Yes, I ; cheated. But look at yesterday's FOTD, and you will see why I ; cheated. The standard rendering of today's scene makes a really ; nothing image. I humbly admitted my guilt by naming the image ; "Fractal Cheating". ; ; I also cheated with the formula I used. To create yesterday's ; version of the scene, I used the MandelbrotMix3a formula and ; entered the critical -8.888 by hand. For today's version, I ; turned to the MandelbrotMix4 formula, which calculated and ; entered the initial value of Z automatically. The benefit is ; a great increase in speed, though with an image as fast as ; today's, the difference is not very large. ; ; Most of my fractals are calculated by iterating a simple ; function of a complex number, producing another complex number, ; until either the number exceeds some pre-defined bailout value, ; or the maxiter is reached. The pixel corresponding to the ; starting point is then colored based on the result of that ; calculation. The decomp feature turns on another coloring ; method, in which the points are colored according to which ; section of the complex plane the final value lies in. The ; decomp parameter determines how many sections the complex plane ; is divided into for this purpose. In today's image, the plane ; is divided into the maximum 256 sections. ; ; I would have rated today's image higher than a 5, but the ; coloring is less than satisfactory, and I just can't shake the ; feeling that it is not a real fractal. Apparently, just as man ; has philosophically done with the sensory-created mental image ; of a physical universe, I have arbitrarily created a reality. I ; have decided that that the 'outside=iter' method produces the ; 'real' fractal, and all other rendering methods are mere ; distortions of the one ultimate fractal reality. But at least, ; I am still aware that I myself have created and decided what is ; fractal reality. ; ; The rating of 5 equals an overall value of 281 when the 1-3/4 ; minute render time is considered. The time required to download ; the image from: ; ; ; ; is roughly the same. ; ; A warm sunny Sunday here at Fractal Central gave the dynamic duo ; ample time under the holly trees. When evening came, they were ; totally exhausted from doing nothing, and came inside for their ; evening meal without hesitation. In the late evening, a severe ; thunder-storm arose, which brought down a large limb from one of ; the fractal trees. But, other than the need to eventually ; remove the fallen limb, no harm was done, as it fell in the ; alley beside F.C. This morning is cloudy, chilly and damp, with ; occasional rain. What will the cats do to adapt? ; ; The most immediate task for me is to put the work that is now in ; front of me behind me. Then it's on to the fractals, and maybe ; that tree limb. Until next time, take care, and a fractal a day ; may keep the doctor away, but five hundred a day will bring the ; doctor running. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE================================ Fractal_Cheating { ; time=0:01:46.83--SF5 on a P200 reset=2003 type=formula formulafile=allinone.frm formulaname=MandelbrotMix4 function=ident passes=1 center-mag=-22.97767772633961000/+0.06349061612053\ 014/3.426261e+008/1/-152.5/0.000251818031069418746 params=1/2/0.075/3/0/0 float=y maxiter=300 inside=0 logmap=34 decomp=256 periodicity=10 colors=000cmzzzVzzWzzWzyWzxXzwXzvXzuXztWysWxsVwrVv\ qVuqUtpUspUroTqnTpnTomSnmSmlSlkRkkRjjQijQhiQghPfhP\ egPdgOdfOceObeNbdNadNacM`bM`bL_aL_aLZ`KZ_KY_KYZJXZ\ JWYIWXGVXFVWEUVCUVCTUCTUBSTDSSDRSERRFQRGPQHPPIOPJO\ OKNOLNNMMMNMMOLLPLLPKKPKJPJJPIIPIIPHHPHGPGGPGFPFFP\ FEPEDPEDPDCPDCPCDPCEPCEPCFPCGPCGPCHPCIPCIPCJPBJPBK\ PBLPBLPBMPBNPBNNBOLBPJBPHAQFAQDARCASCASCATCAUEAUEA\ VEAWF9WF9XF9XF9YG9YG9ZG9ZG9_H9_H9`H8_G9aH9`H9aHAaH\ AaHAbHAbHBcHBcHBcHCdHCdICdICeIDeIDfIDfIDfIEgIEgIEg\ IFhIFhIFiJFiJGiJGjJGjJGjJHkJHkJHlJIlJIlJImKImKJnKJ\ nKJnKKoKKoKKoKKpKLpKLqKLqKLqLMrLMrLMrLNsLNsLNtLNtL\ OtLOuLOuLNvMOuLOtLOsLPsLPrLPqLPpLQpLQoLQnLRmLRmLRl\ LRkLSkLSjLSiLThLThLTgLTfLUeLUeLUdLVcLVcLVbLVaLW`LW\ `LW_LXZLXYLXYLXXLYWLYWLYVKZUKZTKZTKZSK_RK_QK_QK`PK\ `OK`NK`NKaMKaLKaLKbKKbJKbIKbIKcHKcGKcFKdFKdEKdDKdD\ KeCKeBKeAKfAKf9Kf8Kf7Kg7K } frm:MandelbrotMix4 {; 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, 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================================== ; ;
