intriguing shapes. After getting the figure concentrate on coloring it. That will make the d= ifference between a regular image and an artwork. The coloring method will depend on the fractal gene= rator you are using. Some use palettes in which you are free to select the colors to be used; other= s use color controls, and you just have to move the sliders up or down, left to right, until you get th= e combination that fits your taste; some use algorithms to give the tones to each pixel; while others = are based on predefined color maps which colors can be rotated in order to change their hues. Feel free to apply post-processing techniques to the resulting images. Wh= ile some purists will say they hurt the natural figure (what certainly is true), they will add to the cr= eative process, increasing the artistic outcome. Study, at least briefly, the mathematics behind the images. You will disc= over you don't need to be a genius to understand the basic concepts. The sole process of generating a= figure will help you to get some clues that could later turn into wonders. Now go create some fractal art. Bob "When Will This Zoom-in End?" Margolis = .

I have an idea that this procedure might lead to self similar areas, which might not be desirable. After first implementig arbitrary precision, I tried to "fish" for a fractal in very deep water (e.g. high magnification). I did it by using viewwindows mode and letting just a few pixels develop in solid guessing mode. Where pixels had different colors, I figured it was safe to zoom. What I was trying to avoid was a solid area with no structure. The problem was that arbitrary precision is slow, so I was trying to see where to zoom by generating very few pixels. When I was done, I let the whole fractal calculate. I wondered if I had set some kind of a record, since the magnification was something like 10^900, and the fracta;l looked quite interesting. But alas, something looked wrong. The fractal looked familiar. In fact the fractal was identical (except for rotation) to a fractal generated at the same place but with a very modest magnification. From my very limited experience, it seems to me that most strategies from zooming in to very deep magnifications are liekely to fall into "whirlpools of self similarity" where nothing new is found. One strategy to avoid this is to follow a descreasing sequence of migit Mandelbrots. I don't know how to prove this, but it seems apparent from experimentation that midgits are not self-similar, quite the contrary: as one zooms deeper, the patters surrounding the midgits change. Questions: 1. Is it true that zooms following sequences of smaller and smaller midgits never fall into self-similarity 2. Are there other strategies for zooming to great depths that result in different images as one goes deeper.

In a sense, all whirlpools are illusory. The M-set is *never* quite self-similar. Example: Start with a seahorse and generate an image of the= spiral. Save this in a par file. Zoom the outer curve of the spiral and f= ind a double spiral which hides a midget. Now from the original spiral, zoom the center of the spiral two or three times. Whirlpool? Maybe not. Zoom a part of spiral arm and find a double spiral. The double spiral is not the same! It has many more turns. But to see anything interesting deep in the spiral you couldn't find near= the surface, you need to move away from the middle eventually and aim for whe= re there is a midget. The moral of this story is, the stuff around midgets in a "whirlpool" cha= nges the deeper you go, usually by wrapping around more times in some way. > One strategy to avoid this is to follow a descreasing sequence of = > migit Mandelbrots. > I don't know how to prove this, but it seems apparent from > experimentation that midgits are not self-similar, quite the contrary: > as one zooms deeper, the patters surrounding the midgits change. Yep. Every mini Mandelbrot has a characteristic filament that attaches to= it. As you zoom up mini Mandelbrots you accrete more filament types. > 1. Is it true that zooms following sequences of smaller and smaller = > midgits never fall into self-similarity Yep. Although things can just keep getting hairy. > 2. Are there other strategies for zooming to great depths that result = > in different images as one goes deeper. Yep. There are two basic strategies. One is to zoom and generally hang ar= ound mini Mandelbrots; the other is to zoom into clefts between buds, where yo= u can accumulate more kinds of spirals or seahorse arms