Today's shows an interesting Seahorse-Valley type Julia ; set. The parent fractal came about when I divided Z^2 by ; (Z^(10)+2.5) before adding C. This parent fractal only vaguely ; resembles the familiar Mandelbrot set. It has a Seahorse Valley ; that is almost impossible to find, but I must have come pretty ; close, because today's image certainly has Seahorse-Valley Julia ; characteristics. ; ; It also has lots of Z^12 characteristics, which are visible all ; through the image as a series of circular features with 12 ; sections each. Unfortunately, with its rating of 7.5, today's ; image falls short of yesterday's. But it is still worth a look, ; especially with a calculation time of only 29 seconds. ; ; The name "A Strange Seahorse" pretty well describes the image. ; ; As always, the already-calculated GIF image is or soon will be ; posted on the FOTD web site at: ; ; ; ; for instant, fully hedonistic ecstasy. ; ; The weather continued absolutely perfect here at Fractal Central ; on Monday. With the work light, FL and I took a couple hours ; off in the afternoon for a 3-mile walk along a nearby hillside ; trail. The temperature of 82F 28C made walking as enjoyable as ; it gets. When we returned, the fractal cats scolded us for the ; unaccustomed absence. The next FOTD will be posted in 24 hours. ; Until then, take care, and change the change that never changes. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= A_Strange_Seahorse { ; time=0:00:29.25-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=DivideJulibrot center-mag=0/0/0.4014516/1/-30/0 periodicity=10 params=90/90/90/90/-1.98955/0.67403096/0/0/12/2.5 float=y maxiter=600 inside=0 logmap=3 colors=000ZZccchhhmmmrrrwvvzxyzwwzwtvwqrwomwnhwmfw\ mdwlbwk`wjZwjYrfVmbSi_QdWN`SKWPISLFNIDJEAEA7A75532\ 100LtheM3hL4kL4mK5pK5sJ6uJ6xI7zI7xNCwSHvWMt`RseWri\ `icb`ZddWagU_kSYnPWrNUuLSxJQvIWtIasIggFeXCdM9cOBXQ\ DQSFJTGDVIBWK9XM8YN6ZP4_R3`T1aU0`wGPqQEl_3giA_aHSV\ OLOVDH`6AWB8SG7OL6KP5GU4CZ38b26_94XG2VN6ZL9aJCeIFh\ GIkFMiYQrzSkmSdcS_WSTSSNBSJ6SF2JO8BXD6XqB`rFcsKftO\ juTmvXpvXouWntWmsVlrUkqUjpTioThnSgmRflRekQdjQdiPch\ ObgOaf101N`eN_cMZbLYaLX`KW_KVZJUYITXISWHRVHRUGQTGP\ SFORGF_HGZHIYIKXIMWJOVJQUKSTKTTMYUObVPfWRkXSoYTkVT\ hTUeRUbPV_NVXLWUJWRHWNFXKDXHBYE9YB7Z85Z53Z21T42O53\ I63D74884AC7CF9EJCFMEJNIMNLPNPSNSVNVYNZ`NacNefNhiN\ klNooNrrNunTpjZlfdgcjchWhmHmz2r`ClLMfmWKDeJbk1W_Dg\ KPr5`s4Xt4Tu3Pv3Lw2Hx2Dy19y15M0YO4_P7aQAbSEdTHeUKg\ VNhXRjYUkZXm__nacpbfqcisdltaiqZgnWelTciRagO_dLYbIW\ _FUXDSVAQS7OQ4MN2KLBQRJVW } 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
