When the image is run directly from ; the parameter file, the imag(p3) parameter comes up as some ; ridiculous negative number, resulting in a blank screen. To see ; the correct image, the imag(p3) parameter must be re-entered by ; hand to the correct value of 3900000000 or 3.9e+009. When this ; is done, the image generates normally. I have no idea what the ; bug is. ; ; And my apologies for the late FOTD. Fractal lady and I decided ; to take the day off on Saturday to enjoy the countryside. We ; did so much enjoying that it was almost 11pm when we made it ; back exhausted to Fractal Central. ; ; For today's fractal we return to the MandAutoCritInZ formula, ; and check the fractal that results when various parts of ; Z^(-1.1) and Z^(-7.7) are mixed before (1/C) is added. The ; resulting parent fractal is a grossly oversized thing with a ; prominent 'fan' on the X-axis, with the handle facing west. ; Today's image is located in a bit of fractal decoration on the ; blade of this fan. ; ; The bailout in today's image is almost 4-thousand-million. I ; was working with different parameters when I noticed that the ; fan evaporates as the bailout is raised. This evaporation ; starts at the handle and proceeds toward the edge. I set ; today's bailout to the point where the area of today's image is ; just about ready to evaporate, and rendered the fractal with the ; inside set to 'bof61'. The resulting image is a cross between a ; conventional image and an evaporated one. ; ; I named the image "Not a Blank Screen" for the obvious reason. ; If you see a blank screen, you have not changed the imag(p3) ; parameter. Then I rated it at a 7, which is the minimum rating ; that I consider satisfactory. In comparison to yesterday's ; image, which takes nearly an eternity to finish, today's ; finishes in under one minute on the fast P2000 machine and about ; 5 minutes on the P200. ; ; The image is also available for viewing on the FOTD web site at: ; ; ; ; but because of the unusual time of day, and the bug in the ; parameter file, it may be a few hours before it is posted there. ; So be patient. ; ; It was a bit too warm and muggy for perfection here at Fractal ; Central on Saturday, but the fractal cats didn't mind. When we ; returned late in the evening, we found Nicholas sleeping in the ; magazine rack and Cassie curled on the coffee table, both of ; them happy but hungry. ; ; Tomorrow's FOTD will be another good one, and it will appear in ; only 12 hours. Until then, take care, and save energy; shower ; with a fractal. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= Not_a_Blank_Screen { ; time=0:00:55.12-SF5 on P4-2000 reset=2004 type=formula formulafile=allinone.frm formulaname=MandAutoCritInZ function=recip passes=1 center-mag=+3.45380026680085500/-2.720203553966759\ 00/103939.7/1/-42.5/1.78789296749470861e-007 params=-4/-1.1/-0.7/-7.7/0/3900000000/0/0 float=y maxiter=1300 inside=bof61 periodicity=10 colors=000gR0Z00i02s0Tz0sz0zz0zz0zz0zz0zz0zz0zz0zz\ 0zz4zzCzzLzzTzz`zzizzqzzxxzzvzzuzzszzqxzoqzmizkbzi\ VzgNzeGzdAzdGseJmePegT`gXTibNieGkiAko2ms0mv0mz0kz0\ iz0iz0bk0VXCNHNG4Z82Z00Z0Hd02VX2N`2Hd0Ai02m00s00v0\ 0z60uC0qH0kN0gT0bZ0Zd2Vi6Po8LuCGzECzG8zP4zZ2ze0zo0\ zx0zz0zz0zz0zz0sx0im0`b0RR4HG884AA68A84CA0CC0EE0EG\ 0GH0GJ0GL0JE0L80P22R08V0EX0JV0LV0NV0NV2PV6RVARVGTV\ JVVNVVRXVVZVZZ`bbddegeikgmoiqskuvmxzqzzszzuzzvzzxz\ zzzzzzzzzzqzzezvVvkJm`8dR0XERm0uz0ou0ko0gi0db0ZX0V\ R0RJ0NE0J80PE0VH8`LJeRTkVboZZk`Vg`Te`Pb`NZbJXbHTbE\ PbANb8Jd4Gd2Ed0Ad08d0Cd0Ed0Hd0Jd2Nd2Pd4Td4Vd6Zd6`d\ 8dd8edAidAkd6mX2oP0oJ0qC0s40s00q00q00q00o00o00o00o\ 00m00m00m00m00g02d08Z0CV0GR0Pi0Xz4dzCqm4zJ0z00z00v\ 60kE0bL2RT4Hb66iA0qC0xE0zG0zC0z80z62z28z0Gz0Lx0Tx0\ Zv0dv0Zs0Vo4PkELgNHdXCbe8Zo4Vx0Rz0Nz0Lz0Nz0Nz4Nz8N\ uCNmGPeJPZPPTTPLXPE`R6dR0 } 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
