Actually it's ; simply a Julia version of the FinDivBrot-2 formula. Today's ; image is the first one I found with the new formula, and it ; rates FOTD status. I cannot recall this ever happening before. ; ; The 'comet' with the long, long tail that streaks across the ; entire frame is actually a complete Julia set, one of the most ; unlikely Julia sets I have yet stumbled upon. The corresponding ; Mandelbrot fractal is a Mandeloid with everything scrunched ; around toward the main stem, and the east side of the main bay ; cut off by a straight wall. Today's image corresponds to the ; point where the curving north shore line meets the straight wall. ; ; The image resembles a comet zooming across the sky. (In fact, ; comets do not zoom across the sky except in the movies.) I ; rated the image at a 7, which is above average. The colors are ; quite smooth, and it has some math interest, all of which add to ; its worth. ; ; The name "Cometary Residue" came about when I turned the image ; upside down. It originally was rotated 180 degrees from its ; present orientation. ; ; The coloring smoothness was achieved by rendering the image with ; the outside set to 'tdis', which colors the points according to ; how far they travel before escaping. ; ; The calculation time of under 2 minutes is not too high a price ; for the result, but all calculation may be avoided by viewing ; the finished image on the FOTD web site at: ; ; ; ; Partly cloudy skies, a temperature of 88F 31C, lower humidity ; and a refreshing breeze made Thursday quite an acceptable day ; here at Fractal Central. The fractal cats came out of hiding ; long enough to get into a squabble over who would spend the ; afternoon on the foot stool. ; ; My day was satisfactory, as far as that goes. And if all goes ; well, tomorrow will be a repeat. With the drought growing worse ; here in Pennsylvania, FL is concerned with her garden, but so ; far, with generous watering, the plants appear to be holding up ; rather well. The next FOTD will be posted in 24 hours. Until ; then, take care, and be satisfied. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Cometary_Residue { ; time=0:01:50.09-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=FinDivBrot-2J function=recip center-mag=10.892/-14.7808/0.052083/1/90/0 float=y params=1/1/10000/0/0.79606/0.19699 periodicity=0 maxiter=5000 inside=255 outside=tdis symmetry=none colors=000zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzMzzNzzNzzOzzOzzPzzPzzQzzQzzRzzRzzSzzSzzTzzT\ zzUzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzbzzbzzczzczzdzzdzzezzezzfzzfzzgzzgzzhzzizzizzjz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzASsASsBSrBSrBSqCSqCSpCSpDSoDSoDSnDS\ nESmESmESlFSlFSkFSjGSjGSiGSiHShHShHSgHSgISfISfISeJ\ SeJSdJSdKScKScKSbLSaLSaLS`LS`MS_MS_MSZNSZNSYNSYOSX\ OSXOSWPSWPSVPSVPSUQSTQSTQSSRSSRSRRSRSSQSSQSSPTSPTS\ OTSOTSNUSNUSMUSMVSLVSKVSKWSJzzJzzIzzIzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz9zz8zz8zz7zz7\ zz6zz6zzzzzzzzzzzzzzzzzzzzzzzzzzzzz4zz4zz5zz5zz6zz\ 6zz7zz7zz8zz8zz9zz9zzAzzBzzBzzCzzzzzzzzzzzzzzzzzzz\ zzzzzzzGzzHzzHzzIzzJzzJzzKzzKzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzTzzUzzUzzVzzVzzWzzWzz\ XzzXzzXzzWzzVzzUzzTzzSzzz } frm:FinDivBrot-2J { ; Jim Muth z=pixel, c=(p3), a=-(real(p1)-2), esc=(real(p2)+16), b=imag(p1): z=(b)*(z*z*fn1(z^(a)+b))+c |z| < esc } ; END PARAMETER FILE========================================= ; ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
