FOTD 09-05-07 (Imaginary Interlude [7])
by Jim Muth 09 May '07

09 May '07

FOTD -- May 09, 2007 (Rating 7) Fractal visionaries and enthusiasts: Starting with today's image the calculation time included in the parameter file will be true on a P4-2000 mhz unit. I will also eliminate the trivial hundredths of a second from the calcula- tion time. Today's lively image came about when I combined 5 negative parts of Z^(-1.1) with one negative part of Z^(-5.5) and added 1/C, to create a parent fractal of truly humongous size. This monumental fractal has a rather modest 'fan'. Today's image is located in a patch of interesting debris at the northern edge of this 'fan'. I named the image "Imaginary Interlude", which might be the name of a romance movie, but actually is the name of a fractal. I rated it at a 7, which seems about right for such a fractal. The calculation time of 1-3/4 minutes would be about 8 minutes on the old P200 computer. This time is within reason. Those with over-qualified machines may view the image pre-calculated on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Absolutely perfect weather prevailed again here at Fractal Central on Tuesday, with cloudless skies, light winds and a temperature of 75F 24C. The fractal cats must have agreed, for they spent several hours in the window, watching the birds and squirrels. My day was pleasantly busy. The next FOTD will appear in 24 hours. Until then, take care, and fractals are all in the mind.

FOTD 08-05-07 (The Great Mystery [8])
by Jim Muth 08 May '07

08 May '07

FOTD -- May 08, 2007 (Rating 8) Fractal visionaries and enthusiasts: I was very busy on Monday, installing a new computer in Fractal Central, so today's discussion will be very brief. When the new machine is up and running, the old one, a P4-2000, will become the fractal-dedicated unit. The current fractal machine, an ancient P200, will go into a well-deserved stand-by mode. Today's image lies in the fractal that results when 4 negative parts of Z^(-1.4142) are combined with 1 negative part of Z^(-5.6568), which not accidentally happens to equal 4*(sqrt(2)). Since I think the image is quite good considering the brief time spent in finding it, I felt justified in rating it at an 8. The biggest mystery is why I named it "The Great Mystery". The calculation time of 6-1/2 minutes is brief enough to offend no one. But an even quicker way of seeing the image is to visit the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and view it there. The weather on Monday here at Fractal Central was absolutely perfect. We enjoyed cloudless skies, light winds and a tempera- ture of 72F 22C, while the fractal cats enjoyed dashing up and down the long hallway. My day was quite busy setting up the new computer. The next FOTD will appear in 24 hours. Until then, take care, and are numbers subjective or objective?

. 60502023 par by Lee Skinner loox interesting; the parent mutantbrot (mag=0.66) is the craziest most f'd-up one I've seen in recent memory. also if you continue zooming in there is a nice infinite spiral. I will try to do a zoom-in and beyond animation, but I must change that color map .......... CYa .

FOTD 07-05-07 (Iteration Quest [7])
by Jim Muth 07 May '07

07 May '07

FOTD -- May 07, 2007 (Rating 7) Fractal visionaries and enthusiasts: Today's bright, lacy image lies in the parent fractal that appears when the formula Z^sqrt(2)+C is iterated 52 levels up the topless and bottomless complex logarithmic ladder. This parent reminds me of a distorted Mandelbrot set with its west side facing southeast. Despite its odd shape, the open area at the center is a true midget, though there is certainly very little of a quadratic nature about it. Today's image is located in the northeast branch of what might be called Seahorse Valley, since it cuts off a very prominent period-2 bud. When I saw the image I rated at a 7 almost immediately. I have no logical explanation to offer for the name I gave the image -- "Iteration Quest". It sounds kind of interesting though, and might attract a few viewers. And speaking of attracting viewers, when I checked the FOTD web site today, I couldn't help but notice all the nameless images I have been posting for the past several months. Without names, these images are not going to attract many viewers. So from now on, regardless of how much or how little effort I put into the FOTD fractals, I will give every one both a name and a rating. Today's image takes over 41 minutes to calculate on my P200 machine. (There is no more P133 machine; it gave up the iteration last Thursday.) The 41-minute wait may be avoided by visiting the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the completed image there. Lots of sun and an only slightly cooler temperature of 66F 19C made Sunday a day to remember here at Fractal Central. The fractal cats may not remember the weather, but they will remember the dove that landed right outside their window. My day was unusually pleasant. Too bad every day can't be the same. The next FOTD will appear in 24 hours. Until then, take care, and don't dare turn a Klein bottle inside-out.

