The parent fractal of ; today's image results. ; ; More than anything else, this parent resembles a Mandelbrot set ; that has been killed and flattened on the road. I will not try ; to describe the resulting mess, which bears only a vague simi- ; larity to the un-flattened M-set. But I will comment that it ; has a large 2-lobed bay filled with only the tiniest bits and ; pieces of 'outside' stuff. Today's scene is located in one of ; the denser fields of this stuff. ; ; The effect of broad radiating bands was achieved by rendering ; the image with the 'inside' set to 'bof61'. The only 'outside' ; elements in the image are the four large warm-red ones surround- ; ing the invisible-but-really-there minibrot at the center, as ; well as the scattered bits of salt and pepper. ; ; The first name I chose for the image was 'Road-Kill Fractal". ; But this name brings up too many unpleasant images, so I finally ; chose the name "A Virtual Vacuum". Since so much of the image, ; which is not evaporated, consists of 'inside' stuff, the image ; actually is rather empty, though perhaps not quite a true vacuum. ; ; I kind of like the intense contrasts in the image. The rating ; of an 8.5 must therefore be considered totally justified. The ; calculation time of 49 seconds is thankfully brief. Equally ; convenient is a trip to the FOTD web site at: ; ; ; ; to view the image there. ; ; Midsummer weather in mid-October is hardly to be expected, but ; when the temperature reached 91F 33C on Monday here at Fractal ; Central, along with haze and high humidity, one might have sworn ; it was mid-July. The fractal cats never noticed the hot weather ; as they hogged the cool air during the hottest part of the day. ; ; I was too busy to complain about the afternoon heat, but when ; evening came and the work was finished, I started to grumble. ; Luckily, the unusually spectacular fractal of the day eased my ; dis-satisfaction. The next FOTD image will be ready, along with ; its brief discussion, in about 24 hours. Until then, take care, ; and when a question cannot possibly be answered, the question is ; sometimes a meaningless one. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= A_Virtual_Vacuum { ; time=0:00:49.62-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=MandAutoCritInZ function=ident passes=1 center-mag=+2.37151777147614800/-0.506331567794958\ 40/1.611897e+007/1/32.5/-5.04488026451949123e-005 params=0.2/2/-2/-0.5/0/0/0/0 float=y maxiter=2500 inside=bof61 periodicity=10 mathtolerance=0.05/1 colors=0005Kc5JdCNfIQhOTjUWl`Znfapldrrgt`XhKMX3CI9\ HJEMHKREPVCV_9_d7dh5`b8XXBTRDPLGLFIH9LE4N3CwijYalc\ VnhNozGqs9rxCnpEjhHfaJbUMZMOVFRR7TO0WL7ZID`FJcCQh9\ Wm6Zr4Uv6PzRKvOKrKKmHKhFKcEKZCKUCKPCLRVMWeMgpMlxMr\ zNexL_wJVvHPuFJtDEsBDUUQLXbB_n2ahQLcl4Vh8NdBF`E7YH\ KSDXMAiG6uA3rF6oK8lOAjTDgXFdaHbeJXdPRcULbZGbcL_gQX\ jVUm_RpUNlPJhJFdEB`GGdIKhKOkJUmI_oHepGkrGqsIZ_KHGI\ JEGLCENACP8AR68T46V24W1TKVq9xoFpmLikQaiWVgaOefGcl9\ aq2XjBScKOXSJQ`FJhipD8le1rmRuroxw4ZG5`J6bL6dO7fQ8h\ T9jWAlYBn`BpbAoeAogAoiAok9nn9np9nrTbcSacR_cQZdPYdO\ WdNVeLSeKRfJQfIPfHOgGNgFMgEKhDJhCIh9PY7WO4bE2i41WL\ GTQVQVhN_iOZiPYiQXjRXjSWjTVkUUVdIWiJXnKYsKheQsTWgd\ jceb`fWYgPUhIRiBOj4Ed34Z3Cc5Jh6Rm8Yr9dwAfuKhtUisck\ rmlqwhrrdsn`tjXufTvbPwZOo`NgaM_cMSdUWWaZOibFpe7lb6\ h_5dX5`U4YS4lGNz4emCYaJQQRIEYA2d3Cf4Lg5Ui6cj7ll8um\ 8vhAvdCv_EwWGwRIwNKwJM5Lb } frm:MandAutoCritInZ {; Jim Muth a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=1/f, h=1/d, j=1/(f-b), z=(((-a*b*g*h)^j)+(p4)), k=real(p3)+1, l=imag(p3)+100, c=fn1(pixel): z=k*((a*(z^b))+(d*(z^f)))+c, |z| < l } ; END PARAMETER FILE========================================= ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
