The greatest ; surprise is the empty triangle that appears where East Valley ; would normally be found. Today's image is located on the ; outside the of southern shore line of this triangle. ; ; I rated the image at a 7 rather reluctantly. The colors are a ; bit too busy for maximum effect. The name "Mainstream Fractal" ; has ho connection at all to the image. It's simply the first ; thing I could think of. ; ; The image is a rather slow one, with a calculation time of over ; 18 minutes on the fireball P4-2000, and well over one hour on ; the old P200 machine. But calculation will be no issue for ; those who view the finished image on the FOTD web site at: ; ; ; ; Sunday was spoiled here at Fractal Central when the temperature ; reached a high of 90F 32C. But if the humidity had been higher, ; it would have been worse. The fractal cats must have agreed, ; for they seemed totally satisfied with their life of perpetual ; indoor confinement. ; ; My day was spent recovering from Saturday's outing. The next in ; the near endless series of FOTD fractal images will appear in 24 ; hours. Until then, take care, and step lightly. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Mainstream_Fractal { ; time=0:18:18.07-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=MandAutoCritInZ function=ident passes=1 center-mag=+21.44692078468248/-0.000630261989078/\ 1.042898e+009/1/-80/0.0150935738509659703 params=250/-1.1/-250/-0.9/0/0/0/0 float=y maxiter=12000 inside=bof61 outside=real logmap=1274 periodicity=10 mathtolerance=0.05/1 colors=000000WALW9LV8LV7Ld_mcZmaYm`Ym_XmYWmXVmWUmU\ TmTSmSRmQQmPPmOOmMNmLMmKLmJLmXebK1gI2hH2hG2hE2hD2h\ C2hB2h93h83h73h53h43h33h23h65gA7fE9fIBeMDePFdTHcXJ\ c`LbdNbhPakQahUceXdc`e`cfZfgWjhTmiRqjOtkMwlQvkTukW\ tkZskarkdqkgpjjojmnjpmjsljvkjykjxlhxlfxmexmcxnbxn`\ wo_woYwpXwpVwpTwqSwqQvrPvrNvsMvsKvtJvtHvtGusFtrEsq\ EzjzroDqnCpmBomBolAnkAmj9li8kh8kg7jg7if6he5hd5gc4f\ b4ea3ea3b_4_Y5XW6UU7RS8OQ9LOAIMBFKCCID9GE6EF3CG0BH\ 1EK2HM2KP3MR3PT4SW5UY5X`6_b6ad7`c7_c7_c7Zc7hc7tc7S\ c7Cc8Wc8Wc8Vc8Uc8Ub8Tb8Tb8Sb9Rb9Rb9Qb9Qb9Pb9Ob9Ob9\ Nb9NbFK`LIZQGXWDV`BTf9Rk7PjCLjGIiKEiPBhT7hX4h`1iZ3\ zm5jX6jW8kV9z`BlTCzSEzRFzQHzPInOKoNLoMNpLOpKQqJRqI\ TrHUrG0sFXsEAtD_tCKuBbuAUv9ev8cv7hu8mt9ftAusAdrBzr\ CbqDzqDapEzoF_oFznGYmHvmIWlIrlJVkKmjLTjLhiMRhNchNQ\ gOZgPOfQUeQMeRPdSKdSKcRLcQLbPLbOLaNLaMLaLL`KL`JL_J\ L_IL_HLZGLZFLYELYDLXCLXBL } 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