or scepters. There's a third, more advanced strategy, which is to mix the two abopve strategies. As for strategy 1, I must elaborate. You can zoom to the actual mini Mandelbrot and explore its clefts and primary dendrites. You can zoom ver= y near it and explore attached filaments for their mini Julias. There are infinitely many variations here. For instance you can zoom at a midget an= d then a midget of the first's primary dendrites, then find an interesting = area of the micro Mandelbrot. Find a dendrite, which will have filaments assoc= iated with the micro. Zoom one of the filaments. It has mini Julias and more filaments, these associated with the mini. Zoom this tertiary filament an= d there are more embedded Julias... which are associated with the mini, not= the micro. These mini Julias have, embedded in them ... mini Julias of a diff= erent type, those characteristic of the micro. Yikes! Instead, you can stop far out from the mini, where there are only two or = four or eight or sixteen repeated filaments. Then attack one of these. You get= "dumbbells" or other shapes. Zoom a 3-armed spiral for instance. One arm = goes to the mother set, two terminate in bulbs. Zoom an arm and find a doubled= spiral. Instead of aiming for the central, probably still invisibly small= mini, attack one of the double spiral's arms. Pick one that terminates. F= ind a doubling, and you'll see that each spiral in the doubled spiral has one a= rm to the central join where a mini lurks and one arm that terminates and a thi= rd arm that passes through another joining on the way to the mother set. Now= attack the remaining terminating arm... As for locating the mini, it makes a difference where it is on a filament= , or how deep in a whirlpool. When exploring a mini Julia, you can find a mini in the center, but you c= an also attack the mini Julia's other structures... spirals, seahorse eyes, dendrites, or whatever. ____________________________________________________________________ Get free e-mail and a permanent address at http://www.netaddress.com/?N=3D= 1 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Genealogy1@aol.com Subject: (fractint) A Julia type...

I think what you're seeing here is the period doubling phenomenon that one would observe by following the midgets that are centered on the real line. The dynamics of M on the real line are the same as the dynamics of the bifurcation plots. A colleague once wrote a program that superimposed the two and you can see that the bifurcation plot goes through its first bifurcation at the point where the circle joins the main cardiod. The next bifurcation happens at the place where the midget centered on the real line touches the circle, and so-on. If one used this as a zooming strategy, you'd find that the midgets keep reappearing, but that the number of tendrils leading into the midgets follow a period doubling progression. Aliasing soon takes over after several zooms :-), preventing you from seeing all the tendrils. -- Legalize Adulthood! ``Ain't it funny that they all fire the pistol, at the wrong end of the race?''--PDBT legalize@xmission.com 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@phoenix.net Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Ricardo M.

Date: 31 May 1999 22:11:43 MDT Attached below are two source files, which are fairly short. The first, batchm.cc, is a simple C++ source, fully ANSI (I think, if you= find an incompatibility let me know), which generates a Mandelbrot image from command line parameters (center, mag, and a few more) using either 1 pass= , tesseral, or guessing. It's been tested (in all 3 algorithms, with severa= l classic seahorse valley images) and works. The output is a 3 megabyte "iter.dat" file. This file consists of a 1024x768 array of unsigned 32-bi= t integer values, which are iteration values, arrayed first across then dow= n. This is raw iteration data, not a meaningful image file format, to be col= ored externally. It is also not compressed, so it always takes up exactly 3 megabytes. (4 byte integer times 1024 times 768 is 4 times 1024 times (10= 24 * 3/4)) bytes ... or three quarters of 4*1024*1024, which is three quarters= of 4 megs, which is 3 megs.) A future revision will allow the output filename to be changed from the default with a command line parameter and will nix a slight bug. Known bugs: Just one. The occasional image is generated with a few pixels= saved with maxiter+1 as the value. I am not certain how this happens and = plan to investigate. As a result, the