And in honor of ; the occasion, as if it needed honoring, we have a fractal. ; ; Today's fractal combines elements of Z^2+C and Z^2.5+C, and ends ; up looking quite like an oversized version of a Julia set of the ; Z^2.003 Mandeloid. In fact, today's scene is a Julia set of the ; East Valley of the large minibrot on the main spike of its corr- ; esponding Mandeloid. It closely resembles one of the Julia sets ; of the same area of the Z^2.003 Mandeloid, the Julia set that ; holds the curious rectangle where I occasionally return in ; search of a FOTD. I have not yet found any rectangles in ; today's Julia set however, but then I have hardly started to ; search. ; ; I named today's image "Railyard Symphony" because the tangle of ; filaments reminds me of the well-known (at least to rail buffs) ; Enola Railyards, about 65 miles down the river from F.C. ; ; I rated the image at an 8, leaving it to the individual ; fractalist to decide whether it's worth this rating. ; ; One thing that can not be exceeded is the brevity of the calcu- ; lation time, which at a faster-than-light 19 seconds, actually ; threatens to go backward in time. Those who would rather avoid ; the risk of becoming a child again, may find the image, already ; calculated, on the FOTD web site at: ; ; ; ; A near perfect day here at Fractal Central was compromised by a ; brief but heavy thunder-shower in the afternoon, which dropped ; the temperature from an already pleasant 81F 27C to an almost ; chilly 68F 20C. The fractal cats ignored the weather and spent ; most of the day playing hide-and-seek in the nooks and crannies ; of the bookshelves in the long hallway of FC. ; ; My day was pleasant enough, and with any luck at all, tomorrow ; will be the same. The next FOTD is due to be posted in 24 ; hours. Condidering the regularity of the FOTD postings, I feel ; it will appear on schedule. Until then, take care, walk lightly ; and carry a big fractal. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Railyard_Symphony { ; time=0:00:19.01-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=DivideJulibrot center-mag=0/0/0.3133196/1/-90/ params=90/0/90/0/-43.762/0/0/0/2.5/25 float=y maxiter=1500 inside=0 periodicity=10 colors=000U71U81U94UA7UBAVCDWDHXEKYFNUGQWHTYIX_J_a\ KbbLecMhcMkeNifNhhOgiOfjPelPcmQbnQapR`qR_sSYtSXuTW\ wTVxUUyUTuTPqTMnTIjTFgTBcT8`T5aV4bX4bZ4c`3cb3dd3df\ 3eh2ej2gm2kp2ps1vv1zy1vv1pp2ej2Xc2OY3JT3EP39M3BK8D\ SDFWIHfNIjRJiPJbOJ`NKZLKXKKVJLTHLRGLOFMNDMMCMLBNK9\ NJ8NI7NH6QFASEDzDHzCKzBNzARz9Uz8Yv7`r6cm5gm4jz3nz2\ qz1tz5so8skBshEsdIs`LsYOsURrQUrMYrJ`rFcrBfr8ir9fsA\ dtBauC_uDXuEVuFSuGQuHNuILuJIuKGuLDuMBuN8uN6uNBuNGu\ NLuNQuNVuN_uNcuLauK_uIYuHWuGUuESuDQuCPuJNuPLuVKu`I\ ufGulFufEu`EuWDuQDuKCuFCu9Bu4Bu5Au5Au69u69u78u78u7\ 7u87u86u96u95u95uA7uB8uB9uCAuDBuDCuEDuFEuFFuGGuHHu\ HIuKTuMcuPnuRxuNouJfuFZuBQu8IuE9uJ1uQ8uXFubMuiTuoZ\ umWukTuiRugOueLucJuaGu_DuYBuW8uU5uT3u2iuRuuPpuNluM\ huKduJ_uHWuGSuEOuDJuBFuABu87u73u7Xu7zuIouTeucVunLu\ gJu`HuWmuVmuOhuHduA`u4Xu5Yu6Yu7Yu8Zu9ZuAZuAZuDXuFW\ uHUuJTuLSuSUuYWucXuiZu_7u } frm:DivideJulibrot {; draws 4-D slices of DivideBrot Julibrots pix=pixel, u=real(pix), v=imag(pix), a=pi*real(p1*0.0055555555555556), b=pi*imag(p1*0.0055555555555556), g=pi*real(p2*0.0055555555555556), d=pi*imag(p2*0.0055555555555556), ca=cos(a), cb=cos(b), sb=sin(b), cg=cos(g), sg=sin(g), cd=cos(d), sd=sin(d), aa=real(p5)-2, bb=imag(p5)+0.00000000000000000001, p=u*cg*cd-v*(ca*sb*sg*cd+ca*cb*sd), q=u*cg*sd+v*(ca*cb*cd-ca*sb*sg*sd), r=u*sg+v*ca*sb*cg, s=v*sin(a), c=p+flip(q)+p3, z=r+flip(s)+p4: z=sqr(z)/(z^(-aa)+bb)+c |z|< 1000000 } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
