An ; analemma is the figure-8 graph usually seen in the Pacific Ocean ; areas of world globes. At a single glance it shows the sun's ; declination and the equation of time for each day of the year. ; But there is little in today's image that resembles an analemma. ; The word simply seemed to fit the mood of the moment when I ; thought of it. ; ; The image itself resembles a solar eclipse more than anything ; else. Or some might see a steering wheel at the center. It is ; an unusual picture when compared to my standard routine of an ; unending string of images with decorated Mandelbrot midgets at ; the center. But since starting the tour of the Fractint ; formulas, I have done many images with no midgets, so maybe ; today's image is not so unusual after all. ; ; I created the picture by setting the single parameter to a ; rather high value of 240 and rendering the scene with the ; outside set to 'mult'. Apparently just for the fun of it, the ; 'mult' option colors the pixels by multiplying the iteration ; count of escaping points by their real divided by maginary ; values at the time they escape. ; ; The render time on my ancient worn-out machine is a nominal ; 12-3/4 minutes. This joins with the rating of 7 to give an ; overall worth of 55. For those who do not render, the image is ; available for download on the FOTD web site at: ; ; ; ; Those who download from the web site can ignore the overall ; worth. ; ; An off-and-on light rain fell all day Wednesday here at Fractal ; Central. The rain did not amount to much, but it was enough to ; keep things wet and keep the fractal cats confined indoors. ; Luckily we were well stocked with tuna. Today is starting ; partly cloudy and quite mild, but showers are in the area, and ; the wind is rising. The cats have yet to pass judgement on the ; conditions. ; ; In my department the work is caught up and I have little to do ; for the rest of the day but take it easy. So far I have heard ; nothing about being invited to any dinners. Unless something ; changes, this will leave me plenty of time to find the next ; fractal. Until that next fractal appears, which will happen ; right here in 24 hours, take care, and then take further care. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Analemma { ; time=0:12:47.53--SF5 on a P200 reset=2004 type=newton passes=1 center-mag=0/0/0.1\ 261867 params=240 float=y maxiter=7500 bailout=9 inside=0 outside=mult logmap=yes symmetry=origin periodicity=10 colors=000000zzzzzzzm4zm6zm7zm8tKgrMhqNhpPhoQhnShl\ TikVijWiiYihZif`jeajdcjcdjbfj`gk_ikZjkYlkXmkYljZkj\ Zjj_ij_hj`gjagjafjbejbdjccjcbjdajeaje`jf_jfZigYigX\ ihXiiWiiVijUijTikSikRilRimQimPinOinNioMisKjqLipLio\ MinMhmNhlNhkOgjOgiPghPggQffQfeRfdRecSebSe`Te_TdZUd\ YUdXVcWVcVWcUWcTXbSXbRYbQYaPZaOZaN_`M_`K``J``Ia_Ha\ _Gb_FbZEcZDcZCdZBdYAeY9eY8fX7fX6gX3iW4hX4hX5gX5gX6\ fY6fY7eY7eY8dY8dZ9cZ9cZAbZAb_Aa_Ba_B`_C`_C_`D_`DZ`\ EZ`EYaFYaFXaGXaGWaGWbHVbHVbIUbIUcJTcJTcKScKScLRdLR\ dMQdMQdKSbLRcMQdMQeNPeNPfOOgOOhPNhPNiQMjQMkRLkRLlS\ KmSKnTJnTJoUIpXHtWIrVIqUIpTInSImRIlQIjPIiOIhNIfMIe\ LIdKIbKIaJI`IIZHIYGIXFIVEIUDITCIRBIQAIP9IN8IM8ILAH\ NCGPEFRGETIDVJCWLBYNA_P9aR8cP4fS7dUAbWC`YF__HYbKWd\ NVfPThSRkTSjURjURjUQjUQjUQjUPjUPjVOjVOjVOjVNjVNjVN\ jVMjWMjWLjWLjWLjWKjWKjWKjXJjXJkYKlZKm_Kn`KoaKpbKqc\ KrdKseKtfKugKvhKwiKxjKykK } ; END PARAMETER FILE========================================= ; ;
