SherLok Merfy and Hiram Berry have recently posted some pars. Unfortunately I (and presumably others on this list) cannot generate them as posted because the pars contain reference to non-standard map names. Whereas chroma.map is included in the Fractint distribution files, kayos.map and sloshdun.map are not. Anybody can name a color map, but others will not have access to the map file. The way to get around this is to put recordcolors=Y into your sstools.ini file, so that the colors will get recorded into the par entry submitted for posting. I would be grateful if SherLok and Hiram would repost their pars with the colors. Otherwise, I can generate the pars as already posted with default.map, but I'm sure they won't look as well as the images on the machines of the original artists! Thanks. Lee

Certainly, Lee. Thanks for the admonition against posting attachments; I really wasn't aware of it, but I fully understand the rationale: I left my virus-scanner going last night, came back in the morning to find... in spite of my fairly high level of vigilance a malicious spammer had gotten 2 copies of the mydoom.f worm onto my computer disguised as, of all things, a .png file! I notice that the recordcolors representation is _much_ more concise than the .map file too. So, I've included the revised pars later in the body of this message, as well as one additional one that uses the linear Julibrot slicing formula, called "ClubmossMorass" that illustrates the extreme disorder that can found in some of the slices. Also, I mentioned the possibility of doing nonlinear slices the Julibrot Set and then mapping the parameter of variation on those surfaces to the complex plane to view it, but didn't give any examples. Here are two formulae which do that, though I haven't optimized them to be especially intuitive with regard to the subset of the space they're slicing. The first one slices on a spherical surface, while the second one is a slight modification of the first to slice a Lisajous surface: /***********************FRMS BEGIN******************************************/ JulibrotSlice1+1i { ; a nonlinear slice of the Julibrot: ; the surface of the sphere passing through C2 origin ((0+0i),(0+0i)) ; with radius p1 is rotated about the origin by complex angle p2 and ; then offset by (p3,p4) so that its surface passes through the C2 ; position {z0=p3,C=p4}. The parameter of variation represented by ; "pixel" then maps points on the spherical slice to the screen. ; Varying p2 then rotates the sphere around the anchor point (p3,p4) ; while varying p1 expands or contracts the bubble while maintaining ; the anchor point on the bubble. ismand = true r = p1 ; complex radius of sphere which is the slice cosphi = cos(p2) ; sphere will be rotated by p2 sinphi = sin(p2) k = pixel ; complex angular parameter of variation on sphere surface z0 = r*(cos(k)-1), c0 = r*sin(k) z = cosphi * z0 - sinphi * c0 + p3 c = sinphi * z0 + cosphi * c0 + p4 lim = 9 : z = sqr(z) + c |z| <= lim } JulibrotSlice1+2i { ; generalization of JBS1+1i spherical slice into ; a Lisajous surface slice in C2{z0,c} parameterized ; by {cos(k),sin(p5*k)}, ie. p5 contains the harmonic ; multiple. As p1 shrinks pseudotiling should occur. ismand = true r = p1 ; scale factor, not really "radius" anymore cosphi = cos(p2) sinphi = sin(p2) k = pixel ; parameter of variation z0 = r*(cos(k)-1), c0 = r*sin(p5*k) z = cosphi * z0 - sinphi * c0 + p3 c = sinphi * z0 + cosphi * c0 + p4 lim = 9 : z = sqr(z) + c |z| <= lim } /****************************FRMS END***************************************/ Concerning the following pars, JBS1+1i_init (the nearly M-set figure with oversized buds on the 2^n spike) and JBS1+2i_init (the Rorschach-like double blot) are just for starting an exploration into these slices. The pair {"DisconnectDemo","TendrilDisconnect"} illustrates the point I tried to make in my previous post about the breaking of connectedness, in this case very subtly, in the oblique Julibrot slices: the first par shows a large scale view of what looks at that vantage to be an intact M-set with its tendrils connected and with minimal distortion; the second par shows a closeup of the major minibrot on the spike. In contrast, it looks more like the outline of Antarctica than a minibrot, and there are very defined breaks on its subsidiary tendrils, which hook at the break almost as if there were a physical repulsion force involved. Finally, there is the series {"FountainOfWraiths","MutatedFntOWraiths","ThrowingStarSpiral"} The first one is an overview of a Lisajous surface slice illustrating many design themes hybridized in one image: Julialike here, Mandelbrotlike there, disconnected recursively selfsimilarity in one region, a monolithic bulk with a border like torn paper in another, with short transitions between dissimilar themes. I believe this is caused by the often-changing curvature of the surface in the Julibrot space. The second par show what happens to this region when a modest reduction in the imaginary component of one of the parameters is made: overwhelming Mandelbrot character asserts itself and most of the unconnected satellites either reconnect or move closer to the main mass. And yet... the third par of the trio is just a magnification of one of the satellites in the second par-- no changing the params-- even on the Mandelbrotlike slice here is a region with fully Julia set character: Extreme symmetry, recursive self similarity, etc. These pars follow: /********************************PARS BEGIN**********************************/ TumbleweedJBS { ;

I don't see a likely problem, there. Of all the places where a virus scanner is likely to make a false hit, it's a compressed graphics file or an encrypted file. You don't execute .png files, so it can't spread from there. Now, you might say that it isn't required to execute OPCODES, but portable network graphics are not a programming language of any kind. To state a limit on Java that didn't turn out to be so fundamental, it certainly doesn't hav access to the filesystem. There aren't any perfect filters or virus scanners. Virus scanners routinely hit BO2K, but that's a source-forge project for a product that competes with Back Office, so I'm pretty sure that politics gets into the virus scanning scene, too.