################################################################ Jim, In your FOTD -- May 06, 2007 you describe the parent fractal as: > The parent fractal is a > string of four north-south oriented large bays, with the south- > ernmost bay showing the strongest Mandeloid characteristics. When I calculate the parent fractal of this FOTD I do not see what you describe. I calculate the parent fractal as follows: After I calculate your FOTD I calculate its parent fractal by hitting <Z> <F6> and setting 0,0,1,1,0,0. After letting this fractal render I then zoom out as much as is needed to get the entire parent fractal to fit onto the screen. I rotate the parent fractal to get its longer axis horizontal. I also set the Log Palette (logmap) parameter on the <X> screen to zero. I have put the .PAR file I created for the parent fractal in question below. Any comments as to why I get a parent fractal that does not match your description would be appreciated. - Hal Lane ######################### # hallane(a)earthlink.net # ######################### START PARAMETER FILE======================================= FOTD-May6'07parent { ; Hal Lane May 06,'07 11:50 P400 1024x768 ; Parent fractal of Jim Muth's FOTD ; for May 6th, 2007. reset=2004 type=formula formulafile=_m.frm formulaname=mandautocritinz function=recip passes=1 center-mag=1.90028/-0.824587/0.1536318/1/90/3.885780586\ 18804789e-016 params=-6/-1.17/-0.8/-7.4/0/0/0/0 float=y maxiter=2000 inside=zmag periodicity=10 sound=off colors=000<9>00000000000000001000000Z00R00d50lA0lE0uH0j\ L0kM3jQ7ETA0VC0R80Q70<2>J11H07F0CE0FA0L80O70T50X30d30k1\ 5q1Mx1Tz8XxF`sMWlgVg_TbfEXlFRsKMyPFzUAzZ5zc0zf0zcazZ_zU\ Y<2>oFTkHRfER`LQW2ObfM<2>VyHTzHOzF<3>bzFfzFjzEnzErzEwzE\ zzEwzEtzHqzLozMmzQkzRizV<3>azd_zfYxb<3>QqQOoMMlJKkFIiC<\ 2>C_1AX08T3AR7COACMCELFFHJHJLHLOJLRLMTMMXMO_OQaQQdRRgRT\ iQYgQafQffQigQlgQqgQugQxiXqoalufgykazoXzvRzzLz<2>z5zzAz\ <2>yLzvOzqTznXxk_ufbqbfnYklVnkRqgMufJxdFzbJqXMgQO_JRQCV\ F5X70Y87Y8C_8J_8O_8Va8_a8daAkbAobAvbAzdAzdAzdAzYEzRFzLJ\ zELy7Ov0Qq0Rn0HT078000000000103808E0EL0JR0MY0Rd0Xi0ao0f\ v0kz0oz0su3vi7xXAzLEzFHvCLq8Ol3Rg0Vb0YX<2>0gH0kC0n80q71\ u5UfhFz0<3>fz0lz0sz0yz05z08z3CzAEzFHzMLzTMzYQzdTzkVzoYz\ v_zz<2>5zV0zJ0z80zO0za0zo0zz0zz0zu0z_0zF000 } frm:MandAutoCritInZ {; Jim Muth a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=1/f, h=1/d, j=1/(f-b), z=(((-a*b*g*h)^j)+(p4)), k=real(p3)+1, l=imag(p3)+100, c=fn1(pixel): z=k*((a*(z^b))+(d*(z^f)))+c, |z| < l } END PARAMETER FILE========================================= ########################################################### No virus found in this outgoing message.

