The reason for the name will be ; obvious as soon as the image is seen, and with a calculation ; time of 1-1/4 minutes, the wait will not be long. ; ; The parent fractal is a degenerate Mandelbrot set. Today's ; scene is located some distance east of the remains of the East ; Valley of the parent. Little East Valley stuff remains in the ; image, though a few hints appear here and there. ; ; Surprisingly, the image is extremely sensitive to changes in the ; escape radius, imag(p3), which in the image is the formula ; default of 100. As the escape radius is increased or decreased, ; the image changes dramatically. It evaporates and vanishes ; entirely when the value of imag(p3) is increased to about 8500. ; When imag(p3) is set to -13.92, the image takes the shape of a ; Maltese cross. Any negative value greater than this gives a ; blank screen. ; ; Before experimenting with the escape radius however, be warned ; that the calculation time increases dramatically as the ER is ; increased. When imag(p3) is set to substantially greater ; values, the calculation time increases to more than 15 minutes. ; ; At an escape radius of over 8500 or so, the result is a blank ; screen consisting totally of 'inside' stuff. But even here all ; hope is not lost. Using an active inside fill such as 'bof61' ; brings the blank screen to life. But here again, the calcula- ; tion time grows even longer. ; ; The rating of a 7 seems about right. Calculation may be avoided ; entirely by viewing the finished image on the FOTD web site at: ; ; ; ; Near perfect outside conditions kept the fractal cats happy here ; at Fractal Central on Friday, even though they are inside cats. ; Partly cloudy skies, low humidity and a temperature of 79F 26C ; are near perfect by any human's or any cat's standards. In my ; area, the rush died out in the morning, followed by a slow ; afternoon. The next FOTD will be posted in 24 hours. Until ; then, take care, and don't be caught with your fractals down. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Pits_and_Bieces { ; time=0:01:15.73-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=MandAutoCritMinZ function=recip center-mag=+0.2794802820587657/+0.0280646118234618\ /6.298586e+008/1/180 params=1/1/3/-1/0/0/0/0 float=y maxiter=1500 inside=0 periodicity=6 colors=000mVHsPGxHCzCAz68z06``P0ze4zkGsoRks`dvkXzv\ PzzHzzAzzAvzAizAVzAHxA2vA0o00i00b00X000Eu0AmA6eP4Z\ HLeAbk2ss0zx0zzJzskzgzuZCXz6Xz2Xz0Xz0Xz0Xz0Xz0RzCN\ zPJzbGziPzqXzvdqzeezgVzgJzi8zi0zk0zk0zb0kT0VJ0EC0C\ C4ACNACe2Eg0Ei0Gk0Gm0Gm0Ag06d00`00V00R00N00T00Z00b\ 42gA6mGAqLEvRGzzzvzsuqdugPuZ8uP0uG0uoLo0LV0RX4VXH`\ ZTdZegZsm`zq`zu`mxiJzq0zxkxqdovZezRXzLNzGGzdPzzZzz\ gzzixiiqPki6kb8bXAVRALNCEHE6CE08G02G00N0C000`0Ze0i\ k0ui0mg4ggXbebXedRdeLdgGXiERkEJiEEgE6eE0dETbC0bk0L\ T0C8026006004004000000400E00N00X00e00o0Tq0Tz00z0Tz\ PTz8TzUTvRTs`Tzd0zf0zh0zjCzpEzsExuEzz0izE`zTKuzLzz\ XuzezzouzxzzzzzzzzzzzzzzzzzzzzzzzgzzdzzNzz8mT0ZT0J\ TTPTzzzzkzxgzqeziizbmzv`ozP`zXdodebkgPszCzk0zm0zo0\ mk0Pg00d00b00gH0mb0sv0xz0zz0sz0iz0`z8RzGHzN8xV0v`0\ 4z0Cz0JuARmJZeTeZbmRkuJuzEzqkZgz2izEkzPmzZoziqzusz\ zuzzZv4XsAVqGToLTmP`eLe`J } frm:MandAutoCritMinZ {; 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 ;
