The mathematical interest is just ; about all it has going for it. The image itself is little more ; than a passing scene in an infinite world of fractals. And the ; calculation time of nearly 2 hours is far beyond reason. In ; addition, the exponent of Z that created the image is 1.0005, so ; close to unity that no one in his right mind would enter it as a ; parameter with any expectation at all of finding much more than ; smooth and straight band edges. ; ; Questioning my own sanity, I did enter this value as the ; exponent of Z, and in addition I felt fairly confident of ; finding something of interest. Today's image is what popped up ; where nothing should exist. ; ; The scene is neither a Julia set nor a Mandelbrot set, but ; something in between. The detail in the image is not the ; organized chaos that makes most fractals so interesting. The ; detail in today's image consists of countless discontinuities ; arranged into half-orderly elements. If any part of the image ; is zoomed into, a flat featureless area will ultimately be ; arrived at. In ordinary fractal chaos, the chaotic features ; continue without limit. ; ; The name "Down in the Boondocks" refers to the exponent of Z, ; which is by far the closest to unity of any FOTD fractal so far. ; ; A price must be paid for seeing detail in a fractal so close to ; unity however. The price is the need of a very high maxiter, ; resulting in a calculation time of 1-3/4 hours, which is tedious ; indeed for such an unartistic image. But help has arrived in ; the form of the FOTD web sites. ; ; All the tedious calculating may be avoided by viewing the ; finished image on the FOTD web site at: ; ; ; ; It may be seen in high definition at: ; ; ; ; The original, now classic web site may be accessed at: ; ; ; ; The day began with clouds here at Fractal Central, but the ; clouds cleared off before noon, leading to an afternoon of ; sunshine, balmy south breezes and a temperature of 70F 21C. ; With rain and colder weather forecast, today might have been the ; last near-perfect day of the fall. ; ; The fractal cats passed a good part of the day sharing the new ; chair. The humans disagreed a bit about politics (as is ; standard) but the day passed uneventfully. The next FOTD will ; be posted in 24 hours. Until then, take care, and liberal ; thinkers know that conservative policies are the cause of the ; problems, while conservative thinkers know that liberal policies ; are the cause of the problems. Neither side appears able to ; recognize that their conflicting views of the solution are also ; a part of the problem. ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= DownInTheBoondocks { ; time=2:05:44.73-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=SliceJulibrot5 passes=1 maxiter=120000 center-mag=+2.723099067722828/+0.02123607283229285\ /6919/1/5/0 params=37.5/0/37.5/0/1.1513/0/0/0/1.00\ 05/0 float=y inside=0 logmap=-15900 periodicity=9 colors=000zdCzeEzfGzgIzhKziMzjOzkQzmSznUzoWzpYzq_z\ razsbzs_zsXysUwsRurOsqOqpOooNmnNkmNilMgkMfjMeiLdhL\ cgLbfKaeK`dK_cJZbJYaJX`IWZIVXIUVHTTHSRHROGQLGPIHOF\ GNDKMDKLFKKIKJKKINKHPKUKzTKzTKzTKzTKzTKzTKzTKzSKzS\ KzSKzSKzSKzSKzSKzRKzRKzRKzRKzRKzRKzRKzRKzQKzQKzQKz\ QKzQKzQKzQKzPKzPKzPKzPKzPKzPKzPKzOKzOKzOKzOKzOAzOA\ zOAzOAzPAzQAzRAzSAzSAzTAzUAzVAzWAzWAzXAzYAzZ1z_1z_\ 2z`2za3zb3zc4zc4zd4ze5zf5zg6zg6zh7zi7zj7zk8Wk8Yl9_\ m8an6co4eq2gr0is0ku0mv0ox0qz0sy0ux0ww0ww0ww0ww0ww0\ ww0ww0ww0ww0ww0uw0sw0qw0ow0mw0kw0iw1gw1ew2ew2ew3ew\ 4fw4gw5gw5hw6hw6iw7iw7jw8kw8kw9lwAluAmsBmqBnoComCo\ mDpmDpmEqmEqmFrmEsmFrmFqmFpmGomGomGnmHmmHlmHlmIkmI\ jmIimJimJhmJgmKfmKfmKemLdmLcmMczOazQ`zS_zUZzWXzYWz\ _VzaUzcTzeRzgQziPzkOzmMznLzpKzpJzpIzpGzpFzpEzpDzpB\ zpAzp9zp8zp7zp5zp4zp3zp2zp1zp2zp2zpfzpezpezpdzpczp\ czpbzpazpazp`zp`zp_zpZzpZ } frm:SliceJulibrot5 {; draws all slices of Julibrot pix=pixel, u=real(pix), v=imag(pix), a=pi*real(p1*0.0055555555555556), b=pi*imag(p1*0.0055555555555556), g=pi*real(p2*0.0055555555555556), d=pi*imag(p2*0.0055555555555556), ca=cos(a), cb=cos(b), sb=sin(b), cg=cos(g), sg=sin(g), cd=cos(d), sd=sin(d), p=u*cg*cd-v*(ca*sb*sg*cd+ca*cb*sd), q=u*cg*sd+v*(ca*cb*cd-ca*sb*sg*sd), r=u*sg+v*ca*sb*cg, s=v*sin(a), esc=imag(p5)+9 c=p+flip(q)+p3, z=r+flip(s)+p4: z=(-z)^(real(p5))+c |z|< esc } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
