The obvious reason ; is that it reminds me of butterfly cookies. In fact, it reminds ; me so much of the cookies that, when I saw the image, I ran to ; the local store to pick up a box. ; ; The recipe behind the cookies combines a measly 0.1 part of Z^2 ; with a full part of Z^(-3) then adds C on each iteration. The ; resulting parent fractal is an oversized thing closely resem- ; bling some of those created by the parallel-resistance formula ; posted on the list a week or so ago. Its Mandelbrot shape is ; apparent, but the normally empty inside parts are filled with ; all kinds of superfluous decorations. Today's scene lies on the ; X-axis just beyond a large minibrot on the skeletal negative ; spike. ; ; The rating of a 7 is an improvement over yesterday's, but still ; leaves lots of room for improvement. Hopefully, tomorrow's ; image will rate an 8, but there is no guarantee that it will not ; check in at a rating of an embarrassing 6. ; ; One thing not in dispute is the speed of today's image. On my ; far from SOTA machine it finishes in 20 seconds. Some of the ; current units will finish it in far less time, that is if they ; can run the old Fractint DOS program at all. Regardless, the ; image is available on the FOTD web sites. ; ; The official FOTD web site with the finished image may be found ; at: ; ; ; ; Augmented variations of the image are online at: ; ; ; ; and the FOTD back images are at: ; ; ; ; The weather was near perfect here at Fractal Central today, with ; photoshop (old-kodachrome) blue skies and white cotton-puff cumu- ; lus clouds. The only thing not perfect was the temperature, ; which at a high of 57F 14C was notably chilly for late April. ; The fractal cat would have preferred more sun on his shelf. But ; now that the sun is at a much higher angle it strikes only the ; edge of the shelf closest to the window. The humans, not very ; concerned with sun angles, had an average day. ; ; The next FOTD will be posted in a number of hours. Until that ; mysterious number of hours passes, take care, and thanks to ; science we have life better today than at any time in the past. ; Why then are so many people dis-satisfied with their lives? ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= Butterfly_Cookies { ; time=0:00:20.00 SF5 at 2000MHZ reset=2004 type=formula formulafile=basicer.frm formulaname=MandAutoCritInZ function=ident center-mag=-14.05247665674564/0/1.18392e+009 params=0.1/2/1/-3/0/800/0/0 float=y maxiter=750 inside=0 logmap=88 symmetry=xaxis periodicity=6 colors=000000012034556A78FAAKDCPGEUJGZMIcRKhXNmcPr\ jRe_WSQ`EGe06i9KjIXkRikLmrPpzUtzZwzczzhzzmzzrzzzzz\ K6KHAUEEcBIoHNiNRcTVYZZS_bO_eL_iH`lE`pAcs7ms7ms7ms\ 7zs7zszzszzozflLfiSffZfcef`khcSie9iaIjYQjUZkQgkMom\ YinhcosZgta`udUugOdiQfjThkVjlgqTsx9nlFjaKfQQbFV_JW\ XNXURXRVYOZZMaZL`zL_zLZzLZzPbzTfzXjz`nhdrphuxevobw\ g_x_XySVzKchclRwpIjs9Zv1No5Oi8PcBQYERRHSLKTFNU9QU9\ Ob9MkmKsmA1mD8mFEzILzKRzNYzPcQghjylountqoympunmrok\ npikqfgrddsbas`YwWKri6nv5mn4mf3m_2mS1mL0mD0m61iC2f\ I2bO3_U4W_4Te8W_BYVF_QIaLLdFPfASh5Vj0Si8QhFOgMMfTN\ bROZQPWPZXGbWEfWCiWAmW8qW6tW4pY8m_CiaGfcKbeO_gSWiW\ TjZWkYZkXakXdlWglVilVzdTzXRzPQzHOz9NzOdzauzZozXjgV\ ddT_aZ`ZcaWhbTmcQrdUs_XsV`tRctMgtHjuDnu8qu4rrCspJt\ zQqzPnzOkzNizMdzR_zWVz`QzdLziGznBzs7zwDzmJzdPzWVzM\ `zDfz4ez9dzDczIbzMazRazV`zX_zZZz`YzbXzdMzfBzh1ziBz\ ZKzOTzDWzHZzKazOdzRgzU`zT } frm:MandAutoCritInZ {; Jim Muth a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=1/f, h=1/d, j=1/(f-b), z=(((-a*b*g*h)^j)+(p4)), k=real(p3)+1, l=imag(p3)+100, c=fn1(pixel): z=k*((a*(z^b))+(d*(z^f)))+c, |z| < l } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
