Today's image lies ; in a field of debris just east of the 'fan'. ; ; I gave the image no name or rating. Due to the winding-down but ; still pressing rush, I gave the image too little time and effort ; to honor it with a name. I might have rated it at a 4 or 5, but ; decided to let it go un-rated. ; ; The calculation time of 3-1/2 minutes means that little time ; will have been wasted if the image disappoints. And almost no ; time will have been wasted if the image is viewed on the FOTD ; web site at: ; ; ; ; In a few days I will discuss the use of the MandelbrotMix4 ; formula, paying special attention to the method I use to find ; good parameters to enter into it. But to begin the discussion ; right now, I might re-phrase the question into something like, ; "how do I recognize a good parent fractal when I see one?" ; ; A cooler but still mild day with a temperature of 59F 15C here ; at Fractal Central on Wednesday went un-appreciated by the ; fractal cats. They were more interested in watching the local ; squirrels make more squirrels. In my department the work is ; almost back to the normal amount. One or two more days should ; just about do it. The next FOTD will appear in 24 hours. Until ; then, take care, and be of sound mind and body, but don't make ; too much noise while you're doing it. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= FOTD_for_Mar_29_07 { ; time=0:03:32.45--SF5 on a P200 reset=2004 type=formula formulafile=allinone.frm formulaname=MandelbrotMix4 function=recip passes=1 center-mag=+7.81582291647887900/+0.263607712474751\ 30/249.6664/1/25/1.13533467349657968e-010 params=-5/-1.1/-0.1/-11.1/0/0 float=y maxiter=750 inside=0 logmap=49 periodicity=10 colors=000WLuZJv`GyZIxYJxWLxVMxTNxSPxQQxPSxNTxMUxK\ VxJXxIUxHVuGUrFQoERlDMiCJfBHdAFa9CZ8AW78T65Q03N01L\ 04IA6FA8CIA9SC6WE3_G1cL4hP7mT9rXCv`EzeHziKzmMzqPzu\ RztUztczzmzzzzzzzzmztcztUvtTqjPlaLgTIbKEZBBRI8JP6B\ W44z25z66zA7zE8zH8zL9zPAzSBvWCr_CmbDhcEccFZdFUdGPd\ HKeIFeIAfJ8fK9fL9gLAgMAhNBhNBhMCeMDbME`LEYLFVLGTKH\ QKHNzzLJJIzzFJKDzzAIM7zz5vz9rzCmzFhzIczLZzOHjRKfWM\ b_OZcRVgTRkVNoXJsVNqURpTUoSYmRalQdkPbjPajP`iP_iPZh\ PYhPXhPWgPVgPUfPTfPSePRePQeELwDMtDMqDNnDNkDOhDOeCP\ bCP_CQXCQUCRRCROCRLDSODSRETUETXFU_FUbGVeGVhHWkHWnJ\ XmLXmMXlOYlPYkRYkTZjUZjWZiX_iZ_h__ha`db`ac`YeaVfaR\ gaOhaLgeHghDPVV6Hl7Km8Nn9QoATpAWpBZqCarDdsEgtEjtFm\ uGpvHswHuwKvxNwyPxzSyzVzzXzz_zzbzzdzzgzzizzjzzjzzj\ zzjzzkzzkzzkzzkzzkzzhzzfzzczzazzZzzXzzUzzSzzPzzNzz\ LzzJzzHzzFzzDzzBzz9zz7zz5zz4zz9zzDzzHzzLzzPzzIzzGz\ zEzzCzzFzzIzzLzzOzzQzzTzz } frm:MandelbrotMix4 {; 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, 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
