I have ; no idea how to rate it. To begin, it's neither a Mandelbrot ; image nor a Julia image. It's an Oblate image, which means the ; orientation of the slice is determined by the real(Z) axis and ; imag(C) axis. ; ; The scene is located in Seahorse Valley of the large minibrot on ; the main spike of the Mandelbrot set. But the actual location ; is but a small part of the image. I lost track of the amount of ; rotation, stretching and skewing that went into it. ; ; The image shows just two of the bottomless pits and endless ; spirals that fill the area. All the tiny nodes scattered ; through the frame are more bottomless pits, and those pits are ; filled with even tinier pits, to infinity. That's how it goes ; with fractals. ; ; The name "Galactic Collision" came to mind at an early stage of ; the coloring, when the image consisted of deep blues speckled ; with tiny dots that resembled stars, and actually did somewhat ; resemble colliding galaxies. Since then I have totally ; re-colored the image to the fiery reds that now prevail, though ; I have the original name. (Perhaps I should have stuck with the ; original colors.) ; ; The slow calculation time of 55 minutes is largely due to the ; unusually high maxiter of the upper right quadrant of the scene, ; where some elements have a maxiter of over 200,000. (The ; purplish band curving around the bottomless pit in the lower ; left is actually the lowest-iteration part of the entire image.) ; ; The official FOTD web site, where the finished image is posted, ; may be accessed at: ; ; ; ; The high-definition version of the image is at: ; ; ; ; The original classic web site may be found at: ; ; ; ; Heavy clouds ruled the sky here at Fractal Central today, with a ; steady rain in the afternoon adding to the unpleasantness. The ; temperature of 73F 23C was fair enough. It's too bad the ; weather was not fair also. The fractal cats, who lead boring ; but notably longer lives as indoor cats, took no notice at all ; of the weather. Food and play was at the top of their agenda. ; ; Finishing the week's work was at the top of the human agenda, ; and this task was accomplished with only minor problems. The ; next FOTD will be posted in 24 hours. Until that blissful ; moment arrives, take care, and it's all the fault of those ; aliens from the Herculean cluster, who are using earth as their ; experimental laboratory. ; ; No, I do not actually believe that aliens from outer space are ; running the affairs of we humans here on earth. But I would ; have no trouble writing a book about an alien conspiracy and ; using the things we have done and are doing to ourselves as ; 'proof' that aliens are among us . . . hey, maybe I'll do it. ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= Galactic_Collision { ; time=0:55:41.26-SF5 on P4-2000 reset=2004 type=formula formulafile=basicer.frm formulaname=SliceJulibrot2 passes=1 periodicity=6 center-mag=-0.02877222954091648/+0.000204047718176\ 44/6741119/0.0001957/-0.030483234210959366/-89.948\ 0538795542941 params=0/0/90/0/-1.76852919227/0/0/0 float=y maxiter=200000 inside=255 logmap=-843 colors=000cDOcCNcCMcCMcCLcCKcBKcBJcBIcBIcBHcAHbAGb\ AFbAFbAEaADa9Da9Ca9CY9B_9A`8A`89b88c88d87f86g76h75\ j75k74l73n63o62p61r61s60t60u81u92uA3uC4uD5uE6uF7vH\ 7vI8vJ9vLAvMBvNCvODwQDwREwSFwTGwVHwWIwXJxZJx_Kx`Lx\ aMxcNxdOxePygPyhQyiRyjSylTymUynVyoVwmWulXtkXriYqhY\ ogZneZld_jc_ia`g``f_adYacXbaWb`UcZTcXSdWQeUPeTOfRM\ fQLgOKgNIhLHhJGiIEiGDjFCjDAkC9kA8lA4j96k97l99m8An8\ Bo8Dp7Eq7Gr7Hs6Hu7It8It9IsAIsAIrBJrCJqDJqEJpEJpFJo\ GKoHKnIKnIKmJKmKKlLLlMLkMLkNLkOLjPMjQMiQMiRMhSMhTM\ gUNgUNfVNfWNeXNeYNdYOdZOc_Oc`ObaObaOb`Nc`Nc`Nd`Nd`\ Nd_Ne_Ne_Ne_Mf_Mf_MfZMgZMgZMgZMhZMhZLhYLiYLiYLiYLj\ YLjYLjXLkXKkXKkXKlXKlXKlWKmWKmWKmWJnWJnWJnVJoVJoVJ\ oVJpVJpUJqUKqUKrUKrUKsUKsUKtUKtUKuUKuUKvUKvUKwUKwU\ KwUPxUPxUPxUPyUPyUPyUPzUPzUPzUUzUUzUUzUUzUUzUUzUUz\ UUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUUzUU\ zUUzUUzUUzUUzUUzUUzUUzUUz } frm:SliceJulibrot2 {; draws most 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), c=p+flip(q)+p3, z=r+flip(s)+p4: z=sqr(z)+c |z|<=9 } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