FOTD 06-05-07 (The Creation of Chaos [7])
by Jim Muth 06 May '07

06 May '07

FOTD -- May 06, 2007 (Rating 7) Fractal visionaries and enthusiasts: Today's image shows just a few of the things that happen when 6.0 negative parts of Z^(-1.17) are combined with 0.8 negative part of Z^(-7.4) and (1/C) is added. The parent fractal is a string of four north-south oriented large bays, with the south- ernmost bay showing the strongest Mandeloid characteristics. Today's scene is located deep in a split-apart fractal ring just southeast of the southernmost bay. After some thought, the phrase "The Creation of Chaos" came into my mind, and this is what I named the image. I can give no real connection between the image and its name, but the name sounds rather poetic. I rated the notably average image at a 7. Its starburst effect earns the rating. But the slow calculation time of 37 minutes on my old P200 unit is a definite drawback. I recommend fractal fans avoid this drawback by viewing the completed pre-calculated image on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Absolutely perfect spring weather prevailed here at Fractal Central on Saturday, with unbroken sun, light winds and a temperature of 73F 23C. The fractal cats glanced out the window once or twice before returning to the large paper bag they were in the process of destroying. My day was pleasant, though I must admit that I feel a twinge of nostalgia when I visit Old Fractal Central and see the old fractal cats who are still there, and remember the neighborhood as it was 30 years ago. But even though we mere humans don't quite know what time is, it goes ineluctably onward, and the next FOTD is due in 24 hours. Right now, I'll give over a 99-percent probability that it will actually appear on schedule. Until then, take care, and keep on the fractal side of the street.

Fractal fans and visionaries: I am back at Old Fractal Central. Unfortunately, the ancient and ailing P133 computer that I was using down at Old Fractal Central finally crashed for good Thursday afternoon. Its end was overdue, but it took the FOTD's for May 4 and 5 with it. The next FOTD will be the one for May 6. It will appear on schedule. Jim Muth

http://web.ukonline.co.uk/members/robin.b2/olig/wisharc.htm That looks like *a* wishlist archive, but my wishes from after 1999 aren't on it. Is there another, later one? Here are a few wishes of mine, all for L-systems: 1. Vector output as an option, e.g. dxf. L-systems ARE linear-based fractals, after all. Vector output would allow exactness in L-systems rendering - something sorely lacking once screen details come anywhere close to maximum. I do already have a "mutant" version of Fractint with this capability, kindly sent to me by Robin Bussell. It works only in mono, no colour output, but has given me much enjoyment. I would suggest 256-colour output at least. (This option could even be included for tesseral and outline output types of bitmap fractals! Both allowing filled closed shapes. Think of that.) 2. If vector output is enabled, then other possibilities beg for implementation. Joining of line segments' endpoints to make closed curves which can be filled in a programme like CorelDraw is one. Removal of endpoints of adjacent line segments which are on the same straight line is another - a way of hugely reducing file memory size. Reducing of "layers" of redundant line segments after each iteration is a third. This is unnecessary in bitmap output - drawing a line on top of itself many times has no effect on the memory size of the file. But in Vector output, it does, of course, add to file size, possibly multiplying size many times over. There are many L-systems (like Hanmer Tiles) which have great numbers of layered line segments; keeping them as small as possible in vector output would be of great benefit. Line segment elimination could be done after each iteration has been calculated, before the follownig iteration - this slows down calculation, of course, but computers ARE getting faster all the time... 3. The possibility of line segments being curved instead of only straight! One could select from a list of curve equations, and the list could be added to as well. This would really transform L-systems. 4. Removal of some limitations (I've mentioned this before; not the highest priority, but not too difficult to implement either I think, once Fractint migrates from DOS). Namely, *.l file limit of 2000 entries (Hanmer Tiles are infinite in number...), and L-system programming string limit of 256 characters (I think that's the current limit) (Hanmer Tile programming can lead to very long strings). 5. Some kind of randomisation factor, user-specified as a percentage or range. This could vary either line length, or angle, or both, and lead to more natural-looking L-systems for rendering of plants, etc. Perhaps if a certain specific randomisation is attractive to the user, it could be saved and re-used. 6. IF-THEN programming. There are all sorts of possibilities for this, most of which I probably am not informed enough to imagine. Again, they would greatly extend L-systems programming. 7. 3d is perhaps not more than a dream or a distant goal, if anything. Tony Hanmer
