This mixture produces a Mandelbrot-like figure ; rotated 180 degrees with two sizable extra bays sprouting like ; butterfly wings from its butt end. Today's scene is located on ; the south shore of the new valley separating these two extra ; bays. ; ; Most of the interest was achieved by rendering the image with ; the outside set to 'tdis' and the inside set to'fmod' with the ; default proximity factor of 0.01 in effect. The mathtolerance ; entry was necessary to assure that the image calculates at the ; correct magnitude. ; ; I named the image "Over a Blue Horizon" because the greenish ; elements in the foreground appear to be floating over a hazy, ; more distant, bluish background. Then I bestowed a rating of 6 ; on the whole works. I could see no real reason to give a higher ; rating. ; ; The included parameter file finishes in 5 minutes on the fast ; machine and 22 minutes on the slow one. The time required to go ; to the FOTD web site at: ; ; ; ; and view the image already finished there is even shorter. ; ; Heavy overcast, with a chilly temperature around 55F 13C, light ; rain and a raw wind from the north made Wednesday an unpleasant ; day here at Fractal Central. The cats of the fractal variety ; needed a bit of extra petting to keep their spirits up. ; ; My day was boringly average, a situation that I actually found ; quite pleasant. The next FOTD will appear in about 24 hours. ; Until then, take care, and if everything is an illusion, then ; nothing, whatever nothing is, is having an illusion? ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Over_a_BlueHorizon { ; time=0:05:03.90-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=MandAutoCritInZ function=ident passes=1 center-mag=-0.02240988266139494/-0.000848508846262\ 04/2.054005e+012/1/97.5/3.878382e-005 params=-1/4/\ 1/1/0/0/0/0 float=y maxiter=600 inside=fmod outside=tdis periodicity=10 mathtolerance=0.05/1 colors=000UXAUTAUPAURAUTAUVAUXAUZAU`AUbAUdAUfAUhAU\ jAUlAUnAUmAUgAUdAPaAPbAPZAKVAFSA5PA0KA5PAAVAK_AUeA\ UkAcpAciAccAFfzJ`zNVzMTzMSzMQzMPzMOzMMzMLzMKzMIzMH\ zMGzQNzUUzY`zagzeizikzmkzqkzmpzjpzfuzcuz`yzXwzUvzR\ tzNrzKpzHozDmzAkz7jzAgzCezEczG`zIZzKXzMVzOSzQQzSOz\ UMzVIzVEzVAzTIzRPzPWzObzMizKpzJwzOuzTsz0zz1zz6yzBx\ zFwzKszPpzUnzaczhczJJzLOzNSzPXzR`zTdzVizXmzNDzcFzb\ Rz`Yz_dzZkzPjzUnzpmzlmzhmzdmz`mzXZzYbzYezYhzYkzYnz\ 7BzLXz5szPkzRlzSmzTnzUnzVozWpzXqzO`zNdzQgzSjzUlzWo\ z0vz4tzEszOczgFzfPzfTzfSzgRzfPzfNzjJzmEznLzlSziYzh\ `zf_zaYzXUzSKzOBzQKzSTzU`za`zWiz0Ez4Jz8OzDTzHYzLbz\ QgzUlzh_z5QzAUzEYzIazMezQizUmzFczJfzNizRlzVozRpzTp\ zUnzWpzXnzKpzNpzQpzTrzWozWpzXqzEwz0Az4Gz8LzDRzHWzL\ azQfzUlzMmzPnzSozVpz0GzATzMezdwzbuzatz_szZrzNzzTuz\ 0zzOPzTczYQzYVzY_zYczYhzYmzEkzHlzKmzNnzQozTpzWqzeW\ zeWzeWzfWzfWzfWzfVzfUzfTz } 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