maximum value in the iters.dat file isn'= t always the value you color black to fill the lake. The program uses long double arithmetic (whose precision depends on the machine architecture compiled on). It should be as capable of zooming as Fractint sans arbitrary precision (e.g. Fractint 18.21 or Winfract). It only does Mandelbrots. And it only does them plainly, with the lake fi= lled in as the set maxiter value. There is periodicity checking by the way. The algorithm is a variant of a= classic one and probably similar to Fractint's. The second program is srenderm.cc. It requires the Allegro graphics libra= ry or something compatible. It should work with winalleg, dos allegro, and x wi= ndows allegro. It reads "iter.dat" in the format output by batchm and displays = it onscreen in the highest-bit-depth 1024x768 video mode it can autodetect. = (A high-color, i.e. 15 or more bits, 1024x768 mode *must* be available.) The iterations are mapped between the minimum and maximum iteration to a simple golden color scheme. The M-set itself is black (unless the afore-mentioned batchm bug struck, in which case it will be white with scattered black pixels adjoining). A future revision will allow specifying the input file, saving the output= in =2Epcx format (to any input filename), optionally doing a render and save= without invoking graphics, and allow editing of color scheme, loading, an= d saving in a manner resembling Ultra Fractal. I may also include an option= for rendering to a greyscale, applying some log function to the input in the process, and outputting a greyscale TGA of the kind ray tracers can use f= or height-fields. I may also develop a third program, pure ANSI with no special libraries needed, for converting the batchm output into a triangle mesh of chosen l= evel of detail (up to 1024x768x2 triangles) saved in a format ray tracers can = use. Both programs handle errors rather ungracefully, by immediately terminati= ng with a terse but meaningful error message. (Some bug with killing the gfx= mode seems to suppress these with srenderm, which I shall fix soon.) --- Here is the batchm.cc file, with comments explaining command line options= and some of the internals. // batchm.cc // (c) 1999 PGD. Open Source. // Very simple batch Mandelbrot program. // Types: just Mandelbrot. // Algorithms: just periodicity checking and either 1-pass, tesseral, or = solid guessing. // Options: 1, t, or g for algorithm, and option to determine "iteration resolution". // Interface: command line. // Command line consists of center and mag (long doubles), iteration resolution control, and optional switches. // Examples: foo.exe (basic Mandelbrot) // foo.exe -.75 0 10 (seahorse valley zoom) // foo.exe -.75 0 10 5000 (Maxiter 5000 instead of default 2000) // foo.exe -.75 0 10 5000 30 (Now iterations resolved individually = from 1 to 30, to nearest even number from 31 to 90, etc.) // foo.exe [real-center-coordinate] [imag-center-coordinate] [magnificati= on] [iteration-resolution] [switches] // Anything before the first switch is regarded as the first, first and second, first, second, and third, or first, second, third, // and fourth of the numerical parameters. // Switches: /1, /t, /g for algorithm. // Output: Either an iter.dat file or an error message from the following= : // * Invalid switch Command line has an unrecognized switch. // * Extra parameter Command line has an extra non-switch item. // * Ill-formed parameter Command line has a parameter that is not a num= ber or else is not an integer // but should be an integer. // * Various libc file I/O errors to do with problems with writing iter.d= at // On-screen a successful run will display a progress indicator, outputin= g pixels-done/pixels-in-image every thousand pixels. // Format of iter.dat: across-then-down 1024x768 array of iter values. Ea= ch value is a big-endian 32-bit integer. // File size is thus 3 megabytes ... post-process it and then archive/del= ete! // Defaults: passes=3D1, center at (0, 0), magnification 1 (which means i= mage is 4 units by 3), maxiter 2000, and // iterations resolved as follows: individual -- 1 through 50. Nearest ev= en -- 51 through 150 (as 52, 54, ... , 150). // Nearest multiple of 4 -- 151 through 350, etc. // Math used: long doubles everywhere. // For batchfile use, the errorlevels returned are: // 0 -- Normal exit. // 1 -- Incorrect cmdline. // 2 -- File I/O error with output. // 3 -- Miscellaneous error. // 255 (-1) -- Crashed (should not happen). // Compilation: // This is portable ANSI C++.
