Today's image is located on a filament extending from ; a larger minibrot in this area. ; ; I rated the image at a 6-1/2, with the extra half-point added by ; my modest coloring efforts. The name "Filament Abundance" gives ; away the appearance of the image even before it is calculated. ; ; The calculation time of 8-1/4 minutes borders on slowness. To ; avoid all chance of impatience, I recommend surfing out to the ; FOTD web site at: ; ; ; ; and viewing the already-calculated image there. ; ; Near full sun and a temperature of 37F 3C kept the fractal cats ; on their best behavior here at Fractal Central on Saturday. I ; am almost always on my best behavior, so nothing more need be ; said. The next FOTD will in all likelihood be posted in 24 ; hours. Until then, take care, and keep taking care until there ; is no more care to be taken. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Filament_Abundance { ; time=0:08:15.24-SF5 on P4-2000 reset=2004 type=formula formulafile=basic.frm formulaname=MandelbrotBC3 function=ident passes=1 center-mag=+0.778594649890781/+0.04565415904501465\ /3.0825e+009/1/-27.5/0 params=1.5/0/22.15/0 float=y maxiter=6000 inside=0 logmap=825 periodicity=10 colors=000KKcKKcKKcKKcKKcKKcKKcKKcKLcKMbKNbKObKPbL\ QbMRbRKhTKhVKhXKhVKhUKhWKhYKjZHlXKjWPgUPeSPcRPaPPf\ NJjLRnKQrJPwIOvHNuHMuGKtFItFHtEGtDJtDMtCPtBStBVtAY\ t9`t9ct8ft7it5rx7lt8gp9alAXiCSeDMaEHYEDXFCWFCVFCUG\ CTGCSGBRHBQHBPHBOIBMIAKIAIJAEJAAJAAL9AJAAIAAGBAFBA\ DCACCABCA9DA8DA6EA5EA3FA2FA0DA1FA2GA3HA4IA5JA6KB7L\ C8MD9NEAOFAPGESFIVFMXFQ_FUbFYdFahFemFirFmvFzzFzzFz\ zGzvFztFzrFzpFznFzkFziFzgFzeFvcFr`FmZFhXFfVFeTFpfo\ menjemgeledlbdk_djXcjVciSchPbhMbgKbfHafEaeBad5ig9a\ dCVbFN_JHWIGYIG_IG`HGbHFcHFeGFfGFhGEjFEkFEmFEnEDpE\ DqEDsF9sEDtEGuDLvDOwDRxCWyCZzBczBfzBjzAnzArzAuzZkf\ zgSzcTz`UvXVrUWmPThRWcSYZT`UUbQVeRWgTXiVYlXZnZ_q``\ sbcxaaza_z`Yz`Wz_Uz_SzZQzcSzaPzcNzeLzgIziGzkGNmEOo\ DOqCPsAPu9zw8zz6zz5zzczzczzczzczzzzzczzczzVJzzJzUK\ zUKzUzzUKzzLzULzUzzTMzzLzRLzQLzzLzOKzNzzMKzzKzKJzJ\ zzzJzHJzFzzLLzzMzXOzaPzzR } 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|
