Perhaps I exaggerated a ; bit when I named it "Attack of the Spiral", but some of its ; nooks look absolutely threatening, not to mention its crannies. ; ; The image rates a 6, which is equal to an old rating of a 7. ; This is the last day I will list both the new and old ratings. ; >From now on I will simply list the new rating. But remember ; that images with new ratings will usually appear better than ; expected. ; ; For some reason I tend to avoid spirals, perhaps because they ; are so trendy, especially with contest participants, but occa- ; sionally, as happened today, even I fall prey to the temptation ; to check a spiral for hidden goodies. The goodies in today's ; image are not exactly hidden however. They are there on the ; surface for the whole world to see. ; ; The parent fractal came about when I calculated the Z^(1.5)+C ; Mandeloid as it appears 0.5 levels up the complex logarithmic ; hyperspiral when no function is applied. This parent fractal ; appears as a Mandeloid rotated so that its main bud faces north. ; Both its main bay and main bud are squashed, with a lively broad ; spiral extending from the northeast shore line of the main bay. ; Today's scene is located at only a small depth in this broad ; spiral. ; ; The calculation time of 34 seconds is surprisingly fast. The ; finished image may be viewed without the task of calculation, on ; the active FOTD web site at: ; ; ; ; The original classic FOTD web site may be accessed at: ; ; ; ; My own web site may now be accessed at: ; ; ; ; but the site is still in the early stages, and today's FOTD will ; not be posted for a day or so. Suggestions for improvement will ; always be considered, so feel free to make helpful comments. ; You might also check FL's puzzles on the site. She deserves a ; little return for all the work she has done helping to get the ; web site up and running. ; ; With a high temperature of 81F 27C, Monday was the warmest day ; of the spring so far here at Fractal Central in central Pennsyl- ; vania. In fact, it was warmer outside than inside. The fractal ; cats considered the temperature just right, but their relation- ; ship must have left something to be desired. In the evening ; they were spotted at opposite ends of the fractal hallway in ; full sulk posture, their sulks directed at each other. ; ; The day of the humans was busier than expected. Most of the ; extra work involved making last minute tweaks to the FOTD web ; page. The next FOTD image is due to be posted in 12 hours or ; so. Until then, take care, and what will be, will be, but we ; don't have to sit down and helplessly take whatever comes. ; ; ; Jim Muth ; jamth@mindspring.com ; ; ; START PARAMETER FILE======================================= Atack_Of_TheSpiral { ; time=0:00:34.77-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=MandelbrotBC3 function=ident passes=1 center-mag=+0.76882629/+0.54538622/266/1/180 params=1.5/0/0.5/0 float=y maxiter=288 inside=255 logmap=27 periodicity=6 colors=200LNUKMTJLSIKRHJQGIPFHOEGNDFMCELBDKADJ9CI8\ BH7AG69E68D56B44955B57D58F5AH5BJ5DL5EN5GP5HR5JT5KV\ 5MX5NZ5P`5Qb5Sd5Tf5Vh5Wj5Yl5Zn5`p5ar5ct5dt5ft5gt5g\ t5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5gt5\ lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5lt5qt\ 5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5q\ t5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5\ qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt\ 5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qt5qtBqt9qt7qt5q\ t9qtBqtDqtFqtHqtJqtLqtNqtPqtRqtTqtVqtRmtRmtRmtRmtR\ mtRmtRmtRntRntRntRntRntRntRntQptRotRntRmtRltRltRkt\ RjtRitRhtRhtRgtRftSesSesSdsScrSbrSarSaqS`qS_qSZpSY\ pSYpTXoTWoTVoTVnTUnTTnTSmTRmTRmTQlTPmTOmUNmTOmTOmT\ PmTPmTQmTQmTRmSRmSSmSSmSSmSTmSTmSUmSUmRVmRVmRWmRWm\ RXmRXmRXmRYmQYmQZmQZmQ_mQ_mQ`mQ`mP_mQ`mQ`mQ`mRamRa\ mRamSbmSbmSbmTbmTcmTcmUcm } frm:MandelbrotBC3 { ; by several Fractint users e=p1, a=imag(p2)+100 p=real(p2)+PI q=2*PI*fn1(p/(2*PI)) r=real(p2)+PI-q Z=C=Pixel: Z=log(Z) IF(imag(Z)>r) Z=Z+flip(2*PI) ENDIF Z=exp(e*(Z+flip(q)))+C |Z|
