I needed to go ; back to version-4 because it allows control over the bailout ; radius. Today's image uses a negative exponent of Z, and nega- ; tive powers of Z create fractals that tend to evaporate at very ; large bailout radii, such as the one-million of the version 5 ; formula. ; ; The parent fractal is a variation of the Z^(-3)+C Mandeloid, ; with a Mandelbrot set lying in the sandy fractal stuff at its ; center. Today's scene is located in an elephant-trunk spiral in ; the East Valley of this Mandelbrot set. ; ; The sandy stuff filling this area of the parent has infested the ; entire image, rendering the typical East Valley pattern almost ; invisible. Only the broad but careful coloring makes the spiral ; pattern visible. ; ; I named the image "Sand Castles" after the overall sandy effect. ; I rated it at a 7 because . . . well, I think it's worth it. ; ; The calculation time of 2-2/3 minutes makes the job of running ; the included parameter file, if not a gale, at least a breeze. ; And I'm not blowing hot air when I say that the finished image ; is available on the FOTD web site at: ; ; ; ; Absolutely perfect weather conditions prevailed here at Fractal ; Central all day Thursday. The deep blue sky and total sun were ; made even more enjoyable by a temperature of 79F 26C and the low ; humidity. The fractal cats must have agreed, for they got into ; a minor squabble over who would sleep in the spot of sunlight on ; the living room floor. ; ; My day was satisfactory. Tomorrow should be the same. The next ; FOTD will appear in 24 hours. Until then, take care, and the ; world is what you make of it. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Sand_Castles { ; time=0:02:41.15-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=DivideBrot4 passes=1 center-mag=+0.04014873876952896/-0.000578747776991\ 23/1.679661e+008/1/177.5/0 params=-3/0.15/-90/0 float=y maxiter=5000 inside=0 logmap=172 periodicity=10 mathtolerance=0.05/1 colors=020IQzIQzISzIUzIUzIWzIZyIZyI_yIavIdvIdtIftI\ htIhrIirnktwkzwnzmpzIpzIrzItzItzIwzIyzIyzIzzIzzMzz\ KzzIzzIzzGzzGzzEyzEyzCwzCtzAtzczzczz7wz7nz5kz5kz3i\ z3hw1hs1fq0do0dn0am0_l0_k0Zi0Wg0We0Uc0Sa0S_0QY0OW0\ OU0MU0KU0KU0IU0GU0GU0Ez0Cz0Cz0Bz09z0Bz09z09z09z09v\ 07r07m07h07c05Z05U05R05O03M03K13I33G52C72A827A25C2\ 3E25E25E25G25G27G27G27I27I27I28I28K28K28K2AK2AM2AM\ 2AM2AO2CO2CO2CO2CQ2EQ2EQ2EQ2ES2ES2GS2GS2GU2GU2IU2I\ X2IX2IX2IX2KY2KY2KY2KY2M_2M_2M_2MX2UY2QY2O_2M_2Kb2\ Ib2Gb2Ed3Cd5Ae98eB7gC5gE3gG1jI0jK0lM0lO0nS0nU0nW0p\ Z0p_0ra0rd0tf0th0nr0pn0rk0ti0vh0yf0zd0zf0zh0zi0zk0\ zn0zp0zr0zt0zw0zy0zz0zw0zr0zn0zi0zf0zf0zf0zf0zf0zf\ 0zf0zf0zf0zf0zf1zf1zf3zf5zf7zf7zf8zfAzfCzfGzfEzfCz\ fCzfAzfAzf8zf8zf7zf7zf5zf5zf3zf3zf1zf1zf0zf0zf0zf0\ zf1zf1zf1zf3zf3zf3zf5zf5zf5zf7zf7zf7zf8zf8zf8zfAzf\ AzfAzfCzfCzfCzfEzfEzfEzfG } frm:DivideBrot4 { ; Jim Muth z=0, c=pixel, a=real(p1)-2, b=imag(p1), d=real(p2)+100: z=sqr(z)/(z^(-a)+b)+c |z| < d } ; END PARAMETER FILE========================================= ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
