Normally, I find the FOTD names ; almost automatically as I study the images (yes, this sometimes ; produces duplicate names). But after studying today's image for ; nearly 1/2 hour, and finding no satisfactory name for it, I ; finally decided to identify the image by giving it the name of ; the date on which it appears. (If I had done this with all the ; past FOTD images, I would have a far easier time identifying and ; finding them.) ; ; I used the 'fn+fn' formula built into Fractint to create today's ; image. Like the recent formulas that use the Fractint ; functions, this formula can draw a vast variety of fractals. ; Not all of the possible fractals this formula can create are ; useful however, but many are quite interesting. To create ; today's image, I chose to combine 0.4 imaginary part of cosxx(Z) ; with 0.4 imaginary part of sqr(Z). (The cosxx function is not a ; legitimate math function. It is a coding error that appeared in ; an early version of Fractint, but drew enough interesting ; fractals to make it worth keeping in the program when the error ; was corrected.) ; ; To add some extra life to today's image, I rendered it with the ; outside set to 'atan' and the inside set to 'bof61'. ; Surprisingly, the maxiter of the image, which is 95, has a great ; effect on its appearance. As the maxiter is increased, the ; foreground objects grow rapidly larger, until the greyish-blue ; background is soon filled in, resulting in a more detailed, but ; IMO less interesting image. (I am one of those who appreciates ; vast empty spaces.) ; ; Maybe if I had found a proper name for the image, I would have ; rated it at a 6. But the fruitless search soured me on it, and ; in the end, all I could give it was a rating of an average 5. ; The humdrum rating really surges to life however when the almost ; instant render time of 4 seconds is considered, resulting in an ; overall worth of a shocking 5822. ; ; The completed GIF image is or soon will be available on the FOTD ; web site at: ; ; ; ; A sunny but rather chilly day here at Fractal central on Sunday ; made for rather cool cats. The duo prefers a temperature above ; the 57F 14C, which was as warm as it got on Sunday. They showed ; their displeasure by demanding (and getting) an extra serving of ; tuna. Today is starting just as cool. The cats might turn even ; cooler. Lckily, we have a lot of tuna in the cabinet. ; ; My next task is to find a cool fractal. Since the number of ; fractals is infinite, my chance of doing so must be 100 percent. ; But somehow, it just doesn't seem to work out that way. I'll be ; back here in 24 hours with a cool fractal. If I can't find a ; cool one, I'll have a hot one. Until then, take care, and don't ; lose your cool when you see a hot fractal. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= October_18_2004 { ; time=0:00:04.12--SF5 on a P200 reset=2003 type=fn+fn function=cosxx/sqr float=y center-mag=-4.4938/4.17348/1.670533/1/25/-1.233735\ 33611e-014 params=0/0.4/0/0.4 maxiter=95 bailout=64 inside=bof61 outside=atan logmap=yes periodicity=10 colors=000Y`hWksXnzYjsZdv_is`isahsbgscgsdfsefsfesg\ eshdsicsjcskbslbsmasnaso`sp_sq_srZssZstZsucsthgtmX\ srMswBsm0mcDgaQacaWenQfzPcvOasO_pNYmMWjMUgLSdLQaKO\ ZJMWJKTILQINNHPKGRHGTEFVBFX8EZDE`HDbLDdQCfUChYCjbB\ lfBnjApoArsAsuBruBptCnrClqDjpDhnDfmEdkEbjF`iFZhFXg\ GVfGTfHSeHRdIQcIPbIOaJN`JM_KLZKKYKJXLIWLHVMIU00000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 00000000000000000000000000000000000000000000000000\ 0000000000000000000000000 } ; END PARAMETER FILE========================================= ; ;
