While searching for a name, I ; noticed the row of arches across the bottom of the image, and ; was reminded of the railroad bridge across the Susquehanna River ; at Marysville, which is just north of Harrisburg. ; ; The slice is centered at the western limit of the ever-smaller ; string of buds lined up out the negative X-axis of the Mandel- ; brot set. The orientation is at an angle rotated 31 degrees ; from the Parabolic toward the Oblate, though mostly Parabolic ; elements predominate. ; ; The rating of a 6 means I am only mildly impressed by the image, ; though, because of the spectacular coloring, I do consider it ; worth nominal FOTD status. ; ; The very brief calculation time of 8 seconds assures that very ; little effort will have been wasted if the resulting image lays ; an egg. ; ; To avoid the possibility of ending up with an omelet, I suggest ; checking to see if the image is posted on the FOTD web site at: ; ; ; ; After a heavy overnight thunder-storm, Wednesday dawned cloudy ; and blustery here at Fractal Central. The conditions continued ; most all day, with the clouds breaking only long enough to give ; a glimpse of the setting sun. The winds made the temperature of ; 52F 11C seem surprisingly chilly. The fractal cats made the ; most of things, checking every so often to be sure no unwanted ; cats were prowling nearby. ; ; My day was slow enough to enjoy, but not so slow as to cause ; concern. The next FOTD will be posted in 24 hours. Until then, ; take care, and be ever so cautious when the aliens from Sirius C ; are snooping about. They're as sneaky as a cat. ; ; ; Jim Muth ; jamth@mindspring.com ; ; ; START PARAMETER FILE======================================= Stone-Arch_Bridge { ; time=0:00:08.27-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=SliceJulibrot2 center-mag=0.572006/\ -0.350829/0.7022955/1/121/0 params=0/90/31/31/\ -1.40115519/0/0/0 float=y maxiter=950 inside=255 logmap=yes symmetry=none periodicity=6 passes=1 colors=00000A00C01E02G03I34K55M76O87RC8UF9WHAWIBYJ\ C`KDbKFeLGhNHjOImQJpSKtTLwVMyWNzVPxVRvUStUUpTVnTXk\ SZhS_zRazRbzQdzQfzPgzPizPjzOkzOlzOmzOmzOmzOmzNmzNm\ zNmzNmzNmzNmzNmzPmzRmzTmzUmzWmzYmzZmz`mzbmzdmzemzg\ mzimzjmzlmznmzomzgmz_mzTmzLpzEtzHszJrzMqzOqzRpzToz\ WozYnz`mzbmzemzgmzjmzlmzomzqmzpmzpmzpmzpmzpmzpmzpm\ zpmzpmzpmzpmzpmzpmzpmzpmzqmzqmzqmzqmzqmzqmzqmzqmzo\ mzmmzkmzimzgmzemzcmzamz_mzYmzWmzUmzSmzUmzVmzXmzYmz\ _mz`mzbmzcmzemzfmzhmzimzjmzlmzmmzomzpmzrmzsmzumzvm\ zxmzymzzmzxmzvmzumzsmzrmzpmznmzmmzkmzjmzhmzfmzemzc\ mzbmz`mz_mz`mz`mz`lz`kyajxaiwahvaguafubfubfvbfvbfv\ bfwcfwcfwcewcexcexdexdeydeydeydeyfmxgmwimvjmulmtmm\ tjmjgmaemTbmK`mB`mN`mY`mhamkammbgoblqakp`jo`in_in_\ hmZglYglYfkXejXejWdiWchVchUbgUmfTmfTmeSmdSmdPmeNme\ LmfImfGmfEmgCmg9mg7mh5mh3mh3mh3mi3mj3mk3mk3ml3mm3m\ n3mn6ml9mjCmhFmfImdLmbszz } frm:SliceJulibrot2 {; draws most slices of Julibrot pix=pixel, u=real(pix), v=imag(pix), a=pi*real(p1*0.0055555555555556), b=pi*imag(p1*0.0055555555555556), g=pi*real(p2*0.0055555555555556), d=pi*imag(p2*0.0055555555555556), ca=cos(a), cb=cos(b), sb=sin(b), cg=cos(g), sg=sin(g), cd=cos(d), sd=sin(d), p=u*cg*cd-v*(ca*sb*sg*cd+ca*cb*sd), q=u*cg*sd+v*(ca*cb*cd-ca*sb*sg*sd), r=u*sg+v*ca*sb*cg, s=v*sin(a), c=p+flip(q)+p3, z=r+flip(s)+p4: z=sqr(z)+c |z|<=9 } ; END PARAMETER FILE========================================= ; ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
