This ; parent resembles the familiar ground level PI fractal rotated ; about 30 degrees so that the north bud faces northeast. Today's ; image is located in the debris surrounding a small distorted bud ; on the fractured western shore line of the southern lobe of the ; main bay, just north of the negative X-axis. ; ; I usually avoid spirals in my fractals, since currently trendy ; fractals are over-populated with them, but today's fractal is so ; unusual that I just had to show it. Instead of consisting of ; continuous unbroken arms, the spiral surrounding the minibrot in ; today's image consists of isolated patches of debris spotted in ; a spiral pattern. This plus the coloring raises the rating to a ; respectable 7-1/2. ; ; The name "PI Celebration" needs no explanation. The calculation ; time of 1-1/4 minutes leaves only a tiny opening for impatience ; and boredom to creep in. And even this tiny possibility may be ; eliminated by visiting the web sites. ; ; The image is posted already calculated on the FOTD web site at: ; ; ; ; A high-definition rendering is posted at: ; ; ; ; The back images are online at: ; ; ; ; The day began with a bank of river fog obscuring the sky, but by ; mid-morning the fog cleared off, revealing a higher layer of ; clouds that prevailed for the rest of the day. The temperature ; of 73F 23C and lack of hot sun kept it quite comfortable for the ; middle of August. ; ; The house watch cats, Cassie and Nicholas, being indoor cats, ; had little to say about the outside conditions. The humans, ; being at least marginally human, had other things, such as ; discussing politics, to occupy their time. ; ; The next in the unending series of FOTD fractals will soon be ; posted. Until whenever, take care, and is the FOTD finally ; running out of steam after 15 years? Stay tuned for the next 15 ; years to find out. ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= PI_Celebration { ; time=0:01:15.00 SF5 at 2000MHZ reset=2004 type=formula formulafile=basicer.frm formulaname=MandelbrotBC3 function=ceil center-mag=-0.6252176739160485/+0.0538719225787179\ /3.284e+009/1/147.5/0 params=3.14159265358979/0/\ 3.14159265358979/0 float=y maxiter=2000 inside=0 logmap=142 periodicity=6 colors=000Kx0Kw0Kv0Ku0Kt0Ks0Kr0Kq0Kp0Ko3Kn4Km4Ii5G\ f5Eb6C_6AW78T76P84M82I90F91E81D81B71A7186176266245\ 23530420420480AEJGKOMQSSWXYa`cgeimiopnzrzzrwwqmzpk\ lrihpfcod_mbVl`RkZNc`LWbJOdHGfFFhDKbKPYQUTWZOacIhh\ Dnn8tq3zo4xm4wk5vi5ug6te6sc7ra7q_ApYFoWKnUPnQUnMZz\ KczIhzGmzErzCwzHrzMmzQhzVdzZbzc`zhZulXvqVwuUxnYyha\ ybezXizVgxUewTcvRauQ_tPYsNWrMUqLTpMVnNWlOXjPZiQ_gR\ `eRbdScbTd`Uf_VgYWhWWiVXhTYgSZfR_fQ`ePadNbdMccLdbK\ ebJb`N`_RZZUXYYVX`TWdRVgNSTPOVRKWTHXRIWPIVNIULJTJJ\ SIJSGJREKQCKPAKO9KOBJNCIMEHMFGLHFKIEKKDJLCINBIOAHQ\ 9GR8GT7FU6EV6EU8GT9ISBKSCMREOQFQQHSPUUOUWcUYcU_cUa\ cUchUehTgmUhmRdmU`mUXmUUrUQrUMvUJzUFzUBzU8zU8zU8zU\ 8zc8zc8zc8zc8zc8zc8zh8zm8zr9zvAzzBzzCzzCzzDzzEzzFz\ zGzzGzzHzzIzzJzzKzzKzzUzzbzzlDzzFzzHzzJzzKzzMzzOzz\ QzzRzzTzzVzzXzzYzzXzzWzzVzzUzbTzcSzdRzeQzePzfOzgNz\ hNzhMzgLzfLzfKzeJzeJzdIzd } 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|
