The image lies in the parent fractal that results ; when Z^(1.618) (golden ratio) is iterated Z(-3.142) (minus-PI) ; levels up the complex logarithmic hyper-spiral with the 'floor' ; function applied, and C is added. ; ; The parent fractal closely resembles a non-critical Mandelbrot ; set with its main bud pointing northeast and a nest of cut-off ; zigzagging filaments just beyond the bud. Today's scene lies ; deep in the most prominent cut-off filament. ; ; I rated the image at a 6. The colors are fair enough, but I ; have used a similar palette much too recently to allow a rating ; any higher than the 6. ; ; The name "Totally Eclipsed" came about when I imagined I saw a ; solar eclipse in the image. ; ; The calculation time of 1 minute is conveniently fast, at least ; for those with DOS-capable machines. And the finished image ; will soon be posted on the currently active FOTD web site at: ; ; ; ; The original FOTD web site at: ; ; ; ; is still available, and holds over 13 years of FOTD's. But it ; might not be up to date. ; ; Thick clouds and a temperature around 25F -4C kept things ; suppressed here at Fractal Central on Thursday. The fractal ; cats kept happy on their warm shelf, taking breaks only often ; enough to be sure things were under control outside. ; ; My day was hurried enough. The next FOTD will be posted in 24 ; hours. Until then, take care, and could something sinister be ; going on behind the scenes? ; ; ; Jim Muth ; jamth@mindspring.com ; ; ; START PARAMETER FILE======================================= Totally_Eclipsed { ; time=0:01:04.21-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=MandelbrotBC3 function=floor float=y center-mag=+1.502630890717709/+1.587875052969523/\ 1.5721e+012/1/60/0 params=1.618/0/-3.142/0 inside=0 maxiter=400 logmap=176 mathtolerance=0.05/1 colors=00010220430640850A60C70E80G90IA0KA0MA0OA1QA\ 2SA3UA4WA5YA6_A7aA8cA9eAAgABiACkCDmEEmGFmIGmJImKKm\ LMmKOmLQmMSmNUmPWmQYmR_mSamUcmVemWgmWioWlsXouXrydu\ zmzzLFUJKWQPYVP_ZR`fZbkadogetogxsinjjgklXln`loTjnQ\ inNgnKfnHenEcnBbn9anMgkZmiksgjocjl_jiXjfTjcPj`MjYI\ jVEjSBjP7jM4lL5mK6nJ7oJ8qI9rHAsGBtGCvFDwEExDFyDFoF\ DeGCWHAMJ9CK73L64N84OA4QB4RD4SF4UG4VI5XK5YL5ZN5`P5\ aQ5cS5dU5eV6fY7f`8gc9gfAgiBhlChoDhqIjnNklSmiXngaoe\ fqbkr`ptYuuWzvUswXmxZgyaazcWzfQzhKzkEzm8zp2zrLzmcz\ hvzcuzbtzaszarz`qz_pz_pzZozZnzYmzXlzXkzWkzWhzYfzZc\ z_azaZzbXzcUzeSzfPzgNzhMzgLzgKzgJzfJzeIzdIzcIzcHzb\ HzaGz`Gz_Gz_DzgBzo9zwGzLEzGCzCxzwZzYLzKKzJJzIIzHHz\ GGzFFzEFzDEzCDzBCzABz9Az8UzlSzgQzc8zD5zA3z77zABzDF\ zFJzINzKRzNVzQZzSbzVfzXjz_mzaPzuQzuQzuRzuRzuSzuSzu\ TzuTzuTzuUzuUzuVzuVzuWzuWzuWzu_zwbzyezzdzyczybzyaz\ yazyczmdzafzQgzEezDczDazC } 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|
