In that image it is apparent that another ; fractal lies buried beneath the surface fractal, but because the ; surface fractal is critical, that hidden fractal must be forever ; obscured. But things are not nearly as bad as they first ; appear, for in today's image I take away the surface stuff and ; reveal that phantom fractal in its full glory, which explains ; the name "The Phantom Revealed". ; ; The trick lies in choosing the alternate critical value of ; initial Z. The generating expression actually has two critical ; values. In the previous image, the initial value of Z was ; automatically set to zero, one of the critical values. In ; today's image, I have reset the value of initial Z to -1, the ; second critical value. The result of this change is to move the ; previously buried fractal to the surface, and bury the fractal ; that was previously on the surface. Fragments of the previous ; surface image now appear as the bits of orangish stuff scattered ; about today's scene. ; ; Calculating complex critical values is not much fun. One of ; these days I might find a formula that can switch the critical ; values of initial Z automatically, but that day is not in the ; foreseeable future. Until then, I will continue to find the ; alternate critical values with the graphic method. ; ; The rating of a 7 totally reflects the mathematical value of the ; image. The artistic value hardly exists. But I will dive into ; today's image and post what I find there as tomorrow's FOTD. ; Who knows, I might find something worth a higher rating. ; ; Check the fractal phantom at: ; ; ; ; With a deeper analysis at: ; ; ; ; And the spooks from the past at: ; ; ; ; Typical midwinter weather prevailed at Fractal Central today, ; with a temperature of 28F -2C and frequent but light flurries of ; snow. The fractal cat made a break-out but got caught before he ; got into trouble, and was soundly scolded for his efforts. The ; humans made it through the day with only one spat, which was due ; to FL's testiness. My patience, approaching that of Job, kept ; things under control however. The next FOTD will be posted in ; 24 hours. Until then, take care, and when will the over-zealous ; technophiles realize that technology cannot solve all of man's ; problems because it has created many of them itself? ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= ThePhantomRevealed { ; time=0:00:10.00 SF5 at 2000MHZ reset=2004 type=formula formulafile=basicer.frm formulaname=MandAutoCritInZ function=cosxx float=y center-mag=0/0/0.69 params=-2/2.3/1/4.6/-0.02/0/-1/0 maxiter=750 inside=0 symmetry=xyaxis periodicity=6 colors=000GSNTT_RVaQXbOZdNaeLdfKhhIliHpkFplEomCnoB\ mpAmq9mn8mk8kh7if7gc6f`6eZ5dW4cT4bQ3aO3`L2_I2ZG3YK\ 4XO4WR5VV5UYzmazmdzmezmfzmfzmgzmgzmbzmZzmVzmQzmMzm\ IzmIzmIzmIzmJzcJzcJzcJzcJzcJzcJzcJzcJzcJzcJzcKzcKz\ XKzXKzXKzTOzXKzWKzWKzWKzWKzWLzWLzWLzWLzWLzVLzVLzVL\ zVLzVLzVLzVMzVMzVMzUMzUMzUMzUMzUMzUMzUMzUNzUNzTNzT\ NzTNzTNzTNzTNzTNzTNzJOzLNzNNzPNzRNzLMzMNzMNzNNzNNz\ NNzONzONzPNzPNzPNzQNzQNzRNzRNzRNzSNzSNzTNzTNzgQyfP\ xfPwePwePvePudPudPtcPscPrcPrbPqbPpaOpaOoaOn`Om`Om_\ Ol_Ok_OkZOjZOiYOhYOhYOgXNfXNfWNeWNdWNzVNzVNzUNzUNz\ UNzTNzTNzBYzCXzDXzDWzEWzFWzFVzGVzHUzHUzIUzJTzJTzKS\ zKSzLSzMRzMRzNQzOQzOQzPPzQPzQOzROzSOzSNzTNzdWzaTzZ\ RzWPqqJppKooKonKnnKnmKmlKmlKlkKzjLziLziLzhLzgLzgLz\ fLzeLzdLzdMzcMzbMzbMzaMz`Mz_Mz_MzZMzYNzYNzXNzWNzVN\ zVNzUNzTNzx`zw_zv_zu_zuZztZzsZzrYzrYzqYzpXroXzoXzn\ WzmWzlWzlVzkVzjVziUziUzhU } 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 ;
