; Date: Sun, 18 Aug 2002 11:28:32 -0400 ; From: Jim Muth ; Subject: [Fractint] FOTD 18-08-02 (Iterative Teardrops [6]) ; Id: <1.5.4.16.20020818112923.299f91c2@pop.mindspring.com> ; --------- ; FOTD -- (Rating 6) ; ; Fractal visionaries and enthusiasts: ; ; It's Sunday mid-morning here at Fractal Central, and all is ; well. I have just finished emptying my e-mail box of two large ; undeliverable e-mails that were returned to me. This is well ; enough, except for the fact that I never sent the letters in the ; first place. It's probably another virus, and a clever one at ; that -- one that works like sending a letter via normal mail ; with no postage and writing the name of the address you want it ; delivered to in the 'from' space. Then when the post office ; 'returns' the letter for lack of postage, they are actually ; delivering it. ; ; I also feel a bit cruel about failing to reply to Baerbel's ; request for information about unsubscribing from the Fractint ; list. But it's a bit amusing to see such a request (from ; someone who already knew how to subscribe) appear three lines ; below the unsubscribe information in the letter's header. ; ; As for today's fractal, (which I have rated at a harmless 6), ; it's a scene in the fractal that results when 0.01 part of Z^2 ; is added to Z^(-2), and (1/C) is added to the combination, then ; the whole thing is iterated with a bailout radius of 100. That ; 0.01 part of Z^2 is not much, but it makes a world of difference ; in the final fractal. ; ; The parent fractal, which is enclosed in a circle, looks ; surprisingly like a fractal planet. Changing the logmap of ; today's image to 0 and doing about 10 out-zooms will reveal this ; planet in its full glory. As is the case with most fractals ; that contain a negative exponent of Z, the bailout radius has a ; great effect on the appearance of the fractal. With the parent ; fractal on the screen, redraw the image with imag(p3) set to ; 2400. A totally different image appears. ; ; I named today's image "Iterative Teardrops" because of the ; teardrop shape of the elements surrounding the central midget. ; These disconnected elements are typical of fractals whose ; formula contains negative powers of Z. The rating of 6 equals a ; little above normal on my rating scale -- about the mildest ; praise I could give to such a mundane image. ; ; The redeeming feature is the render time of 6 minutes, and the ; fact that the completed GIF image file may be downloaded from ; either of the following web addresses: ; ; ; ; ; ; The fractal weather Saturday here at Fractal Central was ; uneventful. The partly cloudy day with a temperature of 95F 35C ; and moderately high humidity was notable only because it ; continues the warmer and drier than normal pattern that has ; prevailed most all summer. Also it was the fourth day in a row ; on which the weather experts had predicted showers, and the ; fourth day in a row on which the predicted showers failed to ; arrive. Those experts are far better at explaining why ; something did not happen than forecasting what will happen. The ; fractal cats, who are unconcerned with weather experts, passed ; the day doing what cats do best -- lazing around the fractal ; grounds. ; ; As for me, it's Sunday morning, and if I really work hard, I ; might find a way to get through the day without working. And ; don't laugh. After all, working to avoid work is no more anti- ; productive than fighting for peace. Until next time, on the ; 20th, take care, and don't be too lazy. ; ; ; Jim Muth ; jamth@mindspring.com ; ; ; START PARAMETER FILE================================ IterativeTeardrops { ; time=0:06:12.45--SF5 on a P200 reset=2002 type=formula formulafile=allinone.frm formulaname=MandelbrotMix4 function=recip passes=1 center-mag=+3.31533979732890300/+3.380854530622418\ 00/2.718068e+010/1/17.4927412805414235/0.007870415\ 83158384211 params=1/-2/0.01/2/0/0 float=y maxiter=1000 inside=0 logmap=130 periodicity=10 colors=000GLKFNKNUTV`WbgZjnhtml90M_pwcipgbgkWZnPQe\ TNXXKOXHRbJTecVhLfkm_nNmqOctPzvQYqRQlSIgTBcUFdXJe_\ NfbRgeVhhTqpSYwRZwQOwbzocmidhcdcZe0TeUO_TPVTQPTRKT\ SFRTnGwjJtgMndPhaSbZVXWYRT`LQcGWaOa`WgZclYjghsbrwn\ auzLpjKmVJkFIi0Ig6RoBZvHmwMnwJcwHTwFIwD8wSCgfGTuJE\ tLFsMFsOGrPGrRHqSHqTH9WbDYeG_gJajMblPdnSfqVhsYiurk\ wzhtseiscZtf_pdbmbej`gg_jdYlaWoZVqWTtTRwQPwNOwKMwH\ KwEJwDIwCHwBGwAFw9Eu8Ds7Cp6Bm5Ak49h38e38cBDfVEkWCp\ XAuX9wO5pG2gK9lNGpQMtUTwXZw_ewbkwb_wbOwbCwb1wd2we3\ wf4wg5wh6wj6wk7wl8wm9wnAwoAwjRtegjaxadscfnehigjdil\ _knVmpQorLqtGsvBux6wz2wrDujOqbZnVijNsgQUwNWwKYwI_w\ FawDcvAet7gs5ir2kq0lp4fs7`uAVwDUwGVwJWwMXwPYwSZwU_\ wW`wZaw`bwbcwedwgewifwlgwnhwpiwsjwukwwlwymwvnwtowr\ pwpqsnrnlsiitdgu`evWcwRaxM_yIYzMWzQUzTSzXQz_OzcMzg\ LzjJznHzqFzuDzwBzw9zw8zwJzwUzwdzwozwnzwnzwnzwnzwnz\ wnzwnzwozwpzwpzspzopzkpzg } frm:MandelbrotMix4 {; 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, 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================================== ; ;
