This is because the ; image was generated by the expression Z^(sqrt(2))+C calculated ; 14 turns up the complex logarithmic hyperspiral with the 'recip' ; function applied. ; ; The parent fractal is a Mandeloid with a teardrop-shaped main ; bay, rotated so that its main bud faces southeast. It has only ; one period-3 bud, but the usual higher order buds. The scene of ; today's image is in a field of debris located where the second ; period-3 bud might normally be expected to lie. ; ; The rating of a 7-1/2 includes the standard 1/2-point bonus for ; my color work. The image itself is merely average. To achieve ; the flat-background effect, I rendered the scene with the logmap ; set to an artificially high 67. ; ; The shape of the minibrot at the center mirrors the shape of its ; parent, which is a quite common thing in fractals with exponents ; of Z between 1 and 2, where the parent fractals can assume most ; any shape they wish, especially when calculated with alternate ; values of the logarithm. ; ; The calculation time of 32 seconds is blessedly brief, so why ; not run the included parameter file and see what you might have ; missed. ; ; The finished image is posted at: ; ; ; ; for effortless viewing. ; ; It is posted in high definition at: ; ; ; ; The original FOTD web site may be accessed at: ; ; ; ; The partly cloudy skies were fair enough, and the temperature of ; 70F 21C was agreeable enough here at Fractal Central today. But ; the frequent showers made it a day to be forgotten. The fractal ; cats, ever forgetful, had already forgotten the day when it ; began. ; ; After almost 3 inches, 7cm, of rain overnight, the humans were ; glad they had installed the sump pump. A floor with a few ; puddles is far better than a basement filled with 100cm of ; water. The next FOTD will be posted in 24 hours. Until then, ; take care, and if you would like to become wealthy in this sour ; economy, open a shoe store for bigfooted sasquatches. It must ; be quite uncomfortable for them, stomping around in the cold mud ; in their bare feet. ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= Squarely_Rooted { ; time=0:00:25.01-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=MandelbrotBC3 function=recip passes=1 center-mag=-1.4597524206/-0.4141910317/25206/1/85/0 params=1.414213562/0/14/0 float=y maxiter=2000 inside=0 logmap=67 periodicity=6 colors=00000KxZJzwCzzzFmC9qz9gz9Yz9Pz9Fm96g8D`7JV6\ PP5WJ4aD3g72m16cBAVKEMUIDbM4kZIWkVHwg2ubCtYMrTWqOe\ mW_tlXslXslXslXsmXsmXsmXrmXrmXrmWrmWrmWrmWrmWqmWqm\ WznWznWznVznVznVznVznVznVzmVznVzoVzoUznVzmWzlXzkXp\ kYpjZpi_ph_ph`pgapfapebpecpddpcdpbepafpafp`gp_hpZi\ pZipYjpXkpWlpWlpVmpUnpTnpSopSppRqpQqpPrpPspOspNtpM\ upMvpLvpKwpJxpJxoLwnMvmNulOtkPsjQriRqhSpgTofUneVmd\ WlcXkbYjaZi`_h_`gZafYbeXcdWddVecUfbTgaSh`Ri_QjZPkY\ OlXNmWMnVLoUKpTJqSIrRHsQGtPFuOEvNDwMCxLCzLDzKEzKFz\ JGzJHzJIzIJzIKzHLzHMzHNzGOzGPzFQzFRzFSzEfzzfzzfzzf\ zzfzzfzzbzzZzzWzzSzzPzzNzzMzzLzzJzzIzzHzzFzzDzzBzz\ Azz8zz6zz5zzCzzIzzOzzUzzSzzRzzQzzPzxXzjczXkzJrz5qz\ 8pzAozCnzEnzGrzkNzXLz_KzaJzcHzfGzhFzjEzlLzhSzeZzae\ zZlzVszSgzNWzIKzD8z9PzDdzGtzJtzKtzLtzMtzMtzNtzOtzP\ tzPmzSfzV_zYUz`NzcGzfAzhEzfIzdLzbPzeTzgXzj_zlczogz\ qkztnzvizWdz6YzHSzSLzaFzl } 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|
