I named it "Where ; Trees Come From" because with only a slight change of ; parameters, I could turn the Julia image into one of those ; fractal trees. ; ; But today we have no trees. We have a surreal something, ; vaguely resembling a slavic helmet, better seen than described. ; There is no way I could honestly rate such a quickie image, so ; I let it go unrated. ; ; The calculation time of just under 9 minutes is longer than I ; would have preferred. But give Paul a chance to calculate and ; post the image, then rush to the FOTD web site to enjoy it. The ; web site may be accessed at: ; ; ; ; With full sun and a temperature of 79F 26C, Saturday was the ; picture of perfection here in the Fractal Central area. The ; fractal cats must have agreed, for in the late evening when we ; returned from the day out, we found three waste baskets over- ; turned and the contents scattered -- a sure sign of bored and ; discontented cats. ; ; With little harm done, I managed a FOTD, though a bit too late ; to post on time. However, the next FOTD will be posted on time ; in 6 hours or so. Until then, take care, and fractals are the ; spirits of numbers, or are numbers the spirits of fractals? ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= WhereTreesComeFrom { ; time=0:08:53.54-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=dividejulibrot passes=1 center-mag=45.1158/0/0.1140451/1/90/0 params=90/0/90/0/-105.58135/0/0/0/1.5/100 float=y maxiter=3000 inside=bof61 periodicity=10 colors=000JYCIVCHTBGQAGO9FL9EI8DG7CD6B74CB6DF8EJAE\ MCFQEGUFHYHH`JIdLJhNJkOKmQKnSLpULqXMsZMt`NvbNwdMtg\ LqjKnlJloIirHftGcwGayFbwFbvEcuEcsDdrDdqDdoCenCemBf\ kBfjAgiAggAgf9he9hc8ib8ia8i`PU_eF_u0_t2`s4ar6bq7cq\ 9dpBeoCfnEgnGhmHilJjkLkkMklQmlUnlYolapmermismmtmpu\ korjnphmmglkfkhdjfcicbha`ib_icZidYjeXjeVjfUkgTkhSk\ hRkiQljOlkNlkMmlLmmKmnJmnIkkIjiHigHheHgbGf`GeZGdXF\ cUFbS8nsAmtBmtCmtDltEltGltHktIktJktKktMjtNjtOjtPit\ QitSitThtUhtVhtWht_arbWqeQjgLdjGYlASo5Lq0Fp2Hp4Io6\ Jo8KnALnCMmEOmGPmIQlKRlMSkOTkQUjSWjUXiWYiYZi__ha`h\ cagecggdfiefkfemgeohftjeqidnhckgcigbfface``e`Zd_Wc\ ZTcYQbYOaXLaWI`VF_VD_UAZT7YT5YU6XV6XV6XW6XW6XX6XY6\ XY6WZ6WZ6W_6W`7W`7Wa7Wa7Vb7Vc7Vc7Vd7Vd7Ve7Ve7VWmXV\ kYUiZUhZTf_Se_Sc`Rb`Q`aQ_aPYbOWcOXcNTdMSdMQeLUeKNf\ JVzKMfLZdLSbMzzMY_NdjNcWzzzPiSPoRQoPzzNRuLSvLRwKfz\ JPrIOoIOmHNsGMgFLeFKbEK`D } 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