I think you're probably right in this case; as time goes on the viruses get more complex, the search strings and algorithms for the scanners escalate in response, and eventually the "million monkeys on a million typewriters" effect must intersect in a lot of false positives. You don't execute .png files, so it can't spread from there. Yes, that's reassuring, it may be also be an artifact of the "infection" process, ie. not intentional-- perhaps at some other stage the worm copies itself into random files, some of which are distributed unknowingly-- most would be nonvirulent in that form. Now, you might say that it isn't required to execute OPCODES, but portable network graphics are not a programming language of any kind. To state a limit on Java that didn't turn out to be so fundamental, it certainly doesn't hav access to the filesystem. PNG isn't, but some of the information encoded in an image could be a program, ie. I think they call it steganography. Like you I don't _think_ that poses any kind of real threat, since the malicious program would have to be reconstituted by some other process to be dangerous, but it is interesting from the standpoint of overall information transfer dynamics. You might also say that a file enumerating the base pair sequence of say, the SARS virus, which I believe you can download from a publicly accessible database, is just the textual result of experimental observation and therefore not a program either, but I would disagree with such a statement.

On Mon, 1 Mar 2004, Hiram Berry wrote in a thread that diverged from colour maps: I imajin that I don't know ten percent of the optimization difficulties in this topic, but steganography is a bit distant. As I see it, the search strings for viruses are probably kept short in the interests of keeping the total size of the database to a limit, but single bytes will probably collide within 256 bytes of a format that naturally has a flat distribution, two bytes will tend to collide within 64k, and even four bytes of search string will probably collide within 4Gigabytes of high-entropy data. So, you can see that in this branch of Computing Science, entropy isn't entirely your friend. And it's hardly the case that anti-virals are at odds with crypto, because that's what makes authenticating the database practical. Such practicalities are not likely to be within any line of thought that will yield a fractint method, though. I expect that the better anti-viral programs use search strings primarily to hit on possibilities, then they resort to more elaborate descriptions of how to verify that a virus is a threat and clean a virus file. I've read a description of boot-sector viruses that describes how they will also insulate themselves from detection in memory and on disk. That is they trap requests to read that part of your disk or RAM. (It's far more reliable to do that in protected mode, where you hav no other way of restricting DOS programs to a window). I wouldn't know where to go from here, but perhaps I could get a physical map of your hard-drive's entropy by comparing hits between it and a pseudo-random number jenerator. The hard part of a trick like that would be adapting the routines to FRACTINT's zooming (and convincing newbies that I wasn't compressing their hard-drive for display to the world in steganographic form). My guess is that I would hav the length of the sample as a parameter to adapt to the sheer size of your hard-drive. It was a stretch, but I found the link to steganography.

Thanks for the tip, Paul. _________ Hiram Berry

I would be grateful if SherLok and Hiram would repost their pars with the colors. Otherwise, I can generate the pars as already posted with default.map, but I'm sure they won't look as well as the images on the machines of the original artists!
Not really, kayos.map is just a tweaked graymap. It is also just intermediary results in my search for excellent fractals that look like suits for cards.

Oh, that explains the name of your .frm "Club_Lambda". Rather than just searching for them, have you considered the possibility of finding excellent fractals with circles in them? Those should be a lot easier to find than shapes like clubs or spades . Then you could morph the appropriate region of the domain complex plane (the "pixel" variable in the .frms) into the suit shapes with conformal mapping. I think I saw you used the "INVERT" command in one of your pars earlier; that's a simple example of a similar process. Around 90 years ago, before _any_ automated calculation was available, Joukowski came up with the process of conformal mapping to warp the (analytically known) velocity field around a circle into the velocity field around a class of (actually quite serviceable) airfoil shapes and still satisfy the flow conditions; people later extended the idea to arbitrary shapes on the complex plane. I don't see any reason you couldn't use the same technique on fractal viewing planes. Some information on conformal mapping is here: http://math.fullerton.edu/mathews/c2003/ConformalMappingBib/Links/ConformalM... BTW, I noticed that "Club_Lambda" uses two complex process parameters just like the Julia/Mandelbrot duality. It could just as easily be extended into the "4 dimensional" format that Jim is using for the Julibrot. (I consider it to be really (or maybe imaginatively) to be 2 dimensional, but by his silence he apparently disagrees, which is okay) In any event the extra dimensions would give you a much wider space to search for your ideal suit shapes. Hopefully being helpful, Hiram Berry

Thanks, but I don't think I'll need the conformational mapping. I already hav _adequate_ fractals for the purpose of card suits that would be recognizable. But I _want_ ones that look good with outside=atan for the black and white, either that or ones that hav lots of gradient shading like the inversion of the classic that shows me that passes=d is the only way to go.
