It is not Seahorse Valley, but ; rather the inside of the east branch of the valley enclosing the ; large southern period-3 bud. This valley has a name, though at ; the moment I cannot remember the name. ; ; The image has a maxiter of 200,000, and a logmap value of minus ; 31,250, but thanks to the speeded-up type=mandel formula and the ; efficiency with which the P2000 unit handles the speeded-up for- ; mula, today's image calculates in just a few seconds more than a ; minute. ; ; Coloring today's image presented a bit of a problem. With the ; logmap turned off, the image was too chaotic to be useful, while ; with a positive logmap value, the iteration bands were squeezed ; too far toward the low end. The negative value works reasonably ; well however, though even in this case, the bands are squeezed a ; bit too far toward the high end. ; ; With nothing of exceptional interest in the image, I rated it ; at a 7. The name "In a Hidden Valley" is not only poetic but ; describes the location of the image. The calculation time of ; just over one minute on my fireball computer is quite reason- ; able, but could easily leap to an hour or more on an older ; machine. ; ; All problems may be avoided however by viewing the finished ; image on the FOTD web site at: ; ; ; ; Incredibly spring-like weather in midwinter continued here at ; Fractal Central on Tuesday as the temperature reached 70F 21C ; along with bright sun and gentle breezes. The fractal cats ; noticed the pleasant conditions, then rolled over and went back ; to sleep. ; ; My day was busier than expected, but nowhere near hectic. The ; next FOTD will be posted in 24 hours. Until then, take care, ; and science assumes that the physical world is real, and science ; works very well, so why then do philosophers keep discussing the ; nature of reality? ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= In_a_Hidden_Valley { ; time=0:01:11.30-SF5 on P4-2000 reset=2004 type=mandel center-mag=-0.1197639246212\ 321/-0.6496272393531843/3.787523e+010/1/168.5/0 params=0/0 float=y maxiter=200000 inside=0 logmap=-31250 periodicity=10 colors=000_Yzj9MhANgAOfAPeAQdARcASbBSacz`cz_BVZBWY\ BXXBXZmz_IX`LXbOX000dUXfXXUWXhcXjfXk`XllXnoXorXpzX\ nrZmo`klbjjchgegdgebhd_jbXlaVm_SoZPqYNrXJiWFaVCTU8\ LT5Dl0yoAtrJouSkvPlvMmvJnwGowDowApx7qq4rt1rqChjT_c\ XRXZIzzUvwAmpAdlAZgBTaBTYBTVCURCUOCUKDUHDVDDVAEV6E\ V3EW4GX5HY6JZ7K_8M`9NaAPbBQcCSdKTeUVfUWgUYg_Zh_XiU\ WiUVjDUjCTkBSkARl9Pl8Om7Nr6Mv5Lz4Kz3Jz2Iv5Jr7Jm9Kh\ CKcEL_GLXJLULMSNMPQNMSNKUNPWJUXGYZDb_9ga6kb3la7l`A\ l_El_HlZKlYOlXRmXVmWYmV`mUdmUgmTkmSnmSq_`hMi_8qSFm\ TMiTSfUZcUecUkcVrcVxcVscYnc_icadcc_cfVchQcjLclGcnI\ coJcoKcpLhpNmqOrqPwrQxrRyrxzCtzDpzElzEizFezGazGZzH\ VzHRzIOzJKzJGzKDzKCzJCzIBzHBzGBzGPzaazvbzvazt`zs`z\ q_zpZznZzmWzlUzlRzlPzlMzlKzlHzdFzYDzRBzK9zDNzF_zHl\ zJyzLxzKxzKxzKxzKxzKxzKxzKwzKwzKwzKwzKwzKwzKwzKwzK\ pzHizEbzBWz8Pz5Iz2ezvcztazs`zrRzfHzW7zL8zR9zW9z`Az\ eAzjHzeNzaTzY_zTezPjzQjzO } ; END PARAMETER FILE========================================= ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
