Before deleting them, and being certain I was off- ; line, I checked the content of one e-mail, which had an ; unusually clever subject line about an old friend who had just ; found me. Not surprisingly, the letter was not from an old ; friend, but from one of those questionable on-line pharmacies ; with doctors who prescribe prescription drugs without an examina- ; tion. It would have been just another unwanted piece of junk ; had it not been for the line that read, "if you act now, your ; order can be shipped by January". No wonder only one recipient ; in ten-thousand replies to such letters. ; ; Fractals are far more reasonable. Today's image has been ; created by an entirely different formula than yesterday's, but ; the same brush-like shape is there. Whereas I decided that ; yesterday's image rated a 6 and then lowered it to a 5 at the ; last minute, today's image rates a firm 7. I named the image ; "More of the Brush" in recognition of the fact that its basic ; shape closely resemble the brush shape of yesterday's image. ; ; The formula behind today's image is Z^10-Z^9+C. This formula ; produces a parent fractal that is little more than an circle ; with broken bays around its perimeter. It displays critical ; characteristics only in the area of its 'East Valley', which is ; where today's scene is located. ; ; The outside parts of today's image were rendered by the 'fmod' ; option, which in this case does a better job than the standard ; equal-iteration-bands method. The brilliant turquoise color of ; the inside of the central midget is a departure from my standard ; dead black inside color, used today because it works well. ; ; The 5-minute render time is within reason, but the 1-minute-or- ; less download time is even more reasonable. The GIF image can ; be found, ready for download at either one of the two FOTD web ; sites: ; ; ; ; and: ; ; ; ; The clouds hung around most of Sunday at Fractal Central while ; we were away on the shopping trip. When we returned at 6pm, the ; sun was trying to break through, the temperature was 79F 26C, ; and the cats were ready to romp. They enjoyed the yard for over ; two hours before hunger brought them inside to eat. Today is ; sunny and warmer -- the kind of weather fractal cats approve of. ; ; I've got a bit of work to do before I re-enter the world of ; fractals, and the sooner I get started, the sooner I'll finish. ; So until next FOTD, take care, and don't lose the faith. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE================================ More_of_the_Brush { ; time=0:05:24.29--SF5 on a P200 reset=2002 type=formula formulafile=allinone.frm formulaname=MandelbrotMix2 function=ident passes=1 center-mag=+1.00172680834191900/-0.000089662866518\ 10/8255452/1/-147.5/1.85261191e-007 params=1/10/-1\ /9/0/0/0/0 float=y maxiter=850 inside=255 proximity=0.7 outside=fmod logmap=yes periodicity=10 colors=000zzwyztxzqwznuzkszhqzhozhmzhkzhizhgzieyic\ xiawi_viZuiYtiXsiWrjVqiUpiTohSnhRmgQlgPkgOjfNifMhe\ LgeKfeKedKddJccJbcJabJ`bI_bIZaIYaIX`HW`HV`HU_HS_GR\ ZGQZGOYFNYFMYFKXFJXEIWEGWEFWEEVDCVDBUDAUD9UE8VF8WG\ 8WG8XH8YI8YI8ZJ8ZK8_K8`L8`M8aM8aN8bO8cO8cP8dQ8dR8e\ R8fS8fT8gT8hU8hV8iV8iW8jX7kX7kY7lZ7lZ7m_7n`7n`7oa7\ ob7pc7qc7qd7re7se7sf7tg7tg7uh7vi7vi7wj7xk7yk7zl7zm\ 7zm7zl9zlAzlCzkDzkEzkFzjGzjHzjIziJziKziLzhMzhNzhOz\ gPzgQzgRzgSzfTzfUzfVzeWzeXzeYzdZzd_zd`zcazcbzcczbd\ zbezbfzbgzahzaizajz`kz`lz`mz_nz_oz_pzZqzZrzZszYtzY\ uyYvxYwwXxvXxuXwtWvsWurWtqVspVroVqnUpmUolUnkTmjTli\ TkhSjgSifSheSgdRfcRebRdaQc`Qb_QaZP`YP_YPZXOYWOXVOW\ UNVTNUSNTRMSQMRPMQOMPNLOMLNLLMKKLJKKIKJHJJGJIFJHEI\ GDIFCIEBHDAHC9HB8HB8HFBHJDHMFHQHHUJHXLH`NHdQHgSHkU\ HoWHrYHv_Gz`HyaHxaIwaIvbJubJubKtcKscKrcLqcLpdMpdNg\ fNhfNhfNifNigNjgNjgNkg0zz } frm:MandelbrotMix2 {; 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)+(p4)), 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================================== ;
