[A-7,M-8]) ; Id: <1.5.4.16.20140502165540.2aaf28fa@earthlink.net> ; --------- ; ; FOTD -- May 02, 2014 (Rating A-7,M-8) ; ; Fractal visionaries and enthusiasts: ; ; The name of today's image asks a question -- "How Low Are We?" ; The real(p1) parameter answers that question. The exponent of Z ; in today's image lies at the lowly level of 1.067, a level where ; fractals would normally be assumed to be virtually impossible, ; much less filled with minibrots. But thanks to the overworked ; MandelbrotBC3, which calculates the multiple values of the ; complex-log function, we have not only a fractal, but a rather ; exciting minibrot. ; ; The parent fractal resembles an orca swimming freely through its ; natural habitat, the ocean. The fractal orca is surrounded by a ; cloud of sandy debris that could be bubbles. Today's scene is ; located in this bubble debris, to the lower left of the orca. ; ; The minibrot in today's image is shaped like a plunging rocket ; ship, not at all like the orca shape of its parent. Almost all ; minibrots in this ultra-low range of exponents of Z are shaped ; like rockets or torpedoes, but this does not mean the scenes are ; worthless. The features surrounding the minibrots can sometimes ; be surprising. ; ; The art worth of today's image rates a 7. In my opinion, the ; art aspect is notably above average, held up by its brilliant ; coloring. The math rating of an 8 points to the surprise of ; finding a minibrot in a fractal with an exponent of Z as low as ; 1.067. And this is not the lowest possible exponent that would ; produce a fractal with minibrots. Like all things fractal, ; there is no well-defined cut-off point below which fractals with ; minibrots are impossible. Finding them simply becomes ever more ; difficult until the fractalist simply stops his search. ; ; The maxiter of today's image is 420,000, which results in a ; calculation time of 7-1/2 minutes. This is a good example of ; the increasing difficulty as the exponent approaches unity. And ; even with this extreme value, the minibrot is far from fully ; resolved. Luckily, the web sites are there to bring relief. ; ; So escape fractal drudgery. Check the finished image at: ; ; ; ; ; ; ; ; ; ; Today brought a mix of clouds and sun, brisk winds and a ; temperature of 61F 16C to Fractal Central. The fractal cats, ; now quite difficult to tell apart from a distance, had a playful ; day. The humans had a work day. The next FOTD will be delayed ; until May 4, two days from now. Until then, take care, and I ; just found a mind hiding under the stairs. Did anyone lose ; theirs? ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= How_Low_Are_We? { ; time=0:07:30.00 SF5 at 2000MHZ reset=2004 type=formula formulafile=basicer.frm formulaname=MandelbrotBC3 function=ident passes=t center-mag=-7.525986636549002/-3.471416076886733/\ 3.47627e+010/1/110/0 params=1.067/0/0/1500 float=y maxiter=420000 inside=0 logmap=395 colors=000d00b00`00_00Y00U02R0GT1JU5LW7MYCO_ER`JTb\ MUdRWdUY_TWUTWPTWLTWGTWCTW7TW4TW7URCUMGWJLWEOWCTY7\ YY5b_1f_0l_0q`0w`0z`0sb0nd0gd2`f7WgDRgHLiHGlHClH6n\ H2oH0oHAnHOlHbiHsiHq`HqTHqMEqEDo76o20o00o00zRDzziq\ zY_zOJzD5z50y00w00s00o00l00g20d60`A0YD0UH0RM0OP0PM\ 1RJ5TGAUEGWCLY9R_6W`5giMusfln_dgTYbMRYGLTALMDLHEGD\ GA9H55J01L50MA0OF0LK0HP2EV5C`79bA6fD4iH2nP0qY0sd0w\ d0zo0zuczyzzzz2PH5PH7PH9PHCPHDPHGPHHPHLPHOcYPcYTcY\ UcYYcY_cYbcYdcYbcobcobco`co`co`co_co_co_ozYozYozYo\ zWozWozWozGtz4tz0tzctzctzctzctzctzctzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzz } 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|
