At the same ; time it will set no new records for a fractal rating. ; ; The image is the center part of its parent fractal, which is a ; Julia set of the Mandeloid that results when Z^2 is divided by ; ((Z^6)+0.6). The Mandeloid is still dominated by Z^8 elements, ; though even with only 0.6 added, the western bay is already ; growing larger. Today's Julia image corresponds to the northern ; branch of the valley setting off this enlarging bay. ; ; A quick glance will reveal that the image is far too busy, with ; too many clashing colors vying for attention. It really doesn't ; deserve even the lowly rating of a 5.5 that I gave it. ; ; The strange imag(p3) parameter was found at random by the ; evolver feature of Fractint. The value is extremely critical. ; ; The name "Julia to the Center" indicates that the image is the ; center of a Julia set. ; ; The calculation time of 1-1/2 minutes will get the task of ; running the parameter file out of the way in a hurry. The joy ; of visiting the FOTD web site at: ; ; ; ; and viewing the finished image posted there can hardly be ; surpassed. ;-) ; ; The perfect weather fled fast on Tuesday here at Fractal ; Central, where grey skies and sprinkles of rain made no one ; happy. It was also very humid, making the temperature of 84F ; 29C feel quite oppressive. The fractal cats spent most of the ; day contemplating fractals, while I spent most of the day ; contemplating and then actually doing work. ; ; The next FOTD will appear from nowhere almost by magic in 24 ; hours. Until then, take care, and watch for the relief. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Julia_To_TheCenter { ; time=0:01:31.58-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=DivideJulibrot passes=1 center-mag=0/0/4.464286/1/32.5/0 periodicity=0 params=90/90/90/90/-0.8682316/0.06717689238662033/\ 0/0/8/0.6 float=y maxiter=750 inside=255 logmap=-24 colors=00000X00Y00Z00_00`00a00b00c00d00e00f00g00h0\ 0h00g00e00c00b00a00`00_00Z00Yd9zf9zgBziCzkEzlEznGz\ pHzqJzsJztKzvMzxOzyMzxOzvPztPxsRvqRtpTqnTplVnkWkiW\ igYgfYdd_cc_ac`Za`X`bVZdSXdQVePUeLSgKQgGPhFNhDLjAK\ k8Ik6Im3Gm1Fo0Do0Bp0Ap08r06t04t03u01u00w00w00y00y0\ 0w00w01w03u03u04u06u08t0At0At0Br0Dr0Fr0Gr0Gp0Ip0Kp\ 0Lp0Lo0No0Po0Qm0Sm0Sm0Um0Vk0Xk0Zk0Zj0`j0aj0cj0ch0d\ h0fh0gh0ig0ig0kg0le1ne1pe1pe3qd3sd4td4sg3td4tb6v`8\ wYAuWBsVDqRFpPGoOGnKImJKmHLmGNmCPmBQm9Sm6Um4Um2Um0\ Um0Um0Uz0Um0Uz0Um0Uz0Um0Uz0Um0Uz0Um0Um0Uz0Um0Uz0Um\ 0Uz0Um0Ux0Um0Uv0Um0Uzt0s_Daz0`t0zk0Xe0XY0VP0UJ0t4N\ s7QzVNpGXnJ`lMckzfiVigYlf`pddqZ_iSVaLPUFKL8GD1C6F9\ GQ6Qc2`n0iz0sz0zz0vz0sy0pt0lq0il0fg0cd0``0XX0US0QN\ 0NK0KF0GtRD60A106003000000001404B48IBBQHGXOKcVNi`Q\ pgUlbUiYUgVUdPUaKU`HUXCUV9US4UP0UN0UK0UI0UF0UB0UA0\ U60U40UB0XI0`N0aU0dZ0gd0i } frm:DivideJulibrot {; draws 4-D slices of DivideBrot Julibrots 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), aa=real(p5)-2, bb=imag(p5)+0.00000000000000000001, 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)/(z^(-aa)+bb)+c |z|< 1000000 } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
