The ; image, which shows the entire parent fractal, was created by the ; JimsCompMand formula. This formula can increase the number of ; arms in Mandel-type fractals, and it can also reduce the number ; of arms, as it has done in today's image, where the Z^(-1000) ; Mandeloid has had its arms reduced from 1001 to merely 3. ; ; This reduction in the number of arms brings out the delicate ; intricacy of the high-order fractals with negative exponents and ; large escape radii. The natural delicate effect was enhanced in ; today's image by the softly-glowing background, which was ; created with the 'bof60' inside fill and a bit of applied color ; theory. The black-to-orange shading of the foreground elements ; was achieved by setting the outside to 'fmod' and the proximity ; to a very high 1650. ; ; The effect of delicacy can be made stronger by increasing the ; escape radius beyond the 1100 that was used in the image. When ; this is done, the foreground elements gradually grow smaller. I ; assume they would eventually disappear entirely, though I have ; not taken the escape radius this far. Changing the inside and ; outside fills also creates interesting effects. The 'bof61' and ; 'atan' inside fills are particularly effective, as are several ; of the other outside options. ; ; I named the image "Mysterious Triangle", though there is really ; nothing very mysterious about it -- except that it is a fractal ; -- and we know how mysterious they are. ; ; The rating of a cosmic 9 and the brief render time of 1-1/2 ; minutes combine to create an image with an overall worth of 577. ; This is not the highest overall worth of all time, but those ; higher worths are somewhat artificial, having been achieved by ; render times of only a few seconds. ; ; As always, the finished image is available on the FOTD web site ; at: ; ; ; ; Heavy snow fell all afternoon Saturday here at Fractal Central, ; piling up to a depth of 6in 15cm. The temperature reached a ; high of only 16F -9C. The fractal cats took one brief smell of ; the outside air and decided that their adventure would be more ; comfortable on the window shelf. A treat of extra tuna in the ; evening insured their contentment. Today is starting cloudy. ; The snow has ended, but the temperature is 12F -11C, and the ; high winds are blowing the snow into drifts. The duo have ; already accepted that it will be another inside day. ; ; For me, the task is to clear the driveway and sidewalk, but ; before tackling that job I will wait for the drifting snow to ; settle down. The delay will give me a chance to find another ; fractal hopefully as good as today's. The next FOTD will appear ; in 24 hours. The vaguely fractal philosophy might or might not ; be included. Until then, take care, and see the light. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= MysteriousTriangle { ; time=0:01:33.60--SF5 on a P200 reset=2004 type=formula formulafile=allinone.frm formulaname=JimsCompMand passes=1 center-mag=1.64342/2.84649/0.08912656/1/30/-1.233\ 73533611470521e-014 params=-1000/0/999/0/1000/0 float=y maxiter=2500 inside=bof60 proximity=1650 outside=fmod logmap=yes periodicity=10 colors=0000AHAAHLAHTAHXAHaAHeAHhAHjAHlAHkAHoAIqDJs\ HKuKLpOMpRNpVOpYPp`PpcQpfRpjSpmTqqUrtVswWuyXwzXxzW\ yyVzsUzwUzvTzuSztSwsRtqQqqQnpPknOhmOhlNgjMfiMfgLef\ KeeK`iRWlXRocMsiHvpCyvEvqFtmGrhHodJm_KkWLhSMfNOdJP\ aEQ_ARY6QZBQZGQZLP_QP_VP__u6Ks5Jr5Iq5Hp5Hn5Gm5Fl5F\ k5Ei5Dh5Dg5Cf5Bd5Bc5Ab49a48_48Z47Y46X46V45U44T44S4\ 3Q42P42O41N40M40N54O67O7BP8EQ9HQALRBORBRVFPZJObNMf\ RLjVJnZIlXHkWHjUHiTHhRHgQHfOHeNGdLGcKGbJGaHG`GG_EG\ ZDFYBFXAFW8FV7FU5FT4FS3GU5IV7JW9KXBMYDNZFP_HR`JSaL\ TbNVcPWdRXeTZfV_gX`hZbi`djbfkdilfkmgmngoohpohrpitq\ iurjvrjwskwtkxtlyulyvlzvlzulytlxskwrkwqjvqjupitoit\ nhsmhrlgrlgqkfpjfoieohengdmgdmfcleckdbjcbjbaibaha`\ h``g__fZ_eYZeYZdXYcWYcVXbUXaTW`TW`SV_RVZQUYPTYOSXO\ RWNQWMPVLOUKNTJMSJLRIKQHJPGIOFHNEGMEFLDEKCDJBCIABH\ 9AG99F88E77D66C55B44A439328017206105004zR1yQ0xQ0wP\ 0vP0uP0tO0sO0rN0qN0pN0oM0 } frm:JimsCompMand {; Jim Muth z=c=pixel: z=z^p1*(c^(p2-1))+c, |z| <= p3+100 } ; END PARAMETER FILE========================================= ; ;
