Don't ask what this series of formulas does; I have ; no idea. But whatever they do makes some interesting fractals. ; ; Most of the image consists of inside stuff brought to life by ; the 'bof60' inside fill, which colors the points according to ; how close they come to the origin. ; ; The name "Eruption in Progress" came about when I fancied a ; volcano on some abstract mathematical alien planet erupting ; strings of bubbles. The rating of an 8-1/2 includes the usual ; 1/2 point for the effort I put into tweaking the colors to get ; the smooth pastel effect. ; ; The calculation time of 1-1/4 minutes is quite fast, and will ; cause no one the least bit of impatience. The only ones in ; trouble could be those with new-fangled and over-qualified ; machines that have forgotten how to run old-fashioned DOS pro- ; grams. But even for these few, relief is at hand. The image ; has been already calculated and posted to the FOTD web site at: ; ; ; ; where one may view it at leisure and say 'aaaaahhh'. ; ; Heavy clouds and rain spoiled almost everything here at Fractal ; Central on Wednesday. The chilly un-springlike temperature of ; 48F 9C gave no consolation at all to the fractal cats, who gave ; up waiting for the sun early in the afternoon and spent the rest ; of the day getting into trouble in and around the book shelves ; in the F.C. hallway. ; ; My day was spent finishing up some work left over from Tuesday. ; The immediate future looks slow, but like the weather, this has ; a way of changing suddenly. The next FOTD will be posted by me ; in 24 hours. Until then, take care, and fight violently to ; bring about a world where all the ethnic, political and relig- ; ious groups live together in peace and harmony. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= EruptionInProgress { ; time=0:01:16.51-SF5 on P4-2000 reset=1960 type=formula formulafile=mandnewt.frm formulaname=MandNewt05 function=atanh passes=1 center-mag=0.490891/0.11292/0.6210325/1/-25/0 params=0.9141/3.2639/-3.3039/-1.062/-0.3534/3.0686 float=y maxiter=180 inside=bof60 logmap=yes periodicity=10 colors=000zzJzyJzwIzuIzsIzrHzqHzpHzoHznGzmGzlGzkFz\ jFziFwhFtgFqfEneEkdEhcDebDbaD_`CX_CUYCRWBOUBLTBKSA\ KRAKRAII3H00mzzmzzmzzlzzkyziyzgyyeyxcxwaxu_xsYxqWw\ oUwmTwmSwlRwlQwlPvlOvlPulQulRtlSslTslUslVrlWrlXqlY\ qlZpl_ol`nlamlbllcklejlfilghlhglifljelkdllclmblnal\ o`lp_lqZlrYlrYlrYlrYlrYlrYlrYlrXlrXkrXkqXkpXkoXjnX\ jmXjlXjkXjjXiiXihXigXifXheXhdXhcXhbXgaXf`Xh_XgZXgY\ XgXXfWXfVXfUXfTXeSXeSXeRXeQXdPXdOXdNXdMXcLXcKXcJXc\ IXcHXbGXbFXbEXbDXaCXaCXaBXaAX`9X`CX`FX`IX_LX_OX_RX\ _UW`XW`_V`bVaeWahXakYbnZbq_bt`bv_bvYdwWcwTbtTarSao\ S`mR_jRYhRVgPVdPScNUaMQ`MOZLKXKIWJFUIESGDPDDMACJ08\ YLQXLPXKPWKOWKNVKNUJMUJLTJKTIKSIJeHIdHHdGHcGGcGFbF\ FaFEaFD`ED`EC_DC_DBZDAYCAYC9XC8XB8WB7VB6UC6VC6VC6W\ B6WB6XB6XB6YB6YA6ZA6ZA6_A6_A6`96`96a96b96b96c86c86\ d86d86e86e76f76f76g76g76h66h66i66jA7kA8lA9lA9lA9lA\ 9lA9lA9mAAmAAmAAmAAmAAmAA } frm:MandNewt05 {; Jim Muth z=c=fn1(pixel): a=z^2+(c-p1)*z-c b=p2*z^2+c-1 z=z-1*a/b p3 <= |a| } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
