This option draws concentric circles around the ; minibrots of all orders. When the centers of the circles are ; cut off, it is unlikely that minibrots will be found in the ; area. ; ; When I tried the 'fmod' option on today's scene, I saw almost at ; once that the circles are cut-off, which means there are no ; hidden minibrots. But I was surprised by the pattern created by ; the cut-off circles themselves, and refined it into the FOTD for ; April 29. ; ; The image uses only the final 1/3 or so of the color palette, ; which makes it basically a monochrome image. I tried several ; full color palettes, but none turned out as well as the silvery- ; blue one I used in the image. ; ; At this point I must humbly apologize for the spiral aspect of ; the image. I sometimes put down fractals with spirals, because ; we see so many of them, but this does not imply that I consider ; all fractal spirals fit to be cast aside. The spiral tendencies ; of today's image are what raised it to a rating of a 7. ; ; The name "That Old Black Magic" expresses my fascination at the ; way numbers can create entire infinite worlds, perhaps our own ; universe as well. ; ; The calculation time is a measly 33 seconds. The minor inconven- ; ience of running the parameter file may be avoided by viewing ; the finished image at: ; ; ; ; and in high-definition at: ; ; ; ; The original FOTD web site is located at: ; ; ; ; Heavy rain returned to Fractal Central Wednesday night, but the ; newly installed sump pump did its job, and the fractal basement ; suffered nothing more spectacular than a couple puddles. It's ; not ideal, but on a flood plain in a month of record rainfall, ; it's much better than manning and womaning the bailing buckets ; in the middle of the night. ; ; The rain moved out by daybreak Thursday, leading to a pleasant ; day, with partly cloudy skies and a temperature of 79F 26C. The ; fractal cats spent the day sleeping, which is what all cats do ; best. The next FOTD is due to be posted in 24 hours. Until ; then, take care, and don't warn others that they must do some- ; thing about 'man-made' climate change, aka global warming, until ; you are ready to park your own car for good. ; ; ; Jim Muth ; jamth@mindspring.com ; ; ; START PARAMETER FILE======================================= ThatOldBlackMagic { ; time=0:00:33.29-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=MandAutoCritInZ function=recip center-mag=0.0378359/-2.24077/30/1/90/0 params=11/-1.1/1.1/-11/0/0/0/0 float=y maxiter=1500 proximity=1.12 outside=fmod periodicity=6 colors=000OczQbzSazU`zW_zX_zZZz`YzbXzdWzfVzgVzXboM\ jaBrN0z91y81y81y81x81x81x71w72w72w72v72v62v62u62u6\ 2u62qB2mF2iJ2eO2aS2YW3XZ3W`4Vb4Ud5Tg5Si6Rk6Qm6Pp7O\ r7Nt8Mv8Ly9Kz9Jz9IzLipKipKhpJhpJhpIhpIhpHhpHgpGgpG\ gpFgpFgpEgpEfpDfpDfpCfpCfpBepBepAepAep9ep9ep8dp8dp\ 7dp7dp6dp6dp5cp5cp4cp4cp3cp3cp5bo6bo7bn8bn9bmAamBa\ lCalDalEakF`kG`jH`jI`iJ`iL_iM_hN_hO_gP_gQZfRZfSZfT\ ZeUZeVYdWYdXYcYYcZYcYXbXWaWW`WV`VV_UUZTUZTTYSSXRSX\ QRWQRVPQVOQUNPTNPTMOSLNRKNQCHIKMQJMPILOzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzyzzxzzwyzvxz\ uwztvysuxrtwqsvpruoqtnpsnpsmorlnqlnqkmpjmpjloiknhk\ nhjmgjlfilfhkehkdgjdgicfibehbegadg`cf`cf_beZbdZadY\ `cX`bX_bW_aWZaVY`UY_UX_TXZSWYSVYRVXQUXQUWPTVOSVOSU\ NRTMQTMQSLPSKPRKOQJNQINPIMOHMOGLNFKMEJLDIKCHJBGIAF\ H9EG8DF7CE6BD5AC49B38A279 } 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========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
