This orientation results when the imag(z) ; axis is perpendicular to the Mandelbrot plane and the resulting ; three-dimensional slice of the Julibrot is cut in a horizontal ; direction parallel to the top of the desk. ; ; Real(z) and/or imag(c) must be set a bit above or below zero, or ; else the slice misses Seahorse Valley, passing through the space ; between the two branches. In today's case, both values are set ; to 0.06, which eliminates X-axis symmetry in the parent fractal. ; ; In this parent, Seahorse Valley appears as a bridge between the ; north and south shores. Two micro-thin hairlines lie on the ; west edge of the bridge, with today's scene lying in the thinner ; hairline closer to the main body of the valley. These hairlines ; are actually parts of Seahorse Valley sub-buds seen from the ; side. ; ; A look at the crazy values in the parameter file will show that ; today's image was hugely stretched and skewed to bring it to a ; recognizable appearance. In fact, I did no actual skewing, but ; the rotating and stretching I did has the same effect as skewing. ; ; I rated the image at an 8. This includes a full point for the ; coloring, which turned into a study of getting smooth colors ; from a 256-color palette. The unusual in-to-infinity-and-out- ; again spiral accounts for the other 7 points. ; ; The calculation time of 6-3/4 minutes is barely within reason, ; so why not take a scenic trip to the FOTD web site at: ; ; ; ; and save the minor effort of setting up this letter so that it ; will run as a Fractint parameter file. ; ; The Friday weather was uneventful here at Fractal Central. The ; partly cloudy skies and temperature of 81F 27C were so close to ; normal that little else need be said. The fractal cats slept ; through most of the non-action. ; ; Meanwhile, my day was also close to average, and with any luck, ; tomorrow will be the same. The next FOTD is due to be posted in ; 24 hours. Until then, take care, and live in peace with ; fractals. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Seahorse_Valley-13 { ; time=0:06:44.61-SF5 on P4-2000 reset=2004 type=formula formulafile=basic.frm formulaname=Elliptic center-mag=-0.756516862636129\ 8/-0.3556880339637087/4.796564e+007/0.0006617/89.9\ 81502659185395/-89.0184738672499662 params=0.06/0/\ 0/0.06 float=y maxiter=15000 inside=255 logmap=2708 periodicity=10 mathtolerance=0.05/1 colors=000SEtTFtUGtVHsWIsXJsYJsZKr_Lr`MraNrbOqcOqd\ PqeQqfRpgSpgTqhTrgUrfVqeXpdYocZnb_ma`l`ak_bkZckYdk\ XekWfkVflUflTflSfkRfkQfkQfkQelRelTemVemXdnYdn_dnad\ occoecpfcphcqjbqlbqnbrpbrrastasvatwatwarw`qw_pv_nv\ ZmuZkuYitXgtXfsXdsXbsY`rY_rZYqZWq_Up`TpaRobPocNocM\ ocNncOmcPlcQkcRicSgcTedUceXafZ_g`YgcYfeZeg`ejadlbc\ nccpbboabnabm`bl`ak_ajZaiZahYagY`gX`fX`eW`dV`cV_bU\ _aU_`TZ_UY`TY_TXZTWYTVXTUWTSVTRUSPTSNSSMRSKQSJPSHO\ SGNREMRCLRBKR9JR8IR6HR5HQ6IQ7JP8KP9LOALOBMNCNNDOME\ PMFPLGQLGRLHSKITKJTJKUJLVIMWINXHOXHPYGQZGR_GR_HQ`I\ PaIObJNcKMdKLeLKfMJgMIhNHiNHimTGoTEzmDzTBzmAzUBzmB\ zUCzUCzmCzUDzmDzUEzmEzUEzmGzZIzmKzzLzdNzuPzhRzuSzl\ UzuWzpYzuZzt`zubzsdzuezuczrbzuapj_ngZlcYj_XhWVfSUd\ PTbLS`HQZDPX9OV3JW6NW8RWBVXDZXGbXHdXIeYMdZQdZUd_Xd\ _`d`ddahcakcbocbsccwcczcbyaay_`yZ_yXZyVYxUNCmLCnJB\ pHBrFAtB9vDAuEBuGCuHDuJEt } frm:Elliptic {; Jim Muth imag(z),real(c) z=flip(imag(pixel))+p1, c=real(pixel)+p2: z=sqr(z)+c, |z| <= 16 } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
