It is of ; order 1.5 and lies in a parent fractal that resulted when I ; iterated the expression Z^(1.5)+C at a level 33 levels up the ; hyperladder with no function applied. The name "It's Not ; Quadratic" confirms the apparent discrepancy. ; ; This parent is shaped quite like the minibrot in the image, and ; is oriented so that the large period-2 bud points out to the ; south. Today's scene is located in a sprawling chaotic spiral ; just inland from the southeast shore line of the parent's main ; bay. ; ; I intentionally set the logmap about 25 levels too high. Doing ; this created a flat background that could be given any color I ; wished. For various reasons I chose solid black. ; ; The art rates a 7, mostly because of the flat black background. ; The math rates a 6, since the math trick is so old that it is ; hardly a trick any longer. ; ; The calculation time of 1-1/2 minutes is fast enough. But visit ; the web sites for an even faster way to view the image. ; ; The web sites are online at: ; ; ; ; ; ; ; ; ; ; Lots of clouds with only a few breaks of sun spoiled the day ; here at Fractal Central. The brisk north wind and temperature ; of only 54F 12C made things even worse. The fractal cats ; endured the discomfort with only minor complaints. The humans ; had no complaints at all -- we were too busy. ; ; The next FOTD will be posted in about 24 hours. Until then, ; take care, and let's avoid discussing religion, politics or ; philosophy for a few days. ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= It's_Not_Quadratic { ; time=0:01:30.00 SF5 at 2000MHZ reset=2004 type=formula formulafile=basicer.frm formulaname=MandelbrotBC3 function=ident passes=1 center-mag=+0.7796928496537461/-0.5595061592029913\ /3.314487e+008/1/112.5/0 params=1.5/0/33/0 float=y maxiter=2400 inside=0 logmap=162 periodicity=6 colors=000000SafRWfPQfOKgMEgLGgKKgPPpUUxWZvXcuYhtZ\ ms_or`qqctphwpmznrzjjzgdoddgadeZdUmdUmdUmdKmdKmdKm\ dKmdKzdKzdKzdKzZKzUKzPCzQKzRKzUKzWKzZKz`KzcQzePzfQ\ zgRzgRzhSzhSmzcmzcmzcmzcmzcmzcmzcmzcmzcmzcmzcmzcmz\ cmzcmmcmccmUcmKcmIcmLcjOcgRccTc_WcXZcTacPdcMfcIidE\ leBof7qg4kf8eeB_dEVdHTaKR_NPYPOWSMUUKRXIPZHNaFLdDJ\ fBGiAEk8Cn6Ap48s36u5At6Dt7Ht9KsAOsBRsDVsEYrFarHdrI\ hrJkqLoqMrqNuqe_ZwEHpHOiJUbL_WNeQPkTSjWVjYYi`_icbi\ eehhghkjhmmgppgsrguufxxfzzfzzazzWzzR4mMFmPQmS`mVjm\ YlmVnmTocQqcOscMtcJvcHwcFvcGucHtcHscIreJrkJllGflE`\ lCWlAZfC``EccGecIhcKjcMlcN8hxHhyKhhPcbUcXXcVZcTacR\ cePehNhjLjmJloHhoFdoE`oDYoC_nBanBczAezAizAjz9kz9lz\ 8mz8nz8oz7pz7qz7rz6sz6tz5uzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzz } frm:MandelbrotBC3 { ; by several Fractint users e=p1, a=imag(p2)+100 p=real(p2)+PI q=2*PI*fn1(p/(2*PI)) r=real(p2)+PI-q Z=C=Pixel: Z=log(Z) IF(imag(Z)>r) Z=Z+flip(2*PI) ENDIF Z=exp(e*(Z+flip(q)))+C |Z|
