The name "Dissolution" refers back to this ; unseen parent fractal. ; ; Today's scene is located on the shattered remnants of the once- ; mighty negative stem, not too far east of the once-prominent ; large minibrot, but far enough that most of the typical East ; Valley stuff has disappeared. The few remnants that do remain ; add a modicum of interest to the central minibrot. ; ; The rating of a 6 is what I think the image is worth. The ; rating is held down by the coloring, which could use a bit more ; work. As it is, I had too little time to devote to bringing out ; the scene's full potential. ; ; The calculation time of just under 3 minutes will pass in a slow ; flash for those running the included parameter file. The trip ; to view the finished image on the FOTD web site at: ; ; ; ; will pass in a fast flash. ; ; Clouds moved in overnight Sunday here at Fractal Central, lead- ; ing to a cloudy day Monday with a temperature of 41F +5C and a ; few spurts of tapioca snow (graupel). The fractal cats took the ; whole thing in stride, dividing their time between the heat and ; their window shelf. My day was boringly busy. ; ; It was reported on the list that the FOTD images were quite suc- ; cessful when I created them with the formulas hard coded in the ; Fractint program. I'm not sure I totally agree, but who knows ; -- maybe I'll have another go at those surprisingly simple yet ; productive formulas. The next FOTD will be posted in 24 hours. ; Until then, take care, and listen close to today's music if you ; want to know what's wrong with the world. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Dissolution { ; time=0:02:58.23-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=MandAutoCritInZ function=ident passes=1 center-mag=-1.616933041801702/-0.2780341565794527/\ 1.3e+010/1/22.5/0 params=1/2/2/0.9/0/0/0/0 float=y maxiter=1500 inside=0 logmap=176 periodicity=6 colors=000KEKLFKMGKNHKOIKPJKQKKRLIXMGbNEhOBmP8rVKv\ _UzdczjmzorztvzzzkxzcwzWvzOuzHuzKswMqrPpmRnhUgcWaZ\ ZVU`P6XRKUTYRZjw0EqDJkSNebS`lWKsQ4zK8wRBtXFrbIohMm\ nPjtShzsFctFdtFeuFeuFfvFgvFgwIawLWwNQwQLwSFwV9wX4z\ mDzrMzmQzRUzKYlE`eJX_OTTSPNXLG`HAeD4i9Fe8Pb7__6iX5\ sU4fzQbsU_lYXeaUZeRThK`bChX5pS4qX4r`3rd3si2tm2tq6r\ p9ppCnpFlpIjoMhoPfoSeoVcnYana_ndYngWmjUmmSmpRmoSnn\ TonTpmUqmVrlVslWtkXujXvjYwiZxiZyh_zh_zjbrkdkmfcniX\ pkPqmImjKjgLfdMcaN_ZPXWQTURQRSMOUJLVFIWCFX9DYYUkvi\ yrgtnfojdkgcfcab_`YX_UUYWSWXQUYOT_MR`JPaHNbFMdDKeB\ If9HgCGhFGiHGjKGkMGlPGmSGnUFoXFpZFqaFrdFsfFtiFukFv\ OKVWPVbUVdXZfZbh`fjbildmnfqphuqjxpkwYVGXVMWVSWVYaW\ ZgX_mX_sY`xY`u`_scZpeZnhYljYYNIK02mb7kb6ib5gb4ee4c\ h3ak2_n1Yq1btCgwNlzXizYgzZdz_bz_czYczWczUczSczQfzR\ hzSjzSlzTnzTpzUrzUfzTVzdKzo9zzLzWWz2TzCQzMNzWLzdTz\ X`zQhzIpzBxz4jzJKz9JjBIzC } 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
